Is the olympus m zuiko 14 150mm f 4 5 6 ii good for portraits?

It's a decent lens for portraits, but not a great one. On Micro Four Thirds it frames like 28-300mm on full frame, so the 85-135mm full-frame range that flatters most portraits sits around 43-68mm on your camera, well inside its zoom. The catch is the f/4-5.6 aperture. It gives you less background blur than a faster lens, and it isn't stabilised, so you'll want to keep shutter speeds up.

I'd treat it as a walk-around lens that can do portraits in a pinch. For portraits that really stand out, a faster lens in that focal range will serve you better. The portraits page explains why the lens matters more than the body, and the lenses guide shows how focal lengths translate between formats.
