Third party lens manufacturers are usually best given a wide berth if you want really good glass. This offering from Sigma is awesome. I use this lens professionally and regularly produce twenty inch wide prints. Chromatic abberation is minimal far less than expected from a lens offering this angle of view (15mm equivalent on 35mm). Barrel distortion is there at 10mm but this is no drawback after all the results from this optic are meant to be dramatic. I simply cannot fault the resolution from its use on my D200. Save money go for the Sigma over the Nikon equivalent you wont be dissapointed.
