    Just interested in finding out peoples views on these 2 lenses. Ive read some reviews already on dpreview and fredmiranda but want to know what people here think.

    Both are about the same price. Tamron has shorter length but f2.8 all the way through. Sigma has longer length but smaller aperture on the long side.

    Anyone tried these lenses out?

    A previous post of mine may be of some help: link

    In my case I went for the 18-55is kit lens. (keeping it on the cheap side and spending money elsewhere.)

    happy choosing. let us know what you go for.
    If I were to choose between the 2 you are looking at I'd go for the 17-50 2.8.

    Have a look online for the breakdown on 2.8 to 4.5 and at what focal length the changes are.

    Cheers

    I should say that i have the 18-55 (non IS) kit lens, and am looking for a must sharper and faster lens that i can use as walkabout lens. Also have the 50mm 1.8 and sigma 70-300.

    I have the Sigma 17-70 and it stays on my camera most of the time. It would be nice if it was 2.8 all the way but for me its not really an issue as I usually take landscape type pictures where mid apertures are the norm.

    build quality is good for the price and image quality is excellent- definitely a good step up from the kit lenses.

    I think it boils down to whether you prefer the continuous 2.8 of the Tamron over the extra reach of the Sigma. I think either would serve you well if you don't need the better build quality and focussing speed of the pro series lenses.

    Go for the Sigma 17-70 in my opinion. If you go for the 17-50, then you will have a big gap in your focal range from 50 to 70mm which is where you should be shooting your portraits on a cropped D-SLR camera. You will probably be stepping down from f2.8 on the Tamron lens anyway to get better sharpness.

    The copy I had of the 17-70 was razor sharp on my Nikon D200, I only sold that lens when I went full frame, and if I could have kept it I would have. Just my two cents...
