Olympus recently provided a major firmware update to the E-M1 Mark II, their flagship camera. As part of that update they have included built-in fisheye compensation for the m.Zuiko 8mm f/1.8 PRO. I'm a real fan of this lens, using it quite regularly for landscape and astrophotography. Whenever I pick it up I recognize that I am going to have to deal with the obvious distortion that comes with a fisheye lens. Well, now I don't have to.
The new compensation feature helps turn the 8mm lens from a typical fisheye lens into a rectilinear one. When engaged, the fisheye compensation generates a full resolution jpeg image that emulates a rectilinear lens. As such, two images are recorded, the corrected jpeg, and the original, uncorrected RAW file.
