Old business. New business.

The following quick-and-dirty photograph shows an array of gear used for off-camera flash photography, including a Canon 580EX II Speedlite, Godox X1R-C radio receiver for Canon, Godox X2TF radio transmitter, and Godox X2To/p radio transmitter. This photo will be used to illustrate some old- and new business.

An array of gear used for off-camera flash photography.

Old business

In my last blog post, entitled Pass-through hot shoe, I wrote…

…the Canon macro flash is compatible with Panasonic bridge cameras with one caveat: TTL is incompatible, so it’s manual mode flash only.

Look closely at the Godox X2T-series of radio flash triggers shown in the lower-half of the preceding photo. Notice the pass-through hot shoe on top of both units features one pin — the power pin. Therefore the X2Tx units can be used to trigger a flash mounted on the pass-through hot shoe but no other communication is possible between the camera, X2Tx, and shoe-mounted flash.

When a Canon flash is mounted directly on the hot shoe of one of my Panasonic superzoom bridge cameras, or one of my Fujifilm X-series cameras, the center power pin on the flash and contact on the camera are aligned so the flash can be triggered in manual mode. The other pins on a Canon flash might touch some of the contacts on the cameras, but the pins/contacts aren’t used for the same purpose from one brand to another so they don’t work. As a result, flash features like TTL and high-speed sync might not work. Essentially, it’s as if the camera hot shoe has only one pin — the center power pin.

Ignore the fact that this video was made for the Godox X1T-series radio flash triggers — the X1T and X2T are essentially the same. Fast-forward to 3:03/7:10 for a segment related to mounting a flash on the pass-through hot shoe; the segment ends at 4:00/7:10.

New business (What’s old is new.)

The first two external flash units that I bought are Canon Speedlites, including the Canon 580EX and Canon 580EX II. Neither flash unit is radio-capable — they can be used off-camera but it’s optical master and optical slave mode only for these two flashes. Both Canon flashes cost ~$500 each when new. Although I bought the flash units lightly-used, they hadn’t depreciated much, and as a result, I paid several hundred dollars for each one.

During the past year-or-so, I switched to the Godox TT685-series of external flash units. Not only does each Godox flash cost approximately one-fifth the MSRP for current Canon flashes, the Godox units are radio-capable.

Mounting my Canon 580EX II Speedlite on a Godox X1R-C radio receiver converts the Canon flash to a radio-controlled flash unit that works like any Godox TT685-series flash. Interfaced with an X1R-C, the Canon can be set and triggered remotely by radio from both the Godox X2T-series and XPro-series radio flash triggers, or even another Godox TT685-series flash set for master mode.

The Canon 580EX II — the newer model of my Canon flashes — is fully-compatible with the Godox X1R-C; the older Canon 580EX is incompatible.

For $40 — less than half the cost of a new Godox flash — I was able to repurpose one of my old, reliable Canon flashes. How cool is that? Very cool!

  • Godox X1R-C receiver (enables use of newer Canon flashes with Godox system)
  • cross-brand compatibility among Godox flashes and radio flash triggers
  • TCM Function, Godox XPro-series radio flash triggers
