Create light around your subject or augment existing light with the VS-570F Wireless TTL Flash from Bolt. Available here to be fully compatible with Fujifilm's TTL, including use as a wireless slave flash, the VS-570F allows photographers to work quickly and comfortably by knowing that settings can be easily determined with the camera's automatic metering system. This unit also has good power output with a guide number of 141' at ISO 100 and 50mm and can cover a range of focal lengths from 24-105mm using the zoom head, or as wide as 18mm with the pull-out diffusion panel. You can even control output manually with power settings from 1/1 to 1/64.
In addition to on-camera TTL, the VS-570F can be set up as a simple optical slave. Multiple sync modes are available for complete control over your images, including high-speed sync and both 1st and 2nd curtain sync settings. The flash also has a recycle time of 0.5-9 seconds and can run on either 4 AA batteries or an external power pack, thanks to the inclusion of an HV power port. Additionally, for basic off-camera use it has a standard PC sync terminal.
