Thanks for the input.

I have given a try of Sigma 17-50.

1. Optically it was similar to my 7year old tamron. I like Sigmas warm colours, slightly beter contrast and significantly beter bokeh, but I like tamron corner sharpness straight from 2,8.
   
2. AF – I have not seen any difference between two in terms of AF accuracy and speed. Anyway both ware worse compare to any canon lens.
   
3. Build quality – Tamron and Sigma have chosen different approach. Tamron can survive longer in “MY” everyday use, but once broken it is not repairable item. Sigma will brake easy but repairment process seems intuitive.
   
4. Price – Sigma I can alny find it new for 400Euro. Tamron new 330Euro. Used 150Euro.
   

 

I have returned sigma and will search for second hand tamron, with only 50euro above kit lens is not brainer.

 

Thanks,

Miro
