Jupiter 21 4.0 / 200mm

Jupiter 21M 4.0/200mm, bought for 600F on july 27, 1994.

I got this lens new, with its leather case; no filter.

I spent a very long time looking for the Telemar 22 (5.6 /200 mm) on my list.During this time I found this nice lens, more recent than Telemar. Almost good. I had better find a Jupiter 21A than this 21M, it's the same one,with interchangeable "A" mount(so using no diaphragm-coupling).

Jupiter 21A 4.0/200mm, bought for 24£ on eBay on august, 29th, 2007.

As I only found the "M" model, I was wondering if this lens had ever been marketed. Then I found this one on eBay, and won the auction for a very reasonable price. It looks used, and there is a little mark on the front lens, but now, I know it exists!
It looks thinner than the "M" model (no coupling mechanism for the diaphragm).
