Hi, I currently shoot with : Nikon D90 D40 Nikon 18-55 (d40 kit) Nikon 50 1.4 Sigma 10-20 f4 Sigma 18-200 3.5 I'm looking to go a step further and get wither the nikon 14-24 2.8 or 24-70 2.8 With a view of shooting with my D90 until I can get the D700 or it's replacement. I will be shooting mainly landscapes so I am leaning towards the 14-24 but i'm not sure about it's quality on the D90. I may be able to scrape enough together to get the d700 and 14-24 but I don't want to buy the camera and have a new one come out a few days later. Any advice? Thanks.
