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.
For many Olympus shooters a natural question might be, how does the corrected version's field of view compare to the 7mm focal length of the m.Zuiko 7-14mm f/2.8 PRO. The two images below help to illustrate the differences.
Overall, I have been pleased with the results I have gotten from the new built-in fisheye correction, particularly when using Setting 1. I really like the fact that I get both a jpeg and RAW image that I can work with. The jpeg image quality defaults to LN, not the higher quality LF setting so you may want to change this.
Since the images are digitally corrected some camera features are disabled. This includes the following;
- video recording
- all sequential shooting modes
- Live Composite
- Art Filters (Although I don't use the Art Filters too often, I am hoping that in a future update these can be used with the fisheye correction.)
