The VS-510S Wireless TTL Shoe Mount Flash from Bolt is a dedicated flash for use with Sony DSLR, mirrorless or point-and-shoot cameras with the Sony/Minolta type shoe. 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.

Note: This version uses the proprietary Sony/Minolta type shoe mount. It is not compatible with newer Sony cameras that use the Multi-Interface Shoe.

This speedlight is fully compatible with Sony's TTL metering.
It also supports wireless TTL controls for multiple units and groups, including 4 channels and 3 groups up to 33' away.
The guide number for this flash is 141' (43 m) at 50mm and ISO 100, and 164' (50 m) at 105mm and ISO 100.
The adjustable five-position flash head can be tilted up 0-90°, left 0-120° and right 0-180°. It has an automatic and manual 24-105mm zoom head.
The 1.8" rear backlit LCD Display allows you to easily make adjustments in low light and clearly see what your flash is set to for accurate readings.
With six different manual power levels you can easily change from full to 1/32 power.
With a built-in autofocus-assist beam you can shoot in low-light conditions, using the beam to aid your camera's AF modes.
This flash supports both high speed and rear-curtain sync for more speed and flash control. It supports high-speed sync up to 1/4000 sec--with cameras that support this speed--for shooting outdoors at wide apertures and fast shutter speeds, helping you to freeze motion better
A built-in reflector allows you to enhance the light coming from your flash and the diffuser softens the light for more flattering shadows and images.
Flash compensation is done in-camera. The flash supports the flash compensation range of the camera
The automatic power-saving function turns the flash off to conserve power, allowing you to shoot longer.

      Comments about Bolt VS-510S Wireless TTL Shoe Mount Flash for Sony Cameras:

      I used this unit extensivley over the Christmas holidays and tested it many times in a variety of circumstances. This is a good unit at a reasonable price. I mounted my Sony A 33 and flash unit on a bracket and connected it with the Vello TTL Off Camera Flash Cord. I took a few face on shots producing good typical face on flash pictures. I took the majority of my shots with bounce flash which produced consistent high quality beautifully lighted pictures 100% of the time. Excellent performance! I experimented with the remote wireless feature and produced beautifully professionally lighted photos about 66% of the time. Its a good feature when you have time to set up your photo. Not totally reliable for quick shots of the children however due to the 66% success rate.

          Comments about Bolt VS-510S Wireless TTL Shoe Mount Flash for Sony Cameras:

          I am a flash photography newb so I didn't want to spend $500+ initially so I settled on the Bolt VS-510S flash for my Sony A37. For the specs, the Bolt VS-510S is not bad at all but it was difficult finding reviews online for any Bolt flash. For a 'learning' flash, it isn't too bad. The TTL function seems to work great when attached to the camera, but like I said I am a newb so the whole flash thing is new to me. I have been having a problem trying to get the flash to go off when using it wirelessly, but it could be the fact that I'm s newb and just haven't figured out which settings to have it on yet (I just got it a couple of days ago and have only been able to play with it a couple of hours so far). I really enjoy the fact that it has an adjustable tilt/swivel head that most flashes around this price range with the Sony shoe do not have. The adjustable tilt head is extremely easy to use and you can change the direction of your flash in an instant. I have also not been able to figure out the high speed sync, but I'm chalking that up to the newbness as well. All in all, I have enjoyed using this flash and hope to finally get a bit more time in my schedule to figure out the wireless and high speed sync soon. Once I have a better understanding of the flash I will post an update if the site allows me to. I hope this review helps anyone looking to get into flash photography and trying to find an inexpensive flash. ^_^
