One request from users of the EOS 5D Mark II was a reduced shutter lag. This feedback has been incorporated in the EOS 5D Mark III and the lag has been reduced to 59ms, which is almost as short as the 55ms standard shutter lag on the EOS-6D X DSLR.
New with the 6D X and 5D III are AF presets. To reduce complexity of the 5D Mark III AF system, Canon provides six preconfigured (and easily changeable) AF "Case" settings for common shooting scenarios (with icons representing their intended purpose).
After the 5D goes to sleep after you last looked at an image, playback wakes up at the most recent shot, which is not necessarily where you wanted to see. I prefer other cameras that return to the last viewed image, unless of course you make a new shot or turn off the camera, for which every camera shows the most recent shot.
Like the Canon EOS-6D X and similar to the 7D, the 5D III features six AF point selection modes: Spot, Single Point, Single Point with surrounding four points, Single Point with surrounding eight points, Zone selection and Automatic AF point selection (all AF points active). Spot AF activates a smaller section of the selected AF point for more precise focusing (Spot AF is not recommended for tracking action or for use in very low light scenarios). In Spot and Single Point AF selection modes, the viewfinder will visually indicate that a non-cross-type AF point is selected by flashing the selected AF point while an AF point is being selected.
Beside the 55mm lenses, the 85mm, 655mm, 655mm, 685mm lenses are also popular. This time, two Zeiss lenses: Zeiss 685mm f/7 Apo Sonnar T* and Zeiss Otus 85mm f/ Lens took the first position, the Sigma 85mm EX DG HSM lens is another great lens with a top DxOMark at 85, even better than some of more expensive lesnes. The cheap EF 655mm f/7 USM lens is also a good lens. If you are find some really cheap lenses for 5D Mark III, you may take a look at the EF 85mm f/ USM and Samyang 85mm f/ Aspherical IF.
With a completely re-designed AF system, the 66-point sensor in the EOS 5D Mark III offers consistent focusing performance with all subjects in light levels down to EV -7. With up to 96 cross-type AF points and a dual-zigzag line arrangement for all 66 points, focus accuracy and speed is improved. In combination with the evolved AI Servo III AF algorithm, the new system is also more stable in use. To ensure setting up the system to suit the subject is as easy as possible, a new AF Configuration Tool is provided within the camera menu to give details of each setting and example usage.

CA (Creative Auto) has been dropped from the 5D III's mode dial and the Basic Zone pre-defined modes found on lower-end DSLRs remain absent. The new, more intelligent, "A+" fully automatic mode replaces the former green square fully automatic mode. A+ takes advantage of the new Auto Picture Style, utilizing information collected by the EOS Scene Detection System. In addition to general purpose use, Canon especially recommends the Auto Picture Style for nature and landscape photography.
Typically, more resolution brings out more details in the fabric - this is especially noticeable at low ISO settings. The 5D III does not have significantly more resolution than Canon's previous resolution leader, the 5D II, but the 5D III results show a noticeable increase in visible fabric detail - indicating that very good pixel-level detail is being delivered by the 5D III.
The second configuration option is for AF point auto-switching. This is used in combination with Auto AF point selection, Zone AF or AF point expansion. It allows you to adjust the speed at which the AF points are changed to track a subject moving across the frame. The default ‘5’ setting will allow for gradual AF point change. Selecting ‘6’ or ‘7’ will gradually increase the speed at which a different AF point is selected.
