The befuddlement in part comes from popular and erroneous terminology. The 15mm lens does not become a 21mm lens. Its angle of view is reduced on the smaller (compared with 35mm) sensor to about that of a 21mm lens on a 35mm film camera. The angle of view of the 15mm lens on the M8 matches that of the external viewfinder (originally for a 21mm lens on 35mm film) because the viewfinder isn't cropped. > so... can one also use the M8 viewfinder, as the viewfinder for a CV > 15mm lens...? No. The M8 viewfinder can be used for framing with the 21mm lens because the 21mm lens is cropped on the M8's sensor. > Why is this so difficult? Because the popular terminology is bogus.
