I wish to report successful use of American-made Kodak Ektra Rangefinder lenses on my Sony 7R digital camera body(full frame). Utilising a custom-made British adapter i am having fun mounting my 35mm f3.3, 50mm f1.9, 90mm f3.5, and 135mm f3.8 Kodak Ektar lenses on my Sony camera body. It is gratifying to put these premium-grade internally coated lenses, made to the highest optical standard more than 70 years ago, back to work. They were originally fitted to the best American-made rangefinder camera system, designed to be a credible competitor to the German-made Leica and Contax rangefinder cameras of the time. The results have been quite satisfactory and enjoyable to view.
