Today, Olympus is officially announcing their 8mm f1.8 fisheye lens along with their 7-14mm f2.8 PRO lens for the Micro Four Thirds system. Both lenses are tailored to the higher end user and so they also have weather sealing which is fully complete when using the higher end Olympus OMD products.
We knew about these lenses, saw them, and spent significant amounts of time with the a while ago. Tomorrow, we will have our first impressions posts with both lenses. But in the mean time, the tech specs are after the jump.
