I have a lovely Schneider Tele-Xenar 180mm f/5.5 that doesn't see much use anymore. It is a 2x3 lens, but I used it mostly for close-up pix using my Speed Graphic, so it covered fine. Made beautiful and sharp 4x5 transparencies. I was surprised at first because it is a 2x3 lens, a tele, and at such high magnification I expected usable images but not horribly sharp ones. Sometimes I would use it with an RH-10 back, and once on a Polaroid pack film back to make transfers onto watercolor paper. The fact that it is a tele helped a lot with the limited bellows of the Speed. I got it on a Graflex Press board, and there it remains. I haven't shot the Speed at all in studio since getting my Sinar, so haven't used the lens since. Maybe I will get around to putting it on a Sinar board some day.
