Hi Folks.
Just picked up a nearly pristine SMC Pentax 15mm f/3.5 that appears to be the rarer aspherical version, based on the info here:
http://kmp.bdimitrov.de/lenses/primes/ultra-wide/K15f3.5-i.html. I was looking for a user ultra-wide for A7r, but this seems rare enough that I might be better to sell it to a Pentax devotee and get something more utilitarian. Contact me if interested.
