    Both work equivalently the same. Just that the pricing is different and what-not other factors like build etc etc.

    Based on the reviews in

    Tamron seem to be better than Sigma in term of sharpness

    Sigma more quiet than tamron when focusing.
    Tamron is sharper than sigma.
    Tamron focus faster than sigma.
    Tamron zoom in clock wise direction, sigma other way round.
    Tamron filter size is 67mm, new sigma 17-50 with micro is 77mm (67mm non micro)
