Comments about Tamron Tamron 11-18 mm F/4.5-5.6 SP AF Di II LD Aspherical (IF) Lens for Nikon:
This lens is reasonable and great for wide angle. I don't use it as much as I would like because I do lot's of sports and it's just too slow for that, but when I need photojourlistic shots or wideangle...it's first choice.
