The Zeiss Makro-Planar T* 50mm f/2 ZF.2 Lens is a macro lens that provides a normal perspective and allows for close focusing down to 1:2. It 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 new ZF.2 lenses are an enhanced version of ZF lenses. They feature an electronic interface (CPU) that enables support of all important camera operating modes such as shutter priority, aperture priority and programmed auto exposure or manual exposure settings on non-AI compatible camera housings.
