The Micro Four Thirds system is made for telephoto lenses — but ultra-wide angles are tougher for the smaller system. That’s not stopping Olympus from adding another wide-angle zoom to its line-up, however. The Olympus M.Zuiko Digital ED 8-25mm f4.0 Pro — we’ll call it the Olympus 8-25mm f4 Pro for short — is a 16-50mm equivalent lens wrapped in Pro line features. Unlike the mount’s current M.Zuiko 7-14mm f2.8 Pro, the 8-25mm can accept filters without an adapter.
