Flash will not fire on the OM D I mark II. Is there a setting buried in the menus that has to be changed?
Asked by: carole
Do you have batteries installed correctly? Does the unit turn on? When you press the ON/OFF button on the controller, the green light should turn on and the orange Charge light should also turn on if the flash is charged. Also, make sure that the RC Mode in the camera menu (Shooting Menu 2) is OFF.

New to flash here. What is the maximum possible camera to subject distance for adequate illumination?
Asked by: Donna
Twin flashes are not made for covering great distances. They are mainly made for macro photography, extreme close ups of things such as flowers, bugs, and bugs on flowers. As a rough estimate the Olympus STF-8 Twin flash should be fine in a range up to 8-10 feet at the most. If you are looking for more in a distance range up to 40-50 feet, the Olympus FL-900R would be a better option. Please take a look at the following link: https://bhpho.to/2h05lsh

question

Asked by: James W
Just screw the adaptor ring to the front thread of the lens. 2 adaptors of diameters 46 and 62 mm are included in the package. The dia 46 mm ring fits the Oly 60mm macro lens and the 62 mm ring fits the 12-40mm 2.8 and other lenses of the same diameters. If your lens is a different diameter, you will need a step down ring.
