As a photographer you need in addition to religious union cameras of course, the perfect match to end lenses. As previous speakers have already written; that is the objective quality as I know and love from Nikon. I use the Obtik which are screwed on to a D3x that really everything demanded of the lens with its 24.5 megapixel sensor. A unique focus gives this trailer, which can be exceeded or only of medium format cameras reached in my opinion. The focal length is perfect to take pictures for studio use for portraits and the like. Consistently 2.8 maximum aperture whatever the focal length and focusing. Even with Aperture 2.8 recognizes only a very practiced eye vignetting. The lens is extremely high and the AF flash. Wonderful product, I would not hesitate to re-buy Absolute buy recommendation.
