Canon EOS 1D MkIV: Features
There are a number of exciting new features on the new EOS 1D MkIV, notably the AF system, high sensitivity to ISO102,400 and 1280x1080p full HD video capability. Aimed at the professional photographer, Canon are confident that the APS-H format is the optimum sensor type for the target audience and say that professionals asked for this specific one. Priced at £4499.00, the camera sits a few hundred pounds above the recently announced Nikon D3s which shares a few of the same features such as the HD video (although not full HD) and the ultra high ISO.
The 16Mp CMOS sensor was built specifically for the EOS 1D MkIV as was the brand new focusing system and Canon are confident that this new module doesn't have the same issues that plagued previous models. Lee Bonniface, Country Director for Canon UK, said that they built the sensor and focusing module in house so that if there were any problems, they could be amended quickly. Canon have added a dedicated micro processor for faster performance which, Canon say, will provide precision tracking and it also has a new Spot AF mode for pinpoint focusing. A new orientation feature is available which will allow the user to preset the focus point, then the camera will retain the location of the focus point, even if you change the orientation, which sound slike it will make off centre shooting even easier.
Thanks to radical new advancements in technology, Canon have managed to push the sensitivity rating to ISO102,400, an incredibly high number that essentially enables you to shoot and pick out detail in near pitch black. What do Canon think about Nikon beating them to the release of this new technology? We asked David Parry, Product Intelligence Professional for Canon UK in a video interview and you can see his response there.
Canon EOS 1D MkIV: Build and handling
New advancements have been made in the build quality, which is refreshing to see as too often the focus (no pun intended) is on the features. The screen has been redesigned on the back of the camera and is new for the EOS 1D MkIV, it's still a 3in TFT LCD with a 920,000dot (307,000px) resolution, but the surface has a new anti-glare coating that eliminates all but the ridiculously stubborn reflections. Take a look at the product shots we got of the camera, below, and you'll see the images were taken with flash but the screen is still easily visible.
76 weather seals have been added to the camera and if you use it in conjunction with weather sealed EF lenses, Canon say this will make it fully weather proof. If not, they can't guarantee moisture not getting through the lens mount.
Larger buttons have also been added for easier use and in the ten minutes we got to play with the camera, it certainly felt the business. It feels lighter than it looks but it's around the same size and weight as the MkIII. Pressing the shutter is a joy with a rapid, positive shutter curtain speeding over the sensor. I tried the camera with a 24-70mm USM L lens and the focusing is fast and accurate.
