Yeah, very nice indeed! I'm really enjoying the Switar 25/1.4 I have mounted almost permanently on my GF1, and even enjoy a *bit* of the light fallout and distortion at the corners, but it'd sure be nice if I could actually get a sharp image corner to corner when I stop down (rather than the vignetting becoming more obvious Smile

Thanks guys! The Switars certainly are great lenses too!

Great lens and wonderful shots!! I've got a 50/1.8 Cosmicar that I need to get my machinist friend to turn down the mount to get infinity focus. What's neat is that it has a triangular iris. I remember reading in the Zeiss Compendium that there was either a standard lens or portrait lens made with a three bladed iris as well. Looking forward to seeing the bokeh on that lens.

Great results, Klaus, better than I have achieved so far...

I'm pretty sure you are referring to the 85mm f/1.4 Planar for the Contarex system, which indeed had a 3-bladed iris.

Thanks Peter, I have it a little longer I guess .... you'll beat me easily in normal photography from what I have seen so far Wink Wink

Kinoptik 2/25mm has 6 blades:

Very nice. I always thought this lens was larger, maybe I mix that up with the Arri version. I really like the pink explosion shot.
