I am looking to buy a new lens for my Nikon D50 pretty soon and am looking at the 18-200 type lenses which i cannot decide on which one to get the Nikon VR lens is a little out of my budget so I have narrowed it down to
the Sigma 18-200mm F3.5-6.3 DC
the Quantaray 18-200mm F3.5-6.3 DC
the Tamron 18-200mm F3.5-6.3 XR DI 2
Those are the ones I am looking at unless I can fond a Nikon VR for under $500 (I know I am dreaming )
Since I am new to the Digital SLR world any and all advice is greatly appreciated!
