The Photokina tradeshow takes place every two years in Cologne, Germany. The 2004 show will be held from September 28 to October 3. Traditionally, camera and other photography equipment manufacturers make some of their biggest product introductions at Photokina. Look forward to new product announcements by Canon, Nikon, Olympus, Pentax, Leica and all the other big photographic manufacturers.
