ive been looking for a cheap new lens and this is what i found, i know sigma is 3rd party for nikon but are they reliable?
Amazon.com: Sigma 70-300mm f/4-5.6 SLD DG Macro Lens with built in motor for Nikon Digital SLR Cameras: Camera & Photo
ive been wanting to shoot zoom and up close
Let me swat you upside the head so to speak. You want a Sigma for your Nikon while at the same time you use this signiture following your posts? "buying a DSLR just to shoot on automatic is like buying a Lamborghini and not even taking it out of 2nd gear "
Come on man! Drop the signature or buy a Nikon lens. Come on man! (popular Football thing to say lately)
I owned 2 sigma lenses when I got my first Nikon lens. I took half a dozen test shots to verify If my eyes were deceiving me or was it really that night and day difference. I immediately sold the Sigma lenses and swore I'd never buy another off brand with out testing it and comparing it to a Nikon. Or reading a trusted reviewers comparison between the two. Thus I own a Tokina 12-24 I did not personally test before buying.

Here is what the same reviewer says:
"Nikon and Canon are each primarily lens companies, not camera companies.
It's sad to see people buy good cameras and put off-brand lenses on them.
...
Did you know that Nikon is one of the world's leading makes of professional laboratory microscopes, often beating out Zeiss and Leitz? Nikon also makes the million-dollar lenses and mechanical steppers used in semiconductor manufacture. They have a 37% market share. These lenses and mechanics resolve at 45 nanometers, or less than one-tenth of a wavelength of visible light? That's over 10,000 lines per millimeter! See
Nikon Precision."
