Versatile Flash Triggering Methods

The YN685EX-RF offers multiple flash triggering options including on-camera flash, radio transmission (master or slave), optical triggering (S1, S2), and PC sync cable connection. This versatility ensures compatibility with a wide range of flash units and lighting setups.

Optical Flash Triggering Compatibility

It can operate as a slave unit with other flashes such as Yongnuo YN320EX or Sony HVL series (HVL-F32M, HVL-F60RM, HVL-F60M), supporting manual optical triggering modes S1 and S2 for broad compatibility.

Advanced Flash Features

The flash supports TTL automatic power adjustment and HSS for shooting at shutter speeds up to 1/8000 s, ideal for variable lighting conditions. First and second curtain sync modes enable creative effects such as motion blur trails either in front of or behind moving subjects.

Radio Frequency Triggering System

The built-in Yongnuo RF system allows wireless control of up to 5 groups of flashes across 16 channels with a range of up to 100 meters. This enables complex lighting setups with reliable remote triggering beyond the line-of-sight limitations of optical triggers.

Ergonomic Design and Operation

The flash head tilts from -7° to 90° vertically and rotates 180° horizontally in each direction. The zoom head covers focal lengths from 20 to 200 mm with manual adjustment. The backlit LCD screen and large buttons provide intuitive control, while optional audio signals inform the user of device status.

Efficient Power Supply

Powered by four standard AA batteries, the YN685EX-RF offers between 100 and 1500 flashes depending on power level. The fast recycle time of approximately 2 seconds minimizes downtime between shots. An external power supply socket allows connection to a battery pack for extended use. Energy-saving mode automatically powers down the unit after inactivity.
