1.Philosophie: In times when full-format cameras are barely larger than a OM-D is especially important for Olympus and Panasonic, to score points where they are unbeatable in size, better compactness of their lenses. In this area, Olympus has now set new standards with its 14-42mm zoom. Namely, in two respects: a. With a length of 22.5 mm, it is the most compact zoom lens of a camera system and b. The automatic lens cover has drawn level with regard to rapid operational readiness with the compact 2. Operation: The lens features a high-grip bezel to manually adjust the distance and a wider, fluted ring for zooming. The advantage over the Panasonic 12-32 is the fact that the lens must be manually deployed not, but that this is done automatically when the camera. Video lovers will also appreciate the ability to customize the zooming by motor jerking. 3. Technical Services: The aperture range is congruent with comparable lenses (Pana Pana 12-32 and 14-42) in 1: 3,5 - 5-6. Who wants more intense zooms who must adapt to bulky lenses. With regard to the focal range it begins unfortunately only at 14 = 28 mm. That's a significant difference to those M43 lenses that start at 12 = 24 mm, such as the Pana 12 - 32. With regard to the image services, so the comparisons have shown with the two aforementioned Panasoniclinsen nearly equal benefits. 4. Conclusion: Anyone who's compact and wants to be quickly ready for use, which is with this lens and its automatic lid certainly served not bad.
