About the Profoto B1 500 Air TTL Monolight

The Profoto B1 500 AirTTL Battery Powered Monolight Flash makes it easier than ever to take the flash off your camera. With AirTTL you set the light in a flash. With battery power and a clever design with no cables or cords, you can take the B1 with you wherever you go and put it wherever you want. Add to that the power, speed and light shaping possibilities that Profoto lights are known for, and you have an off-camera flash that makes great light easy.

The B1 has the same dense, durable polymer housing, integrated 77-degree reflector, built-in receiver compatible with Air transmitters and intuitive highly visible controls and display as the D1 but with two striking differences - battery power and TTL camera/flash integration. Photographers can set up their lights, slip the optional Air Remote TTL-C transmitter onto their camera's hot shoe without taking a reading and testing. Traditionally point-and-shoot would be a suspect term for a pro, but not if you're shooting back to back jobs.

The key to this control is the Air Remote TTL-C transmitter for Canon DSLRS operating on 2.4GHz band width, the transmitter, really a controller, has 8 frequency channels and with 3 groups per channel and a range of up to 330ft. for TTL triggering and 1,000ft. for normal triggering. Each channel has power ratio capability of +/- 2 stops. The TTL-C and the B1 500 Air TTL have mini-USB connectors for firmware updates directly from Profoto's website. The head can be triggered by any Air Remote but requires the TTL-C for full functionality.

The B1 recycles in 0.1 to 1.9 seconds but can deliver up to 20 flashes per second in Quick Burst Mode, flash duration in Normal Mode is a very fast 1/1000 sec but there's also a Freeze Mode that delivers flash durations a short as 1/19,000 sec. The modeling light has also been upgraded to LED to put less strain on the battery and provide the equivalent output of a 70W halogen bulb. The B1 500 AirTTL employs a exchangeable Lithium-ion battery that gets up to 220 flashes on a 2-hour charge with the included 2.8A charger or a 1-hour charge with an optional 4.5A quick charger. The Battery has fuel gauge-type LEDs that make monitoring remaining power easy. B1's the back panel has been upgraded with a large, bright LCD screen that informs the user of the flash's power level, radio channel and group, sync choice, modeling light mode and recycle alert. There's also a large battery gauge that literally can be read from 20' away. The B1 500 TTL comes with protective cap, 2.8A charger and a soft case.

Profoto B1 500 Air TTL Monolight Features

  • The B1's patent-pending technology fully integrates the flash head with your 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
  • It has 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
  • 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
  • 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
  • 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
  • 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
  • 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 can be regulated over a 9-stop range (2.0 - 500W/s / 1/256 - 1/1) in 1/10 or 1-stop increments
  • With its zoom scale and integrated umbrella sleeve, the B1 500 AirTTL is compatible with Profoto's extensive line of umbrellas, reflectors and softboxes
