Dreamer, with many 120 film box and basic folding cameras available for the patient buyer, trying to make do with any other size seems wasteful. The larger bellows cameras came in quite a variety of film sizes, which can really be a hassle. A bargain large camera may be quite expensive by the time one is able to use it. Do lots of homework before investing in one. Junk and especially antique stores often place an inflated value on cameras that may be 100 years old.

Box cameras with three apertures are usually about f/16, f/22 and f/32, although this varies from camera to camera. The shutter speed of the one I just examined is about 1/40 or 1/50 second. This also varies from camera to camera. A few have cemented doublets instead of a simple meniscus lens for slightly improved performance. Box cameras with the lens in front of the shutter sacrifice performance for compactness. At the smallest apertures box cameras are decent performers, but rarely as good as the original owners boasted.
