First time poster, long-time reader.

I'm a hobby photographer on a finite budget.
I just received my R5 and am looking for advise on a non-IS EF 70-200, either a f/2.8 or f/4.
Will they benefit from the IBIS capabilities on an R5?
Should I expect similar improvement with an IBIS equipped camera as I would with an IS-equipped lens and no-IBIS in my camera?

Thanks, Duppie
