For older cameras or videographers a great option. Not suitable for photographers with a modern crop, you can put it on ff, but why a wild vignette? There were sigma art on the mic, they worked flawlessly. I bought a canon 35 is and was amazed - the marriage disappeared, in general, it always removes everything. I sold all the sigmas - like a nightmare of the past now. They told me that they only bought native optics - but I heard enough of corrupt reviewers who drove synthetic tests, or, well, reviewers of new products, who never took pictures, but only tested and fell for it. How much time and other things wasted.
