Bolt VC-310C overview

  • 1Description

Compact and very capable, the VC-310C Compact On-Camera TTL Flash from Bolt is fully compatible with Canon's E-TTL / E-TTL II system and offers a plethora of features for advanced on- and off-camera flash photography. The relatively small unit has a guide number of 105' at ISO 100 for easily illuminating a range of subjects as well as coverage for 28mm lenses on full frame cameras or 18mm on APS-C cameras. The included diffuser can soften the output of the flash while increasing the coverage to 17mm on full frame or 12mm on APS-C. For bounce capabilities the VC-310C can tilt from -7 to 90° and rotate left 60° and right 90° for more flattering lighting than provided by direct flash.

Another feature of the VC-310C is the ability to use LED lights to preview lighting and as a focus assist. This model can be used as a wireless master or slave with full TTL support in each mode. Stroboscopic mode is available for creative effects requiring multiple flashes during a single exposure for numerous possibilities. The ability to accept firmware updates via a Micro-USB port ensures compatibility in the rapidly changing digital landscape.

Coverage for 28mm lenses on full frame or 18mm on APS-C, when the diffuser is used it expands coverage to 17mm on full frame or 12mm on APS-C
Manual power settings are available with settings from 1/1 to 1/128
Recycle time of about 5 seconds at full power
Backlit LCD screen
Modeling flash setting will fire a burst of flashes for a preview of lighting
Flash exposure compensation from -3 to +3 EV in 1/3 EV steps
Second curtain sync setting allows flash to fire at the end of exposure for more advanced lighting techniques

    Bolt VC-310C reviews

    VC-310C Compact On-Camera TTL Flash for Canon Cameras is rated 4.3 out of 5 by 15.
    Rated 4 out of 5 by from Good small flash I use this on my Canon G5X compact 1 inch sensor camera. FAR better results than the awful little pop up flash. Results are actually very nice when aimed up at about a 45 degree angle and using the supplied bounce diffuser. It would be nice if the flash would rotate fully to the rear for better bounce, but I suspect it was designed not to because it does not have the power for that type of bounce situation. A good value for the price. Some more power and full bounce ability are the only reasons why I don't rate it 5 stars, but with it's small size and only 2 battery capacity, it's probably doing the best as can be expected. Good value for the money.

    Rated 5 out of 5 by from I would buy this flash again and would recommend it! I own a Canon 600EX, which suit most of my needs, except for when I travel. It size adds to the bulk and weight that I have to contend with when I travel. I was interested in a smaller, lighter strobe for travel. I was surprised to find in the B&H catalogue the Bolt VC310C. It was small, light weight, TTL, LED info bounced, swiveled and interfaced with my Canon EOS. Perfect for my travel needs. So far it has been perfect! I would recommend it to anyone looking for a compact, feature loaded flash for traveling.

    Rated 3 out of 5 by from Powerful, but not accurate This a powerful flash, great for the price. However, the eTTL exposure circuitry doesn’t appear to be very accurate. I consistently get images overexposed by about 1 stop when using the flash in eTTL mode. I am able to compensate for the overexposure by adjusting the flash output down by 1 stop, but that defeats the purpose of exposure automation. I’ll continue to use it on my Canon EOS M6 because it is much more powerful than the built in flash, and because its size doesn’t overwhelm the camera. I will, however, most likely replace it when I find another of similar specifications.

    Rated 4 out of 5 by from A very nice option Like others, I purchased this flash as a smaller option to my Speedlight 600s and the full frame gear. It works better than anticipated, paired with my Canon T6s, which is often carried in a pack on trails and into outdoor settings when I just can't face the weight and volume of all the full frame gear. Not sure why, but unlike other comments, for me the E-TTL function works as advertised. However, I do have to be aware of distance to subject since it just isn't as powerful as the big stuff. So just be aware that this is a much better option than any pop up flash, but not the same as using large, heavier gear designed for more heavy duty purposes. Pretty much common sense. And of course, much lower cost. Especially with a retailer as good as B & H, I certainly recommend you talk it over with one of the staff or try it, and do a return if it's not appropriate for your needs. A neat little unit, esp. if you are doing some travelling.

    Rated 5 out of 5 by from Excellent compact flash I own the Bolt 710C. Wanted a compact and light weight flash, so last year I purchased the Bolt 260C. What a waste. No features, no control. Just recently, bought the Bolt 310C. What a great flash! Compact, lightweight, plenty of controls and versatility (all for just $30 more than the 260). Love this flash. Perfect for outdoor fill, a light weight indoor flash and as a slave.

    Rated 5 out of 5 by from Great little flash I don't use flash a lot. I originally bought a much larger unit for my Canon camera but returned it because it was just too heavy to carry around. I certainly wouldn't travel with a larger flash unit. But this Bolt flash is nice and light and has a low profile. No, it's not as powerful as the bigger ones but I don't need to light up Times Square. It's far far better than the built-in camera flash. I can use it manually or TTL. I can bounce the light off walls or ceilings and swivel it around. I can even use my softboxes on it. It's perfect for what I wanted. I've only had it a short time so I don't know how long it will last. But the quality seems good and I wouldn't hesitate recommending it to others who don't need the power of the big flashes.

    Rated 5 out of 5 by from Best flash unit ever. Very powerful unit in an exceptionally compact package. Great replacement for bulkier units. Extremely versatile and multi-functional. Works beautifully in iTTL mode and allows flash compensation for creative control. Modeling light is a very useful feature. Best flash unit I have ever had.
    Date published: 2017-03-22
    Rated 5 out of 5 by from Perfect for small DSLR's - always have a camera on hand! It's a powerful (within expectations for its size) flash with full TTL and manual controls, swivel (both directions)/tilt and (some form of) wireless control. Perfect for smaller DSLR's like the Rebel series. It's a lot more powerful and versatile than the pop-up, but a lot smaller than most flashes; Perfect if you have a small camera and smal portable bag that you can always keep with you but want a REAL flash too. Oh, and the included dome-style diffuser and built-in LED is an added bonus!
