I got Mir47k and used it for a year or so. It was quite sharp (BW enlarged to 30x40cm), but I used it stopped to at least f8. It is big and heavy, metal construction. It has coatings, but the direct light caused some flare sometimes at one side (I could see it in viewfinder). I could not use original filters, because they would block the mirror on my MZ-6. The lens has no front filter thread, but good point is that the Cokin P holder fits perfectly. I had no problems with colors. I used it also with *ist D - it was very good for the money ($90), but I sold it few days after I got DA 16-45.
