I unexpected got the chance to bid an Schneider Xenotar 150mm the other week. A bit beaten up with some damages to the coatings and a scratch on the from element but otherwise in good shape.
To my surprise I got it for a more than fair price.
This being a truly large format only experience with a 35mm millimeter equivalent aperture of 0.8 (theoretically, but more on that further on, since the shutter will change that a bit) , and with a reputation of being super sharp I was somewhat thrilled.
Got the first four test shots back from the lab the other day, and thought I would share. It is a special lens.
There might be someone interested, at least I would be.
First, it came mounted in a barrel, so I re-mounted it in a Compur 2-/5/II that I took from a Symmar 240mm.
Doing this actually change the maximum aperture to 3.0 (as far as I could measure(. It's still very impressive but something you should aware of if you get one. To get the full 2.8 you would need a larger shutter I think, but I don't know if it ever came configured for that. In old catalogues it's listed with a Compur 2-/5/II .
Here are four test shots. To motives taken fully open at f/3.0 and at f/5.6.
All shot on my Chamonix 45H-1 with Ricoh RPX25 and scanned with a Flextight Precision III.
I've set the white and black point and some curves and contrast, but added no sharpening or clarity.

f/3.0
I focused on the chain on the wall

f/5.6

f/3.0
https://scatteredlightblog.files.wordpress.com/2020/06/sheet0122.jpg
f/5.6
My own first thoughts are:
- Wide open it's very sharp in the center, but with a lot of spherical aberration, and with lower contrast at the edges. There is still a lot of detail. A lot of glowing character that you can either love or hate.
- Focus plane and depth of field is super thin. This will be a problem for portraits, where even a small motion forwards or backwards will ruin the shot (we are talking millimeters here)
- Bokeh is rather nervous wide open but becomes better stopped down.
- Stopped down it is very, very sharp al over. I love how it renders the statue att 5.6 with every scratch and mark visible.
This is definitely a specialist lens.
I'm a little bit disappointed with the bokeh rendering, being a bit nervous and not that smooth, at least wide open.
I will try a few portraits and see what happens.
