A1 for Canon The world’s smallest studio light
Product number: 901201-INT
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. 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 exchangeable battery 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.

Yes, since they are magnetic, you can stack different A1 modifiers together. When using Soft Bounce, please make sure to fit additional modifiers on top on Soft Bounce and not under it. This will make sure best fitting of the Soft Bounce.
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.
Yes, A1 can be used with full functionality with any Profoto Air Remote TTL on camera. It doesn’t matter which brand A1 is made for when it is used off-camera.
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.
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.
Make sure the Soft Bounce is mounted directly on the A1 head. If you use any modifier in between this will weaken the connection.
Make sure the contacts are clean and have contact. Also make sure the locking ring is tightened.
Enable ‘Air’ in the menu and select same channel on both transmitting and receiving unit and you are ready to shoot off-camera.
In the camera, select ‘Auto FP’ and you are ready to use any shutter speed on the camera.
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.
