Sigma has been snobbed a lot in the past.
I've always loved them. I admire how a small family-owned company can compete with the big guys. In spite of limited resources for R&D they have some unique lenses and they managed to design that jewel that the Foveon is. If they did a FF version (at a reasonable price, the SD1 has been the greatest marketing failure of the photographic history) I'd be all over it. In fact, they seem the be only ones who are really into innovating - besides that huge giant of Sony.
I had the first version of the 17-70mm in Canon mount, and I'd never had swapped it with the twice-as-expensive Canon 15-85mm. Just as sharp, a bit of reach less and no OS but almost a full stop faster. The color rendition was to me also much more balanced. It's when I first fell in love with Sigma.
On an average, in my opinion, Sigma lenses have always offered if not better quality, at least outstanding value. Now that the son is in charge of the company, it's clear that he doesn't share his father's view of being a niche or a respectable second choice. He wants to be up there.
The 35mm has been a superb debut. Great build, great sharpness, great AF even wide-open and with no AFMA, great colors, nice bokeh and a reasonable price. It makes my Nikon 85/1.8G (great lens) look like the glass was carved out from a Coca Cola bottle and encased into a toilet paper roll. It's becoming so redundant that I'm thinking of selling it.
I'm only too happy. I'd be extremely happy with an all-Sigma lineup. Who knows, in 10 years from now we might all be shooting Sony or Samsung cameras and Sigma lenses
