But Leica took this route, Henry and I can only think its because they felt like they had a line on a simple glass formula which would give superb results comparable with extensions but with no loss of light. Nikon makes one of these multi element front of lens magnifiers for their tele lenses as well at 5 price points I'm sure lower. But it has a very good reputation in a different league from the single element ones. I can only think the Elpro a pristine piece of glass placing even my Zeiss Proxars in it's shadow. That's what I'd think! Mark Rabiner Portland, Oregon USA http://www.markrabiner.com - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
