Round Head Flash for Sony

The Flashpoint Zoom Li-Ion X PRO R2 is a round-head speedlight built for Sony camera systems. It provides TTL automatic exposure and an integrated R2 radio system for wireless master or slave control. Photographers who prefer a circular flash spread for softer, more natural-looking light will find this design suits portrait and event work. It is not for shooters who need a rectangular Fresnel head for long-throw coverage or a built-in sub-flash unit.

Lithium-Ion Power and Output Range

A 7.2V 2980mAh lithium-ion battery delivers up to 500 full-power flashes per charge. Power is adjustable from 1/1 down to 1/256 across 81 discrete steps, giving fine control over illumination. Recycle time is approximately 1.5 seconds, supporting continuous shooting at moderate pace. Photographers who require faster recycle speeds for high-volume burst sequences or significantly more total flashes per session will need a different power solution.

Thermal and Operational Behaviour

The internal lithium-ion pack manages heat during repeated firing, with a full-power recycle of about 1.3 seconds indicating efficient energy conversion. Normal use produces typical speedlight warmth without audible fan noise, as the unit relies on passive cooling. There is no external power port for extended high-output sessions. Users who plan sustained maximum-power bursts over long periods should expect thermal throttling to protect the battery and electronics.

Questions about this item

Will the round head and 7.2 V lithium-ion battery work with my Sony a7 III hot shoe?

Yes, the round-head speedlight is built for Sony TTL and slides directly onto the a7 III hot shoe, drawing power from its internal 7.2 V / 2980 mAh pack for up to 500 full-power flashes.

How can I confirm the 1.3 s recycle and 81 power steps are active after mounting?

Fire a test burst; the LCD shows each 1/1 to 1/256 step and the ready lamp glows roughly 1.3 seconds after a full-power pop, confirming the rated recycle speed.

Does the box include the lithium-ion battery and charger, or must I buy them separately?

The 7.2 V / 2980 mAh battery is built into the flash and the package supplies the matching charger, so no separate power purchase is required.
