Is the om system m zuiko 40 150mm f 4 pro worth it?

I'd call it worth a look if you want telephoto reach in a small system. On Micro Four Thirds it frames like an 80-300mm on full frame, and f/4 gives about the depth of field of f/8 there, so it's easy to isolate a subject at a distance. The trade-off is that the lens isn't stabilised, so keep your shutter speed up. It fits a long list of bodies, including the OM System OM-1 Mark II, OM System OM-5 Mark II, and Panasonic Lumix G9 II. If you're unsure how a 40-150mm compares with other focal lengths on your sensor, the focal length converter will show you the framing. The Micro Four Thirds mount page lists the rest of the system.
