All the photos taken were hand held.
Most shot at 200mm, using a Eos 50d.
The rhino picture was shot f3.5, 1/640s at iso 100 hand held.
I dont like the area at the bottom of the picture which is going out of focus, I have tried 3 of these lenses and they all do the same. Although not on every shot.
I dont like messing about in photoshop to much, only when I do weddings and commercial stuff. For my own photos I want to shoot the scene as the camera captures it. All files shot in Raw with no change to the orginal file apart from a change to JPEG.
Focus was centre, with auto white balance, shot in AV mode.
Im not sure now if this is more to do with the 50d focus zones than the lens ?
