I'm trying really really hard to like this lens but somehow I don't think it's going to work out.
I've had this lens on a few outings already and I keep coming back to the same conclusion. It's not up there with some other lenses, namely the Leica Heliar 75 f2.5 and the Minolta Rokkor 90 F4 and the Leica Elmarit 90 f2.8. Those lenses are really top of the line and produce great images.
I think this one is going on the to sell list.
I'll be posting some more images from this lens for the next few days so you can determine for yourselves the quality that can be expected from this lens.
