When using on digital SLR (e.g. Minolta 5D, 7D und Sony Alpha 100, 200, 230, 290, 300, 330, 350, 380, 390, 450, 500, 550, 700) a SUPERTELE with an equivalent focal distance of 136mm results due to the extension of the focal distance by 1.6!
The walimex pro 85/1.4 IF Lens is a classical portrait focal distance, which enlarges the creative photographic scope. It has a focal distance of 85mm, a speed of 1.4 and an mechanical aperture ring. The Objective is optimised for medium and large distances. It provides a very high and orthoscopic imaging performance, which is still increasable through stopping down.
Due to its high speed, the walimex pro Objective allows the usage of shorter shutter speeds or lower light sensitivity. This feature reduces the interferences at digital cameras.
Even at a high speed, the walimex pro Objective provides shorter shutter speed. The Objective can reduce the noise at digital cameras. For example, it facilitates the cropping of motifs in front of unsharp front or backgrounds in moderate wide angle and tele range.
For single lens reflex cameras, the high speed benefits the brightness of the viewfinder and facilitates the focusing. The higher focal aperture with lower field depth optimizes the position of the focus level in the viewfinder. Therewith, the focus course can be rated more exactly. The lens possesses an inner focusing.
The Lens possesses an inner focusing. This is a technique, in which not all needs to be adjusted for focusing, but just one or few lens groups inside the lens. The filter thread will not move when focusing the lens and the center keeps almost the same.
The aperture is build of 8 diaphragm blades, which allow a very impressive depth of field. All lenses are covered with anti-reflecting coat and the light transmission is on a very high level.
