    Which one is better wide open?
    Which one is better overall?

    I know that the sigma is big ..what else?
  2. Hi Smodak
    Sigma is surely bigger and better built; it gives you a more pleasant touch sensation and a wider area when framing (much more noticeable than the difference between 70 and 75 on the tele end) but also forces you to get 82mm filters. Optically, from what I read in the past, people found it a bit more soft than the Tamron, and that's why i got this one. Once I also found a review where they proved with a good sample you could really compare results to the 28-70 Nikon, build quality aside.
    If you give a look here, you can ask by yourself:

    SIGMA => http://www.pbase.com/cameras/sigma/2470_28_ex_dg_asp_df
    TAMRON => http://www.pbase.com/cameras/tamron/sp_af_28-75_28_xr_di_ld_if

    Give also a look to the comments. I bought mine for about 450$ while Sigma was almost at 600$ here. Later I'll post something else useful for you

    I have had both in the past, and the Tamron blew the Sigma away. Plus, it's much lighter and takes 67mm filters.

    I have a Tamron 17-50 now and it is simply amazing.

    Care to explain? Sharpness? Contrast? IQ? Color? Wide open performance?
  6. From what I've heard, (and I only have the Tamron 28-75) That the Tamron is better than the Sigma 24-70, BUT the Sigma 24-60 is a fantastic lens.

    USuall comparisons are sharpness, But from what I've seen the Tamron 28-75 is very sharp at f2.8. Theres lots of threads that compare it to the Beast (Nikon 28-70 f2.8). Also as an added bonus the Tamron is full frame, where as the Sigma 24-70 is not (Not sure about the 24-60).
  7. Hi Lexiticus,
    I'm sorry but I think you're confusing the 24/70 with something else, I can assure you that that lens is for full frame, even if with inner lenses coatings optimized for digital cameras (DG labeling). Besides, a 24-70 designed ONLY for digital wouldn't have any sense, being a 36mm if you see, all Sigma, Tamron, Nikon and Tokina are starting around 16-17-18mm at the wider end. So is also the 24-60.
