Canon EOS 5D Mark III
Features a 61-Point High Density Reticular AF system
Similar to the AF point selection options offered in the EOS 7D and EOS-1D X camera models, the EOS 5D Mark III offers 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.
Complementing the EOS 5D Mark III camera's 61-point AF system is Canon's 63-zone iFCL dual layer metering system. The 'FCL' stands for 'Focus, Color and Luminance,' and references the fact that the metering system not only measures color and luminance data, but also analyzes the data provided by each point of the AF system. Canon's iFCL metering keeps exposure levels stable from shot to shot, even as the light source changes. The camera's autofocus information is also used to help determine which area of the scene is of greatest importance in determining exposure.
The EOS 5D Mark III camera features a built-in HDR mode, merging three images at various exposure levels into a single image, in-camera, for stunning photographs of landscapes and architecture with enhanced tonal gradation beyond the range of the naked eye. The exposure levels in the camera's HDR mode can be set to cover a range of up to ±3 stops, in a choice of five settings: Natural, Art Standard, Art Vivid, Art Bold and Art Embossed providing unique visual effects. Individual source images can be saved as separate files, and the HDR mode has an optional automatic alignment function that can be useful for hand-held shooting. The EOS 5D Mark III's standard Auto Exposure Bracketing function has been upgraded to allow for up to seven exposures per sequence, and exposure compensation can now be set for up to +/- 5EV.
Multiple Exposure Mode
The EOS 5D Mark III is the second EOS Digital SLR after the EOS-1D X to feature Multiple Exposure capabilities with the ability to combine up to nine individual images into a single composite image, with no need for post-processing in a computer. Four different compositing methods are provided for maximum creative control, including Additive, Average, Bright and Dark. Compositing results can be viewed in real time on the camera's LCD monitor, and there is a one-step Undo command that allows photographers to delete an image and try again if desired. The EOS 5D Mark III camera's Multiple Exposure mode even allows photographers to specify a previously captured RAW image as the starting point for a new Multiple Exposure composite image, or shoot continuously when photographing moving subjects.
A new feature seen for the first time in the EOS System on the 5D Mark III is Comparative Playback allowing photographers to display two images side by side on the camera's 3.2-inch LCD screen. The images can be displayed with a histogram to check exposure levels, or magnified to check for focus or facial expressions.
