Read the results and weep. The Canon 6D is now rated as better than the 5D Mk III and 5D Mk II‘s sensors; though really not by much. We can’t wait to get our hands on the 6D. However, we did compare the 5D MK II and 5D Mk III high ISO results; and we also compared them at lower ISOs too.
Which camera are you springing for and why? I’m still sticking with my Mk II.
