This is my new favorite lens, the pentax super multicoated (SMC) 35mm F3.5 lens. I tested it on full frame and micro four thirds (mft) and it produces sharp wide angle lenses on full frame and beautiful tighter images on m43. This lens is fantastic on my full frame sony and micro four-thirds G7. Some of the following product links are affiliate links for which I may be compensated.
