question

For Canon Powershot cameras, how do you decide 1st curtain sync or 2nd curtain sync, and S1 or S2?
Asked by: paul
The right flash mode would depend on what modes are offered in the camera and the application. If using 1st curtain sync, the flash will fire when the exposure begins while with 2nd curtain sync, the flash will fire just before the exposure ends.

Does it work with the Phottix transmitter, the 15 flash in groups of 3 system?
Asked by: Mark
In order to trigger this flash with any Phottix radio transmitter such as the Odin II, Strato II or Odin Lite, you would need a receiver such as the Phottix Odin II TTL Flash Trigger Receiver for Canon., B&H # PH89072. However, this particular radio trigger system has only been confirmed as compatible with Canon brand flash, so your results may vary when using other brands of Canon compatible flashes.

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.

question

Can I use some cable to shoot with the Bolt VS-570F flash in TTL mode AND off camera? If yes, do you think the HSS will work too? I appreciate your help! (I own an X-T10 and need to shoot off camera in TTL mode; thank you!)
Asked by: R. S.
You wouldn't need an off-camera TTL cable to use this flash TTL off camera - this is a wireless TTL flash featuring slave functionality.
