Paul,
I would love to see how Mamiya Glass performs on Your Kodak.I think the color would be even better than Zeiss glass.The colors that i get from my Mamiya glass is as good as the Zeiss colors maybe better but what i think makes the biggest difference is the smoothness of the tones.

Paul,
any of the Mamiya glass will give you great color.Probably one of their best lenses is the 120f4 Macro.If it was 2.8 it would be perfect.I am also starting to like the 35f3.5 this thing is tack sharp wide open and just gets ridiculous when stopped down.The 80f1.9 is the fastest MF glass available today.

Yes, that's why it goes to the Stupid stuff section. The 12.5mm Computar lens is a C-mount lens made for CCTV/Machine Vision. I don't know of any C-mount lens in that focal range covering the whole 4/3 sensor.
The image is cropped from 4:3 to 1:1 and the lens works fine for anyone fond of square images (I am, many of images end up 1:1 or close to it). The G1 is a 12MP camera so composing for square images leaves you with 9MP to play with. Well, it works.
The lens is surprisingly sharp. The bokeh is a bit so-so wide open but fine from f/2. There are only three aperture blades and you can see that in the upper right of the image above. Most often that doesn't matter (and it makes company with Rollei). Medium contrast, it doesn't like stray light.
An equivalent FF lens would be, assuming 1:1 format, a 23mm lens. DOF-wise it would be a 23/2 then. Well, it's not bad at all considering the price; USD 25 plus a converter for another USD 25 and then half an hour of work at the kitchen table making it fit the adapter.
