Hello,

I revive this thread, because I see that a detail was missed, about the MIR 20M.

Let's not forget that the three filters are part of the optical scheme of the lens so, one of them should always be mounted to the rear, threaded mount.

Using colour films, the "UF-1x"; with B/W, the "O-2,8x" or the "ZHZ-2x" (orange-yellow and yellow-green) resp.

Missing this detail, the quality of the lens decreases drastically, thus the reason of negative opinions on this wideangle.

In the practical use, I've found this lens of great quality. I've purchased it in the past september, in like-new condition; its serial no. is 842848, complete with metal-fitted leather case, with lens's name embossed on the lid, this, with compartment containing the mentioned filters.

The lens itself is superbly finished.

Best wishes,

Enzo

How is this lens different from, say, 16mm Zenitar, which gets better performance by removing rear filter & readjusting focus? Thanks.
