I was wondering if anyone here had experience with faster mirror lenses. I saw a lens that tickled my fancy and budget, a 300mm f4.5, and I've been thinking about picking it up.
www.rugift.com/photocameras/rubinar_300_lens.htm I'd be primarily using it for baseball, for which I've been stealing Dave Brooks' Sigma 300mm f4. Speed-wise I've been shooting f5.6-ish anyways, so the fixed aperture is not an issue. Part of my interest is the size/weight factor; another part is the desire to differentiate my work. Aside from the donuts, what are the usual characteristics of a mirror lens? I probably shouldn't buy it. If I buy it and hate it, are there any Toronto PDMLers who'd want to buy a slightly used 300mm f4.5 for 90% of the price listed at that link? Alternately, is anyone out there looking to sell some longer, faster glass? -Aaron
