Hands on: Canon 5D Mark III Review
Posted on by Thomas De Maesschalck
The body of the 5D Mark III is largely unchanged from the Mark II's, but there are a few key differences. The pentaprism lump on the top for example is a little larger and more rounded to accommodate the AF module which is 2.5x larger than the one in the Canon 5D MK II.
