Can I use adapted lenses on the olympus om d e m1 mark iii?
I don't cover lens adapters on this site, so I can't tell you how an adapted lens will behave on the E-M1 Mark III. The camera takes Micro Four Thirds lenses, and every lens on its catalogue page is listed for that mount.
If you want fast, manual-focus glass without an adapter, look at the Voigtländer Nokton 25mm f/0.95 Type II or the 7Artisans 35mm f/1.4. Both are listed for Micro Four Thirds, so you won't need anything in between.
