Can I use adapted lenses on the nikon d750?
I don't cover adapters on this site, so I can't tell you how an adapted lens will behave on the Nikon D750. What I can tell you is that the D750 takes Nikon F mount lenses directly, and its catalogue page lists a lot of them, including third-party options.
If you want something to start with, these are good matches from that list:
- Sigma 35mm f/1.4 DG HSM Art for a fast, versatile standard-wide prime.
- Nikon AF-S 85mm f/1.8G for portraits without a big bill.
- Nikon AF-S 24-70mm f/2.8E ED VR as a do-everything zoom.
