Profoto asked me to review the new Profoto B2 off-camera flash system so I put the B2 AirTTL system through its paces shooting some outdoor portraits and photographing kids playing on a trampoline. For this test, I used the Profoto B2 250 AirTTL Location kit, Profoto OCF light shapers, a Nikon D750, the Nikon AF-S 14-24mm f/2.8, the Nikon 24-70mm f/2.8, and the Nikon AF-S 85mm f/1.8.
Here’s a video I put together for the Profoto B2 AirTTL OCF system.
I currently own a set of Profoto D1 Air studio strobes and think that Profoto makes some of the best studio lights on the market today. The B2 flashes take the Profoto technology and shrink it down into a small, battery-powered location kit that you can take just about anywhere. Like everything else in the Profoto lineup, the build quality of the B2 system is top-notch. Also, the quality of light is excellent when used with the OCF (off camera flash) light shapers.
The OCF system uses a battery pack to power the heads. This battery is small in comparison to other location power-pack systems and weighs just a few pounds. It is small enough that you can easily wear the pack with a shoulder strap while shooting events and outdoor action sports.
The heads are 250 watt-seconds each, so they pack about four times more power than a Nikon or Canon speedlight. They also recycle much faster than dedicated flashes, making it easier to photograph action with the B2 system.
The B2 battery pack is designed to hang from a light stand or over your shoulder with a longer strap. Power runs from the battery pack through cables to the B2 heads. These heads are small, lightweight and compact and mount to just about any light stand. The heads work with any of the Profoto OCF light shapers. They also work with the traditional speedrings from other Profoto systems like the D1, D2, etc.
Profoto sells a wide variety of OCF accessories including softboxes, octas, umbrellas, snoots, grids and extension cables so you can move the heads farther distances away from the battery pack. The OCF light shapers are lighter weight than Profoto’s studio light shapers. The OCF material is made out of a reflective silver-coated rip-stop nylon and is constructed very well. It is all designed to go out on the road and perform in any environment.
The AirTTL system allows full remote control of two B2 heads. It mounts on the camera’s hot shoe just like a dedicated flash. The difference is that it communicates with the B2 battery pack while allowing for full TTL control or full manual control of the flash heads. You can control the flash power from the battery pack itself or from the remote control.
The B2 system has built-in modeling lights. These are useful for studio work indoors, but the modeling lights aren’t quite bright enough to use outdoors. The modeling lights could also be used for video lighting in a pinch.
The B2 flashes are powerful enough to use outside on a sunny day. I used them with bright sun in the background and was able to shoot at f/8 and ISO 400 with a rapid recycle rate. Not bad for a small flash system.
Since the B2s are really lightweight, they can be mounted on a flash bracket attached to your camera. You’ll still use the supplied B2 battery with cable, but instead of mounting a typical Nikon dedicated flash like a SB-910, you’ll mount the B2 head to the bracket. Additionally, you can use any of the OCF light shapers while the B2 head is mounted on the flash bracket. The advantage of using the B2 this way is that you can shoot events while getting lots of power, fast recycle rates and lots of shots before the batteries run out.
The entire B2 location kit fits in a small bag about the size of a classic Domke F-2 shoulder camera bag. This means that you can take the B2 OCF system on location just about anywhere in the world and produce high-end results.
My hat is off to Profoto for innovating yet another killer product. The B2 AirTTL Off-camera Flash system definitely gets two thumbs up from me.

This week I’m shooting about 250 portraits for Harbor Covenant Church. I’ll share more of the results of the photo shoot in a future blog post, but in the meantime, I wanted to show how I set up the studio with this time-lapse video. My goal for the photo shoot is to produce a bright white background for each of the portraits. To do this, I used a white muslin backdrop and lit it with four slave flashes in umbrellas. These background flashes are set to produce about 1.0 to 1.5 stops more light than the Profoto D1 monolights I’m using for the people in the foreground.
I’m triggering everything optically, which is another way to say that all the flashes are set to fire when they see a flash pulse from the main camera. For the Profoto D1 monolights, I’ve set them to trigger using the IR mode. For the Nikon flashes, they are all set to trigger in SU-4 mode. On my Nikon D800 camera, I’m triggering everything with a Nikon SB-700 flash set to manual output so that when it fires, everything else fires. All slave flashes are set for manual output and I metered everything using my trusty old Sekonic L-358 (no longer sold).
Here’s all the gear I used to create the location studio.
Just wrote a review for a great new product called Capture Pilot from the good people at Phase One. The product allows anyone with an iPad, iPhone or iPod Touch to view photos from a tethered photo shoot in real time. The product is truly awesome. Check out the article and see how I used it to photograph a bunch of young kids in an impromptu hotel studio.
