The previously rumored Olympus E-M10 Mark IV camera and Olympus M.Zuiko Digital ED 100-400mm f/5.0-6.3 IS lens are now officially announced. I have already posted all specifications and details in previous blog posts. Pre-orders are now open at Adorama and B&H. A hands-on report on the new E-M10 Mark IV can be found here. The full press releases are available here and here.
