The "roadster" among compact flashes: small, agile, and fast. Ultra-fast recycling times, very short flash durations, a wide power adjustment range, and an extensive selection of light shapers: the Expert D is the top choice for dynamic photography.
With the optional Power Max L - Hensel’s portable power supply - this is possible even outside the studio.
Includes "freemask" functionality and WiFi remote control via app.
The Hensel Remote App is available as a free download on the following platforms:


Highlights of the Expert D 250 Speed:
A wide power adjustment range spanning 9 f-stops in 1/10-stop increments, rapid recycling times of 0.045s to 0.22s (equivalent to 22–4.5 flashes per second), ultra-short flash durations of 1/4000s to 1/10,000s, and a bright 300W modeling light meet the highest demands.
The Expert D 250 Speed achieves its shortest flash duration of 1/10,000s within the practical power range of 90–32 Ws.
Built-in wireless synchronization and remote control, plus "freemask" (perfect-quality cutouts created during shooting) and WiFi remote capabilities (requires free app).
High color temperature and power output stability; high durability reserves for the electronics and flash tube.
Mains-independent operation when combined with the Power Max L (optional accessory).
Power output is regulated via capacitor switching and voltage control.
The extensive range of light shapers for the EH quick-change system leaves nothing to be desired - whether in the studio or on location. This unit demonstrates its advantages for professional photographers, particularly in dynamic portrait, people, and fashion photography.
The compact, detachable, and adjustable tilt head - featuring an integrated umbrella mount - can be attached to either the top or bottom of the Expert D, offering maximum flexibility (e.g., for use with ceiling rail systems). All of this is housed in a sturdy yet lightweight metal casing and is proudly "Made in Germany."
Supplied without reflector.
