Yes , they do fit with an adapter but I am kicking myself because some time ago I sold a whole raft of Olympus lenses( for a song) that I had used with my OMD film camera because they did not fit with the then newly introduced digital Oly system. So I invested in a Canon DSLR system. It was only later that the micro 4/3 system was introduced which can use those lenses. Shucks.
Not sure what you are saying. There were adaptors for all the oly OM lenses to fit the DSLR Oly digitals from the start. I used my Old Oly lenses from my 1972 OM1 camera on my Olympus E-1 Digital, and my Olympus Evolt E-300.
There were adaptors for:
OM Zuiko lenses to 4/3 mount
OM Zuiko lenses to micro 4/3 mount
OM 4/3 Zuiko to micro 4/3
However there were never any mounts that auto focus the old lenses, because Olympus never made any Auto Focus OM SLR lens for 35mm SLR's until the OM-G which was a very short lived and not well accepted camera. Too late in the AF SLR market.
Olympus pretty much used the All In One fixed lens zoom for any Autofocus film camera's in the latter years before the inception of digital.
So all the old OM Oly lenses fitted to EITHER the 4/3, or the micro 4/3 with adaptors are manual focus. They never had AF capability back in the 70's/80's on OM camera bodies, ie OM-1 through OM-4Ti and a few after that.
The focus method on adapted lenses is to put the camera on A for aperture preferred. Focus manually with the largest aperture, stop down and let the camera calculate the shutter speed when ready to shoot. Live View magnification helps on the focus. You can even buy focus screens that offer the old split prism.
But the bottom line is that no old OM Zuiko lenses autofocus on any Olympus digital... 4/3 or micro 4/3, which both use the saem sensor, but a different mount system.
Such action was useful before Olympus/Panasonic developed fast primes for 4/3-m4/3, but is a bit fiddly and slow in the focus department because of poor focus screens for manual focus.
In addition, using the Live View function with it's magnification is pretty much a must to focus those old lenses in Manual Focus.
Also, it's doubtful there is any old glass that is better quality than any of the new Oly/Pana glass, only cheaper. I finally sold all my old Zuiko glass. The good stuff and the crap lenses. They did have some duds, just like CaNikon, Pentax and everybody else.
Here is the range of lenses currently available for Olympus that DO Auto Focus for the most part in the first table on the page:
