I had an A 50/1.7 behaving that way some years back. I have also had an A 24/2.8 that developed the same problem after cleaning and reassembling. With the 24, the fault was that a small piece insided the bayonet had slid out of position. My own fault for being tired when I reassebled it after cleaning. Removing the bayonet and adjusting the fiddly bits solved the problem.
The 50mm was sold to an LX user who didn't mind...:-) I don't know if the A*200/4 macro is particularly prone to it; my specimen had behaved nicely for two years since I bought it.
