28mm.

I'm excited by the results of a quick bokeh test of the old Pentax SMC-M 28mm f2.8 and looking forward to more pictures over the coming weeks as I swap back and forth between the 28mm and 50mm lenses.

Ps. The EXIF data is going to be incorrect while i'm using the one K 2 EOS adapter (intended to go with the 50mm) to swap between lenses until I receive the second adapter pre-programmed to show 28mm ;O)
