The detachable Olympus VF-2 Electronic Viewfinder mounts to the accessory shoe and hot shoe on Olympus E-P3. The viewfinder with 100% coverage and 1.15x magnification shows you how the subject you are shooting will look under the chosen exposure settings. With a resolution of 1440k dots and a 60fps refresh rate, the viewfinder will give you nearly as sharp a view as an optical viewfinder. The VF-2 rotates up 90 degrees which is useful when shooting subjects from challenging angles. Its diopter can be adjusted to allow most photographers to see subjects in perfect focus without wearing glasses.
