Is the olympus m zuiko 8 25mm f 4 pro worth it?

Yes, I think it's worth a look if you want one compact zoom for Micro Four Thirds. At 8-25mm it frames roughly like a 16-50mm on full frame, so it covers everything from wide landscapes and interiors to standard street and documentary shots. The f/4 aperture is modest, but it gives about the depth of field of f/8 on this format, which makes it easy to keep more of a scene sharp. It isn't stabilised and it's a zoom, so it won't match a fast prime in low light.

It fits a long list of bodies. For a current, capable pairing, I'd look at the OM System OM-1 Mark II for demanding work or the OM System OM-5 Mark II for something lighter. For more on how sensor size shapes these choices, see Sensor sizes. The full lens details are on the Olympus M.Zuiko 8-25mm f/4 PRO page.
