About Sony 50mm F1.4

A great camera starts with a great lens and Sony has collaborated with Carl Zeiss to create a series of high-quality interchangeable lenses for digital SLT and NEX cameras. Precision lenses by Carl Zeiss are prized by serious photographers and film-makers around the world and the company's precision optical instruments have helped document some of the most iconic moments in human history and ensure for the best in image quality.

The luxurious new optical design features 8 elements in 5 groups, with two aspherical elements for ultimate performance despite being a standard 50mm lens. The design is extremely effective at correcting various aberrations and realizes flat reproduction characteristics (minimal field curvature) befitting the renowned "Planar" name. Moreover, the combination of a rear-focus system and aspheric surfaces achieves high contrast from infinity to close distances for clear, sharp images even when the aperture is wide open.

With its 9-blade circular aperture, a design said to produce the most beautiful bokeh, this lens realizes beautiful defocusing unique to Sony and meets the stringent demands of advanced class users who are serious about photographic expression. The SteadyShot INSIDE image stabilization system built into Sony A-mount cameras provides image stabilization without affecting image quality, an advantage that supports the high depiction performance of top-class lenses.

Sony 50mm F1.4 Features

  • Quiet and smooth AF: Autofocusing is smooth and quiet, courtesy of a Super Sonic wave Motor. Excellent focusing performance includes a focus hold button, a focus ring that doesn't rotate during AF operation, a Direct Manual Focus function, and a rear-focus system that maintains the same length during autofocusing.
  • Dust and drip resistant design: The main drive unit is sealed with rubber packing, etc., to realize ample dust and drip resistance as a system when mounted on a camera to withstand tough usage in harsh environments.
  • High-grade metal body: The high-grade lens body is constructed of aluminum that offers both high rigidity and an attractive finish that contributes to pride of ownership.
  • Carl Zeiss Planar Lens: The Carl Zeiss Planar lens first became synonymous with high-performance lenses by realizing a large aperture, flat reproduction characteristics, and the successful removal of astigmatism.
  • Carl Zeiss T* Coating: Coated optics were pioneered by Carl Zeiss -- and this superb lens features T* (T-Star) coating that virtually eliminates the lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces.
  • Superior Large-Aperture Performance: Like other large-aperture Carl Zeiss lens designs, this f1.4 lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture.
  • SSM (Super Sonic wave Motor): Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied.
  • Glass-Molded Aspherical Lens Elements: These precision lens elements correct distortion for sharper, more visually accurate images.
  • ED (Extra-low Dispersion) Glass: Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss lenses to eliminate chromatic aberration by correcting certain wavelengths of light

Questions & Answers Powered by TurnTo®

Questions about this item:

Hassan a  Is this lens suitable to use with Sony Alpha 850 full frame?
ANDREW B  This lens should work fine with the Sony a850 as I own two a99's. Unfortunately, I got a bad copy and it is in the process of going to the Sony Laredo service center to get re-calibrated as it back focuses. But I'm sure this is an isolated problem as all of my other Sony Zeiss lenses (and I own ALL of them) have all been perfect.
Shopper  Is this an e mount lens? Compatible with Nex 6?
Andrew R  Unfortunately no, this lens is for A mount cameras. NEX series cameras would require an adapter.
