I've got the first prototype EdMika adapters from last night's development for the 7.5mm fisheye and 1. the pictures are very sharp, 2. the rear element does not hit any mirrors including the fat 5D2 one and 3. I love not having to focus. I'm still working on a fine calibration system called an EdJuster

before I release this 7.5 kit since it is critical that the flange focal distance is exactly right since you can't make up for any misalignment with a focus ring. My 5D3 took a hard fall with my 400mm 2.8 lens attached and my sensor is 0.002" too far back and this distance makes the fisheye that is perfect on an undamaged body, visibly less sharp on my hard hit 5D3.
I'll add this EdJuster system to most of my kits after allowing people to fine tune infinity at hard focus ring stop for quick finding, right now to ensure all lens calibrations can be handled I send out my kits thinner than needed giving beyond infinity focusing for most users.
Funnily enough, I just adapted the longest focal length of a Canon lens just last week, the monster that is the FL 1200mm f/11. I was able to use a stock FL 55mm 1.2 EdMika adapter (at least with 2 out of the 3 screw holes for now). So this week expanded the range of available adapters from both ends, 7.5mm-1200mm.

I of course have adapters for more than just these, here are those that are currently shipping:http://www.ebay.ca/sch/ed_mika/m.html?_nkw=&_armrs=1&_from=&_ipg=25&_trksid=p3692
