It's a Voigtlander Nokton 50mm f1.1 lens for the Leica M mount camera. I'm kind of a sucker for fast lenses, since I shoot in low light and hate to use flash. On the surface it gives you exactly what you would ask for - slightly more than an extra stop over an f2 lens. But it also gives you incredible bulk and weight on a camera system that's supposed to be light and nimble.
All of these images are shot on Kodak Tri-X 400 film pushed to 1600 ISO and developed at home in Kodak D-76 (stock solution) for 9.5 minutes. The Nokton allowed me to use a little faster shutter speed than an f2 or f1.4 lens, but not really enough to justify the extra bulk. Most of these images are fine.

Ultimately, here's why I decided to part with this lens. Sure, it's heavy and bulky, but I absolutely hated the distorted lights in the corners. I know it's a lot to ask of a lens not to give you these seagull looking lights in the corners, but I noticed these on two night time rolls with this lens.
There's a happy ending though, the Voigtlander got traded in for a 1982 Nikon FM2n SLR with a Nikon 50mm f1.4 lens. Pics from that coming soon.
