Advice on Lens mount adapter Nikon to Canon EF?

I'm looking for an adapter to fit AI/AIS lens, i come across different names on adapter.
two of them says Nikon AI to Canon EOS
the other says Nikon F mount to Canon EOS
my question is, are two of them actually different kind of mount or the same?
and if you can recommend a brand that does this well, i would really appreciate it.
i found Fotodiox and Pixco, what you think?

please don't recommend me to stick with canon EF lenses. I want to play around with different lens.

Any Nikon lens that you adapt to a Canon body will have no electronic connection and will be fully manual. If the Nikon lens is the kind that has an aperture ring, you can adjust aperture with that. Nikon G-type lenses have no aperture ring, normally relying on electronic control. With a simple adapter the aperture will stop to the highest f number. There are some adapters that have a mechanical switch that can acquire the iris control lever in the lens and give you mechanical control of the aperture of the G lens.

All Nikon SLR/DSLR lenses are F-Mount.

AI lenses have an aperture indexer (hence the name AI) that won't probably make much difference on a Canon.

However, realize that whenever you use lens adapters, you lose a lot. Not only all advanced functionality (which requires you to use manual exposure and focus), but also the lens won't focus to infinity.

The issue is the "focal plane to flange" distance - the distance from the lens mounting flange to the sensor.

On Canon cameras (virtually all lens types), this distance is 44mm. On Nikon lenses, it is 46.5mm. This means that a Nikon lens is already too long to work properly with a Canon camera. And when you add the extra length required for the adapter, you are extending the length even further.

There are only two possible ways to correct this. First, if the adapter has no internal focusing lens, then the result is as if you put a close-up tube on your lens - which gives you macro capability, but loss of distant focus (focus at infinity).

If the lens has a focusing lens, then there's certainly going to be at least some mismatch, which will result in loss of sharpness of the lens.

This is why you never see these adapters made by the camera manufacturers as they are marginal at best, and any accomplished photographer would never use them.

You also have to realize that there's a huge aftermarket in 3rd party photography gadgets; some that work, and many more that are worthless. Lens adapters are on the latter side of that.

However, if you are prone to try this - I have found that some Fotodiox products are made remarkably well - for your average cheap made-in-China junk.

I'm guessing here (because I'm not a Nikonian). I think both are F-mount but AI has the prong for aperture readout.

My advice? Don't. If you want to play around with lenses, you may be better off with the older M42 mount. It had a more universal scope during its time and adapters to it are far simpler and straightforward meaning not much of the optics and controls are affected which further means you will have to do everything manually.
