Universal digital slave flash for studio setups

The Ultimaxx UMD-SF100 is a studio-series flash unit designed to fire automatically when it detects another flash. It suits photographers who need an affordable, lightweight fill or background light that integrates with existing manual or TTL master units without extra cables or radio triggers.

Behaviour under sustained studio use

The flash recycles in approximately six seconds at full power, so output remains consistent during portrait sessions with moderate shot intervals. It is not intended for high-speed bursts or event work where continuous rapid firing would exceed the recycle capability and cause missed exposures.

Questions about this item

How much heat does the Ultimaxx UMD-SF100 produce during all-day studio sessions?

The unit runs cool during extended use because it fires only when triggered by another flash, so there is no continuous lamp or modelling light generating heat.

What camera equipment must I already own to fire this slave flash?

You need a master flash or camera with a built-in flash that emits a visible light pulse; the UMD-SF100 optical sensor then triggers instantly.
