With its normal perspective, fast maximum aperture, and high-end design, 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. On top of that, the legendary Zeiss T* anti-reflective coating combats flare and ghosting for crisp, clear imagery. Performance is top notch as well with speedy autofocus provided by a ring drive Super Sonic Wave Motor (SSM) system. An AF/MF switch is provided for quickly changing between the modes and an internal focus design maintains overall lens length during use. 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. An eleven-blade circular diaphragm further improves image quality by ensuring smooth bokeh at a wide range of aperture settings. Additionally, a dust and moisture-resistant construction will keep you working even in less than ideal environments.
