What do yo want to mount where?
The Q8 ON TOP of the Panasonic?
Or the Q8 and Panasonic with a double sided screw on the two threads?
Or the Q8 on a tripod?
I think it would be extremely top-heavy. As long as the hotshoe is robust, I think it would be ok, temporarily. Long term, I think you damage the hotshoe. I would feel safer mounting it to the tripod mount under the camera, or on a separate flash bracket mounted to the tripod mount.
Good day BLFers. I got 3 Q8 from Banggood US warehouse a couple of days ago. Unfortunately all 3, the o ring will pop out while screwing the body to the head. Approximately 1 in 8 attempts the oring will not pop out. Im thinking of ordering smaller size o ring. I dont know if it s the right remedy. Please need advice. Thank you all.

Is the o-ring in its groove? If so they may have changed the o-ring make, slightly different so it now pops out. Does some silicon grease help?
Yes it helps tremendously with the O-Ring not popping out since it slides in smoothly then, if the silicone grease is applied BELOW the O-Ring and not on the O-Ring itself.
Doing it under the O-Ring makes the turning action much smoother, while doing it on the O-Ring, well, if you can screw a fattened O-Ring, the BLF Q8 will become completely waterproof except for the switch, and if you can’t, well it is problematic.
Yes the O ring is in the groove. They all have grease of some kind. But i did clean the thread and o ring and regreased them on the o ring and under, and also the thread, but it did not help. The o ring felt unusually soft.
Thanks Jozz and Blue for the reply
Maybe not its just maybe im not used to the feel of the bigger o ring. I will try to find slightly smaller o ring and check if it will help. Im just wondering if they change o ring size on my batch of light.
Same thing happens with mine. I’ve reapplied super lube and changed to the additional O-ring provided, but it still binds. I’m currently waiting for the O-rings from fasttech and will see if that helps at all.
The o ring will usually pop out thru groove running parallel to the light. The gooves runs thru the o ring canal. I cant compare it to my group buy Q8 because I misplaced it. By chance if anybody can check if they run thru the o ring canal, please! Thanks

If I understand what you are saying/asking, I can verify that my Q8’s have no grooves running into or thru the “O-ring canal”.

It seems like they should cut the o-ring groove just the tiniest bit deeper. You could probably take a hacksaw blade and gently go around the groove and remove just the tiniest bit. Maybe just removing the black finish is enough. The head only needs to squish the o-ring a tiny bit to form a waterproof seal. I’m guessing it’s squishing it too much.

And the o ring squeeze out thru that groove perpendicular to the o ring. All my 3 Q8 are doing it. Im thinking maybe they use slightly bigger o ring this time. Just my thought Just biught it from BG US warehouse.
Hopefully, it is. If not; I fear the the last resort: hack saw I hate to mutilate a beautiful and perfect light
Mutilate? It is just a poor man’s CNC machine. Lol
Add a little black marker to hide the raw aluminum and you won’t even know. Plus it’s completely covered by the head when together, which is 99.9% of the time.
A needle file might make a smoother cut, but not everyone has them.

All the control modes and functions are focused on a single switch, and I'm worried about how long it will last with a high lifetime of frequent clicks

Hi.
May not be the right place.
Do you think the Q8 is too heavy for a hot shoe mount ?
Got a Panasonic Lumix FZ300 and was wondering if the Q8 would be too much for it.
Well, absolutely not.
The BLF Q8 is actually lighter than the FZ300, even full of 18650s.
So, no problem at all for it.

Hi. I want to mount the Q8 to the flash hotshot on top of a Panasonic Lumix DMC FZ300.
Massive amount of light for night shooting.
I think it would be extremely top-heavy. As long as the hotshoe is robust, I think it would be ok, temporarily. Long term, I think you damage the hotshoe. I would feel safer mounting it to the tripod mount under the camera, or on a separate flash bracket mounted to the tripod mount.
Something like this would be safer.

Strange. It should not feel soft, it should feel rubbery.

Let that hacksaw solution be your very last resort.
Something has changed or is out of whack with yours. None of mine do that.
Is your o-ring in the position shirnask pointed out in his picture??
