Tips on using the Hot Shoe Lock Lever: Be Gentle

Over the past few months I have received occassional reports of V6 units getting "stucked" on cameras. The cause is the plastic spring mechanims holding the locking pin has aged and broke, leaving the the locking pin permanently in the dropped position.

I would like to take this opportunity to recommend all V6 users to:

Not push the Hot Shoe Lock Lever with too much force
.

A gentle slide over of the Lever would just be fine. Stop pushing the Lever as you feel it touches the camera's hot shoe.

Maybe it's better to think of the Lever as a sliding switch to engage the locking pin, and not as a real clamping lock. 

In reality, what stops the V6 from sliding off the camera is not how hard you clamp it down, but the locking pin that is inserted to your camera's hot shoe.

Locking Tips:
  1. Looking from above, do not push the Lever beyond the 4 o'clock positiion.
  2. Stop pushing the Lever as soon as it is in contact with camera's hot shoe.
  3. Anything close to 3:30 or 3 o'clock you are stressing out the plastic spring mechanism.


Beside having the aged spring ends up breaking apart, before it breaks you may notice the locking pin sticking out more even in the retracted position. So this is a sign that the spring in your V6 has been taking up some stress.


FYI we are looking for ways to strengthen the spring mechanism and hopefully we can beef up the spring. But in the meantime, please be gentle on the Lever. Thank you!

To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "v.103".

For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) and not by X-TTL firmware versions: PEN.A.001 and OLY.A.001.  No schedule has been released yet. 

Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.

Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).

  • I have two units where the metal shoe has broken free from the back end.  I expect it's caused by someone over tightening the lever. The units have lost contact with the trigger connection and won't function in Tx mode. The do work in Rx mode but the weight of the flash causes it to tip forward as the back on the metal shoe is free.

  • Hello @Waring,

    I am not sure if over tightening the lock lever could cause the loose hot shoe. The back screw may have loosen over time with on-camera flash mounted or weight pushing the front end of the trigger down, or the screw simply did not hold up. I suppose the screw is not intact anymore? Please send back to dealer for service.

    Thank you!
