OM System 40-150mm F4 Pro Review by Amateur Photographer

40-150mm f/4.0 at BHphoto, Adorama, Amazon. GetOlympus. Calumet DE. Wex UK.

Amateur Photographer tested the lens and concluded:

Overall, then, the 40-150mm f/4 is a fine little lens that neatly fills a gap in the M.Zuiko line-up between the entry-level and f/2.8 Pro zooms that cover the same range. It’s a particularly good match for compact Micro Four Thirds bodies such as the E-M5 Mark III, but is just as good a choice for E-M1/OM-1 users looking to travel light. It would make an excellent companion for either the 12-40mm f/2.8 or 12-45mm f/4.5 standard zooms.
