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

This is a fun fisheye lens. I have two problems with the lens. First, the micro 4/3 mount seems to be too big. Putting the lens on my camera requires more effort than the lens kit (Olympus OMD-EM10 camera). Second, the focus ring seems to be a bit off. Focusing on "infinity" actually blurs the background a bit. In order to get the sharpest possible image at infinity, I really have to hold the focus ring a little in front of the infinity mark. These two things lead me to suspect that the lens is not manufactured to high quality tolerances. None of these issues affect the performance of the lens, and I'm still happy with it. Once the lens is attached to the camera and I've taken the time to manually focus the image, great photos come out. Once properly focused, the sharpness is better than my Olympus kit lens. I would be much tougher if the lens was more expensive. Being so cheap compared to other lenses in its class can really make a fisheye lens accessible to semi-pro and amateur photographers like me. I think this is a great lens for the money and I would recommend it to friends.
