How do they compare to the Art series?
Hi, Jakob! SIGMA Art line lenses do feature faster apertures, dust-and-splash resistance, and top optical quality, but these new I series lenses offer comparable performance in a smaller, all-metal, affordable package. There are certainly good reasons to consider Art lenses over these, but for portable performance with a unique look and feel, the I series are hard to beat. The best way to decide what you prefer is to try both (at your favorite SIGMA Authorized Dealer, of course.) ????
I love my ART lens (24-105mm) that I use on my Sony a99 II….alas, I am currently at that critical juncture of “do I go mirrorless?” since the a-mount flagship Sony a99 II (and a-mount lenses) have been discontinued. The Sigma I lenses sound like a great line that will fit perfectly to the mirrorless portability and smaller size, yet they maintain great affordability packaged with smaller (and all metal!) size. As I write, I’m staying with my much bulkier equipment as it fits “me”…but if (or when?) I were to go mirrorless, I’d give Sigma I lenses a serious look. Sigma has earned my trust atop the field of after-market lenses, and I am persnicketty, to say the least. 🙂
Also for Canon R mount?
