Here is a typical example of what IQ is like for the 300mm f/2.8 II with a series III 2xTC attached. There is no PP on these, no unsharp mask etc, changing of contrast etc. The 5760x3840 full frame of the 5D III is reduced to 1200x800 to have it on screen. There are 100% crops of the centre and the head to show the level of resolution. These are tiny: 210x163 pixels at the centre and 763x619 of the head.
