The yet only German store accepting preorder on the new Panasonic 100-400mm lens is Cyberport. But they made quite a typo and you would have to pay 5.999 Euro or it. I hope they fix this 🙂
In the meantime the lens got officially announced in Japan (DC.watch). And as leaked yesterday there is also the new CM10 (DC.watch).
