Olympus OM-D E-M5 9FPS with 4/3 lens and adapter
How to get the usual 9FPS with an older 4/3 lens and adapter - zoom past 23mm!
Not sure if this is a bug with the firmware (both lens and body at latest) but when you change focal length the camera changes the frames per second.
The switch happens between 23-25mm focal length.
The lens in use is the Olympus Zuiko 14-54mm f/2.8-3.5 lens from the legacy 4/3 system (NOT Micro 4/3). Using the lens on a Mk1 OM-D E-M5 and Viltrox adapter.
