I’m not sure if you mean the non-IS version or the original IS version but I have tried the original IS version on the R7 and I get the full 15fps with EFCS. With ES I can only get 15fps, no luck with 30fps. The IS works when you first turn the camera on but when if goes to sleep and wakes back up the IS doesn’t come back on unless I physically turn the IS switch on the lens off then back on which is very annoying. The AF area is also limited to something like 80% which is still quite usable, probably better than any DSLR.

The EF 300mm f2.8 (1st version) predates the IS version. It is my understanding (which may not be correct) is that this early lens was from an era of lesser technology, including simpler algorithms due to lesser processing power.  The lens then does not support upgraded features of later cameras, including improved focusing speed.
