About this deal

The European Imaging and Sound Association (EISA) named the Canon EOS 1D Mark III the "European Professional Camera of the Year 2007-2008". [5] Problems [ edit ] When experimenting with some files shot in daylight conditions, we found that once the green channel had clipped in the JPEGs, then highlight recovery was impossible from a file exposed 0.33EV more (there's less that 0.33EV headroom above what's in the JPEGs in daylight). However, in the red channel we were able to recover highlights from a file exposed 1EV beyond the point where the channel had clipped in the JPEGs. This disparity means that you can expect to recover around 1EV of detail in the highlights but that color accuracy is likely to drop off after as little as 0.33EV if the green channel has clipped. JPEG version Quoting the bare specs says a lot: 10 frames per second, 10 megapixels, 110 JPEG buffer, three inch LCD, Live View mode, dual DIGIC III processors, automatic sensor cleaning. These are all impressive, but the Mark II N was pretty darn impressive, too. What I'm more excited about is the radical interface improvements that make all this impressive power more accessible to the photographer. If I have to think too much about how to set the camera while I'm shooting, I lose connection with my subject, and the creative process is stifled. The EOS-1D Mark III is the first Canon digital SLR to employ 14-bit analog-to-digital conversion, up from 12-bit in previous models. The AF Microadjustment feature does differentiate between the original, II and subsequent versions of all EF lenses.

For most real world uses, these are non-issues for this camera, but for these comparisons, the 1D III has an approximately .4% disadvantage With the WFT-E2A wireless transmitter, USB 2.0 Hi-Speed external recording media can also be used." Get your exposure setting correct at the lens' widest aperture (makes evaluating the test pictures easier). These figures don't directly tell you how much dynamic range you can capture in a conventional exposure (the results would look pretty flat, dull and risk featuring strange colors in the highlights), but give an idea for how flexible the raw files are. Below we try to give an idea for how much extra highlight detail can be recaptured.

White balance and colour

But, with a new flagship camera sporting a dedicated AF processing unit, I expected improved performance in this area. The shutter is an electronically controlled focal-plane shutter. Its maximum speed is 1/8,000 of one second. The shutter is operated by an electromagnet. Let’s get this out of the way: The Nikon D3s beats the 1D Mark IV on literally every – every– point (photography-wise). Personal Functions consolidated with Custom Functions, resulting in 57 Custom Functions in 4 groups

UNDERSTANDING THE GRAPH This graph shows the brightness values recorded by the test camera when it is used to photograph a stepped graduation wedge. The wedge has transmission values in 1⁄2EV steps ranging from 0 to 12EV. The camera’s exposure is set so the 12EV section in the wedge has a brightness value of 255. Software analysis of the image then determines the recorded brightness values of all the other steps and calculates the camera’s dynamic range. Dynamic range

Operation and Timing

What you need to know about the above comparisons (aside from how to use the mouse-over feature) ... Although the EOS-1D Mark IV is quoted as having an APS-H-sized sensor like its predecessor, it is interesting that the dimensions of the imaging device have actually shrunk marginally from 28.1×18.7mm in the EOS-1D Mark III to 27.9×18.6mm in the new camera. As before, this puts it between an APS-C and a full-frame device, and it produces a 1.3x focal length magnification factor. However, this isn’t the only difference between the two sensors. For many people, the most important point is that the effective pixel count has been increased from 10.1 million to 16.1 million, and this has necessitated a drop in pixel size (in microns) from 7.2×7.2µm to 5.7×5.7µm.
