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

The picture is luxurious. Sharp over the entire area, fast, with natural colors (if you set the bb correctly, or even set it to auto), aperture, excellent range of focal lengths. It is very reliable to the touch (I did not check for impact resistance :). The zoom ring is tight for me, but it's a matter of habit. Bottom line: a universal pro zoom for all occasions. Pair it with a 25mm prime at f/1.2 or f/1.4 and you'll have a set of lenses for life. For what money Olympus breaks, you can understand, but the toad is strangling. Therefore, to be honest, I took BU.
