A1 for Canon UK The world's smallest studio light

Product number: 901201-UK

The Profoto A1 is designed with light shaping capabilities; it has a unique round head with a soft, smooth fall-off that makes it easy to create a natural and beautiful light. It also includes a smart magnetic mount and three dedicated A1 Light Shaping Tools that click on and off quickly and easily – a Dome Diffuser, Wide Lens and Bounce Card. They can be stacked for more creative options. The A1 also offers a built-in LED modeling light that makes it easy to set the light and understand how light and shadows work together.

And it’s extremely easy to use. The user interface is large, clean and clear. Like all Profoto products, it’s intuitive to use and you don’t need to read a long instruction manual to understand how it works. AirTTL remote is also built in to the A1. With AirTTL and HSS you create professional results fast and easy and with the remote you can seamless connect to other Profoto flashes and control them easily from the A1.

Profoto A1 is not only an on-camera flash, it’s also very effective off-camera as a standalone unit. The A1 has its own Li-Ion high capacity battery built-in that lasts up to four times longer than AA batteries with no performance fade, and a facility to recharge quickly. So you can shoot for longer with confidence. A1 can keep up with you because it recycles four times faster than other on-camera solutions – that’s 1.2s at full power. Put simply, you’ll never miss a shot.

Can I control lights individually from the A1 and how do I do it?

Yes, set the off-camera lights in different groups. By selecting a specific group on the remote or A1 on-camera you can easily control most settings on the lights. Note that group A, B and C can be TTL or manual and group D, E, F are always manual.

Can I travel by air with A1 and its batteries?

Yes. Our Li-ion batteries are UN-certified so you can take them on a plane, no matter what your destination. All the documentation you need can be found under the download tab.

The Soft Bounce disconnects too easy when used in combination with other modifiers?

Make sure the Soft Bounce is mounted directly on the A1 head. If you use any modifier in between this will weaken the connection.

How do I optimize to get maximum frame rates, FPS?

Some cameras restrict maximum speed when using flash on camera. By using ‘X-SYNC’ you can shoot up to 20 frames per second. The X-sync mode only works in manual mode and without High Speed Sync.

Can I use the A1 in wet conditions, as rain or snow?

The A1 is designed to be used in dry conditions and should not be used in rain or snow.

I get over exposed images when shooting in bright conditions even if TTL is enabled?

For Canon users, make sure ‘Hi-S’ is activated. If not, the camera will sync at maximum sync speed which is normally 1/200s or 1/250s. That will normally result in an over exposed image in bright condition. For Nikon users, make sure ‘Auto FP’ is activated in the camera so that a fast shutter speed can be used.

Can I use the A1 to control my other Profoto lights?

Yes, the A1 has a built-in Air Remote that can control Profoto Air lights up to 300 m (1000 ft.).

How do I best create large, soft lighting with A1?

The easiest way is to use umbrellas to create soft lighting. Use a stand adapter with hot shoe connection and umbrella mount. You can also use Profoto RFi Speedlight Speedring together with the full range of RFi Softboxes.

I get black horizontal lines across the image when shooting with LED modeling light?

At some settings the LED will flicker which can result in lines across the image. Follow the instruction ‘Can I use the modeling light on the A1 for video and still images?’ in this FAQ how to set the model light for best result.

TTL/HSS randomly works when the A1 is mounted on camera?

Make sure the contacts are clean and have contact. Also make sure the locking ring is tightened.
