If you get an adapter for an EF mount camera you will probably regret it. The adapters all use glass elements which act as telephoto groups and will change the focal length slightly. Any cheaply made adapter will also add additional distortion as well as aberations... Canon has one out there that they sold for a couple of years that would be the best bet, but it's fairly rare, fairly expensive if you find one, and still not great.
Aaron D. Locke has nailed it - get an adapter. They have some here on Amazon that are available with Prime. Be sure to read the reviews. BTW, I use my husband's old FD lenses from his AE-1 on my micro 4/3 camera, and I'm enjoying them greatly.
