2K € for professional photogrammetry

[Vhzn]

Hi,

I've been lurking since some time the blog and the forum. I feel like now the time to take one step further.

I'm a UAV photogrammetry worker, and i have some futur work for interior modelisation.

So i am looking to gear up and change my old 600D (yeah i know). I have some budget: 2K € for camera and lens.

My first choice:
Sony a7R II ILCE-7RM2
This will let me 600€ for a good fixed lens.

If any photogrammetry expert have some thoughts about this choice, i will appreciated it !
