Sony-compatible TTL flash with 2.4 GHz wireless

The Flashpoint Zoom Li-on R2 TTL is an on-camera speedlight built for Sony shooters who need reliable wireless control and fast recycling. It integrates the R2 radio system for remote power adjustment and group management up to 100 meters. A built-in 11.1 V 2000 mAh lithium-ion battery delivers 1.5 second recycle times and 650 full-power flashes per charge. The unit supports 1/8000 high-speed sync for bright ambient conditions.

Hot-shoe mount with LCD menu navigation

Installation is a standard hot-shoe attachment followed by channel and group selection on the rear LCD panel. The R2 radio link pairs with compatible triggers or master units without optical line-of-sight. Common issues include forgetting to match channel and group IDs across devices, which prevents firing, and leaving high-speed sync disabled when shutter speeds exceed the camera’s native sync limit. Firmware updates via USB can resolve occasional communication glitches.

2.4 GHz radio range and recycle ceiling

The 2.4 GHz signal reaches roughly 100 meters in open space but walls and RF congestion reduce reliable distance. At full power the capacitor needs 1.5 seconds to recharge, so rapid bursts will slow down after the first few frames. The 650 full-pop rating assumes fresh cells and moderate temperatures; cold weather or aged batteries lower that count. High-speed sync at 1/8000 cuts flash output significantly, limiting effective subject distance.
