I'm very disappointed however, that there's play in the focus ring while in manual focus mode. It's so annoying I've given up manual focussing with this lens.
Up till now I've tested four samples of this lens (including my own) and ALL exhibit play in the focus ring. I contacted Zeiss Germany regarding this, and according to them, up to 1mm of play in the focus ring in this lens is normal. Well, I currently own fourteen AF lenses from various manufacturers, of which 8 disengage their focus rings while in AF (ie their focus rings don't rotate in AF mode), 6 of these do NOT have any play in their focus rings while in MF.
Yes, apart from the 135/1.8ZA I have one other lens that exhibits similar play in the focus ring, and that's the 85/1.4ZA!
