A new customer emailed me wanting to know how to attach the speedlight strap and I wondered how many other may have had the same question? So here's your answer Kenneth from illinois! Hopefully the video explains it better than what I had planned to write you back via email.
We get quite a few inquiries a week regarding flash/speedlight compatibility with our beauty dish mount. Before I tell you how to measure your flash for compatibility it's important to know that if you own a Canon or Nikon flash made within last decade it will most likely fit our standard Universal Mount with the exception of some of the smaller speedlights with fixed heads that don't swivel or tilt.
How to measure you flash so we can check compatibility:
1) Measure the width (W) of the widest point of the of the front of the flash head
2) Measure the height (H) which is the thickness of the flash head
3) Measure the depth (D) from the front face of the flash to the body of flash.
Measurements can be given in either mm/inches
