I know the one FLO sell is meant for Canon lenses, however someone has replied on their website that this also works with other brands. Has anyone tried it with a Nikon lens? I'm looking at it but can't find any obvious reasons why it shouldn't as it also has three screws in the back. 

The ZWO adapters just has too much wiggling room for my liking, especially since I'm getting a larger sensor camera.
