The Planar T* FE 50mm f/1.4 ZA Lens from Sony is easy to see as a go-to standard optic for full-frame E-mount shooters. Starting off with the fast f/1.4 maximum aperture, photographers and videographers will enjoy exceptional low-light performance along with the ability to create shallow depth-of-field effects. The Zeiss Planar optical design benefits users by providing an almost distortion-free image, while the incorporation of one Advanced Aspherical, one aspherical, and one extra-low dispersion element work to minimize spherical and chromatic aberrations.  A physical aperture ring is present on the lens which can be de-clicked at the flip of a switch, making this a great option for video in addition to stills. Based on the Zeiss Planar optical concept, this lens uses a design with 12 elements in 9 groups that helps achieve the large maximum aperture of f/1.4 while helping to minimize chromatic aberrations. Fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over the focus position when using shallow depth of field techniques. One Advanced Aspherical (AA) and one aspherical element are incorporated into the optical design for effective control over astigmatism, field curvature, coma, and other spherical aberrations. The physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
