Long awaited Canon 5D MKIII comes with a long list of improvements compared to its predecessor Canon 5D MKII.

New 5D MIII features compared to 5D MKII

  • new Digic 5+ processor: 6 fps in RAW+JPG mode, new noise reduction algorithms for higher ISO
  • 22.3MP full frame (36x24mm) CMOS sensor – almost no change in images size vs. full frame 21 MP @5D MKII
  • ISO: standard 100-25600, expandable to 104,200 – much better sensitivity in low light than Canon 5D MKII
  • New: 63-zone dual layer iFCL metering system. This one is truly exciting. New Intelligent Focus Color Luminance Metering system integrates with the focusing and take in account both New: color and luminosity near chose AF points! Evaluative, center-weight, partial or spot metering modes
  • New: 61 point High Density reticular autofocus vs. 9 points in 5D MKII. The new AF system is sensitive in extremely low light scenes – up to EV-2
  • 100% coverage optical view finder vs. 98% in 5D MKII
  • 3.2″ TFT LCD with 1.04M dots resolution vs. 3″ LCD with 900K dots
  • New: finally, dual card slots! CF + SD
  • New: built-in HDR mode. I love this one.
  • New: silent shutter mode
  • exposure compensation in +/- 5 stops in 1/3 or 1/2 increments vs. +/- 3 stops in 5D MKII
  • Video: 1920 x 1080 (Full HD): 30 fps (29.97), 25 fps, 24 fps (23.976),  1280 x 720 (HD): 60 fps (59.94), 50 fps, 640 x 480 (VGA): 30 fps (29.97), 25 fps
  • New: Multiple exposure mode for cinematic-style images: additive, average, bright and dark

Verdict: fantastic tool for low light shooting, optimized for professional videography.

Note that the actual spec above was changed since the below commercial video was released. Smaller 22 MP sensor (and not 28.2MP like advertised, 6 fps and not 8 fps). In any case, Canon 5D MKIII with its current specification is a great machine to work with.
