D800 Does Architecture Impressively! (20mm f/2.8 + 50mm 1.8)

.

My wide-angle lens right now is the 20mm f/2.8D, which I love for it's size and center sharpness on my D700. Yesterday I was able to go on a quick walkabout through some cityscape for a D800 + 20mm trial.

Initial conclusion: Flare, CA on backlit edges can be a problem, mustache distortion as well - but the distortion seems to be handled fairly well by the 20's shipped lens profile in LR 4. Sharpness is very good at f/8, acceptable at the very edges, although I would love to compare it directly to a 14-24 2.8, 16-35 4, 17-35 2.8 or Zeiss 21 - none of which I have. And of course, I find the detail retained by this sensor + lens amazing.

It should be mentioned that the size was extremely nice on this walkabout - the D800 with the 20 mounted fit in to a very small Tamrac Velocity 6x waist bag along with the 50 1.8. This is the bag I use to carry my non-telephoto aps-c combos around, so essentially no size issue here.

Images below, all NEF 12-bit converted in LR 4.1 with some sharpening and slight clarity adjustments on a few, and later some small contrast bumps to retain color in the shots I took after the clouds moved over.
