Released in March 2012, the Canon EOS-5D Mark III is a professional grade digital single-lens reflex camera (DSLR) from Canon’s EOS camera line. It succeeded the EOS 5D Mark II and was announced on the 25th anniversary of the announcement of the first camera in the EOS range, the EOS 650, and it was also Canon’s 75th anniversary.

Compared to the Mark II, the Mark III has had improvements in resolution with an increase to 22.3 effective megapixels full-frame CMOS sensor. Moreover, the Mark III has a DIGIC 5+ sensor, maximum ISO speed has increased to ISO 25600, there is a new 61-point autofocus (AF) system with 41 cross-type AF points and five dual cross type points. The Mark III also has faster continuous shooting, 63 metering zones, silent shooting modes, a large LCD screen, dual card slots, and improved weather sealing.

There are some known issues with the LCD screen on the Mark III. Accordingly, Canon issued an advisory that stated that when the LCD panel is illuminated in extremely dark environments, the camera’s light metering may be impacted when shooting. In this case, users should request a repair service from Canon and most likely it will be fixed free of charge. Cameras shipped after May 2012 probably do not have this issue as it was addressed by then.
