Wireless Shutter Trigger for Fujifilm GFX100S II | Field-Tested by Architectural Photographer

TL;DR:
Yes, you can use a wireless shutter release with the Fujifilm GFX100S II. I tested the PROfezzion Wireless Trigger, and it works—reliably. Just plug it into the shutter release port (not the audio jack), and you’re off to the races. Pro tip: read the manual, save your sanity.

Can I Use a Wireless Trigger with the GFX100S II? Yep. Eventually.

If you read my Leica SL2 remote saga (linked here), you know the routine: obscure forums, outdated posts, and absolutely no straight answers.

When I got the GFX100S II, I was cautiously optimistic. Fujifilm’s XApp is actually decent—smooth interface, wireless control, adjustable settings. It makes you feel like the future is now.

Until you leave the room.

Bluetooth, as it turns out, was designed for photographers shooting self-portraits in lavender fields—not architectural photographers crouching behind drywall with a strobe in one hand and caffeine withdrawals in the other. Once you introduce concrete, distance, or ambition, the signal folds.

The Fix (aka, the Cheapest Victory of the Year)

After the usual pilgrimage through gear forums, I found it: the PROfezzion PR-UN1 Wireless Shutter Release. Not flashy. Not expensive. But it claimed to work with Fujifilm via a 2.5mm jack, using RF instead of Bluetooth.

I ordered it. I plugged it in.

Nothing.

Then I remembered: not the audio jack. Plug it into the actual shutter release port—because this isn’t the Leica SL2 all over again. This one has the port right there, labeled and everything.

I tried again. Pressed the button. Click.

It worked. Not just in line of sight, but through walls, around corners, and inside dense interiors. I tested it from 30+ feet away through concrete. Rock solid.

It gives you all the expected modes—single, bulb, delay, continuous. No video support, but this isn’t for cinema. It’s for those still-life architectural moments when the app just isn’t cutting it.

Final Thoughts

If you’re an architectural, interior, or real estate photographer who shoots solo and needs distance + reliability, this little PROfezzion trigger earns its space in your bag.

Not flashy. Not complicated. But it works—and in this line of work, that’s everything.

Till next time—press the button, and pray it clicks.
