very good at Panasonic pancake Objekti

Panasonic Lumix GH2 + Panasonic H-H020E Pancake lens Lumix G F1.7 / 20 mm (40 mm KB, 46 mm filter thread) + Filter Adapter from 46 to 52mm.

I believe we should no vignetting effects, despite the slight wide angle. Both in the video mode, and in the "native" 4: 3 photo mode of camera.

A star deduction is available for the not 100% good workmanship. I see a couple of small degrees of unevenness and the gum. But these things are really just aesthetic error and do not affect the lens hood in their function.

Very nice, I think that you can "fold" the lens hood to about 1cm thick. This saves space during transport.
