The 500mm f/6.3 LD UNC AL Lens from Oshiro is a classic all-metal refractor-style super telephoto T-mount lens, with an aperture diaphragm in the middle of the lens body to stop down the aperture when necessary. However, it is assumed that much of the shooting with such a lens will be at its maximum f/6.3 aperture, with a tripod, monopod, or other such support. It maximum aperture of f/6.3 provides substantial light gathering for edge to edge sharpness and lovely high resolution photography. The included 2x doubler converts this 500mm lens into 1000mm.
When combined with the included T-mount to fit your Nikon F camera system (included), this super telephoto works on both "full frame" as well as "APS-C" style digital SLR cameras. You can use the lens in "M" manual exposure mode or "A" aperture-priority mode only. This lens sophisticated achromatic refractor design yields images with pleasing peak contrast and well controlled flare.
One extra-low dispersion (LD) element is incorporated within the design that helps to greatly reduce chromatic aberrations for increased clarity, sharpness and color accuracy when photographing in strong lighting conditions. Ultra nano multi-coating eliminates lens element reflections and reduces ghost and flare.
