A good tools To Every Photographer’s Arsenal Note: This is a Manual focus lens, without auto focus. You can use the lens in "M" manual exposure mode or "A" aperture-priority mode only. The Super 500mm / 1000mm f/8 Manual Focus Lens is a classic refractor-style T-mount lens, with an aperture diaphragm in the middle of the lens body to stop down the aperture when necessary.
