Bjørn's Rørslett's Overview:

This lens replaced the older 55/1.2 and besides being neater and lighter, also offered a much better performance even at wide apertures. There is an endearing slight softness (bokeh) when the lens is deployed on a D1/D2-series camera and shot wide open, but the image even at f/1.2 has plenty of detail. Stopped down in the range f/2.8-f/5.6, image contrast is enhanced, sharpness is very good to excellent, and veiling flare has gone entirely. Quality deteriorates rapidly as expected with the lens stopped down beyond f/8. I suspect the corners at wide settings would be soft with this lens mounted on a 35 mm film-based camera, but haven't tested this so far.

The 50/1.2 is less troubled by hight-contrast and against-the-light shooting than many of its brethren, and the propensity to flare is kept well under control. Occasionally you can get a greenish ghost spot when the sun is placed towards the frame corners, though.

Image contrast even at f/1.2 is higher on the D3, so pictures come across crisper and appearing sharper with this camera. Focusing the lens on a D3 was easy.

IR: The performance is troubled by a strong tendency for a central hot-spot on several cameras, but not on the S3Pro UVIR (?). Strange.
