The only reason I can see for keeping the slower 135's is that they are so much more compact and weigh considerably less. With the Canon adapter ring and a UV filter the Porst 135 f1.8 gets very close to 2lbs.

The beast has arrived from Germany. Absolutely lovely condition - a really beautiful lens.
The halation is less pronounced than most of my fast lenses wide open - a surprise. The only obvious things were as you say, a slight drop off in sharpness, and I have noticed a touch of vignetting. Agree, extremely usable wide open, and it beats the crap out of my other 135's at f/2.8.
This is going to get more use than I thought, especially as a still lens. It is pretty cool to be able to occupy the frame with a sharp, well exposed image a of a face in low light from 10-15 feet away. It really creates an intimate shot because of the shallow DOF and the fact that the distance of the camera is not a threat to the subject.
Just so you know Joel, I would never have know there was an affordable 135 f/1.8 out there, had I not your read the post you made when you got your Porst, a name I hadn't heard of. Keep sharing the knowledge!
