Can't work with mFT TTL passthrough :-(
Hi,
am i too dumb for it?
OM-D, V6 TX on Camera, TTL-Passthrough activated
V6 RX, Flash (FL50 or FL600R) can't be set on TTL...
If the Flash is in the Camara's Hotshoe TTL is activated, but as soon as i remove it only A or M...and it even won't flash manually :-(
Help?
Thx!

While the V6 does not transmit TTL information wirelessly, The TTL pass-through is designed to pass TTL signal from the camera to flash via the transmitter (TX) and vice versa. It supports Olympus system. With TTL pass-through, the TTL flash behaves as they mounted directly on the camera hotshoe. The V6 will work as a wireless flash commander while supporting all the automatic / TTL feature.
For your info., the V6 can wirelessly remote power of Canon, Nikon and Pentax system flash. However, I'm afraid this cannot apply to Olympus system flash.
I hope this information is helpful. Thank you.
I've tried your setting with Nikon SB-910, Nikon D700 and Cactus RF60. The V6 doesn't transmit to RF60 when TTL pass-through is turned on at the first shoot. So before turning on the TTL pass-through mode, please take a test shoot to the RF60 by pressing the test button on the V6. Once the test shoot is success, switch the V6 to TTL pass-through mode. The SB-900 will be working as it mounted on the camera and the V6 will be able to transmit other RF60s at the same time.
The same solution also apply to other Nikon flashes, such as SB-600.
Our engineering team is working to find a better way to handle this operation. Please stay turned with our firmware updates.
Thank you.
The TTL pass-through allows the flash to work as they are mounted directly on the camera. So, all TTL function can be enable.
Sorry, I don't have OM-D, FL50 and FL600R to test. However, please try this if it can solve the problem.
1. Mount the V6 on the camera's and the flash's hotshoe.
2. Enable the TTL pass-through on V6(TX),
3. turn on the flash and set it at TTL mode
The flash will be able to operate in TTL mode. I hope this is helpful. Please let me know if you have any concern.
Thank you.
You could remote control any such flash from a V6 mounted on your Olympus camera.
If you have Olympus flashes, I believe you can still fire them, but not remote control their power. One way to check whether they would fire on a V6 receiver would be to put them on to another (non-Olympus) camera and see whether they fire. If they do, they don't need more than central pin triggering and will work with the V6 as well.
I assume you are using the V6 in wireless mode. Correct me if I 'm wrong. Just to clarify that the TTL pass-through doesn't work in wireless mode. While the V6 doesn't transmit TTL signal wirelessly, this function is designed to pass TTL signal from camera to flash via that transmitter (Tx) and vice versa. The flash is able to work as it directly mounted directly to the camera.
Please turn off the TTL pass-through in wireless mode and try again.
To prevent unintended firing (or misfiring) or no triggering in TTL passthrough mode, choose any Nikon flash profile for a Nikon flash, Canon flash profile for a Canon flash. For other camera systems, please choose MANUAL FLASH to work with the TTL passthrough mode. Choosing a Canon profile to work with a Nikon flash in TTL passthrough mode could cause unintended triggering.
In case you need to update your V6, please download the firmware updater in below link,

It works for me just as you described.
Unfortunately, I don't have a SB-800 so cannot comment on whether this particular model causes issues.
Have you set the profile of the V6 that is on camera to "Nikon SB-800" while the V6 is in TX mode? For some flash models, it is important to select the right flash profile for TTL pass-through to work correctly. If the "Nikon SB-800" profile does not work, I'd also try the "MANUAL" one.
Up to a certain shutter speed, you should be able to do this by triggering for the "MAIN FLASH", but for higher shutter speeds, you'll have to switch to "FIRST FLASH" and use an appropriate "DELAY" value.
Thank you.

TTL pass-through only applies to a flash mounted on top of a V6 transmitter. The transmitter does not lose the ability to set the power of off-camera flashes.
