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

Canon 70d. So, in LV mode, the contrast focusing method is used. Here the lens gives an excellent, sharp picture. But focusing through LV is notoriously slow and eats up a lot of battery. Let's move on to the viewfinder (phase detection autofocus) and find huge differences between pictures taken with different focus modes. Both at close and at long distances, the lens misses very much. (Focused on the center point) "Buy a sigma dock, adjust the lens and enjoy." This is what I did, but it didn't help. Set up 2 full days. We correct one value - it floats in the neighboring value, etc. Ok, let's say all this can be picked up. But the lens goes into back / front focus with absolutely no logic. That is, now it will go into the back, you will knock down the focus (be sure to knock it down, you need a clean focus), focus again at the same point - already front focus. And sigma dock will not save you from this. Constant spans in + or -. It’s also funny about the dock: “you can ate the lens firmware” - it doesn’t ate, as there was version 1.01 on the lens from the store, so it remained. And this is provided that the focus problems are known. USB dock is a very dubious decision: "Let users pay for the fact that we make crooked lenses." Translation in the program for setting up sigma: instead of the word "Search" it says "Posik". A trifle, but it perfectly shows the attitude of sigma to its product - negligent. Additionally (photo taken on a tripod at an open aperture): All sorts of pros will downvote my review for this, like "unprofessional, where is the super target", but even without this everything is clear: • https://yadi. Sk/i/3jY7ozAAntYGk - to the point through the LV mode. The focus on the ruler should be the number 8. • https://yadi. Sk/i/sIOzZD5wntYW3 - to the point by the phase focusing method. "Fly". Infinity was hard. 100% increase. • https://yadi. Sk/i/Wpe6evgpntXR9 - Live view. • https://yadi. Sk/i/rbxtRSgSntXJJ - Through the viewfinder. Took it back to the store. P. S. Read more forums and social networks, in addition to reviews on the market.
