Alright well I have a Nikon D40 and have been wanting to get a faster lens. Right now I have the 18-55mm kit lens and the 55-200mm AF-S VR. I have been looking and reading about two lenses in particular a lot The sigma 70-200mm f/2.8 HSM II and the Tamron 17-50mm F/2.8 XR di-II. Problem is the Sigma 70-200 $800 which seems like a lot to spend on a lens, especially when I have the 55-200mm which I like and I feel like I will miss VR. Basically my question is are there any telephotos out there that will out perform my 55-200mm VR that cost around 300-500 instead of $800? If not I think I might just go with the Tamron lens because I feel like my 18-55 is not very good. EDIT: Damn! I meant to post this in the equipment section. If a mod see's this can you please move it?
