Pre-Photokina 2008: Olympus has today announced the development of a new Four Thirds system DSLR aimed at advanced amateur photographers. The fabled ‘tweener’ is an addition to the range positioned between the E-3 and the E-520 models, and inherits a number of the E-3’s professional-level features including its advanced high-speed 11-point autofocus system, built-in image stabilization system with up to 5 stops correction, and somewhat cryptically ‘a new and updated feature to replace the current splash- and dust-proof function’. Olympus will be exhibiting the camera at Photokina, and it is due to for release in the first quarter of 2009.
