I use lens adapters all the time.
In your case, you will have the same issues I have going from other lenses to a micro 4/3 lens. The adapter, if it does not translate the electronic communications to your lens, well, you'll have to manually focus and set the lens settings as best as you can. For my experience in using adapters to EOS is if the aperture setting is done internal and electronic, your adapter just got expensive.
Let me show you what happened to me in reverse when I got adapters for all my old manual focus lenses, except for the EOS lenses. The cost for an adapter became cost prohibited (link at the end showing the difference in the adapters I have available).
I have been a freelance photographer since 1976, and before digital, I had Nikon F3, Canon AE-1, Olympus OM1, Pentax K-1000, and even a post WWII Exakta (made in the Russian side of Germany).
I kept these cameras for some reason and amassed about 100 lenses, including macros, bellows for them, etc.
Before my disability I shot with heavy Canon digital gear for the Charlotte Sun, Bradenton Herald, NY Post, Getty Images, Minneapolis-Star Tribune, and spent 8 years shooting every Tampa Bay Buccaneers Football games, and many Rays baseball games.
After 3 failed back surgeries and a future hip fusion, I bought two cameras - an Olympus PEN and the OMD-10. The lenses were the same size and just as light as my old lenses I haven't used for 40+ years.
With adapters, I know have use of all my professional Nikon, Canon, Olympus, Exacta, and Promaster lenses I used on my Pentax. There is no quality loss, in fact, I prefer, even though I need to manually focus and set either the shutter speed or the aperture, there is no camera lag in manual focus mode, so I get the photos I am accustomed to.
You do not need to get the expensive ones, each of mine cost about $15 a piece from Amazon.
HOWEVER, one caveat – if you have any EOS lenses you want to use, then you need a special adapter. For these lenses, you cannot set the aperture. So it is always set a f/2.8 or the fastest possible setting for your lens. You can set the shutter speed, but if you want to shoot at f/8 or f/11 or with your wide angle at f/32, you need to get a special adapter.
They have different kinds. The cheapest, that run about $200, have a dial that will allow your to set 5 or 6 different aperture settings and many will allow autofocus to work. Then there are those that are upwards of $500 that will translate the not only the autofocus, but set the aperture correctly.
