One limit of this table: it lists only Micro Four Thirds lenses that mount natively on the OM System OM-1 — lenses fitted through an adapter are not included here. See which mounts adapt to which.
What these focal lengths actually give you on the OM System OM-1
The OM System OM-1 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.
