I have three lenses for the XT-1
10-25 F4
56mm F1.4 ADP
50-140mm F2.8
The Defender shot was taken with the 50-140mm F2.8, which is tack sharp, certainly as good as the Canon 70-200mm 2.8 IS for sharpness
The Brute shot was taken with the 56mm F1.4 ADP. Not really a fair comparison to anything, as that is the finest portrait lens I have ever shot with, particularly with the ADP (Apodizing) filter. The bokeh is creamy deliciousness. It is also $1,600
I will say that the XT-1 is not a better camera then my 5D MKIII. I have decided to keep both. The 5D is a much better action camera and infinitely better in low light. For commercial shoots and traveling out of the vehicle, I still grab the Canon. For the motorcycle or pure photojournalist work (i.e. low profile), I grab the XT-1. I will also say that the Fujinon lenses are exceptional and half the price of a comparable Canon L. They have exceeded my expectations and I love the sharpness. I believe that Fuji is doing a much better job matching lenses to camera bodies, both from a tolerance standpoint and the in-camera corrections.
