Nice! Any problem with stray light with this kind of lens?I've heard nothing but good things about that one. Jim Kasson (who hangs out at DPReview's medium format forum) has one and has been showcasing what it can do in his IR photography.
That Roddie lens is definitely not in my budget! But I do like that focal length. Until I can put together the funds for a lens in that league, I've been pleased with my poor man's substitute: https://drive.google.com/file/d/1ydQw6aff8zArbeexV5XN9qtVGAi1Fn3r/view?usp=sharing This is 20mm left-right shift. Focus is 4.3km in the distance. It's for evaluation purposes so I exposed to the right and have done no processing.
