This review is from: Opteka 500mm f/8 Telephoto Mirror Lens for Nikon D3000, D3100, D3200, D5000, D5100, D5200, D7000, D7100, D3, D4, D40, D40x, D50, D60, D70, D70s, D80, D90, D100, D200, D300, D600, D700 & D800 DSLR Cameras (Electronics)
is a very good qualitylens; the material is good. the extension adjusts easily, smoothly and is very sensitive. obviously such optics requires lots of practice and focusing is really tiring. the lens is provided with an adapter, three filters and the soft case.
