The Canon ROS 5D Mark III was released in 2008 as an update to the highly regarded EOS 5D Mark II. Built on the success of its predecessor and featuring the most advanced autofocus system Canon has released to date from its EOS-1D X line, the Canon EOS 5D Mark III is a rather promising upgrade to the 5D line.

Differences Between Canon EOS 5D Mark III and Canon EOS 5D Mark II

Most of the key specs are substantially upgraded compared to the 5D Mark II. The new sensor, coupled with Canon’s latest DIGIC 5+ processor, offers a standard ISO range of 100 – 25,600 that’s expandable to 50 – 102,800. An 8-channel sensor readout enables continuous shooting at 6 fps. The shutter is rated to 150,000 cycles and has been refined for quieter operation; the Mark III also inherits the ‘silent’ shutter mode previously seen on the 1D series.

Viewfinder coverage is a full 100%, and the 1040k dot, 3:2 aspect ratio 3.2″ LCD screen has improved anti-reflection properties and a hardened glass cover to protect against scratching. And let’s not forget that 61-point focus system from the 1DX – the first time Canon has put its top-spec AF sensor into a non-1-series camera since the film-era EOS 3.

My Portrait Shoots with the Canon 5D Mark III

I used Canon 5D mark 3 for some of my portrait shootings, and I am really happy about the result. Mostly I used Continues Light with High ISO. The result is amazing. From these links, you could see some of them in my Gallery.
