The optics comprise of four lens elements arranged in four groups with anti-reflective coatings that have been used to ensure high light transmission. This telephoto lens works with any digital SLR camera or film camera. You need to purchase a T2 mount corresponding to the make of your camera to use it.
The depth of field scale has been marked on the strong metal casing to facilitate shooting.
Its classic refractor-style design, with an aperture diaphragm in the middle of the lens body lets you stop down the aperture when necessary. This lens should always be used on a tripod or monopod and for that purpose a tripod socket is built-in to the underside of the lens.
