Interworking Problems with Olympus camera / flashes

Hello,
I am using the following equipment:
Olympus E-M1 II
Olympus Flash FL-600R
Olympus Flash FL-50R
Now I bought two V6 II and a RF60X in a bundle and started some tests. Prior to the tests I upgraded the camera and the attached lens (12-100 IS Pro) to the latest firmware. Both V6 II got the cactus FW OLY.A.003 and the RF60X the A.08. All batteries in the V6 II and the RF60X were fully loaded eneloops. When changing the setup during my tests all equipment was switched off. Switching on was done in the sequence flash - camera - V6 II. The V6 IIs were set to the respective Olympus flash profiles for each test. And here are my results:

The first tests were performed with Olympus flashes on the camera with one V6 II in between, sitting on the hot shoe to check the TTL passthrough funcionality. The hot shoe lock lever of the V6 II is a little bit shaky, but it works. V6 II was set to TX.
1. Olympus FL-600R:
a) TTL mode on. Focal length of the zoom lens is transmitted to the flash
b) TTL mode is working
c) HSS is working
However, some pictures were under- or overexposed. I am getting more reliable results if the FL-600R is put directly on the cameras hot shoe without a V6 II in between.

2. Olympus FL-50R:
a) TTL mode on. Focal length of the zoom lens is transmitted to the flash
b) TTL mode is not working. The flash does not fire. This is not a connectivity problem. Zoom is transmitted. If I switch TTL mode of on the V6 II then the FL-50R is flashing (but in manual mode only and without automatic zoom control)
c) The same behavior as described in b) was seen in HSS mode. HSS is working, but not with TTL mode on.
This seems to be a serious FW issue.

The next steps were done for testing the wireless remote control of flashes.
1. Olympus FL-600R on top of a V6 II, configured as RX. The second V6 II was sitting on the hot shoe of the camera as TX.
a) The zoom is not transmitted from the lens to the flash
b) TTL is working. However, again sometimes over- or underexposed results
c) HSS is not working. The camera does not even allow me to choose shutter times faster than 1/250s.

2. Olympus FL-600R was exchanged with the FL-50R. With the FL-50R I got the same results as with the FL-600R. It is curious that TTL with the FL-50R is now working if it is remote controlled.

3. Cactus RF60X:
a) The zoom is not transmitted from the lens to the flash
b) Although the displays of the V6 and the RF60 are showing "TTL", TTL is not working. The RF60 is flashing with full power only.
c) HSS setting is possible. Strange, but now the camera allows chosing shorter exposure times. But HSS is not working properly. The upper half of the picture is completely overexposed, the lower half is black.
d) Very annoying: If the RF60X is switched off and on again, the channel number and the radio ID has to be set again. It is not stored like with the V6 II.

Summary: The V6 II and the RF60X are of limited use with all these bugs and sometimes unpredictable behavior. I would say that the FW has alpha status, not even beta. I have not decided yet what to do with this equipment. Maybe I will send it back or I will use it as wireless control for my flashes, but for certain applications in manual mode only.

Regards,
Alfred

  • It might be worth trying to use a different firmware version; potentially an earlier X-TTL version or perhaps even the multi-brand variant (no automatic metering but HSS is supported).
  • @Alfed Thank you for the info.

    The V6 II TX is supposed to be attaching on the camera hot shoe. Swapping the flash on the V6 II TX top on camera or swapping the V6 II TX without turning on the V6 II may cause connection interrupted. That leads to exposure inaccuracy problem that you mentioned. Our engineering team is working on the fix now.
