Olympus is having a ball these days and has released a whole slew of products over the past two days. After releasing some great digicams, the company also announced a four new inter-changeable lenses for Four Thirds System SLRs. The Zuiko Digital ED 12-60mm (24-120mm) F2.8-4.0 SWD is an HG (High-Grade) series 5x telephoto zoom lens, and the ED 50-200mm (100-400mm) F2.8-3.5 SWD is a 4x telephoto zoom version.

"Stunning results, intuitive design and superior reliability anyplace, anytime – these were the demands these cameras had to meet. Our R&D team did an incredible job. The proof – which you can preview here at PMA – is plain to see: D-SLR photography has evolved as a result of the Four Thirds Standard and the E-System. We’re able to do things that aren’t possible according to conventional SLR concepts. So why should professionals have to limit themselves? We have the solution here and will continue to develop technologies that will be incorporated in future models, such as the successor to the E-1, that will deliver the highest reliability and extreme performance,” explains Michael Handa, Executive Managing Director, Olympus Imaging Europe.

Three of the lenses will incorporate the newly-developed, high-speed SWD (Supersonic Wave Drive) auto-focusing system and the e fourth new lens will have extreme telephoto capabilities in an extremely compact form. There is a a 2.0x tele-converter on the horizon too! Here are the lenses:
