The Panasonic Leica Vario Elmar 100-400mm is a telephoto zoom that keeps amazing me. This telephoto lens focuses fastest, on both an Olympus and on a Panasonic camera, from infinity to 1.5 meters of all the telephoto lenses that we have reviewed. You do not need to stop down this telephoto zoom, because the sharpness at full aperture is already maximum. And that’s a good thing, because telephoto lenses are often used to freeze motion, and you need a short shutter time for that. Thanks to the built-in image stabilization, you have a quiet viewfinder image even when shooting by hand and are less likely to get motion blur in low light. The image stabilization also worked perfectly with the GX80 for video. The robust construction and extra sealing against dust and splashwater make this super-telephoto zoom perfect for use under the most extreme conditions. For a telephoto zoom with which you can bring a subject in so close (the field of view corresponds with an 800mm lens on a camera with a full-frame sensor), this telephoto zoom is unbelievably light, so that you will be happy to take it along on a trip, without it becoming a burden.
