The VS-510P Wireless TTL Shoe Mount Flash from Bolt is a dedicated TTL flash for use with Pentax & Samsung DSLR, mirrorless or point-and-shoot cameras. The VS-510 features a guide number of 141' at ISO 100 and an adjustable tilt head with five positions: 0 to 90°. You can also twist it to the left up to 120° and to the right up to 180°. It covers a 24-105mm range (in 35mm full frame format) and also offers rear curtain synchronization for shooting at slower shutter speeds. The included stand allows you to set the flash up on a flat surface, or to attach it to a tripod head, light stand, or clamp that has a standard 1/4"-20 mount.
The VS-510 has an autofocus assist for low-light photography, and an automatic power-saving function that turns the flash off when it's inactive. It is powered by four AA batteries (not included), with a flash duration between 1/1000 and 1/20,000 of a second. The flash supports high-speed sync up to a quick 1/8000 sec for shooting outdoors at wide apertures and fast shutter speeds. It also has rear-curtain sync.
