The Bolt VX-710N TTL Flash for Nikon is a dedicated flash for use with Nikon DSLR, mirrorless or point-and-shoot cameras. The VX-710N features a guide number of 164' at ISO 100 and an adjustable tilt head with six positions: -7 to 90°. The -7° downward tilt allows you to fully illuminate your subject when shooting close-up. You can also twist it to the left up to 90° and to the right up to 180°. It covers a 24-180mm range (in 35mm full frame format) and extends to 18-180mm with the diffuser panel in place. In auto mode the zoom range is stepless: it does not set at 24mm, 35mm, etc, but matches the exact focal length of the zoom lens for optimal lighting. The flash supports rear curtain synchronization for shooting at slower shutter speeds. The VX-710N is equipped with wireless (optical) manual slave function, has an autofocus assist for low-light photography, and an automatic power-saving function that turns the flash off when it's inactive.
It can be powered by four AA batteries (not included) and also a convenient HV port allows you to connect the flash to an external power source, such as the included Bolt Cyclone Batterty Pack, for extended usage and faster recycling. The Bolt Cyclone Battery Pack is a reliable, rechargeable Li-Ion power source that provides up to 500 full power flashes, recycles in approximately one second and can be recharged in two hours using the included AC charger. You can clip the battery pack on your belt or carry it using the included strap. Also included with this kit is the flash cable to connect flash unit to battery pack. The coiled cable measures 28" and stretches to 9.2' when fully extended.
