Profoto B1 500 Air Battery-Powered 2 Light Location Kit
Items included in this Kit:
- two B1 500 off-camera, battery-powered AirTTL flash heads
- 4.5A Fast Battery Charger
- custom location backpack
- Optional Air Remote TTL-C, TTL-N, Air Remote or Air Sync for wireless triggering from distances up to 1,000
Advantages to using the B1
- The B1 is as easy to use as your TTL flash.
- The B1 offers double wireless freedom - a built in AirTTL receiver for remote triggering as well as a powerful on-board Lithium-ion battery that untethers you from the wall outlet.
- The “Fast Battery Charger” provides up to 220 500W/s flashes on a 60 minute charge.
- The car charger allows you to refresh the battery while you drive to your next shoot.
- The kit fits in an included ballistic nylon backpack which was tailored for it. Its interior features padded compartments and room for expendables and optional Profoto transmitters.
The B1 offers full TTL exposure plus remote triggering for Canon cameras via the optional Air Remote TTL-C and for Nikon cameras via the TTL-N. The B1 can also be triggered remotely with the Air Remote or Air Sync without TTL functionality.
High speed sync
With the release of Profoto HSS, the possibilities grow even greater. Download the free HSS firmware upgrade today and start shooting with superfast shutter speeds. Get that perfect deep blue sky even when shooting with large apertures. Capture super crisp action shots without motion blur caused by the ambient light.
Recycle time and flashes per second.
The B1 recycles in 0.1 to 1.9 seconds but can deliver up to 20 flashes per second in Quick Burst Mode which engages at lower power settings. Flash duration in Normal Mode is a very fast 1/1,000 sec. but there's also a Freeze Mode that delivers flash durations as short as 1/19,000 sec. for capturing liquid sprays or splashes and other creative effects.
The modeling light has been upgraded to LED to put less strain on the battery and provide the equivalent output of a 70W tungsten-halogen bulb.
The B1's exchangeable Lithium-ion battery gets up to 220 flashes on a 2-hour charge with the standard 2.8A charger or a 1-hour charge with the 4.5A Fast Charger. The battery has fuel gauge-type LEDs that make monitoring remaining power easy.
Full E-TTL II with Canon Cameras or i-TTL with Nikon Cameras
The B1's patent-pending technology fully integrates the flash head with your Nikon or Canon camera. The integration is so complete that Profoto sometimes refers to the B1 as an "off-camera flash." The key to this control is the Air Remote TTL-C or TTL-N.
Optional Air Remote TTL-C / TTL-N
The Air Remote TTL-C and TTL-N transmitters have 8 frequency channels with 3 groups per channel and a range of up to 330' for 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.
Lithium-ion Battery Powered
The B1's Lithium-ion battery gives you up to 220 full power flashes and thousands of minimum power flashes on a 2-hour charge from the provided 2.8A multi-voltage charger. An optional 4.5A quick charger shortens that time to 1 hour. Fuel gauge type LEDs on both the battery and charger allow you to monitor remaining power.
Exceptionally Short Flash Duration
In Normal Mode, which prioritizes color fidelity, the B1 500 AirTTL is capable of t0.5 flash durations of 1/11,000 sec. at minimum power, and 1/1,000 sec. at full power.
Freeze Mode automatically selects the shortest flash duration possible at the user-selected power level. Motion-stopping flash durations of 1/19,000 at minimum power make the B1 500 AirTTL ideal for high speed shooting.
Quick Burst Mode
At lower power settings Quick Burst Mode allows a series of flashes to be fired at a faster pace than the B1 can recharge, allowing triggering of up to 20 frames per second.
LED Modeling Lamp
A 20W LED modeling light with a 70W tungsten-equivalent output draws very little power from the battery and generates minimal heat. The light can be set to proportional or full power and will dim during recycling if that option is selected.
Redesigned Control Panel
The B1's control panel has been upgraded with a 1.4 x 2.5" bright LCD screen that informs the user of the flash's Power level, sync choice, modeling light mode and recycle alert. There's also a large battery gauge that literally can be read from 20' away
Both the flash head and the Air Remote TTL-C have mini-USB connections for firmware updates directly from Profoto's website.
Power Variable over 9 Stops
Power can be regulated over a 9-stop range (2.0 - 500W/s / 1/256 - 1/1) in 1/10 or 1-stop increments.
Full Light Shaper System Compatibility
With its zoom scale and integrated umbrella sleeve, the B1 500 AirTTL is compatible with Profoto's extensive line of umbrellas, reflectors and softboxes.
