If assuming that you have a lens that is 21.875mm, which is 35mm after FLM, then you will achieve the same picture as using 7.8mm (which is 35mm equivalent) on your digicam. However, the bokeh will not be the same due to the physical size difference of the apperture (but the f number can be the same!!).
