Helping to retain Panasonic's reputation as a key player in the photographic industry, is their ability to continue to improve on their existing products, even when the previous model is very successful and not obviously in need of improvement. This new lens, the Lumix 100-300mm f4-5.6 II Power OIS is a fine example of this, a re-imagining of a well received telephoto zoom lens with various improvements to build, performance and compatibility with the dual IS 2 of Panasonic's own GH5 Micro Four Thirds cameras. The long telephoto zoom range that will excite, sports and action photographers remains intact and at the forefront of the feature set.
