By the way, for anyone interested, I made a homemade adapter that allows Sony A-Mount lenses to be adapted to the Atik Infinity. I am using the Rokinon/Samyang lenses and they are far better than any M42 lenses I have tried. I have the 14mm f2.8, 24mm F1.4 and 85mm f1.4. They work great for wider angle lenses.
