The Pentax SMC 50mm f1.4 has been on my radar ever since I fell in love with its brother - the Pentax SMC 50 f1.7 - A super fast yet affordable vintage prime with a vintagy cinematic quality to it and delicious bokeh with tons of character.

This is how you modify Pentax K mount lenses to fit on a full frame DSLR and Speed booster. It all comes down to grabbing a pair of pliers and just have at it.
