This article in one of the fall of 1955 issues of Popular Mechanics magazine is a puff piece for Bushnell binoculars.<\/p>\n<p>The article notes how the binoculars can be attached to a camera as a telephoto lens creating a &#8216;560mm&#8217; equivalent lens. The article states that &#8220;ordinary binoculars cannot be used because of their low relative-light efficiency&#8221;.<\/p>\n<p>I imagine the low efficiency comes from older or cheaper binoculars without coated lenses. Around the same year 7&#215;50 coated lenses binoculars made in a small German factory were attached to a Minox camera with an adapter and worked quite well.<\/p>\n<p>Regardless of the promotion of the Bushnell brand, the idea of using binoculars as a telephoto lens via an adapter was a terrific idea back in the days of \u00a0prime lenses and film. It was a wonderful alternate use for binoculars.<\/p>\n<p>My thanks to my good friend George Dunbar for spotting and sharing this article. PS: I still have my 7&#215;50 binoculars but the Minox is long gone, swapped for a screw mount Leica.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Toronto.
