I'm wondering if anyone has done a side by side comparison of these two lenses, and if so, which is sharper and has the better micro-contrast, rendition, etc. From reading this forum, I've formed the opinion that the HR is probably optically a bit better, but that's just an impression from what I've read.
The Schneider is about $100 less than the Rodenstock here in the USA, so not a big difference in price (considering they're both over $5K USD). The Schneider has the edge in image circle, but the HR is an f/4 lens, vs the f/5.6 Schneider, so it should be better for ground glass viewing.
I'm probably not interested in using such a lens with rise or fall, so the image circle probably isn't a big deal. Sharpness is a big deal for me, however.
