Mainly shoot architecture, what kind of camera and lens to use, choose between Canon and Nikon.

I'm afraid the money for professional building lens LZ is not enough to move the shaft head, especially Nikon.

The price of Nikon PC-E 24mm is around 14000, which is obviously unacceptable to LZ.

Canon 24 has to move the axis near 1LZ, and can only choose a half fuselage equivalent to 38.4 wide angle, and there is basically nothing left.

So I think LZ should choose a wide-angle lens with less distortion and better image quality, and use a mid-range fuselage.

So according to LZ's budget, my recommendation is Nikon D300s (about 7d (9500)+ Sigma10-20 (more than 3000) or original factory12-24 (about 5700) (10-24 7000 is too expensive).
