An additional fixed diopter viewfinder lens will not solve camera rangefinder focusing problem, except at one specific subject distance. What helps me is my eyeglasses with variable diopters, I guess tri-focals or bifocals would help too, although to a lesser extent. The little screw-on viewfinder lens is of no value to me. >Chris > >-- >To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html - -- Christer Almqvist D 20255 Hamburg and / or F 50590 Regnéville sur Mer - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
