The Space Captor! Great name, I'll buy one on the name alone.
Good distortion, decent fall-off wide open, gets better at F8, what's not to like?
Oh, 58mm filter, at least that's the same as an early Noctilux (yeah, like Everyone's got one of those lying around, sheesh).
At least its not heavy. What about the hood? I see a bayonet fitting, looks like expensive hood solution to me.
