Egami has discovered a new patent filed by Olympus. New patent describes two wide angle, large aperture lenses for Micro Four Thirds system cameras. These are the Olympus 12mm f/1 and 14mm f/1 mft lenses.
These mft lenses could be the world fastest ultra-wide angle autofocus lens for any interchangeable camera system! Aperture f/1 may vary when development of these lenses are finished and become f/1.2. Anyway this is really wonderful news if these patents turn into real products.
See below for the machine translated details for the 12mm f/1 and 14mm f/1 lens patents.
