Are the pins on the 600EX RT live in a cold hotshoe?

As I always use my two 600s off camera, with STE3 trigger in radio mode I bought a couple of cold Hotshoe umbrella Holders.
Probably not the right description, but they are metal, fit on a lighting stand and have a clamp for an umbrella.

Then I thought when they are triggered - could the electrical pins on the base of the 600s short on these metal brackets?
Should I tape the inside of the bracket with electrical tape.

I am assuming they will not as the little accessory feet are metal, but just thought I would ask.

Its difficult to see e if they touch due to the weather sealing lip.

Any views welcome. I asked Canon UK who said " uhmmmm interesting point - see your concern - but I don't know - I will check," but they have not got back to me.

I don't know if they are or are not, but I've always just added electrical tape for my own peace of mind.

If the shoe has no electrical contact(s) it is just a flash "shoe". If it has electrical contacts it is a "hotshoe".

Many flash shoes lift the flash foot off the bottom of the shoe and the contacts of the flash foot just dangle in air, but some do not. Remember the flash "foot" goes in the "shoe" (or the "hotshoe"). The part on the flash is not a hotshoe, but a flash foot.

Without a closeup image of your flavor of shoe it would be difficult to determine if this may be an issue or no concern at all. If the contacts just dangle in air that is fine. Air is a far better insulator than about anything.

Enjoy! Lon

I've been using THESE (external link) for years without a problem. Notice the center is cut away which probably means the pins don't touch.

My choice for security and electrical safety is the Frio foot. On both counts the benefit far outweighs the cost. See p.20 of TOYUG - link to pdf in my signature

Looks perfect but there is no hole and clamp for a brolly!

So in summary it sounds like I really have to check nothing is touching!

So far I used the canon supplied little foot, and screwed the light stand into the 1/4" hole underneath but I do need to mount an umbrella!

I'd change them for safety sake to something with a groove cut in so the pins arent touching anything.

These are excellent:

Frios are just replacement cold shoes.

I have a few, and their copies, and don't like them at all. I just much prefer a solid metal pinching cold shoe as seen on the above umbrella swivel.

This is just the shoe... you would still need an umbrella adapter. This simply mounts to the top of the umbrella adapter.

See various umbrella adapters in my signature. In all pictures except the last one, I have the flash mounted to a hotshoe that I purchased from FlashZebra. The last umbrella adapter had a metal shoe that could not be removed from the umbrella adapter.

Certainly, everyone has a preference for everything. That said, Lon may recall that I sent him an email about a year ago regarding hot shoes; prior to me getting a 600EX-RT I was using CyberSync manual triggers with the hotshoes from Flash Zebra...

I was outside shooting some family pictures and had a flash setup on a stand with an umbrella. While shooting I had the gear sandbagged and everything went great. However, when we were all done and I was putting things up, I simply collapsed the umbrella while I was packing other things. Unfortunately, a gust a wind caught the umbrella and tossed the setup to the ground.

When I first ran over to take a look I saw some broken plastic and knew for sure I was going to need a foot replacement for my 580EXII and I was pissed at myself for not taking better precautions. Upon closer inspection, I found that it was the Flash Zebra hotshoe that had broke. So I actually wrote Lon, explaining what had happened, and thanked him for the fact that the hotshoe broke... so that my flash did not. If I were using a metal shoe I know that I would have been replacing the foot of the flash instead.

That said, I'll be sticking to the frio and/or other plastic shoes. In addition to what I said above, I actually prefer their fitment to the metal ones. That's just my preference ;)

Should I tape the inside of the bracket with electrical tape.

One can take the Scotch brand 'Magic Mending' tape and apply it to the hotshoe area to insulate all contacts except the large center contact which triggers. Magic Mending tape is made of DuPont Mylar, which is an excellent insulator although thin so that the foot contacts won't have issue with thicker electrical tape.

HERE (external link) is my preferred way to mount my 600EX-RT with an umbrella or umbrella frame soft box. It fits into a standard umbrella adapter. The flash is held on with the velcro strap. Works like a charm.
I put the strap around the head and leave the head tilted so the display is visible, although upside down.

The Frio replaces the clamp at the top of the umbrella bracket you linked to in post 1. Unscrew the metal clamp and replace with a safe one.
