Originally posted by Clarissa Just found a black lentar telewide finder on accident, was wondering its value if I have no use, need to research models it works with. I only own one film camera, a Minolta X-370 s.
Tele-Wide finders typically sell for US$25 or less. Ironically, a loose finder is frequently priced higher than a finder WITH its pair of auxiliary lenses. The Lentar finder was sold in a set with two "auxillary lenses" (one tele, one wide, hence the "Tele-Wide" name). Auxiliary lenses screw onto the filter threads of a fixed-lens camera, giving the camera tele- or wide-angle capability. The camera's built-in viewfinder didn't show the actual view through the lens (these were basically point-and-shoot cameras), so the markings on the Tele-Wide finder would give an idea of what the view would be.
Most Tele-Wide finders are the generic type that slides into a hotshoe - some cameras without a hotshoe mounted the finder via a metal bracket - those finders are dedicated to a given camera model and pretty much useless today, except for DIY projects. The two Lentar sets that I found on eBay are generic types labeled by the filter ring size that the aux lenses fit on.
