From Photo.net by Bob Atkins, comes this in depth review of the Canon 5DM3.
On March 2nd 2012 Canon announced the Canon EOS 5D MkIII, (compare prices) as an upgrade of – but not a replacement for – the EOS 5D MkII. Among the major new features of the EOS 5D MkIII are:
- A new 22.3MP CMOS sensor with a gapless microlens, 8 channel readout and low noise
- A new 61 point AF system with 41 cross sensors (same as EOS 1D X) with AF to -2EV
- A 63 Zone iFCL metering (same as EOS 7D)
- Native ISO settings of 100-25600 with expansion to 50-102400
- A new Digic 5+ processor (30% faster than Digic 5, 17x faster than Digic 4)
- 6fps continuous shooting
- In-camera HDR. 3 images taken at +/- 3 stop intervals with in-camera image alignment
Currently (July 2012), the EOS 5D MkIII sells for around $3450 and the EOS 5D MkII sells for around $2100
There were a host of other features that were upgraded or added, but the new sensor, new AF system and new processor are the major advances which enable many of the other upgrades such as faster shooting (6 fps vs 3.9 fps) and more extensive in-camera processing. With a processor 17x faster than that in the EOS 5D MkII, real time chromatic aberration correction is now available for JPEGs, and in video modes the extra processing power enables better moire fringing correction.
Outwardly the EOS 5D MkIII resembles the EOS 5D MkII quite closely, but the user interface is closer to that found on the Canon EOS 7D, with a similar menu structure and control layout….MORE of this extensive review here
