More camera testing

Another quick test with my new camera.
These 3 photos were all taken from the same position in my backyard, with my 100-400 lens.
The first one is at 100mm, the second one at 400mm and the third one also at 400mm using the 1.6 cropfactor.

All three are pin sharp (the originals are anyway, the posted photo is of course a compressed jpg), and the use of rather high ISO values (800-1000-1600) can be neglected.
