I found the answer today. For the OLY Pen F, Camera Raw version 9.5 is needed to open raw files. On an Adobe website, I found today, that there are some issues with Mac OS systems and that Adobe is working to resolve these before releasing version 9.5 to LR although it is available for PhotoshopCC (which does read the Pen F raw files).What a bummer considering that the Pen F has been out there for quite some time. So you Pen F owners/buyers beware and be patient. The next question is how to most conveniently transfer opened raw files from Photoshop to LR because LR does have some very efficient post processing that is laborious to do in Photoshop.

I recently bought a new Olympus Pen F and find that LR will not recognize raw files from files taken with that camera. I subscribe to the Adobe Cloud program (monthly subscription so have uptodated Photoshop and LR programs).I was told by OLY that I needed to update my Adobe Raw software -- which I did to version 9.5.1-- but the problem still exists although the raw files are recognized in Photoshop. Adobe shows that the camera is supported by their software in the versions I have. I have other OLY micro 4/3 cameras that do not have that problem.Clues?

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.

After waiting for some weeks for the backordered OM10 to arrive it did and worked well for a few shots then the shots became terribly over exposed and the view finder also showed it before the shot taken . No comparison with the Pen EP 5 which I own Called Oly customer service and was told to return it. I wonder about quality control ( these are built in China)
