Hello Richard,
Yes the 5 degree rotation uncertainty was indeed of the focus ring.
I guess there is a good chance, reading all the comments, that the 5D
I used in the store was out of alignment. I suppose when (if) I get
one I shall have to test the focus pretty thoroughly.
Others have commented on alternative screens too, thanks.
Regards,
Akhil.
