Best portrait lens for the olympus om d e m5 mark ii?
For portraits on the E-M5 Mark II, I'd look at the 42-45mm primes, which frame like 85mm on full frame. The classic portrait length is a good match for this body.
- Panasonic Leica DG 42.5mm f/1.2: the fastest of the bunch, with the most subject separation and the nicest blur.
- Olympus M.Zuiko 45mm f/1.2 PRO: a pro-grade alternative at the same speed, built to match the body.
- Olympus M.Zuiko 45mm f/1.8: a lighter, easier-to-carry choice that still gives a flattering portrait look.
Whichever you pick, the portraits guide makes the point that light matters more than the lens. Face a window, and expose for the face. For the wider picture on starter lenses, see your first lenses.
