Photokina 2008: It's finally here and so are we (actually some of us have been here since Saturday). Cologne, Germany is playing host both to the Photokina 'World of Imaging' exhibition and the largest (to date) roving contingent of the dpreview staff. Many of the stands are still being built but we've already managed to post some images live from the stands. Over the next couple of days we'll be posting live from the floor of the show to bring you the highlights of the show without the need for you to elbow excitable Europeans out of the way.
