This macro lens provides a normal perspective and allows for close focusing down to 1: 2. The Makro-Planar T 2/50 uses a new lens design which incorporates floating elements to ensure high performance across a wide focusing range. As a result, the lens can be used for non-macro applications and becomes a versatile 'standard' lens when used with a full frame camera. The fast f/2 aperture and distortion-free performance enables wide-open photography with a short depth-of-fi eld without compromising the image quality. The Makro-Planar T 2/50 is available with the F bayonet (ZF) and K bayonet (ZK) lens mounts and is designed for use with full-frame SLR and DSLR cameras. Combined with a DSLR with a 1.5 crop factor, the lens becomes a focal length of 75 mm.
