I have been waiting for such a lens for two years. © To be honest, since 2022. Pros below: 1) This is the first high-quality fast aperture in the E system, at an adequate price. The rest of the lenses are soap soap, or for deputies, kidney donors, children of oligarchs, thieving officials, movie stars and pop stars. And for us, ordinary 2022 hard workers, with a middle-class salary, sigma made this gift. 2) Very sharp at all apertures. Not enough light for the landscape? Set it to f/1.4 and everything stays sharp. Little light in the museum? Put 1.4. Just catch the focus and it will be clear. Don't worry, there are no compromises. Little light at the concert? You know what to do. Already at f/1.6 it's sharper than the 16-50f3.5 Blinokit, and at f/2 it's sharper than the Blinokit clamped down. Imagine what he is doing at 3.2-5.6, but rather download the pictures, it's just something. At first, it just breaks the pattern, but you quickly get used to the good. 3) DOF is really wide at such focal lengths. Take the IPIG calculator and see for yourself. In a room with several people, you can set f / 1.4, step back 3-4 meters and all people will be in focus. Focus at 9+ meters at f/1.4 is sharp at infinity. 4) Dust and moisture protection is declared in some places, in some places it is not. The Japs hesitate to answer unambiguously. The promise was removed from the site, but it is obvious that at least they tried. It's better than not trying at all. In the rain and snow, in principle, I shot, while the norms. 5) Beautiful, large, black, rubberized. With a brilliant letter C (I think it means Harsh / Fast / Steel / Highly Sharp / Self-focusing). If you put on a hood, you can immediately see who is the real photo man with the letter C, though from the 2022 C, and not like Superman. :-) Has cons: 1) On old NEXs with contrast autofocus, it only focuses in AF-C mode, and slowly. Because of what (and not only) I will change the camera. 2) Heavy. I understand that it could not be otherwise, a bunch of healthy lenses, metal, but I will not stop dreaming about a world where a coin has three sides at the same time (cheap, high quality, convenient). Never three at the same time. They would make it from composite materials and titanium, it would be easier, but more expensive. And if the mass of lenses was smaller, there would not be that quality. 3) Lovers of spectacular bokeh and depth of volume - pass by. Not that focal. He washes the object, the cat and somehow a half-length portrait, but he is not for that. 4) For video, it will not work without a steadicam, because there is no built-in stabilizer. Although I will soon take a Sony a6500 with a matrix stub, it can depict something, but this is unlikely . 5) It seems that people complained about the size of the filters . I don’t know . I haven’t used them for five years. I don’t even know what kind of thread there is, but the lid is big, a fact! Save up immediately for the filter, who needs it.
