Olympus has announced a smaller brother for E-620: the E-600. The few differences: no more backlit button (a pity), less Art Filters (in-camera effects), multi exposure mode (2 shots) and control of aspect mask.
All of this to save around $ 100 on the bigger brother (around $ 600 with kit lens). In my opinion it was not necessary to launch such a similar model.
It will be available from November 2009.
