I am considering buying one of the tiny 35mm Ricoh compacts. I'm aware the 1V has a 28mm lens and the 21 a 21mm lens. Aside from the differences in aesthetics that the different lenses imply, does anyone here have any practical advice they can give me as to which to buy? I'm thinking of things such as: - The relative optical quality of the lenses; - Practical differences (I believe that one may require a lens cap? And the process for mounting filters differs?) Also does anyone know of websites where the two are compared (I'm aware of sites about the 1S and 1V but not the 21).
