Bolt VS-570 Overview

Create light around your subject or augment existing light with the VS-570SMI Wireless TTL Flash from Bolt. Available here to be fully compatible with Sony's ADI / P-TTL, including use as a wireless master or slave TTL flash, the VS-570SMI allows photographers to work quickly and comfortably by knowing that settings can be easily determined with the camera's automatic metering system.

You can even control output manually with power settings from 1/1 to 1/64.

In addition to wireless TTL, the VS-570S can be set up as a manual master with an optical pulse that features a range of 33' or 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.

This model is equipped with the Sony Multi Interface Shoe and is not directly compatible with the Sony/Minolta Auto-lock Accessory shoe. Optional adapters are available for compatibility with older camera models.

question

Is this comparable with the Sony A7rii ? Will this work with the radio transmitter that comes with the bare bulb bolt ?
Asked by: Christopher G.
This flash has the Multi-Interface Shoe, which makes it compatible with the Sony A7R II. It will not be compatible with the dedicated radio trigger for the Bolt bare bulb flashes like the VB22.

question

Greetings, just received a new Bolt VS-570N, I'm noticing there are options for additional power supplies, PC sync and Firmware upgrade. Where does one get a cable for such or are there three different cables. Thanks... Kevin
Asked by: Kevin T.
There are 3 different cable connections for 3 different purposes. The power supply allows you to connect a battery pack, allowing you to shoot for longer periods of time without running out of battery, and also gives you a faster recycling time from one shot to another. Check out this battery pack as an example: B&H # BOPP310. The PC sync cord connects from the camera to the flash, (assuming your camera has a PC sync) allowing you to take the flash off the camera. Here is a cable from Impact: B&H # IMPCMPCM6 If your camera does not have a PC sync, you can purchase a flash cable from Vello that allows you to do the same thing. B&H # VEOCSN3Finally, the Firmware upgrade is a USB cable that allows you to connect the flash to the computer for firmware updates that Bolt releases.

This unit can be set up as a wireless master. ...

This unit can be set up as a wireless master. What system can this be a master for? Can it control other Panasonic/Olympus flashes, can it control Canon flashes, etc? For instance, besides this flash, I also own some manual Yongnuo YN560-IV flashes; can they be triggered by Bolt VS-570OP?
Asked by: Ivan
I'm sorry but this flash will only trigger other Bolt 570's.
