Olympus 40-150mm F2.8 Pro Lens Review & Sample Images

My review of this fantastic lens from Olympus with some sample images taken at various focal lengths and apertures with the Olympus OMD EM5 mk1 & mk2 cameras. The lens features a constant F2.8 aperture across the 40-150mm (80-300mm EFL) beautiful manual focus and zoom control. The lens has internal zoom so the lens does not "trombone" as yo extend the zoom. Weatherproof, that is splash and dust proof and protection from freezing down to -10C.
