The slow lens and fixed shutter speed almost necessitate the D3200 unless you have a ton of light. Looks pretty good in Xtol too...
Wasn't film a lot slower back when this was made (Zeiss Ikon Box Tengor 54/2, made from 1934-1938)? I couldn't imagine using this with 25 or 50 ISO film... You would have to use bulb for like every shot...lol.
Well, according to this http://photo.net/black-and-white-photo-film-processing-for in 1937, Ilford's fastest film was Hypersensitive Panchromatic (later, HP5), and it hasd an H&D rating of 2500. This was before the ASA system was adopted, and film sensitivity was often given in other systems; Hurter and Driffield; General Electric speed; Weston Speed, etc.. According to the author, dividing the H&D speed by 40 gives and approximate value for modern ASA/ISO speed, so Ilford's top B&W film speed would have been ISO 62.
So...it seems that the camera would be pretty well-suited for Sunny 16 with the equivalent of ASA 25 film. Your camera has an instantaneous speed of 1/25 second, plus B. And with its three f/stops of 11,16,and 22, that would be okay!
Hmm. There haven't really been many sunny days since I got it (about a month ago). Once the weather gets better I'll have to try that. It's dark by the time I get home from work, and the weekends haven't been very sunny...
Indoors with the blinds open, 1600ish seems to be working well though. I really wish they made Kentmere 400 in 120, lol. I really like that film in 35mm, and it pushes very well. Tri-X is probably the closest to it in 120, but I don't think I've ever tried pushing Tri-X past 1000, maybe 1600. It's been a while since I've shot it...
Another picture of it:
The lens has a self portrait mirror that moves out of the way as you're moving the shutter release.
