"I want to buy Canon eos glass. So basically all I need to worry about is that I get an adapter with its own aperture ring if I'm using eos lens, correct? Is Novoflex a good adapter?"
Novoflex is a very good adapter - well-made, but pricey. No one who has bought a Novoflex adapter from us has every complained.
But - Novoflex doesn't make a Canon EOS to M43 Adapter. A company called Birger is working on one, but it will be pricey.
For Panasonic M43 we recommend you get Nikon or Zeiss ZF.2 glass, and the Nikon-to-M43 adapter, if you don't want to use native Panasonic lenses.
Nikon makes better lenses than Canon anyways :)
