I would like to trade my Olympus OM gear for your CZ Sonnar T* 85/2.8 lens.
I offer the following:
OM-1n in excellent condition, the only flaw is 3 light scratches on the bottom plate.
OM-2 in good condition. The aperture ring turns stiff, but rotates to all f stop settings. The cover material is getting loose on the front right side, and there is some wear and light scratches in the bottom plate paint.
OM 28mm f2.8 in excellent condition. The glass is clean & clear, aperture & focus trun smooth, a very nice lens.
Here is a link to some pictures.
If you are interested please send a PM and we can haggle.
