Important details on the introduction page should be read prior to viewing these crops. Those details are not repeated here.
Please note that the 135/2L + TC14 combo was shot at ISO 400, and so its images can be slightly grainy.
Special note on f/8 - f/11
There is a loss of contrast and detail at center when stopping the 70-200mm f/2.8L IS II down, starting subtly at f/5.6 and then rapidly worsening at f/8 - f/11. This problem was confirmed on a different target on a different day, read more. Further testing (6 totals samples) shows that this problem is lens specific, so check your lens carefully.
