Not trying to edge in on Evin's territory, I just thought I'd post my own test image. I recently bought a Nikkor AI 50mm f1.4 MF lens. Now I'm a Canon guy, so I ordered an adapter to put it on my Canon 20d and did some tests. It's actually good practice, since it's a similar setup to Red.
So here's the result. The iris was at f5.6, camera was at ISO400 and 1/60 shutter. Dang, I love this lense!
