The Olympus 75-300 f4.8-5.6 zoom announced a few days ago is another example of the (relative) lightness of m4/3. A 35mm / full-frame equivalent of 150-600mm. The 4/3 format is wonderful if you are a telephoto user. Though not fast, f5.6 for 600mm would be considered very acceptable for many uses. It will be interesting to see some samples.
