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


Sony has introduced its 60th E-mount lens — the 50mm f/1.2 G-Master — that it hopes will show that not solely can it proceed to make compact, light-weight primes but in addition may also accomplish that whereas competing with the quick aperture lenses of each Canon and Nikon.

One in all the extra distinguished speaking factors that emerged when each Canon and Nikon introduced the RF-mount and Z-mount and compared to the Leica L-mount was that each one three have been superior to E-mount as a result of, supposedly, Sony by no means designed the E-mount for full-frame. This statement was originally made by Leica’s Stephan Schultz and appeared to unfold extra rapidly than it could possibly be debunked. Which, by the means, Sony did in 2019.

As if to construct on that, Sony’s 50mm f/1.2 G-Master manages to mix the wide-open aperture of f/1.2 with a compact and light-weight design that’s primarily the identical dimension and weight as the Zeiss Planar T* FE 50mm f/1.4 ZA: It’s the identical size, identical width, and a half cease quicker.

The lens’s dimension is thanks to 2 foremost components: 1) The focusing system in place and a couple of) the lens components used.

When in comparison with Canon and Nikon’s 50mm f/1.2 lenses, every makes an attempt to deal with focusing in several methods. Canon makes use of a rotational ultrasonic motor (USM) that may really bodily transfer bigger lens components forwards and backwards (that is seen on the entrance of the lens). Nikon’s system is to make use of an inside focusing system based mostly on a rotary stepping motor.

Sony says that each these programs are inferior to its linear actuator focusing system that it has been utilizing in its more moderen high-performance G-Master lenses. The corporate claims that its 4 excessive dynamic linear motors (XD linear actuators) present the excessive thrust effectivity wanted to precisely place the lens’s two giant focus teams in a floating focus mechanism managed by its devoted lens drive algorithm. These actuators additionally contribute to a quiet focus drive.

Due to that motor, Sony can promise a 100% hit fee with an inch depth of subject at as much as 30 nonetheless frames per second. It will probably additionally shoot at 120 frames per second in 4K with out lacking focus as evidenced by clips confirmed to PetaPixel throughout a briefing. It ought to be famous that these are in excellent situations and Sony doesn’t promise it will occur each time, flawlessly, however the indisputable fact that these benchmarks may be hit in any respect remains to be spectacular.

The lens is constructed of 14 components in 10 teams, three of that are excessive aspherical components (XA) that Sony says reduce aberrations, permits the lens to keep up sharpness and readability from the middle to the edge, and as talked about contributes to the lens’s small dimension. It has a minimal focusing distance of 0.four 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, specifically these made by Canon and Nikon, are much less efficient at sustaining distinction out to the corners than this lens can (based mostly on MTF charts). In instance photographs proven to PetaPixel, the stage of sharpness at the middle of a picture was solely barely higher with the Sony, however the edge efficiency was noticeably higher. Sony says that its Nano AR Coating II successfully minimizes inside reflections in order that flare and ghosting don’t happen.

The defocused areas are easy due to a newly-developed 11-bladed round aperture, and the aforementioned XA components suppress “onion ring” bokeh that’s typically seen in lesser high quality optics.

As is generally discovered on Sony optics, the 50mm f/1.2 G-Master includes a de-clickable aperture, programmable focus management buttons, a fluorine entrance ingredient coating, and a spotlight mode change.

The Sony 50mm f/1.2 G-Master can be accessible on Could 13 for $2,000. Moreover, when requested about doable provide chain points, a Sony consultant assured that there are not any present challenges in manufacturing and that there ought to be sufficient items to fulfill demand.
