Why buy an expensive body and put cheap lenses on it? The lens takes the picture, not the body. Buy a cheap body and put expensive lenses on it, you'll get better pictures. I've seen this over and over. People buy a top end SLR body and put cheap consumer lenses on it; people buy a high end stereo receiver and hook up a cheap set of speakers and then wonder why it doesn't sound great.
I feel if you want to shoot Russian lenses, buy a Russian camera. I have nice FED 3b for my J-12 and J-9.
Just my 2 cents.
