Use this lens on a E5. I must first send that I have so far only used Leica R lenses with an adapter on the camera. To also times to make snapshots, I put me to this lens as autofocus and image stabilizer. The Leica lenses can only be focused manually, but also with image stabilizer. Because of the outstanding image quality of the Olympus lenses are mentioned here again and again, my expectations were quite high. The result of the image quality was nevertheless more than sobering. I add this comment in 2 shots of the same scene. Both recorded with E5. One with Olympus Zuiko 50-200 in position with 200mm aperture 8, the other with Leica R 280mm also with aperture 8. Between the two lenses are quality default worlds. Therefore there may be for the lens Olympus Zuiko 50-200 maximum a 3. In order to judge the image quality, please consider photos with 200x magnification viewing.
