| Re: Nikon 18-200 VR vs. Sigma 18-200 OS Lens It's not a DX lens, but I have the 70-200/2.8G VR lens, and it's the sharpest lens I have. I have three Sigmas, a 14/2.8, 17-35/2.8-4 and 28-105/2.8-4. The 14 is good, the 17-35 is sharp enough but will miss focus on me, and the 28-105 isn't sharp until you get below 5.6. If price is no object, I would buy the Nikon. |
