Canon was making a play for sports and news photographers, many of whom had found the firm’s previous digital offerings frustrating. And resolution of only 4MP, too, rather than the 6MP they’d been hoping for, not to mention APS-H rather than full-frame – what gives, Canon?! This is probably OK if not doing sports though compactness could be an advantage for news.Some photographers questioned the use of a CCD sensor, rather than the newfangled CMOS type of sensor they’d started seeing in other cameras – not least Canon’s own D30. Sure, 10 fps is great, but so is a usable photo of night HS football at ISO 12800. That's why the 1.3x crop is so baffling on a camera like this when Nikon's flagship has full frame. You have to capture and freeze the action as it's happening. In photojournalism, especially sports, especially in low-light situations, you can never have too much ISO flexibility because you have to keep the shutter speeds so fast. And I still do a lot of amateur shooting as an enthusiast even though no one is paying me. I have since changed careers, but I still think I know at least a thing or two about what pros look for in a camera like this. So I have some LIMITED photojournalism experience with a Nikon D1 kit. I also switched off between covering news and high school sports. 39 cross-type for F2.8 or faster lensesīack in 2002, I was a reporter for a small newspaper, and we didn't have dedicated photographers, so I was a reporter / photographer.Sadly the release of the EOS-1D Mark III coincided with one of the busiest periods in dpreview's history (including an office and studio move, staff recruitment and training and more consumer level DSLR launches than ever before), meaning that, although much work was done and thousands of sample shots were taken, our review of that camera was never completed. The EOS-1D Mark IV is the highest pixel-count 1D series, with 50% more photosites creating a 26% increase in resolution over the previous model. If you consider that this is almost the same resolution as offered by the last generation of Canon's studio-targeted camera, the 1Ds Mark II, but with the ability to shoot twice as fast, then you start to appreciate what this camera is promising to do. This may not seem like many in the era of 25MP full-frame DSLRs and 14MP compacts, but it's a lot when you consider the Mark IV still has the ability to shoot at 10 frames per second. The 1D Mark IV retains its predecessors' 1.3x crop, APS-H sensor size, but this time increases its pixel count to a whopping 16MP. The AF point selection method has also been revised, both for manual selection and for automated selection with subject tracking via the new AI-Servo II system. Although the 45 AF points are arranged in a layout that dates back to 1998's EOS 3, the 1D Mark IV uses a totally new AF sensor with 39 cross-type points that are sensitive both in the vertical and horizontal axis. Since then, however, a combination of engineering revisions and user education have meant that many shooters have been able to use the camera without any problems - Canon admits there have been issues, but the woes that were so widely reported early in the camera's life span are unlikely still to be affecting nearly as many users as its internet reputation might suggest.Ĭanon is clearly hoping to assuage any doubts still lingering after the '1D III Affair' by introducing a new AF system. These issues, combined with the coincident arrival of the Nikon D3 that offered, for the first time, an equal level of AF sophistication, brought into question Canon's long-held position as AF front-runner. Those problems, which appear to have come from a combination of manufacturing error, increased complexity of AF customization and the AF sensor occasionally being overwhelmed in bright conditions, have become notorious. Whereas, in the past, Canon's flagship models have been a fairly safe bet, autofocus problems with the 1D Mark III have cast a shadow over the range. However, more than previous 1D series cameras, the 1D Mark IV has a lot to prove. And it's this consistency of design, which extends to the AF pattern and much of the control layout, that helps to explain the name - the Mark IV really is the current point in an evolutionary process, rather than a wholly separate model. It retains the two-grip form factor of the original, 4MP EOS-1D launched in September 2001 (itself building on the integrated grip of the film-era EOS-1N RS, also the first to offer 10fps shooting, albeit without AF between shots). The Canon EOS 1D Mark IV is the fifth generation of Canon's speed-orientated range of professional DSLRs.
