The Canon EOS 5D Mark II is one of the most highly regarded DSLRs of all time, so the 22.3-million-pixel Mark III upgrade has a great deal to live up to. How will it fare?
With a 61-point AF system borrowed from Canon EOS-1D X, you would expect the 5D Mark III to focus quickly and accurately, and it doesn’t disappoint. In good light, the AF is extremely fast and responsive, and those thinking of buying the 5D Mark III for documentary photography will be more than happy.
In low light the 5D Mark III’s focus also performs well, although without being able to make a direct comparison I didn’t think it was quite as good as that of the Nikon D4. We hope to be able to test the two AF systems side by side when we compare the Canon EOS-1D X against the Nikon D4 in the coming months.
