[QUOTE="dieselnutjob, post: 762098, member: 47318"] I completely dismantled the 180mm f2.8. I couldn't see anything in there that "adjustable" except for one thing, which is where the end stop of focus cam bottoms out. Essentially that would impact whether the lens can go beyond infinity and buy how much and whether it runs out of travel completely. Maybe I should have a play with that and see if it effects the fine AF or not. The other thing I have to try is whether it makes a difference if I go from infinity to my 2.5m calibration point, or whether I start closer and go out. [/QUOTE]
