Are the 15/3.5 SMC-Takumars actually availible now and then?
Very hard to come by...
I've seen a Sigma 18/3.2 listed in M42 mount, but I'm reluctant to commit money to a lens that may not have an A/M lever and probably has old Sigma "quality" as well.

The one I have does have an A/M lever and performs well after around f/8 but flares badly.
