Product description In what is starting to seem like an annual event, Profoto has once again introduced a breakthrough product. This time it is the B2 250 AirTTL Power Pack, a part of the expanding OCF (Off-Camera Flash) system that includes the optional B2 flash head. Like another family member, the B1 battery-powered monolight, it boasts full TTL operation with Canon and Nikon cameras with the purchase of an optional Air Remote TTL-C or TTL-N. Just set up your lights, point, and shoot - you're first shot is usually a keeper. It's actually that easy.Really a controller, the optional Air Remote TTL-C or N has 8 frequency channels with 3 groups per channel and a range of up to 330' for TTL triggering and 1,000' for normal triggering. Each channel has TTL power ratio capability of +/- 2 stops. If you prefer to use manual, you have +/- 9 stops power variation. You've also got modeling light, unit shut-down, and first- or rear-curtain sync control. The remote also has a mini-USB connector for free firmware updates directly from Profoto's website. Intended for the road, the pack measures 6.3 x 3.1 x 6.7" and weighs in at just 2.2 lb with its optional Li-Ion battery. Sheathed in rugged polymer and rubberized at the top and bottom against impact, the B2's twin outlets each have a dedicated thumbwheel that allows the pack's 250Ws of power to be distributed asymmetrically over a 9-stop range in full or 1/10 steps.The 1.75 x 2.25" digital LED screen that displays the power settings is also the key to the pack's many capabilities. Like the B1 before it, the B2 is a real performer, with recycling times from 0.03 - 1.35 sec. and an action-stopping flash duration of 1/1,000 sec. There's also a Freeze Mode that selects a flash duration of 1/15,000 sec. at lower power settings - fast enough to "freeze" water droplets, spray and splashes. The pack and optional head also fire bursts of up to 20 frames per second. High Speed Sync allows shutter sync speeds from 1/4,000 - 1/8,000 sec., giving you extremely wide ambient light options. If you're starting to see a resemblance to the B1, it is completely intentional.The B2's Li-Ion battery can be charged in or out of the pack and will give you up to 215 full-power flashes on a 45-60 minute charge from its optional multi-voltage 2.8A battery charger or a trickle charge from an optional car charger. Both can also be used with the B1 Off-Camera monolight. The battery has a built-in gas gauge type LED power level indicator, but you can also check battery status on the top panel LED display.The B2 250 AirTTL Power Pack is also available in kits with 1 or 2 B2 Off-Camera Flash heads, a charger, and a battery or batteries depending on the kit. It all fits in the kit's Location and Carry Bags that measure only 16 x 9 x 9". - Full TTL with Optional Air Remote TTL-C / TTL-N
- The optional Air Remote TTL-C and TTL-N transceivers for Canon and Nikon Cameras have 8 frequency channels with 3 groups per channel and a range of up to 330' for full TTL triggering. Each channel has power ratio capability of +/- 2 stops in TTL or +/- 9 stops in manual. Modeling light, shut-down of the unit and first or rear curtain exposure can also be selected
- On or Off-Camera Flash
- The separately-purchased B2 head is small and light enough to be put on a bracket on your camera as well as a monopod or stand. Intended for the road, the pack measures 6.3 x 3.1 x 6.7" and weighs in at just 2.2 lb with its optional Li-Ion battery. An entire B2 kit fits in a bag no larger than your average shoulder bag
- Speed, Short Flash Duration and Freeze Mode
- At full power, the B2 250 AirTTL power pack with its separately-purchased flash head recycles in 1.35 seconds. In Normal Mode, which prioritizes color fidelity, the B2 offers flash durations of 1/1,000 sec. while Freeze Mode gives you flash durations as short as 1/15,000 sec. at lower power settings for dramatic action-stopping shots. At lower power settings there's also a burst mode that allows triggering of up to 20 frames per second
