Adapting FD to EF is not an ideal thing to do, due to the
negative difference in the register distance between the two
systems.
FD uses 42mm ... EF uses 44mm ... this means, you have to
hammer the lens about 2mm into the EF-Body (not to think of
the adapter).
There are adapters that use a lens to care of this, but with that,
you inherently lose image quality (they also enlare the focal length
by a factor around 1.3).
There are adapters without lens, which of course don't influence
imagequality, but with those, you lose the ability to focus to infinity.
Adapting on a 4/3-system is easier, since the register distance of
this system is much shorter than the 42mm of FD.
