And as a comparison two other small lenses I had in my bag:
Leitz Summicron CL 40/2.0 at f/2.0:
Leitz Summicron CL 40/2.0 at f/5.6
Schneider Kreuznach Xenoplan 28/2.0 at f/2.0:
Schneider Kreuznach Xenoplan 28/2.0 at f/5.6:
Clearly not intended for full frame cameras, but a remarkably large image circle. |

Thanks. There are also a 30mm lens, a 40mm f/1.9 and a 50mm f/1.9 - not sure what size the image circle of those lenses are. I used to have a rare 110mm and a relatively large 150/4 tele-xenar, but in a fit of reason I sold those as I hardly ever used those. At the moment I'm also selling a copy of the 90mm and a 100mm. I bought a few of these on a camera show and I'm slowly realizing that having multiple copies of the same lens is excessive.. |

Hi dickb, finding information on these lenses online is very difficult. Don't suppose you could let me know the length and weight of both the 90mm f/3.5 and 100mm f/2.8 Tele-Xenars? |

Sure. My versions are the Robot Royal (31mm interrupted screw) versions designed for the Traffipax system of traffic cameras. They may differ a few grams from the Robot Star 26mm screw variants
Schneider Xenar 45mm f/2.8 Dimensions: 47 mm x 35 mm Weight: 122 g
Schneider Tele Xenar 75mm f/3.8 Dimensions: 47 mm x 48 mm Weight: 141 g
Schneider Tele Xenar 90mm f/3.8 Dimensions: 48 mm x 52 mm Weight: 141 g
Schneider Tele Xenar 100mm f/2.8 Dimensions: 74 mm x 53 mm Weight: 336 g
Schneider Tele Xenar 150mm f/4.0 Dimensions: 103 mm x 45 mm Weight: 255 g
If you are wondering why I have these data formatted this way, I have been selling a few of these on eBay. I'll likely list some of these again soon.
I have had RafCamera make me some adapters for Robot Royal to M39 or more precisely LTM. I use these on a helicoid Leica M - Sony E adapter, with a LTM Leica M adapter. The helicoid makes it a nice compact close focussing combination.
I should have a 37.5mm 2.8 somewhere around here as well, and a rare 110 f/4.5, I'll list their dimensions in a later post. |
