I'm at the Alligator Farm and met a photographer having trouble with a 400 2.8 Seems the rotating collar is stuck and only rotates 1/4 of the way L/R
From looking at it seems the stops are hitting the collar ... could it be the bearings? Any suggestions?
Al,
Loosen the 4 screws securing the lens collar, and see if it falls back into place. Worse case you can fully remove the screws and ball bearing w/ spring from the collar.
I will see you tomorrow at the AF and help further if need be.
Best,
Chas
Thanks Chas ... will see you tomorrow
... btw for the time being I was able to turn the head upside down and its working !!! Really looks weird but getting the job done !!!! :)
