A new lithium-fuelled aftermarket flash works as a master or a slave in the Canon RT 2.4 GHz system.

Yongnuo YN-686EX-RT

Yongnuo, the Shenzhen-based photographic equipment manufacturer, has announced a new flash for the Canon RT radio transmission system. The Yongnuo Speedlite YN686EX-RT has a built-in 2.4 GHz transceiver, letting photographers control and trigger it wirelessly in combination with the Canon ST-E3-RT, 600EX-RT II, 430EX III-RT and Yongnuo’s aftermarket equivalents.

What’s unique about the YN686EX-RT is it is powered by a 2000 mAh lithium-ion battery, providing up to 750 full-power flashes from a single charge and faster recycle times than AAs (1.5 seconds at full power) without the need to attach an external high-voltage battery pack.

The Yongnuo YN686EX-RT has a guide number of 60 and works as either a master or a slave for the Canon RT system, letting you use E-TTL mode and remotely control power off-camera. The electronic zoom head has a range from 20–200mm and the unit also supports optical slave triggering, stroboscopic mode and high-speed sync.

The Yongnuo YN686EX-RT is available now for $140 (£116) from eBay US and eBay UK.

    No Nikon version?

    • Not for the RT-series flashes. Maybe they’ll release a universal lithium flash in the future.

  • davv

    is it just me or does that battery look very similar to the godox one ?

  • Van Gelis

    will this overheat and die like the YN600? also the weight of the flash with battery is a big factor. If you are doing event photography with on camera flash, u can break the hotshoe with the weight.

    Also, you will have to buy a spare battery and if you look on ebay, they’re not available 🙁

    • I had a quick look and there are a couple of listings that include two YN-B2000 batteries with the flash rather than one. But you are right: I haven’t seen the battery on sale separately anywhere, yet.
