One of my earliest serious 3-D printing projects, this lens was originally pulled from a digital projector. It was a really tight squeeze to get the lens mounted with the proper flange to focus distance, but it was doable. As it turns out, the Up! Mini and associated plastic produce an F-Mount strong enough to support a light film or digital SLR hanging from the back, though I wouldn't jump up and down with it if I were me. The lens might be able to produce an image circle compatible with medium format film/sensors, but I don't think the backfocus distance is long enough for it to play nice with my Hasselblad. Further complicating that possibility, the lens does not have an internal shutter, rendering it currently useless with anything but long exposure.
