Going to give a Sony A7 II a try, so selling some M gear to pay for some recent purchases.
The Canon 100mm F2 Serenar is in beautiful condition and comes complete with front & rear caps and its original black case. Focus has been spot-on with my M-240 and M9-P. Glass is clean and I do not see any cleaning marks, scratches or signs of fungus. The lens is sharp at F2. This is a fairly high serial number, so it was made towards the end of the production run.
