Can I use adapted lenses on the om system om 1 mark ii?

I don't cover adapters on this page, so I can't say for sure how adapted lenses behave on the OM-1 Mark II. What I can tell you is that the camera uses the Micro Four Thirds mount, and the lens list on its OM System OM-1 Mark II page is full of native options. If you want a lens that fits without an adapter, start there. For the bigger question of whether a mount will still have the lenses you want in a couple of years, the three questions on the home page are a good place to begin.
