Pentax hd fa 43mm f 1 9 limited vs sigma 35mm f 1 4 dg hsm art?

The Sigma 35mm f/1.4 DG HSM Art is my pick for most people. It's a 35mm that works on full frame, it comes in Canon EF, Nikon F, Pentax K, Sony E and L-Mount, and it's common and cheap used. That makes it the safer buy if you might change systems.

The Pentax HD FA 43mm f/1.9 Limited only fits Pentax K. On full frame its 43mm view is a little tighter than the Sigma's 35mm, so it suits you if you already shoot Pentax K and like that slightly closer look.

Your sensor decides how each lens frames, so check the sensor sizes before you buy. For a first fast prime, the lenses guide explains where either one fits.
