Choose the OM System M.Zuiko Digital ED 300mm F4 IS PRO if…
- ✓You need more reach — it goes to 300mm vs 150mm for distant subjects, wildlife and sport.
- ✓You prefer a fast, compact single focal length — a 300mm prime over a zoom.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You like close-focus work — 0.48x magnification vs 0.21x.
Choose the OM System M.Zuiko Digital ED 40-150mm F2.8 PRO if…
- ✓You want more light and background blur — f/2.8 is faster than f/4, better for low light and subject separation.
- ✓You shoot wide — it starts at 40mm vs 300mm for landscapes, interiors and architecture.
- ✓You're on a budget — $1,499 vs $2,499 leaves more for other gear.
- ✓You want one-lens flexibility — a 40-150mm zoom covers what the fixed 300mm can't reframe.
