So i picked up this Gem from good old ebay once again. 8 bucks bought it, seen the same lens go for $99.00 - $60.00 on there after the fact that i bought it. It was listed as a Soligor Skrew mount, so i was thinkin m42, but at the price i bought it for i was willing to take a gamble. So i rolled the dice.... NOT a m42 mount! And hence why im posting this, rear cap for it is from a Minolta and fits like its natural, which i believe it is, never see this type of mount, says M/MD in small red letters in the outer ring, 5 small skrews, three top, two bottom, has a bayonette which opens the shutter instead of closing it... I feel like i made a mistake getting the MD-M4/3 adapter, on a hunch, so can i get a little help please. Thanks Gennady.
