According to Pentax/Samsung Rumors:
The SCHNEIDER lenses wont be m42, they´ll be new design.I wrote in another thread that the ability to use MF legacy lenses would determine whether or not I buy an NX10. Assuming that these new lenses are good (and why wouldn't they be?), the NX10's alleged inability to allow easy focusing of MF lenses is suddenly no longer a deal breaker.
The SX lenses (SCHNEIDER-SAMSUNG) be 4 this year and 2 next year.
-15mm f/2.3 Super-Angulon
-21mm f/2 Super-Angulon
-35mm f/1.4 Xenon
-55mm f/1.4 Xenon
-90mm f/1.8 Tele-Xenar
-70mm f/2.8 Claron (Macro)
Lenses with AF/MF switch and mechanical focus.
Great that Samsung has a much better understanding than Olympus and Panasonic of the importance -- to some of us, at least -- of fast prime lenses.
