I had the MIR MC 47K 20 mm. 2.5 some years ago. It is a metal made lens, in fact it is very heavy and bulky. It doesn't have a front thread for filters, though. You have to screw the filters at the back of the lens, the lens includes four of them. It is sharp, except wide open were it is good at the centre but soft at the corners. It is multicoated, and it is quite resistant to flare, although it isn't in the same league as SMC Pentax lenses. These lens has a "hot" colour rendition as it is usual in Russian lenses, at least the ones I have used. In the early examples of this lens, when you screw a filter it can interfere with the movement of the mirror in some film camera bodies, I have read that it doesn't happen in the recent batches of this lens. It doesn't interfere with the mirror in the DSLR bodies because being APS-C digital format bodies, their mirrors are smaller. I paid 100 USD for that lens when I bought it new in 2002.
