Mir 47M 2.5 / 20mm
Mir 47M 2.5/20mm bought (new) on eBay on june 4th, 2008 for 170$ +32$ sending fees.
This lens has an unusual look; the quality seems good, notably for the minimal barrel distorsion. There is no button for manual position, it can not be used on a Zenit E, except with a little modification.
Delivered in a leather case, with a set of 3 filters, to screw on the back.
