Yesterday I took my uncle's "new" 70-200mm f2.8E FL ED VR with my F100, shot a couple of photos with it at f2.8. When I was going to change the aperture rotating the dial it didn't change.
Afraid it was something with the camera I've started with changing lenses and with my 50Mm f1.8G everything was alright.
Switched back to the 70-200mm and the same earlier problem happened. Switched the shutter speed and aperture dials and the aperture was still at f2.8
Is that any incompatibility between the F100 and this last 70-200mm model?
Forget to say that with my D750 the 70-200mm works just perfect
Went to Ken Rockwell's page and under the Compatibility tab of the 70-200mm it says that the E lenses only are able to shoot at f2.8 with DSLRs/SLRs prior to 2007
