It was meant as a joke, man! Who needs to adapt Nikon lenses, when there are cheaper and equally good, yet shorter FL Canon for exisiting adapters available?

 

And for that price it better is pretty good wide open.

 

But even if the hump is blocking the shift vertically upwards: When do you need in landscape orientation ... alright, You do need 

 

The shift goes in both directtions. I don't know how much of the ± 12 mm are blocked. More shift is needed in portrait orientation, I guess. And if I'd really need the full 12 mm perpendicular to landscape orientation, I would turn the camera upside down and shoot tethered.

 

So another "issue" which needs a lot of bad will to become one in reality. 

And you think I did not get that it was a joke? Doh. I found it funny that you can't even adapt it to Canon DSLRs, a joke within the joke.
