Setting the standard as Sony's flagship normal lens for full-frame A-mount cameras, the Planar T* 50mm f/1.4 ZA SSM Lens delivers outstanding image quality along with excellent handling and performance. Using a Planar design, this lens is able to offer a fast maximum aperture of f/1.4 for shallow depth of field, while two aspherical elements and Zeiss' T* coating ensure contrasty, aberration-free imagery. It also features an SSM AF system for fast, quiet focusing and has a focus hold button for more tactile control over operation. The 50mm's lens barrel is of the highest quality as well, sporting dust and moisture resistance while a nine-blade circular diaphragm helps users capture images with smooth bokeh.
