All I know - all reviews and tests I read, I don't own the lens - say, that the older non-VC Tamron 2,8/17-50 has by far better IQ.
I tested the old Tamron 2,8/17-50 and the Sigma 2,8/17-50 OS. Tamron has exceptional cost/performance ratio, is smaller and lighter, zoom-ring works smoother, IQ is similar. BUT: Sigma has OS.
It's up to you, whether OS is worth the extra money and weight.

Hello Lars,
Thanks for the info. In this focal range I only have Tamron 17-50 non VC. I have never test it against other zooms. My experience match very well the Internet reviews of this lens except only one criteria, the build quality. Seay it other way around – there is no Internet review site that says that Tamron 17-50/2,8 has very good build quality.
I have this lens for 5 years. As amateur photographer I use this lens to photograph my kids and occasionally for wedding parties. My passions are see/landscapes and I find this focal range boring. If I need exceptional IQ or zoom range or speed I attach this lens.
- It is the most flare resistant lens that I have.
- A little bit soft at 2,8 but above 4.0; 5,6 is razor sharp.
- With little care survive in any outdoor conditions. Including two fall off from tripod, once in concrete and once in grass/soil. Mechanical and optical it is as good as new.
