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

I needed a white lens to replace the whale one that comes with the Olympus OM-D E-M5 Mark II, I chose it for videography, I understood that ideally I need to buy 3-5 lenses for each situation, but since I’m new to this business, and I don’t have such a budget to buy so many lenses, settled on 12-40mm. What made me very happy is the pro series, the material is iron, it’s nice to hold, and of course the protection against dust and moisture which the carcass itself has, so far there are no complaints, the aperture ratio is at the level
