Fast, reliable, and versatile, the SB-5000 offers unparalleled lighting performance in the field and the studio. Radio signals allow working distances of 30 m and enable complex on- and off-camera setups: now you can work in any environment in which the line of sight is obstructed or an optical signal might be weakened by bright sunlight. The new onboard cooling system allows more than 100 rapid-fire shots to be captured with the flash operating at full power. And for photographers who can’t lose a moment when the story breaks, the light, compact SB-5000 features uncluttered controls for intuitive operation. This item is sold as seen for spares or repair.
