This bright and compact standard lens has a precise manual focusing mechanism and large rotation angle for precise control. The Planar T* 1,4/50 is designed for medium and longer distances and provides high-performance wide open, which only improves as the lens is stopped down. The lens construction controls flare and ghosting artifacts, resulting in a brilliant image with excellent contrast and natural color rendition. The Planar T* 1,4/50 is available with the F bayonet (ZF.2), K bayonet (ZK), EF bayonet (ZE) and M42 (ZS) 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 compact, lightweight 75 mm portrait lens.
