I don't want to start a war or anything I just wanted to post some of my feelings. I will write a very focused review about Schneider and Rodenstock lenses.
I just came back today from snapping a few very quick test images with both the Schneider 43 and Rodenstock 40. While in a lot of aspects the Schneider lens might be the better choice for the P65 and so on, I'm not so sure about the IQ180. I don't want to scare people, but that is just my early feeling.
I mean the Schneider is a lot smaller, is cheaper, has less distortion and is a great lens. However the color cast was very stong. (As can be seen in Guy's post somewhere here) Sure LCC works, but right now not perfectly. The finished files looks quite nice, but there is still to much red in the corners.
I will come back to this topic after more testing and reviewing. Sorry could take a little, I'm quite busy preparing for a trip in June.
