Review on Sigma 18-35mm F1.8 Art DC HSM Lens - Canon Compatible, Black (210101) by Amar Amar ᠌

I’ll make a reservation right away, my carcass is 70d, but it’s not just the incompatibility of the carcass and the lens. Unfortunately, I can't mention any of the advantages! So I'll write everything else. 1. The lens never focuses on the face and under no circumstances, you put a central point, but he doesn’t see it, it seems that the lens simply doesn’t understand the camera settings, for a long time I couldn’t understand the reason why it doesn’t finish it, then it interrupts, but on the face no way! Then it dawned on him, he does not focus on plain objects in principle! With the aperture clamped, you will not see this, but with aperture 1.8 you can see very well! 2. Why aperture 1.8 is needed is not clear at all, because at dusk it does not focus! Yes, there is 1.8, but in the evening there will be misses in 100% of cases and you can’t do anything about it even with the docking station! You won’t pull the lens in the morning and in the evening from the camera to the docking station and then back 50 times to adjust it for daylight and darkness? These actions will very quickly clog the camera with dust. It has been tested on personal bitter experience. Now minor flaws, of course, they are annoying, but tolerable. 1. Backlash with a carcass. 2. Inside, when you pick up the lenses, they rattle. The general impressions are as follows: the back-front cannot be corrected either by an amendment in the carcass or by a docking station, not by both of them. It is configured for shooting either at short distances up to about 2-3 meters or at long distances. It will not work to set it up for universal shooting of everything that we would like. When you set it up for the near ones, it will wildly interrupt to the far ones, when you start to adjust the far ones, everything will go astray for the near ones and there will be wild dregs, you won’t see where the focus has gone in principle. In general, I will no longer contact Sigma!
