Been up and about recently about buying some new gears. I've been using a D60 for about 1 and a half years now, bought it in December 2008. Great little camera, good picture qualities, shame about the no-AF-motor-policy though. Anyway, I'm upgrading this year ! Getting the D700 next week probably, or sometime around June. I'm looking to buy the D700 along with a wide-angle lens, as I don't have any FX Wide Angle in my arsenal at the moment (my current lenses Tamron 17-50mm, Sigma 10-20mm, both of which I will sell soon). I'm looking for a decent wide-angle lens, light, small, cheap and fast. I came across the Nikkor AF 20mm f/2.8D which I thought was impressive. I'm looking to use this lens for walking around, travelling, and landscapes. On the D700, it'd be wide (not the widest but still) so thats not a problem. I also looked at the Sigma 20mm f/1.8 which offers a faster max. aperture but I'm not convinced it offers a better image quality than the Nikon. So if you guys would just let me know what I've been missing, is there a better option for a cheap, decent wide-angle lens? Better yet, post up some pros and cons about this lens, or some reviews would be good too!
All of your help will be greatly appreciated, thank you!
