What was the problem with your 28/2?
As I have said my lens has an unusual out of focus behaviour towards the edge of the frame. One obvious situation is when at infinity things far away is sharp at the centre but funny out of focus at the edge at f2. Can see clearly already in view finder. Then one day I was observing the photos of all the 28/2 on ebay. I realised that all of them has a deeper screw thread section (in front of the front element for filters) than mine. So I suspect the lens must have been open up by somebody and did not fix back the floating element properly. Luckily one technician here in Singapore willing to give it a try and it is fixed now. At f2 at infinity everything far away are equally sharp now.
Nearly need to post here see if anyone in HK can fix this. Email Zeiss Germany they replied not servicing this lens anymore.
