Sony Unveils the 50mm f/1.2 G-Master Prime Lens

Sony has launched its 60th E-mount lens — the 50mm f/1.2 G-Master — that it hopes will present that not solely can it proceed to make compact, lightweight primes however as well as might also accomplish that whereas competing with the fast aperture lenses of every Canon and Nikon.

One amongst the further distinguished talking elements that emerged when every Canon and Nikon launched the RF-mount and Z-mount and in comparison with the Leica L-mount was that every one three have been superior to E-mount because of, supposedly, Sony certainly not designed the E-mount for full-frame. This statement was originally made by Leica’s Stephan Schultz and appeared to unfold further quickly than it may presumably be debunked. Which, by the means, Sony did in 2019.

As if to assemble on that, Sony’s 50mm f/1.2 G-Master manages to combine the wide-open aperture of f/1.2 with a compact and lightweight design that’s primarily the similar dimension and weight as the Zeiss Planar T* FE 50mm f/1.4 ZA: It’s the similar measurement, similar width, and a half stop faster.

The lens’s dimension is because of 2 foremost elements: 1) The focusing system in place and a few) the lens elements used.

When as compared with Canon and Nikon’s 50mm f/1.2 lenses, each makes an try and take care of focusing in a number of strategies. Canon makes use of a rotational ultrasonic motor (USM) which will actually bodily switch greater lens elements forwards and backwards (that’s seen on the entrance of the lens). Nikon’s system is to utilize an inside focusing system primarily based totally on a rotary stepping motor.

Sony says that every these packages are inferior to its linear actuator focusing system that it has been using in its extra moderen high-performance G-Master lenses. The company claims that its four extreme dynamic linear motors (XD linear actuators) current the extreme thrust effectivity wished to exactly place the lens’s two large focus groups in a floating focus mechanism managed by its devoted lens drive algorithm. These actuators moreover contribute to a quiet focus drive.

On account of that motor, Sony can promise a 100% hit charge with an inch depth of topic at as a lot as 30 nonetheless frames per second. It would most likely moreover shoot at 120 frames per second in 4K with out missing focus as evidenced by clips confirmed to PetaPixel all through a briefing. It must be well-known that these are in glorious conditions and Sony doesn’t promise it’ll happen every time, flawlessly, nonetheless the incontrovertible fact that these benchmarks could also be hit the least bit stays to be spectacular.

The lens is constructed of 14 elements in 10 groups, three of which can be extreme aspherical elements (XA) that Sony says scale back aberrations, permits the lens to maintain up sharpness and readability from the center to the edge, and as talked about contributes to the lens’s small dimension. It has a minimal focusing distance of 0.4 meters (~15.75 inches) with a most magnification of 0.17x.

The Sony 50mm f/1.2 G-Master weighs 778 grams, which is notably lighter than Canon’s 50mm f/1.2 which weighs 950 grams and Nikon’s 50mm f/1.2 which weighs 1090 grams.

Sony claims that its competitor 50mm f/1.2 lenses, particularly these made by Canon and Nikon, are a lot much less environment friendly at sustaining distinction out to the corners than this lens can (primarily based totally on MTF charts). In occasion pictures confirmed to PetaPixel, the stage of sharpness at the center of an image was solely barely increased with the Sony, nonetheless the edge effectivity was noticeably increased. Sony says that its Nano AR Coating II efficiently minimizes inside reflections so that flare and ghosting do not occur.

The defocused areas are simple attributable to a newly-developed 11-bladed spherical aperture, and the aforementioned XA elements suppress “onion ring” bokeh that is usually seen in lesser prime quality optics.

As is mostly found on Sony optics, the 50mm f/1.2 G-Master features a de-clickable aperture, programmable focus administration buttons, a fluorine entrance ingredient coating, and a highlight mode change.

The Sony 50mm f/1.2 G-Master may be accessible on Might 13 for $2,000. Furthermore, when requested about doable present chain factors, a Sony advisor assured that there will not be any current challenges in manufacturing and that there must be adequate objects to satisfy demand.
