TrueBlue

High DR and a distortion free wide angle lens are essential. Architectural work will be locked off on tripod or slider so ibis not as important. Best architectural works I have seen are all shot on RED, where the DR really shows up and makes an enormous difference especially on interiors. If more budget, I would look at something like an a6500 with slog and Samyang 12mm f/2.0. NX1 and Samyang 12mm is a nice combo as well if you stick with mostly exteriors. If you really want to get creative, quicklapse using a slider and camera with fully electronic shutter. Surprised I haven't seen the below technique repeated, quality is still the best I've seen across multiple techniques and formats.
