Olympus has announced new accessories and housings for underwater photography. New to the range is the PT-E03 (waterproof up to a depth of 40m) for the E-400 and the E-410 with Live View, which will be available from June. Live View technology lets underwater photographers use the LCD for framing.
The already waterproof (to 10m) compact 770 SW also gains a housing (waterproof to 40m). More information in the Olympus underwater website.
