Finally.....Photozone reviews the Pany 12-35

You should tell this to Samyang (Walimex, Rokinon, etc.). I have their m4/3 fisheye and it is tack sharp across the frame even wide open and has no visible chromatic aberrations - all this with zero software correction as the camera does not even know the lens is there. Just an OPTICALLY excellent widest-possible lens and very cheap as well

For the kind of money Panasonic are charging for this lens of theirs, the inherent chromatic aberrations and the sharpness falloff at wide angle are a disgrace.
