Best portrait lens for the olympus om d e m5 mark iii?

For portraits on the E-M5 Mark III, I'd look at the 42-45mm primes. On Micro Four Thirds they frame like 85-90mm on full frame, which is the classic portrait length.

• Olympus M.Zuiko 45mm f/1.2 PRO: my pick if you want the fastest option and the best background blur.
• Panasonic Leica DG 42.5mm f/1.2: a very fast alternative that suits this camera well.
• Panasonic Lumix G 42.5mm f/1.7: a lighter, more affordable way in, and still a lovely portrait lens.

Whichever you choose, the light will matter more than the glass. Read the portraits guide and its light section before you spend much on a lens.
