• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

It was somewhat unexpected, but I discovered last night that there is serious vignetting with the Tokina 16-28mm and the Mark IV. The lens itself didn't go on easily. It fit a bit too snugly. I don't know why or in what way, but it seems Canon changed something with the lens mount on the Mark IV. I never had either problems with my Mark II.

Has anyone else who has this camera+lens combo faced a similar issue? Am I going to have to get rid of my Tokina? It's such a fun lens. I was really looking forward to using it with the Mark IV.
