Olympus M.Zuiko Digital ED 12-45mm f/4 PRO Review
When you search for a high-quality lens for Micro Four Thirds, it’s hard to avoid the PRO series from Olympus (now OM System). And in terms of a standard, midrange zoom, one of the best lenses is the Olympus M.Zuiko Digital ED 12-45mm f/4 PRO. Unlike f/2.8 lenses, the Olympus 12-45mm f/4 fits its useful range of focal lengths (24-90mm full-frame equivalent) into a very light, 254 gram (0.56 pound) package.
