Canon-EF to Nikon-F conversion ring (EF-lens to F-camera)

This is a conversion you won't find purchasbly on the market due to several reasons:
1. You won't be able to control the aperture of the EF-Lens neither with your Nikon-camera nor manually on the fly.*
2. The flange focal distance of the Nikon F-mount won't allow you to focus to infinity even if the EF-lens is fitted directly to the camera. An additional conversion ring will make it even worse.

So, why designing and printing it anyway? I had to equip a high-speed camera (guess the mount ;)
