Here are some sample shots from my favorite new street cam and one of my favorite M42 lens. The Industar 50/2 3.5 is probably one of the best-kept secrets among manual focus aficionados. The Industars are clones of the Zeiss Tessars and the stock lens for the Industar bodies produced in the Soviet Union. They are remarkably lightweight and sharp wide open. They are also some of the smallest lenses out there. If you want a pancake prime for cheap, you can't get much better than the Industar 50/2 3.5. Shipping from the Ukraine will probably cost just as much as the lens, but considering how popular manual focus has become with the release of micro 4/3 cameras, SONY NEXs, and almost everyone's try at mirrorless cams, costs are just going to go up in the years to come. I have a nice set of M42 Takumar primes that I bought for about $20 each including shipping. Nowadays on Ebay some of these are selling for between $50-100, and that's just for the lens. Heck, I think I'll probably order another Industar from the Ukraine as a back-up. They shoot great on Canons as well.
The GF3 processing engine tends to be pretty faithful in reproducing real world colors and is wonderful in not blowing out highlights.
