Lighter than other 67 or 66 format wide ange lens.

None

Since the largest aperature is F4, there is a little bit dimmer at the viewfinder corners. Of course, such dim corners won't happen on the slide images.
The optical quality is good, very little distortion and hard to recognise.
The focus ring is moving smoothly.

-None. The best lens in the Pentax 6X7 line-up by far.

This is a gem of a lens. Enlargements produce life-like representations of a scene, you feel like you could enter the scene. High-definition and contrast, first-rate mechanical construction. It focuses to 30 cm, permitting even the photography of butterflies on flowers. I try to always shoot on a heavy Manfrotto tripod to fully exploit its potential.

All but one of the pictures I've taken with my P67 and had blown up beyond contact sheet are taken with this lens. It may be me, it may be the lens. Who cares?

Like anything to do with the P67, it weighs more than you wish to imagine

Sharp, heavy, with a very nice "out of focus" behavior, as well.
