It’s a bit ironic, perhaps, that on the day I pick up a Sony α7II to embark on a new project, Olympus and Panasonic push the Micro 4/3 world forward with two massive telephoto lenses.

Today, Panasonic announced the Lumix Leica Vario-Elmar 100-400mm lens. The lens isn’t big at all considering the focal range, and comes entirely weather-proofed for all your outdoor needs. Aperture ranges from f/4.0 to f/6.3 at its longest focal length, so three-dimensional action shots should be a breeze at 400mm. And I mean, come on, 100mm to 400mm (or 200mm to 800mm in full-frame speak) in a lens that’s only a third of the size of a full-frame chunk of glass? Now that’s impressive.

Not to be outdone, Olympus also announced their long awaited super telephoto PRO lens today. The 300mm f/4.0 PRO is a super telephoto dream. Like the Vario-Elmar 100mm-400mm, the 300mm f/4.0 PRO is only a fraction of the size of a similar full-frame lens, yet delivers some of the sharpest images in the world at the 600mm focal length. Like all other PRO lenses, the 300mm f/4.0 PRO is weather-proofed and comes with Olympus’ awesome manual focus clutch. Combine this baby with the upcoming OM-D E-M1 Mark II, and I bet some sports and bird photographers will be willing to make the switch.
