Is the om system m zuiko 150 600mm f 5 6 3 is long enough for birds?

Yes. On Micro Four Thirds this lens frames like 300-1200mm on full frame, well past the 600mm equivalent I'd call the minimum for birds. It's stabilised and has autofocus, so you can hand-hold it, which is rare at that reach.

The catch is the aperture. At f/5-6.3 it's dark, especially at the long end, so you'll want good light or a camera that's comfortable at higher ISO. Birds are small in the frame, so you'll also crop a lot, and the Micro Four Thirds sensor helps with that.

If you want a body to pair it with, the OM System OM-1 Mark II or the lighter OM System OM-5 Mark II both fit. For more on reach, see Wildlife and sport, and check buying used to save on a long lens.
