Sony has announced FE 50mm F1.4 GM, a new full-frame G Master lens for its E-mount cameras such as the Sony A7R V.
As one of Sony’s G Master lenses , the Sony FE 50mm F1.4 GM features an advanced optical design and an 11-blade circular aperture to deliver attractive bokeh.
The FE 50mm F1.4 GM’s optical construction includes two XA (extreme aspherical) elements to correct field curvature and most types of aberration. There’s also an ED (extra-low dispersion) element to reduce chromatic aberration and deliver sharp images with no chromatic aberration.
Sony’s Nano AR Coating II has also been utilised to suppress reflections and the front element has a fluorine coating to make it easy to clean. In addition, the lens barrel is dust and moisture resistant.
Autofocusing is handled by high-thrust XD (extreme dynamic) linear motors.
When the autofocus system is used, the FE 50mm F1.4 GM has a minimum focus distance of 0.41m, at which the magnification is 0.16x. The focus distance reduces to 0.38 meters and the magnification rises to 0.18x in manual focus mode.
Compact design
Thanks to the advanced optical construction, the use of linear motors and a compact aperture unit, the Sony FE 50mm F1.4 GM is only 80.6 mm in diameter and 96.0 mm in length. It weighs 516g. This means the new lens is 33% lighter and 15% smaller (by volume) than conventional comparable lenses – such as the Sony Planar T* FE 50mm F1.4 ZA.
Sony also claims that the autofocus system is up to 1.9x faster than conventional lenses. As well as using Sony’s high-thrust XD linear motors, the new lens has an advanced algorithm that helps to deliver smooth, responsive focus drive that’s especially beneficial when tracking a subject while shooting video at 120 fps.
Sony has also given the FE 50mm F1.4 GM the latest technology to reduce focus breathing and it supports the breathing compensation function found in the most recent Sony A7-series cameras.
The manual focus response is linear, which means it responds directly to the ring movement in a repeatable fashion.
Further good news is that for the first time on a Sony prime lens, the FE 50mm F1.4 GM has an iris lock switch. There’s also a focus mode switch and two focus hold buttons that can be customised to access a range of functions from the camera’s menus.
The filter thread is 67 mm.
