Sony FE 50mm f/1.2 GM lens review (Full-frame & APS-C)
2 g master. This is sonys 60th lens for their mirrorless e mount camera system, and they have saved something special for the occasion as this is the brightest aperture lens theyve managed to produce so far with an aperture of f 1.2. That brings it in line with canon and nikons latest flagship offerings and ill probably be making another video in the near future, comparing all three of them anyway. This sony lens will set you back an eye watering 2 hundred pounds in the uk or two thousand us dollars a simply huge amount of money for a 50 millimeter lens. But if it turns out to be the best on the sony system, then well you simply have to pay for that privilege and theres. No denying that it would be an especially useful lens to spend the money on. Everyone loves a bright aperture, 50 millimeter lens. They can offer you some serious background separation, but their angle of view is wide enough that your backgrounds still play a really interesting role in your final image. These lenses are excellent for wedding photography, street photography, portrait work well just about everything really and that bright aperture of f 1.2 lets in about 33, more light than an f 1.4 lens, giving your images a little boost, although the difference, admittedly, is not major lets. Take a look at this little monsters, build quality first, its rather big and feels just a little front heavy on your camera.
Its body is mostly made of plastic, but it certainly feels very solid and tightly assembled. It weighs nearly 800 grams or a little over one and a half pounds so its a bit on the weighty side. The lens is advertised as being quite well weather, sealed and it does indeed have a slight weather ceiling gasket on the rear mount. There are a lot of control points on this lens too, which is always really useful. It saves you having to fiddle around changing things in the cameras options. Menu first comes the aperture ring which can be set to click, nice and confidently. Every third of a stop or it can be set to turn smoothly, which yields some lovely, smooth, aperture changes when video making we also get a manual focus switch and a couple of focus hold buttons on the side, then comes a rubberized manual focus ring which turns Satisfyingly smoothly, as you can see here, the lens exhibits some moderate focus, breathing zooming in a fair bit as you focus more closely, and that can be a little annoying for video makers. Now lets see about the autofocus system. It works quickly, accurately and silently here, pretty impressive than f 1.2 lens, although sometimes it goes the wrong way before finding your subject properly, the lens comes with a nice carry case and a very good quality hood, which is flocked on the inside, and it has a Rubber trim on the outside edge, it has a 72 millimeter filter, thread size and does not have image.
Stabilization overall were looking at wonderful, build quality here, which really makes a difference. The lens is very enjoyable to handle and use out in the real world and im especially impressed with its fast silent, auto focus system. Much more important, though, is the lenses image. Quality lets start by testing it on a full frame camera. My 42 megapixel sony, a7r iii in camera, corrections are turned on at f 1.2 straight away in the middle of the image we see. Razor sharpness and excellent resolution lets take a look over in the corners. They look fantastically sharp, also, although not quite as good as the middle and theres just a touch of ghosting and color fringing on contrasting edges, particularly in the very corners. You have to be really pixel peeping to spot. That, though, stop down to f2 for full contrast to return in corners as well as more brightness. This is a wonderful image: quality at f, 2.8 theres, a minuscule further tiny improvement and the lens stays the sharp down to about f11, where the effects of diffraction begin to have a softening effect and at f16 the corners are noticeably softer, as you would expect. Overall, absolutely fantastic image: quality on a full frame camera here, the best ive seen from a 50 millimeter lens on the sony system so far and now lets see how it performs on an aps c camera my little 24 megapixel sony a5100 as on a full frame.
Camera image quality really shines in the middle of the picture straight from f 1.2. Looking virtually perfect the corner image quality is noticeably softer now, but still very good. Indeed, f. 1.4 looks a little sharper. There f2 looks excellent and f 2.8 perfect, so its a wonderful performance on an aps c camera here, but you do need to stop the lens down just a little in order to get the sharpest possible quality in the image corners. All right lets look at distortion and vignetting now on a full frame camera. These images are taken with in camera, corrections turned off. We see some notable pin cushion distortion being projected here and at f 1.2. The expected strong vignetting in the corners stop down to f2. F, 2.8 and f4 to see that vignetting alleviated, but it never completely goes away so its a slightly weaker performance than average here, but no alarming problems. The lenss minimum focus distance is 40 centimeters a little bit closer than average for a 50 millimeter lens close up image. Quality is notably soft at f 1.2, although contrast is still quite good. Stop down to f2 to see very good sharpness returning and at f 2.8 resolution is excellent. Again lets see how well the lens performs against bright light. Its a fairly good show here, some rather broad flaring, can be seen when bright lights are directly in the picture, but its fairly translucent, and not really bothersome at all.
So thats encouraging to see lets take a look at coma levels. Now, on this g master, lens bright points of light and the corners dont really see any smearing, even at that maximum aperture another fantastic thing to see, lets zoom out and take a look at the lenses sun, star situation. You have to stop down to f, 8 or ideally, f, 16 – to get any kind of impressive sun stars here now lets see about this lenses bokeh a vital factor for lens with such a bright aperture. Everything looks lovely and soft here, as you would expect for a lens of this price, although, as expected, you can see a little cat eye shape to blockables around the edges of the picture at the brightest apertures. However, at f 1.2, as you can see here, longitudinal chromatic aberration is a little bit of an issue. We see some purple and green bokeh highlights before and after the plane of focus stop down to f2 and those colors are beginning to go away and at f 2.8 they are virtually gone overall. The sony, fe 50 millimeter, f, 1.2 g master – is pretty much everything you could dream about from one of the most modern top of the line and expensive 50 millimeter optics currently available. Today, it is a complete and utter joy to handle laser sharp with great image quality in almost every other field and the best available auto focus system for such a lens.
Its comforting to know that nowadays, if you spend a huge amount of money on such a lens, youre, pretty much guaranteed to get what you pay for well, unless its a zeiss lens, of course. Well, anyway, before i get in trouble by triggering any fanboys too hard lets just wrap it all up by saying that this sony lens obviously comes highly recommended thanks for watching everyone. I hope you enjoyed this review. I love putting these reviews together, but they are time consuming and sometimes costly.
