I’ve found two things that I forgot to mention in my previous post and which add to the usability of the camera substantially.
First, the edges of the histogram(s) are marked with white lines. This is a first time the histogram is actually readable on a Canon body. Well done.
Second, custom shooting modes (C1-C3 on the mode dial) are now actually usable. Previously if I set any of the modes and modified any setting (such as aperture or exposure compensation) the camera automatically updated the custom mode. Now on the Custom shooting mode (C1-C3) screen you can turn off this auto-update. Actually ‘disabled’ is the default.
I have my custom modes set as follows:
C1 – birding: Av, f/2.8 (this gets updated to f/4 or f/5.6 depending on whether or not I have the 1.4x attached to my 500/4), ISO 400, AI Servo AF, 61pt AF with center point as default.
C2 – landscape auto: Av, f/8, ISO 100, One Shot AF, mirror lockup activated, center AF point selected.
C3 – landscape manual: M, f/8, 1/60, ISO 100, One Shot AF, mirror lockup activated, center AF point selected.
This way the need for separate mirror lockup button can be alleviated.
