Jonathan,
thank you for your input.
A couple of thoughts from my end:
-
The aperture on Nikon’s prime lens (35mm/f1.8 or 50mm/f1.8) is adjustable from 1.8 to 16, which I hope is enough.
-
I’m currently designing/building an automated robot arm which moves around the object. So image processing time, handling, and needed amount of photos isn’t really a big thing since it will be almost fully automated (can run overnight)
-
Light also shouldn’t be an issue due to multiple softboxes around the object.
The main question is really, how much affect on the picture quality has the mirror “impact” .
I somehow believe Nikons D750 is better than Sonys A7ii but I’m also not an expert in photogrammetry/photography.
Sony’s A7Rii is nice, but also $300 more expensive. Lenses are probably also more expensive. Is it worth the extra money or does it just squeeze out the last 2%?
Sigmas sd Quattro H camera would also be in my targeted range but does it outperform Nikon’s D750 / Sonys A7ii/A7rii when it comes to photogrammetry?
In regards to the lens, would the wider angle on a 35mm lens perform better or worse than a more straight 50mm lens? Since I’m trying to capture smaller parts or small details on parts, I’m probably getting a makro lens as well.
Thanks,
Thomas
