If you want lenses with autofocus with that precious Metabones, then you went into a wrong direction! It is better to have Canon EF lenses. However, if you mainly do manual focus, then it is okay to have Nikon mount. The best thing to do is to return that Metabones Nikon mount to m43 and exchange it with Metabones Canon EF mount to m43. You could always buy Nikon to Canon EF adapter later, but not Canon EF to Nikon.

I am pro nikon and noticed the same thing with the Canon lenses. The autofocus doesn't bother me to much but being able to control aperture is actually very important to me. I would prefer to change the aperture via the dials versus the actual aperture ring. The nikon metabones adapter has numbers on it to tell you roughly what aperture you have but it is not accurate. I have manual AIS/D series lenses so this is really a non issue for me to a certain degree. I really wish there was an adapter that allowed me to use my G series lenses whilst controlling the aperture via the dials on a Panasonic/Sony body. Although I really like the older AIS and D series lenses the newer G series lenses from Nikon, Tamron, Sigma etc provide better contrast with less lens flare. So for certain situations say shooting a high key scene I would prefer to use newer lenses.
