Pentax TTL speedlight with R2 radio

The Flashpoint Zoom Li-on III R2 is a Pentax-dedicated TTL speedlight that integrates an R2 radio transceiver. It delivers a guide number of 197ft / 60m at ISO 100 with the 200mm zoom setting. The unit runs on an interchangeable 7.2V 2600mAh lithium-ion polymer battery.

Replaces AA-powered flashes for faster recycling

This model replaces conventional AA-battery speedlights when recycle speed and shot count matter. Full-power recycle is under 1.5 seconds and a single charge yields approximately 450 full-power flashes. The jump is worth it for event or portrait sessions that demand rapid, sustained bursts without battery swaps.

R2 transmitter or receiver in multi-brand setups

The built-in R2 system lets the flash operate as a transmitter or receiver for Pentax TTL, including exposure compensation, EXIF data, flash value lock and High Speed Sync. Auto-sensing receiver modes also accept Canon, Nikon, Sony, Panasonic, Olympus and Fujifilm TTL signals. A Quick Switch function toggles between Manual and TTL with TCM for on-the-fly control.

Questions about this item

What size hot-shoe foot does the Flashpoint Zoom Li-on III R2 TTL Speedlight need to mount on my Pentax camera?

It uses a standard ISO hot-shoe foot that fits directly onto any Pentax camera with a compatible hot-shoe mount.

How do I set up the Flashpoint Zoom Li-on III R2 TTL Speedlight for wireless Pentax TTL, and what step is often missed?

Insert the charged 7.2V 2600mAh Li-ion battery, power the unit on, then set it to R2 Transmitter or Receiver mode; the step often missed is matching the same radio channel and group on both the flash and any off-camera receivers.

When will the 7.2V 2600mAh Li-ion battery pack need replacing in the Flashpoint Zoom Li-on III R2 TTL Speedlight?

The pack is interchangeable, so you can swap in a fresh 7.2V 2600mAh unit whenever the 450 full-power flashes per charge drops noticeably.
