      > It is not exactly straightforward to use the Samyang 7.5mm on a Nex. First the usual M43 to Nex adapters on Ebay are a little too thick so people are removing a couple of spacing rings inside the Samyang to get it to infinity focus on the Nex. Then you need to shave the Samyang to get full circle coverage. Then you have the issue of no remote socket. Reports are also that it needs to be stopped down a lot to make it sharp across the format and there is a rogue reflection which causes grief sometimes. There is a comprehensive discussion here
