RokinonRK12M-M 12mm F2.0 NCS CS Ultra Wide Angle Fixed Lens for Canon EF-M Mount Compact System Cameras (Black)

Well built and a great lens for nighttime photography. Manual focus is easy to use and after a couple of shots working out the infinity position on ring is simple. A great lens at a fantastic price compared to other options

waste of money. don't bother. says it fits but doesn't say it wont do the job. left with a frame on the picture. doesn't mention it wont work on full frame. but at least you had my money for 3 weeks before i found this out.
