Can I use adapted lenses on the panasonic lumix g95?
I don't cover adapters on this site, so I can't tell you which adapted lenses work well on the Panasonic Lumix G95. What I can say is that the G95 is a Micro Four Thirds camera, and every lens in its catalogue list is a Micro Four Thirds lens. That includes the cheaper third-party options from Voigtländer, Sigma, Laowa, TTArtisan and 7Artisans, so you have plenty to pick from without adapting anything.
If you're after a particular lens, check its own page first, and look at the Micro Four Thirds mount guide to see what the system covers. The G95's in-body stabilisation is also worth remembering, since it's useful with manual lenses. For a full list of what fits, start with the G95 page.
