I have the original version in Alpha mount.

To get the best of this lens on a full frame camera, it is necessary to use a small aperture. F/11 seems to be the best tradeoff (diffraction soften the pictures with higher numbers, at F/8 and below, the corners tend to be softer).

In practice, this isn't a major constraint, and this unique lens has some redeeming features (cost, weight, very low distortion, etc.)
