 I just checked play by checking movement of the lens on camera.......the animal process!  :o

 

 However, with a heavy tele, be it the Nikon or the Tamron, any sort of "movement" when clambering around in the wild, play becomes immediately apparent, the V1 Tammy had the tiniest bit in the lens-hood, it was so slight, but you felt it, very annoying!

 

  I think you have been a little unlucky there JoJu.........don't Rolex make F mount adapters?
