FA Robot Royal 75mm and 90mm f/3.8, Schneider Xenoplan 28mm

[dickb]

For those who appreciate German glass, I've got a few Schneider lenses for auction and a Rodenstock:


Robot Royal Tele-Xenar 75mm f/3.8 Schneider Kreuznach

Click here to see on Ebay

These two Robot Royal mount Tele Xenar lenses are very sharp and have an image circle large enough for full frame, I use them on my Sony A7











A Robot Royal Tele-Xenar 90mm f/3.8 Schneider Kreuznach

A Schneider Xenoplan 23mm f/1.4 C-mount lens

This machine vision lens has a small image circle, nowhere near large enough for full frame or APS-C, but when reversed I use it on my Sony A7 again





Frost on my window, magnification around 4:1.



A Schneider Xenoplan 28mm f/2.0 C-mount lens

This one has a much larger image circle, large enough for APS-C









A Qioptiq XR Heligon 100mm f/1.5 adapted to M42 also sold as Linos and Rodenstock

This lens has an M42 mount now, but it doesn't have a focus mechanism and infinity focus isn't possible on my Sony A7. For those who want to experiment with a very large aperture lens, originally intended for photographing X Ray screens
