Product Review
Upon first inspection, fit & finish are on par with Nikon's own 18-200, 16-85, etc. I would say that it's very-very close to the build, size/weight of my 16-85. It's a very decent build, solid plastic, and has smooth operating zoom and focus rings. This lens has a metal mount, weather seal gasket, and a focus distance window. Why didn't I buy the 12-24 f/4? The Nikon 10-24mm will give me 10mm at f/3.5, which works fine for me. The 12-24mm will give me 12mm at f/4, which is neither wide or bright enough. I hear so many folks state "but the 12-24 is a constant f/4." I've also heard people say that "variable aperture" lenses are indicative of cheaper or consumer-grade lenses. I don't necessarily agree with that. I believe most lenses are a touch sharper when stopped down from their maximum aperture anyway, therefore a constant f/4 with the 12-24mm doesn't necessarily attract me to that lens. I wouldn't shoot the 12-24mm at f/4 anyway, especially for landscapes. In my opinion, the 10-24mm makes more sense with it's wider field of view. (More Detail...)
