yup that's the one,
also consider, if you have time, the new Nikon 18-55 VR lens, just like the kit lens but with VR which will buy you up to 3 stops!
I had that lens on my camera yesterday... and let me tell you... its nowhere near the crispness, clarity or quality of output that the Sigma does (that Nikkor is not even a F/2.8!).
I sincerely feel that the Sigma 18-50 HSM is the best option available today (for now at least) for the Nikon people.
Three things that I do not like about my 18-50:
- The location of the focus ring. Takes a change in technique else the lens screams at you as you hold the ring by accident
- Stupid edge press lens cap, cannot take it off with a lens hood on (at least not easily).
- Direction of the zoom is backwards compared to Nikkor lenses
Absolutely NONE of these things detracts from the lens for me, though.
Oh, the macro magnification on this lens is not a 1:1 but rather a 3:1, but for me, to have a macro function on this lens is just another plus. A 1:1 macro would give me a greater magnification and if you have a greater focal length prime, then you could get a 1:1 magnification like with my Sigma 105mm macro F/2.8 prime like this for a farther distance:
