I have a D700 which I'm not planning to replace at this point in Nikon's product cycle. I'll porbably buy the D800's successor. Not because I don't like the D800 (especially its usability improvements around focus mode switching and Live View, which don't seem to have attracted much attention) but because I can't justify the cost when there are too few things the D800 does that the D700 doesn't. Anyway, although I'm keeping the D700 for now, I'm planning to buy a wide-angle prime so that I end up with this in my bag: D700, SB-800, 105mm micro, 50mm, wideangle. I need to choose a wide-angle lens. The 14-24 is a great lens, but too big for me to routinely carry it. So I'm going to buy a wide-angle prime. However, I don't want to buy a prime now that turns out to be disappointing on the replacement body I eventually buy. As for focal length, the 35mm is a lens I could like but it's too close to the 50mm for me to seriously consider buying it. Hence I'm looking at the 20mm - 28mm focal length range. Which Nikon primes have sufficient micro-contrast to work well with bodies with a finer pixel pitch at full frame (I'm going to assume for the sake of the discussion that that is what the D800 successor will be like: FX, high resolution)? I'm going to assume that the 24mm f/1.4 is going to be among the suggestions, and in fact Nikon points it out in the technical guide for the D800 as being suitable for use with the D800E. It's heavy and expensive so I worry that in practice I'd leave it behind with the 14-24. So I'm interested in my other likely options. My planned uses are principally travel photography, interior shots, architecture, some environmental portraits. What do you say?
