The Olympus M.Zuiko 40-150mm f/2.8 Pro is one of the workhorse Olympus / OM System lenses, and for good reason – it's a lens I simply cannot be without. I'm lucky enough to have used this lens around the world, both on paid commissions and for personal work, and it's an absolute kitbag essential.
The focal range of the Olympus M.Zuiko 40-150mm f/2.8 Pro is unfamiliar, due to the 2x crop factor of Micro Four Thirds (MFT) cameras, but this is effectively a 70-200mm f/2.8 trinity lens. Except, of course, that said crop factor actually makes this an 80-300mm trinity lens, in a form factor that's smaller and lighter than any full-frame equivalent.
