Lenses that swirl I saw two shots taken with a Summitar 50mm f2 lens that show a swirly background (though not as extreme as some LF lenses). Are there other 35mm format lenses that swirl (obviously, under certain circumstances) and that can be found at a reasonable price. To me a reasonable price will be less than $200 U.S? I'm particularly interested in an LTM lens. If no such lenses exist, are there SLR lenses that have this property? I'm aware there are LF lenses that swirl, but at the moment I don't have any interest in hauling around my 4x5 Cambo to take an occasional swirly shot. These are the Summitar shots I'm talking about: Flickr user:tetsuya miyoshi Flickr user:Marc-A Thanks.
