What makes the lens so special is not only its excellent image quality which we can’t harp on enough, but the size, build quality, and speed in focusing. The Micro Four Thirds system has lenses that you really never want to stop down and that perform at their peak essentially wide open. Not only is that wonderful for many folks, but it is also part of the technicalities. Never before have folks wanted to do this more than with something along the lines of Leica M glass.
With all this said, we can only give the Olympus 12-40mm f2.8 our highest recommendation–and it is every bit deserving of our Editor’s Choice award for best mirrorless camera zoom lens.
