What these focal lengths actually give you on the OM System OM-5

The OM System OM-5 has a Micro Four Thirds sensor, so it sees a 2× crop of what each lens projects. Every focal length below therefore frames 2× tighter than its marked number. That works in your favour here: the OM System M.Zuiko 150-600mm f/5-6.3 IS reaches 1200mm of effective reach, which on a full-frame body would need a longer, heavier and far more expensive lens.

Effective focal lengths are the marked focal length × the 2× sensor crop factor — the field of view, not a change in the lens itself. Aperture and depth of field are unaffected.
