Alongside the E-3 Olympus has also released four new Zuiko Digital lenses, three of which feature Olympus' Supersonic Wave Drive focus system and splashproofing. Let's kick off with the 12-60 f/2.8-4.0 which offers a 5x 24-120mm equiv. zoom range and 25cm closest focus as well as the aforementioned SWD and weathersealing. Next up is the 50-200 f/2.8-3.5 which Olympus claim is twice as fast to focus as its predecessor thanks to SWD. Splashproofing and a polarizer-friendly lens hood also boost its appeal. No other manufacturer can offer a 28-70 equiv. lens at f/2.0 but the 14-35 f/2.0 is just that - a fast, high quality 'normal' zoom with quiet and swift focus which doesn't mind the occasional soaking. The 70-300 f/4.0-5.6 is a little more humdrum but offers Four Thirds users a 140-600mm field of view in a compact and versatile package. Also announced is a new 2.0x teleconverter - the EC-20. The 12-60, 50-200, 70-300 and EC-20 should be available come November 2007 with the 14-35 following in early 2008.
