I sell  EOS Lens Adapters (most are for digital EOS), to use  Leica R,
Nikon, Olympus OM, Pentax 42, and Contax/Yashica lenses.  all are manual
operation, no linkage between the body and lens.  There is even an Exakta
to EOS adapter, but it does not quite focus to infinity.

1) there are at least 4 different manufacturers of the R to EOS adapters.
The Novoflex adapter tends to be a bit tight, sometimes too tight and hard
to remove.  The Chinese and Russian made adapters tend to be of lower
quality, made of aluminum instead of brass. The REOS adapters I sell are
made in Japan, and I believe easier to mount/unmount than the Novoflex.

2) so far, none of my customers have reported any problem to me of uneven
exposures using any of the lens adapters on Digital EOS.  possible causes
of the reported problem discussed here on the LUG  include a camera
malfunction.  another possibility is no problem at all, if it was just
light falloff.   for all the speculation generated, until that camera and
lens setup is tried in combination with other lenses and bodies to narrow
down the problem,  it will be difficult to be SURE of whatever is causing
the reported problem.

3) Canon has  produced many  digital EOS models, so it is difficult to
generalize about all of  them.  to find out how YOUR particular digital
EOS  will operate with a lens adapter, just check your instruction book for
its operation on a bellows.  the operation with that camera and a lens
adapter should be the same,  as neither setup has any linkage to the
shooting lens.
