Many will consider such a decision controversial, but he did it meaningfully and has never regretted it. Once upon a time I heard about the appearance of sigma 18-35 / 1,8. I bought (together with 60D), tried it and the next day I sold 24-70 and the first nickel. Since then, I have never regretted it. The second camera at weddings worked 5dm2 and 70-200 / 2.8. I waited a long time for a similar zoom from sigma to come out. Waited. I bought 50-100 / 1.8 and took another 60D camera. Already filmed a wedding and do not regret buying. Without hesitation put up for sale brand2 and 70-200 / 2.8. And yet, I have repeatedly met questions on the forums about how cropped SIGMA ART lenses behave on a full frame - there will be a vignette on all focal lengths. Yes, it can be corrected in the editors, but the fact remains.
