Dear PF and Dirk, Thanks for your reply. I tried to reverse the rear group in the opposite direction but it makes no different. The attached is the rear group which is convex on both side. The one facing the front is move convex then the other side which is different from the schematic I found on the internet. The one towards the front is concave, instead. Dirk made a good point that it did not cover the full frame. Compared with the other Industar 61 I got, the image is much bigger. No. I don't have the thin ring. I will try to shim it to see whether it makes any different. Best Regards,  |
