Review on OLYMPUS M.Zuiko Digital ED 12-40mm F2.8 Pro Lens: Ultimate Quality for Micro Four Thirds Cameras by Amar Amar ᠌

There is color and light. The picture looks "expensive", unlike budget zooms. Sharp from 2.8 at any focal length, 20 megapixels renders for a sweet soul. High-quality materials, the lens is pleasant to hold in hands. They did not save on the hood and lid either. All-weather - it was not possible to test it in practice, but this is definitely a plus. Fast and accurate autofocus. At 40 mm, it is quite tolerable for an m4 / 3 zoom, it washes the background in portraits, although by definition it is not capable of strong bokeh. The presence of an additional functional button. Mechanical manual focus - simple and straightforward.
