Olympus VA-1 Overview The VA-1 offers a twin solution for capturing unique shots, enabling focusing to be carried out from virtually any position by offering full size-view and 2x magnification. It is very useful when using telephoto, close-up and macro lenses. The VA-1 fits over the camera's optical viewfinder. Its viewing tube rotates a full 360°, with click-stop positions every 90° for even the most difficult shooting angles. A built-in diopter corrector ring allows adjustments between +3 to -5 diopters. The VA-1 can be attached to the Olympus E-1 as well as to the Olympus E-300 with the supplied adapter rings.
