Chris thank for the update. Your architectural work is amaizing.
The D800 is a magnificent camera. It feels more that a typical 35 would do, is bulkier and I like that. The detail is incredible even though I don't own the E version. With a fine processing and sharpening you get very good results.
Things about it: you need the best lenses you can get, F/8 best.
What would I change? The live View and the program functions.
Actually Simon Harper help me to the Horseman and the Rodenstock lenses. This is small, light and great combo.
