Camar? First time for me to hear that name.

Most probably not. Your only other option is to use an adapter. It's not worth it.

Attempting to use a lens on a camera with a different mount than the lens is usually problematic if not impossible (depending upon the lens and camera)

Basically if you could find a mount, these things would happen.

* you could not focus on infinity
* all automatic features of the lens and camera would no longer work
* all your photos using that lens will be in the full manual mode and some cameras lightmeters will not meter the light correctly.

My guess is you found this unknown lens brand at a thrift shop for $5 or $10 and you thought, "What the heck, I will see if I can get it to work". It will not so just take it back to where ever you purchased it and maybe someone with a Nikon camera can use the lens

You could probably buy an adapter, but the loss of function would make it more trouble than it's worth.

If you're in the market for a lens, it's best to buy the version that fits your camera from the start (this is the first question a good dealer will ask, and any seller worth his salt will specify the fit of a used lens).

Yes it is possible to get an adapter to fit Nikon mount lenses on a Canon EOS camera.

Yes they will focus to infinity - but manually only. There will be no autofocus (the same is not true if you have Nikon camera trying to fit a Canon EF lens).

Metering is possible with any manual or non-CPU lens on all Canon EOS systems - but it would have to have an aperture ring (not electronically controlled aperture) and the lens will need to have a method to stop it down mechanically such as an A/M switch, metering will be stop down metering only - which means the viewfinder will be dark if you have narrow apertures dialled in. The only automatic mode that will work is aperture priority. Manual mode will obviously still work, and so will your light meter.

To be honest with you, it's probably not worth the effort, unless you really know what you are doing - and lenses with electronic aperture control will be next to useless. I frequently use manual lenses with my Canon EOS cameras, and they work just fine.

Strangely enough, the most problematic manual lenses to use on most EOS cameras (except the EOS M, M2, M3) are old Canon FD mount lenses, which can't focus to infinity unless you buy an adaptor with optics inside to compensate.
