Profoto has announced the new Pro 4 battery pack with flash durations down to 1/25,000 sec, fast recycling (30 flashes per second) and an 11-stop range. The B4 can be connected to the mains and used as a studio generator, although the battery can be fully charged within 45 minutes, the firm claim.
Backlit controls are a welcome addition as is the LED panel for each head which can show flash duration as an option. Price and availability has not yet been confirmed.
