Is the crop factor 5? As compared
to full frame still photography.

Almost 5.

 

The focal length multiplier from Super 8 (diagSuper8 [1:1.33] = 7 mm) to Full Frame 35 (diag24x36 = 43.3 mm) is actually x 6.19

 

Or x 0.16 the other way round.

Just compare the dimensions -- if you want to compare horizontal field of view, Super-8 is 5.79mm wide and Full-Frame is 36mm wide, so that's a 6.2X crop factor (36 ÷ 5.79).

Thanks. That explains why 7mm focal length doesn't seem that wide on S8

6mm would be the ideal wide angle for Super 8. The top production cameras by Beaulieu, Leitz, Bauer, and Nizo have that as the shortest focal length of their built-in or interchangeable vario lenses.

 

A 5mm prime, or indeed a 6mm or 7mm vario setting on any lens with the Schneider Kreuznach Superwide / Ultrawide Lens Type I/II/III or Type Nizo attached would get you down to 4.5mm - 5mm. But you would have to expect distortion in your shots that may be unacceptable if you don't look for that kind of aesthetic on purpose.

The Schneider UWL definitely does not fit/work with any lens. Oddly enough it mostly goes well with the Schneider zoom lenses :) Other types are better cross-checked before buying one.

Huh? Any lens with such a working wide angle lens attached will go from 6-7mm down to 4.5-5mm. The laws of optics are usually brand-agnostic  :rolleyes: . To pick the right working configuration is frankly self-evident, isn't it?
