My M2 has been hanging on a hook in my living room for months now, mostly I think because I'm tired of the lens on it, an old Nikkor-W 3.5cm which is nice but has just gotten boring. I'd like to find another lens for it, 2.8 or faster preferred. Voigtlander or other brands welcome. I really like 35mm but would also consider a 1.4 or 1.2 50mm. And of course, the kicker, I don't want to spend more than 400$.
