I've had my 7D for a few months now, so I've had the time to get used to it's complicated AF system/setup. Having seen various posts of user error I wanted to give myself time to learn it properly.
The problem is I just can't seem to get consistent shots.
I've just got the camera and lens back from Canon. Canon have apparently adjusted both camera and lens (24L II).
All these shots were taken at F1.4 in AV mode, single focus, centre focus, tripod etc. In most I turned the ISO up to 400 to achieve a fast shutter. Each photo was taken 4 times, the first 3 all with these settings, the 4th shot was taken using live view zoomed in at 10X (live view is always bottom right).
As you can see all examples using live view are spot-on (I understand live view works on different principles, so although I'm not comparing them I've used live view as a good reference shot). However the other 3 are all inconsistent. Some in focus some out. My initial thoughts were that the camera may need some Microadjustment, however, the shot of the shoe shows focus is pretty much spot on (although finer inspection shows some small variations even in this high contrast black/white focus point).
I didn't want to use test charts so all the shots are real taken in real life situations.
Is this normal or am I expecting too much from the camera/lens?
