A: Unfortunately, no, it is not. I contacted Olympus America and they state that the diffusers included in the Olympus STF-8 Twin Flash are not available as a separate replacement accessory.

Q: 2. I have the OM-D E-M5 MII and I can't get STF-8 to fire during focus bracketing. Is it not compatible or am I missing a setting?

A: You have to change another setting to get it to flash. I had the same problem until I found the answer in the manual. It still took some effort because the manual was not that clear.Under Menu select 2 Advance Camera Shooting Options , Anti-Shock/Silent , Silent Mode Setting , Flash Mode , Allow .It took me a long time to figure this one out. Be sure to set your flash time long enough for the flash to recharge.Good Luck...Doug

Q: 10. Is the STF-8 compatible with the Pen F , will be using the 60mm f2.8 macro?
