The Wollensak 2 inch (50mm) f1.5 is such a gorgeous lens in typical chrome finish as many c-mount cine lenses are. It's a very hefty lens, which is much heavier than the Kodak 50mm f1.6 that I also love. Both the aperture and focusing rings work, thankfully. I couldn't wait so as soon as I got the package, I put it on my NEX-5N and snapped a few pictures. First thing I noticed was that flare will be a huge problem (like most c-mount cine lenses). Secondly, it's as sharp as the Kodak 50mm f1.6, but has a much larger imaging circle. There is visible vignetting, but the corners are much better than the Kodak. Consequently, the larger image circle makes the swirling effect less visible than the Kodak.
I have a feeling I will be using this lens quite a bit for the next little while.
