"The Japanese website Egami (Click here) found a new Olympus patent describing different variations of a new 150mm f/2.8 macro lens. There are actually two different versions. One shorter lens for the m43 system and a longer lens for the Four Thirds system. Both are described as high quality optics. The only similar lens currently on market is the Sigma 150mm lens"
Ciekawe, ciekawe...
