Well, it looks like the announcement wasn’t delayed, after all. Amazon just jumped the gun a little yesterday when they made the listing public early for a brief time. Now, though, it’s official. Panasonic has now officially announced the Leica DG Vario-Summilux 25-50mm f/1.7 ASPH lens for Micro Four Thirds.
According to Panasonic, this lens is “The world’s first telephoto zoom lens that achieves an open f/1.7 over the entire zoom range”, although, a field of view equivalent to 100mm on full-frame is kind of a short telephoto. Still, for things like weddings, events or portraits, it’s a great focal length range with a nice wide aperture.
