A few thoughts :
-don’t take too fast lenses. I know this can be tempting, but with anything below f/2.8 you will have a very shallow depth of field, which is bad for photogrammetry. And in your case you are working on tripod, so I would aim for lenses around f/2.8 to f/4 : this will be lighter (you are going to move your tripod thousand of times) and cheaper. I am usually sticking to f/4 lenses for photogrammetry and try to use them, depending on the focal and lighting conditions at f/5.6 to f/11 (at their best).
-sony hybrids are great cameras. You can take whatever fits in your budget, it will always be a good choice : they are fast, lightweight, have a great lens selection (my favorite on the full frame is the 16-35 f/4 that proved to be a good all-around lens for photogrammetry). Maybe have a look at the A7R2, I know the price dropped recently with the A7R3 and A7R4 on the market (but these ones are not cheap).
-DSLR cameras are usually heavier (and you have some issues with mirrors sometime).
-in your case another quite unusual option could be the Sigma Foveon sensors cameras. I use the Sigma dp0 a lot (this is a “compact” camera <1000$ with the lens included), this is a very wide angle camera (so maybe for small objects this is not the best fit) but this is so sharp. I had incredible results with the right conditions with this camera : tripod, 100 ISO (forget anything above 200 ISO). This is a very uncommon camera : with a lot of pros : image quality, sharpness, cheap, fantastic colors, lightweight. And a lot of cons : you can only work at 100-200 ISO (but 100 is really better), sensitive to flare (with a greenish flare), a bit slow to operate. But this is really an option that can work (and be cheap) in your case. I am also using a SD but it is way heavier and more expensive if you include the lens. But also an option.
