OM System M.Zuiko Digital ED 40-150mm f/4 PRO vs OM System M.Zuiko Digital ED 90mm F3.5 Macro IS PRO
The bottom line
The OM System M.Zuiko Digital ED 40-150mm f/4 PRO is a zoom (40-150mm) and the OM System M.Zuiko Digital ED 90mm F3.5 Macro IS PRO is a 90mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/3.5 vs f/4) and lighter to carry. Choose flexibility or a fast single focal length.
