Canon announced their new “enthusiast” level full frame camera –  EOS 5D Mark III on March 2, 2012. It is the replacement of the previous model 5D Mark II and although there are no many new features, Canon have listened to their customers and “fixed” the major things they were criticized for – auto-focus, weather sealing, shooting frame rate, etc.
I won’t describe the detailed characteristics of this camera in details as you can see those at so many places online.
