Canon Announces 21.1 Megapixel 5D Mark II





With their ground-breaking full-frame 5D nearly three years old, the replacement for the model that created a new market segment has been expected at every photo event for the past year or more. Canon has certainly played this excitement to the hilt, including a clever web teaser that showed a little more detail every few days. To their credit, Canon managed to keep the final details about as secret as we have ever seen in this market. Now, with just a few days until Photokina begins, Canon has finally announced the Canon 5D replacement, to be called the 5D Mark II. 

CANON U.S.A. INTRODUCES THE HIGHLY ANTICIPATED EOS 5D MARK II DSLR CAMERA FEATURING FULL-FRAME HD VIDEO CAPTURE 

The Canon EOS 5D Mark II Escalates Full-Frame Digital SLR Photography to the Next Level with HD Movie Recording Capabilities, DIGIC 4 Imaging Processor, and 21.1 Megapixel Resolution
 
LAKE SUCCESS, N.Y., September 17, 2008 – Canon U.S.A., Inc., a leader in digital imaging, today introduced the EOS 5D Mark II Digital SLR camera, the long-awaited successor to Canon’s highly popular EOS 5D, introduced in 2005. Building upon the qualities that made the EOS 5D camera so successful, Canon has coupled the creative power of a full-frame CMOS sensor in a relatively compact and affordable camera body, together with groundbreaking HD video capture that opens the door to a much wider range of imaging possibilities for photographers. Along with the ability to capture full HD video clips at 1920 x 1080 resolution, Canon’s EOS 5D Mark II Digital SLR camera features a 21.1-megapixel full frame 24 x 36mm CMOS sensor, DIGIC 4 imaging processor and significantly lower noise, with an expanded sensitivity range from ISO 50 to ISO 25,600.
 
“The anticipation surrounding the launch of this camera model has exceeded our greatest expectations, and we believe our loyal customers will be awed by the level of innovation and features built into the new EOS 5D Mark II Digital SLR. Once they have the chance to experience the camera, we believe they will agree that it was worth the wait,” stated Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A.
 
Among the many advancements in Canon’s new EOS 5D Mark II camera is the Company’s proprietary DIGIC 4 Imaging Processor that powers the camera’s fast 14-bit analog-to-digital conversion for smooth color tones and exceptional gradation. The Canon EOS 5D Mark II Digital SLR offers a full-frame 24 x 36mm, 21.1 megapixel CMOS sensor and continuous shooting at 3.9 frames per second (fps) for an unlimited number of full-resolution JPEGs to the capacity of the memory card or up to 14 RAW images in a single burst when using a UDMA CF card.

The camera includes a 15-point Autofocus (AF) sensor with nine selectable AF points plus six additional Assist AF points (three center AF points sensitive to f/2.8 lenses) with enhanced light source detection and AF microadjustment for greater autofocus performance. The EOS 5D Mark II camera also features a large, clear 3.0-inch Clear View LCD screen with 920,000 dot/VGA resolution, four times the pixel count of the EOS 5D camera’s 2.5-inch screen, for enhanced clarity and color when viewing images. The new camera is equipped with a high-performance, high-magnification optical viewfinder providing 98 percent coverage, giving a new dimension to the saying, “what you see is what you get.” Professional photographers will also appreciate the enhanced 150,000-cycle shutter durability of the EOS 5D Mark II camera.
 
Canon, the first company to introduce a full-frame digital camera, has improved the EOS 5D Mark II Digital SLR camera’s newly developed full-frame CMOS image sensor. Utilizing proprietary Canon technology, the Company has reduced noise and expanded the sensitivity of the CMOS sensor up to ISO 25600, which is three full stops higher than the ISO 3200 limit of the original EOS 5D camera. Although the individual pixel dimensions of the EOS 5D Mark II camera are the same as the 21.1-megapixel CMOS sensor used in the EOS-1Ds Mark III digital SLR, the new sensor incorporates an improved output amplifier and a more advanced color filter that improves light transmission while retaining excellent color reproduction. By applying the same kind of advancements in sensor design and image processing technology as the recently introduced EOS 50D camera, but at higher resolution and with larger pixels, the EOS 5D Mark II achieves the highest level of image quality of any EOS Digital SLR released to date.

With the combination of its improved CMOS image sensor and the powerful new DIGIC 4 image processor, the Canon EOS 5D Mark II camera provides ISO speeds from ISO 100 up to ISO 6400 in 1/3-stop increments, along with two high-speed settings – H1 and H2 – of ISO 12800 and ISO 25600, respectively, as well as a low-speed setting of ISO 50. The full-frame sensor maximizes the performance of Canon EF lenses, the world’s largest selection of autofocus lenses.

HD and SD Video Capture
Canon has taken its expertise in imaging, photography and video capture technology to a new level with the EOS 5D Mark II Digital SLR. Answering the question of where SLR technology is going next, the EOS 5D Mark II features 16:9 Full HD video capture at 1920 x 1080 pixels and 30 fps as well as 4:3 standard TV quality (SD) video capture at 640 x 480 pixels and 30 fps, both capabilities appearing for the first time in a Canon SLR camera. Video capture is part of the camera’s Live View function, using the Picture Style that has been set for Live View still image shooting. This allows skilled photographers and cinematographers to adjust image sharpness, contrast, color saturation and white balance, and have those settings apply to the movie image. When recording video, the camera’s rear LCD screen can be letter-boxed by a semi-transparent border to match the aspect ratio of the movie recording size. Moreover, the EOS 5D Mark II camera’s HD video capability enables new levels of creative expression through its unfettered access to the complete line of more than 60 Canon EF lenses, which provide an incredible variety of visual effects including everything from ultra-wide-angle and fish-eye to macro and super-telephoto, including many large-aperture L-series professional lenses that can keep the main subject in razor-sharp focus while blurring the background beyond recognition.
 
The EOS 5D Mark II will record video up to 4GB per clip or a maximum continuous movie capture time of 29 minutes and 59 seconds, whichever comes first. Depending on the level of detail in the scene, a 4GB memory card can record approximately 12 minutes of video at full HD resolution or approximately 24 minutes in standard definition.  The camera includes an HDMI (High-Definition Multimedia Interface) output to display crisp, clear images on a High-Definition TV. Video clips are recorded in .MOV format using an MPEG-4 video compression and sound is recorded using linear PCM without compression. The new camera features an input terminal for external stereo microphones as well as a built-in monaural microphone for convenience. 
 
Live View Shooting
For both still images and video, the Canon EOS 5D Mark II camera features Live View, one of the most sought after features in digital SLRs today. The 5D Mark II features three Live View AF modes – Quick, Live and Face Detection Live mode – for capturing either still photos or video, each with its own attributes. Quick mode automatically sets One-Shot AF using the camera’s phase detection AF system. It also allows users to select the AF point, even while the Live View image is displayed. Although the camera’s reflex mirror must be lowered briefly to take an AF measurement in Quick mode, it is the fastest way to set focus automatically when the 5D Mark II camera is set for Live View.
 
Live mode uses contrast-detection AF with the image sensor and here, as with Quick mode, users can change the AF point using the Multi-controller. Face Detection Live mode uses contrast AF to recognize human faces. When multiple faces are detected, the largest face closest to the center of the frame is targeted as the AF point. While Live View is engaged users can still change settings including the AF mode (Quick, Live, Face Detection Live mode), drive mode, ISO speed, Picture style, White Balance, and more.
 
Peripheral Illumination Correction
The Canon EOS 5D Mark II Digital SLR camera automatically conducts peripheral illumination correction when shooting JPEG images, a function that previously could only be accomplished through post-image processing using software such as Canon’s Digital Photo Professional, which Canon supplies at no extra charge. Peripheral illumination correction evens brightness across the image field, making an image of a blue sky even toned throughout and reducing light fall-off at image edges. This new feature essentially eliminates one of the limitations of previous full-frame digital SLRs.
 
Auto Lighting Optimizer
Canon’s enhanced Auto Lighting Optimizer technology helps ensure each picture’s subject is clearly visible by analyzing image brightness and automatically adjusting dark areas in images so that they appear brighter. This function is ideal in high-contrast situations such as urban landscapes captured on sunny days, where the tops of buildings are brightly lit while street level details are obscured by heavy shadows. In this type of scene, the 5D Mark II camera’s Auto Lighting Optimizer technology preserves accurate exposure of the highlights while opening up the shadow areas for a more pleasing tonal rendition.
 
Canon’s New Creative Auto Mode
Recently introduced with the new EOS 50D, Canon’s “CA” Creative Full Auto setting can also be found on the EOS 5D Mark II Digital SLR camera’s mode dial. This setting allows users to make image adjustments such as aperture or shutter speed through an easy-to-understand navigation screen on the camera’s LCD menu, allowing them to “blur the background” or “lighten or darken the image.” These easy-to-understand image options allow photographers to experiment with image options while still shooting in an automatic mode.
 
Two Small RAW Formats
For photographers seeking the flexibility and creative possibilities of shooting RAW format images, without the large file size, the Canon EOS 5D Mark II Digital SLR camera offers two more manageable file size options with sRAW1 and sRAW2 recording formats. At the sRAW1 setting, resolution is 10.0-megapixels with a file size that is approximately 25 percent smaller than a standard 21.1-megapixel RAW image. With the sRAW2 setting, resolution is 5.2 megapixels at less than half the file size of a standard RAW image, retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images. Wedding and portrait photographers, in particular, will appreciate the options of variable resolution and file size which allow them to fine-tune the 5D Mark II’s operation for their specific needs.
 
Silent Shooting in Live View
Canon has equipped the EOS 5D Mark II with two Silent Shooting modes in Live View which will prove particularly helpful to law enforcement officials, and for behind-the-scenes shooting on movie sets. In Mode 1, the camera will shoot with the mechanical shutter open at the beginning of the exposure, using the electronic 1st-curtain function of the CMOS sensor and a reduced shutter-cocking noise, allowing multiple shots to be taken with minimal noise. In Mode 2, to minimize shutter noise during single frame photography, shutter cocking does not occur until the shutter button returns to the half-way position after shooting.
 
EOS Integrated Cleaning System
With the introduction of the EOS 5D Mark II camera, the entire Canon EOS system is now equipped with the highly acclaimed EOS Integrated Cleaning System. The Self-Cleaning Sensor Unit for the Canon EOS 5D Mark II has been upgraded with a fluorine coating on the low-pass filter for better dust resistance.
 
Pricing and Availability
The Canon EOS 5D Mark II Digital SLR camera is compatible with Canon EF lenses and is scheduled for delivery by the end of November. The EOS 5D Mark II will be sold in a body-only configuration at an estimated retail price of $2,699. It will additionally be offered in a kit version with Canon’s EF 24-105mm f/4L IS USM zoom lens at an estimated retail price of $3,499.

New EF 24mm f/1.4L II USM Lens
The new EF 24mm f/1.4L II USM lens is the successor to Canon’s EF 24mm f/1.4L USM professional wide-angle lens released in 1997. Targeting professional photographers, the new EF 24mm f/1.4L II USM lens has been introduced to address the advancements high-resolution digital SLR cameras with re-designed optics and use of a new anti-reflection lens coating called SWC (Sub-Wavelength Structure Coating) to minimize ghosting and flare. Features such as dustproof and waterproof construction that have been adopted make this a high-performance lens with specifications that respond to the demands of professional users. A welcome complement to the EOS 5D Mark II Digital SLR camera, the EF 24mm f/1.4L II USM lens is scheduled to be in stores this December at an estimated retail price of $1,699.

Foxconn Black Ops - Raw, Unadulterated Power

Late last year Foxconn announced their presence in the performance sector with the P35-based Mars motherboard. Like most boards using the P35 chipset, the Mars matured into an outstanding product. In fact, it turned out to be frighteningly close in capabilities to our favorite DFI P35 UT product. On the back of this excellent release, Foxconn has been inspired with the confidence to develop a performance range of motherboards with specific objectives in mind. Given the size of the company and its in-house manufacturing capabilities, the progression into releasing a line of performance-oriented motherboards seems to be perfectly logical.

With over 200,000 employees worldwide, a proven distribution network, and an already established reputation in multiple product lines, one would be lead to believe that competitive volumes of high-end brand motherboard sales will be another notch of success for Foxconn. The mere presence of Foxconn in the performance computer sector at the very least should drive the other big players towards higher levels of innovation - and who knows, perhaps pricing will benefit too. Contrary to that last statement on the subject of pricing, the Black Ops motherboard we're reviewing here today will help relieve you of that irritating bulge in your wallet by setting you back a mere $350 or so.

Okay, so the Black Ops itself is not going to be the cure for ever-increasing high-end hardware costs; let's hope upcoming or future products will fulfill that role. We look at the Black Ops as more of a statement product from Foxconn that announces their presence on the scene, aspiring to win the support of some of the world's top benchmarkers. A few endorsements by well-known and respected individuals can go a long way and can carry enough weight to convince the more discerning among us that something is at least worth checking out.

The pursuit of recognition has lead to Foxconn employing none other than Peter Tan (aka Shamino), who will provide insight into releasing a board built from the ground up with one main purpose in mind: withstand the onslaught of extreme cooling to benchmark and set world records. To the more uninitiated among us, think of this form of usage as drag racing with a processor, memory, and graphics card either for competition or just simply for the thrill. It would be fair to say we can expect a motherboard with toenail curling voltage ranges, multiple cooling options, and rugged power delivery circuits. Let's not forget the customary masses of chipset tuning options via BIOS options that are all deemed essential for extreme benchmarking.

Thus far, we consider the launch of the Black Ops a successful one. The board has broken or holds a number of Futuremark world records and has seemingly gained enough allure to find itself in demand from regular users. It hasn't all been plain sailing though, with all the initial focus falling on out of the box speed rather than "safety", early BIOS releases were set up very tight, and compatibility with certain types of memory modules at launch needed improvement. This left some of the regular users, including us, a little disgruntled. Things have improved with each BIOS release for the 24/7 crowd, although the steep learning curve to mastering the BIOS remains daunting. It takes patience to tune the board, with new users often requiring advice from experienced users to get the most from the board.

On the subject of helping users, Foxconn already seems to have realized that a strong and accessible support staff presence is crucial to ensuring the success of an enthusiast product, as initial launch compatibility issues are often rife on all performance-oriented motherboards. For those of us that are struggling with various configurations, Foxconn employees are available to help users get started and push for BIOS fixes at Foxconn's support forum. Turnaround for such fixes has been lightning fast in most cases, and the board is generally far more compatible overall than it was a few months ago.

It seems there are plenty of positives making up the perimeter of Foxconn's package for the consumer. What we have learned following our quick look at the Black Ops is that teamed with the right components and some perseverance the board is an absolute beast. Before we even continue into this review, let us reiterate that this is an ultra niche product; it's not designed to be particularly mainstream or to offer the best everyday functionality and peripheral compatibility as other boards. This is not to say the board is not compatible or stable - far from it. Let's just say that picking up the groceries and a load of lumber is best left for the SUV and not the Ferrari.

On the plus side, Foxconn will concentrate on overall compatibility qualities on upcoming boards aimed at the mainstream enthusiast market. For now, if you intend to buy the Black Ops and run it in an overclocked everyday configuration, we offer the following advice. Do your homework first, ask questions of support staff and users to find out which components have synergy, and then make your purchasing decisions. Making informed choices will save disappointment later on. Don't let what we say here put you off if you're a die-hard overclocking fan, admire quality, or enjoy tinkering with settings till the cows come home. [Ed: Mooooo!]

With the disclaimers out of the way, we're going to run a few of our standard test suites followed by some benchmarking under cascade cooling to see how the board holds up to the abuse it's built to take.

A Lesson in User Failure: Investigating the Serial ATA Connector

A Lesson in User Failure: Investigating the Serial ATA Connector
Something you learn quickly in this industry is that working as a technology journalist does not make you immune to computer problems or the laws of physics that can be at the root of them. Just by doing our work we tend to break things now and then; overclocked processors become keychains, overheated video cards become surgical knives (make no mistake, PCB is a very capable blade), and gadgets become interesting conversational pieces. Much of this we'll make a passing observation on, but otherwise we don't talk about failures too often.
Every once in a while though, we will break something in a process that's genuinely interesting. Failure is its own reward, it teaches us how to not do something or do something better than we did before. And in those handful of cases, we like to get to the bottom of what went wrong, what we did wrong, and what can be done to avoid the issue in the future. In these cases, you the reader can receive some of our imparted knowledge without needing to also experience the pain and cost of the lesson.
So what have we managed to break this time that we find so interesting that it's worth writing about? We made what is in fact a very common mistake, and nearly turned a week-old hard drive in to a new source of magnets by breaking the Serial ATA connector on the drive. It's the kind of problem that sounds rather trivial, but due to the construction of many SATA hard drives, breaking the SATA connector is a death sentence for the drive because it's impractical-to-impossible to replace it, as it's part of the circuit board if not also part of the drive itself.
It's only appropriate to preface this by saying that we're not dissatisfied with the SATA specification, rather we find ourselves in an interesting situation. The thinner cable is far easier to route in a cramped case than a Parallel ATA cable, it doesn't impede airflow like a ribbon cable, and getting rid of hooking two devices to a single cable was a long-overdue change.
But - and we know we're not alone in this thought - SATA cables and connectors aren't quite as robust as the old PATA design. PATA cables could be worked in to rather impossible situations as the connector was extremely snug fitting, and the cable itself was extremely flexible when it needed to be folded longitudinally; it was hard to set up but also hard to break. We'll still take a SATA setup any day of the week, but we've come to the realization we can't abuse SATA setups like we could PATA setups.
As a consequence, today we'll share with you what we found out in dealing with our problem. What did we do wrong? What can we do about it? And just why is the SATA connector designed the way it is anyhow? Read on to find out.

In Memory Of The Law: The Memory Industry's Legal Problems

In 1890 the United States government passed the Sherman Antitrust Act, a law that formed the bedrock of the United States' policy against monopolies and other unfair forms of competition. In the many years since then, further acts have been passed to amend the law, and the Government has in time made the correction of anti-competitive actions one of its more important roles. What started with the breaking up of truly gigantic corporations like Standard Oil and AT&T has moved on to include dealing with cartels that while not of a single corporation, act at times in manners similar that result in anti-competitive actions taking place.
If we were to take a cursory glance at the computing industry as a whole and try to pinpoint the areas where anti-competitive legal issues were likely to occur, we'd look at areas like CPUs and GPUs, where only a couple of serious competitors exist in each, or operating systems, where Microsoft has and continues to have a de facto monopoly. While these areas do in fact have issues, we would be missing an area that has shown some of the worst behavior. It turns out that the memory industry is one of the greatest offenders.
Generally speaking, it's counter-intuitive to see the memory industry as being a hotbed of legal woes due to the highly competitive nature of the market. With the JEDEC association setting very rigorous standards for RAM, products are quite literally perfectly competitive (from a non-overclocker's point of view): a part specified to meet a certain JEDEC RAM standard should be just as good as any other part that adheres to the same specification. As a result, OEMs can and do switch RAM on a regular basis depending on who can supply it at the lowest cost, and as a result we usually see the memory market operate as it is: a highly competitive market in which multiple companies supply the same good.
But didn't we just say that the memory market is one of the greatest antitrust offenders? Yes, for in spite of the memory market being very cutthroat, it's also an industry that is subject to highly volatile demand. It can be extremely profitable as a result when demand is far outstripping supply and it takes years to bring new fabs online to produce additional memory. It's the profitability of these periods that keeps nearly a dozen major companies in the business. With such volatility however, it also opens the window for manipulation of this volatility - if now is not a boom year, why not make it one?
Over just the last decade, the memory industry has been through no less than three major shakeups. The first is the infamous and now settled Rambus patent case, started in 2000 when Rambus asserted that it held patents on technology used in DDR RAM and wanted royalties as such, only to be found guilty of breaking antitrust and deception laws in acquiring these patents and covertly trying to influence the memory market. The second case involves the "Big 10" memory manufacturers colluding to keep RAM prices artificially high between 1998 and 2002, to which they were found guilty. Finally, a new investigation has opened up as of this year into the flash memory market, where the Justice Department is trying to figure out if there is evidence of collusion and price-fixing there too.
Today we'll be taking a look at the latter two actions, one just wrapping up while another begins. What exactly went on in these cases? How are or potentially were consumers hurt by all of this? What has been done to punish the offenders and to correct the market? Let's find out.

The Gigabyte GA-X48T-DQ6 - Redefining the High End?

Gigabyte's motherboards are always products we look forward to, especially the budget/midrange solutions. These boards represent features and performance that often belies their price. Recently, Gigabyte has also been making strides into the high-end of the motherboard market. The first product of Gigabyte's aspirations using an Intel chipset was the GA-X38-DQ6 motherboard. The board was generally well received and had a decent set of features and performance. In short, we would not hesitate to recommend the GA-X38-DQ6 for a top-end overclocking or gaming system.
The only gripe about the GA-X38-DQ6 by hardcore overclockers is that it has slightly lower clock for clock performance when compared to other X38 motherboards. The GA-X48T-DQ6 we are reviewing here today obviously uses Intel's higher speed binned X48 chipset. Instead of just plugging the X48 into the existing X38 board design, Gigabyte listened to the concerns of users. Gigabyte made a wise decision to refine the existing X38 motherboard design to take advantage of the additional performance potential of the X48 speed bin.
A few months ago our feelings about the X38 chipset were a little mixed; we felt it really did not bring anything exciting to the table. As time has progressed since the chipset launch, motherboards based on the X38 chipset have become our favorites for overclocking, for many different reasons. In fact, the primary reason is that they have proven to be extremely reliable for overclocking use on a 24/7 basis. Once set up correctly, we find these boards to be able to run the same settings day-in day-out, so long as the demands are reasonable. Naturally for the budget minded users, we would still lean towards the P35 chipset as far as single graphics card use goes. However, as the focus shifts, the prices of X38 based boards should come in lower than the higher end P35 boards, making the decision of which one to choose all too easy.
It really is no surprise that Intel CPU's are at their very best when teamed with Intel chipsets. Understandably, the release schedule of all the tier-one suppliers includes motherboards in either DDR2 or DDR3 format using either the X38 or the updated (speed binned) X48. While we have always felt that the synthetic performance figures of the X38 in DDR2 form have been lower than expected, the 3D performance gains over more attractively priced P35 chipset is always apparent. In DDR3 format the X38/X48 is the performance choice, and outperforms the DDR2 boards overall in just about every benchmark… well, at least by a few percent. Of course, this slight increase in performance comes at an expensive cost, with DDR3 memory prices being double that of DDR2 - if not more - depending on what speed bin you order.

A couple of weeks ago, we were able to provide a small glimpse of the high-end extreme benchmarking that the DDR3 based GA-X48T-DQ6 is capable of in current form. We managed a clean sweep of current single card 8800 GTS 640MB 3DMark world records using this motherboard. The board's overclocking performance impressed us, but using a motherboard in a normal operating environment like most users is always an important part of our testing. Things were still quite rough around the edges at the time of the preview. In fact, we were unable to install Microsoft Vista due to our boot drive being unrecognized as a valid partition after Vista had completed formatting the drive. Issues like these are not new to us; most of the boards always need BIOS updates in their early stages. Our real concerns at the time revolved around non-working memory dividers and general unpredictability when overclocking.
Things have certainly progressed in some areas since our first look; we have received a few BIOS spins addressing improvements and compatibility in several areas. In truth, this has not been the most solid pre-release board we have received of late. We were actually beginning to feel a little spoiled, as most of the X38 based pre-release boards we received have been remarkably ready for good overclocking right from the get-go. In spite of this, we decided to keep the length of time between the first look and our review as short as possible. This is especially important in light of the fact that we are endeavoring to provide users with meaningful BIOS insights before Gigabyte releases the board. Naturally, this process takes time, but we think it's well worth the wait considering the options available in the BIOS. Indeed, we are intrigued to see what Gigabyte has managed in bringing performance and reliability together in one package using the X48 chipset.
