Combine the Four-Thirds camera's 2x lens factor and the EC-20 2x teleconverter with the Zuiko 300mm f/2.8 for a hand-holdable, ultra-portable, Image stabilized 1200mm f/5.6 equivalent lens!
Among many a photographer the sensor factor is considered a bad thing. Usually these complaints focus on the wide end of things, where the smaller sensors make wide angle lenses less wide (see related story). But at the telephoto end, it's a different story. A smaller sensor means more effective reach. And among DSLRs, nowhere is this gain more realized than on the 2x factor Four Thirds system.
So, when the Olympus Zuiko 300mm f/2.8 Super Telephoto lens ($5895, street) is mounted on the Olympus E-3, it becomes, in effect, a 600mm f/2.8. Add in the Olympus Zuiko EC-20 2x teleconverter ($479, street), and you've got an effective 1200mm f/5.6 (EXIF data indicates an actual f/5.7 aperture, but this is a negligible difference) sensor-shift stabilized supertelephoto lens that weights just over eight pounds! Add in the E-3 and an HLD-4 vertical grip, and this whole kit weighs in at less than 11 pounds.
