Key Features

• Wireless command of ProMaster 200ST-R Speedlights
• Capable of triggering 15 slave flashes in each of its three groups
• TTL exposure control
• High-speed sync (HSS)
• Flash bracketing and exposure compensation

The SM1S is powered by an internal Li-Ion, rechargeable battery, offering impressive efficiency and longevity.

Moreover, the SM1S can function whilst connected to a charger, ensuring you're never left without power. Let's delve deeper. Imagine your SM1S has been inactive for half a year and you suddenly need to use it intensively for a few days.

By the end of the second day, you notice the battery is dwindling and you hadn't considered charging it. Fear not, a mere two-hour charge will restore it to full capacity. Even better, the SM1S can be used whilst charging.

If a trailing cord to a wall socket isn't practical, simply connect a standard power bank (like the one for your phone) to the SM1S. The USB micro-b to USB-A charging cord is included with the SM1S and can be easily replaced from any local shop, should you leave it behind.

Chances are, you'll already have a few spare from other devices.
