Is the olympus m zuiko 45mm f 1 8 worth it?

Yes, if you want a portrait lens on Micro Four Thirds. It's small and cheap, and it frames like a 90mm lens on full frame, a flattering distance for faces. At f/1.8 it gives roughly the depth of field of f/3.6 on this sensor, so backgrounds still soften nicely.

It isn't stabilised, so keep your shutter speed up for handheld portraits. It fits plenty of bodies, including the OM System OM-1 Mark II and the OM System OM-5 Mark II. If you shoot in bad weather a lot, the Olympus M.Zuiko 45mm f/1.2 PRO is the weather-sealed step up, and it costs more. For the wider picture on portrait lenses, see Portraits.
