There are a lot of replies here, and as usual they don't answer the question. "You don't wanna do that, do this instead." So here's a sensible answer to your question.
There are four types of Canon lenses commonly available:
EOS for DSLRs and later EOS autofocus film cameras
EOS-M for mirrorless cameras
FD / FL for the older non autofocus cameras
M39 for the old 1950's rangefinders
If you have an EOS lens, it wont have an aperture control (Unless its an odd 3rd party manual lens) but adaptors are available.
If you have an EOS-M, it wont fit and there is no adaptor
There are hundreds of adaptors for FD/FL and M39 lenses
I use adaptors by Neewer, K&F and other non brands. Never had a problem with any of them.
Using other brand lenses means you have to focus manually and set the aperture yourself. Use P or A on your camera. Or M for full manual control. The Fujis have got good focus assist features for using classic lenses like this. Classic lenses have a lot of character and there are millions of them, cheap.
