>>4104214Daily reminder that "crop factor" equivalence
a. Can be used to find effective aperture as well as focal length
b. Applies to sensor/film sizes larger than full frame
So if you see a Fujinon 210mm f/5.6 lens for 8x10 large format, you can expect it to behave similar to a 28mm f/0.75 on full frame.
So yes, a wide angle lens with very wide aperture would get you the same effect.
