Olympus recently has filed a 24mm f/1.4 full frame mirrorless lens patent. Olympus 28mm f/2 and Olympus 35mm f/1.4 are the two lens that already filed by Olympus and now with this lens patent, one thing is looking a bit clear that Olympus may announce a new full frame mirrorless camera in very near future (Photokina in September 2016?) .
