Review on Rokinon FE75MFT-B 7.5mm F3.5 UMC Fisheye Lens for Micro Four Thirds (Olympus & Panasonic) - Black by Chasmod Ray ᠌

The lens is not bad, but I would not put 5. The lens is relatively sharp - but nothing outstanding (when compared with 7-14mm, the difference in sharpness will be noticeable in favor of 7-14) Manulny - I don’t see any special problems for fisheye. the zone of sharpness at an open aperture from 5m is almost infinity. What really kills the picture is the chromaticity - it has a lot of chromaticity both in the center and in the corners. Of course, you can do post-processing - remove chromaticity, but this is a waste of time. Therefore, I sold it after 3 weeks of use, leaving 7-14mm.
