None whatsoever. I have the PL 8-18, the PL 25, and the PL 100-400. All of them work flawlessly with my E-M5.3.I am looking at the Oly mark III body. Are there any issues with PL lenses? I have tried searching and can’t find much so maybe no issues? Use with teleconverters also? Focus speed? Anything else? Thanks for your help.
