We keep receiving questions about the new B1 off-camera flash, and we keep doing our best to answer them!
You’ll find the answers to the most common questions in the FAQ below. In addition, there’s a bunch of more specific questions in the ever growing comment section.
For your information, this page will continuously be updated. So if you have a question that isn’t answered here, leave a comment or tweet us, and we’ll insert it into the FAQ as soon as we can.
1) Which Canon cameras allows me to use the TTL function?
The Air Remote TTL-C supports TTL flash metering with most Canon EOS cameras with the ETTL-II metering system. A complete list of all Canon cameras and Profoto flashes compatible with the Air Remote TT-C is available here. The Air Remote TTL-C does currently not support TTL with Canon Powershot cameras. But know that the Air Remote TTL-C’s firmware is user upgradable. Needless to say, we’re working on including more compatible camera models and new features in future upgrades. Next upgrade is planned during Q1 2014.
2) Can I use the Air Remote TTL-C with cameras that are not listed above to sync and control the B1 off-camera flash?
No. If you have a Canon EOS camera with ETTL-II metering, choose the Air Remote TTL-C and get full TTL functionality. If you have any other camera (Canon, Nikon, Sony, Phase One, Hasselblad or whatever it may be) choose the standard Air Remote to sync and control the B1 off-camera flash.
3) Can I use the Air Remote TTL-C with older Profoto flashes and thereby access the TTL functionality?
4) Can I use the standard Air Remote to sync and control the B1 off-camera flash?
Yes, you can use the standard Air Remote to sync and control the B1. No TTL functionality of course. But sync and control, yes.
5) Can I use the Air Remote TTL-C to sync and control other Profoto flashes?
Yes, you can use the Air Remote TTL-C for syncing any Profoto AirS flash, such as AcuteB2 AirS and Pro-B3 AirS, and for syncing and controlling any Profoto Air flash, such as D1 Air and Pro-B4 Air. Just remember that the Air Remote TTL-C only works with the Canon EOS cameras with the ETTL-II metering system – even in manual mode. A complete list of all Profoto flashes and Canon cameras compatible with the Air Remote TT-C is available here.
6) Will there be an Air Remote TTL-N for Nikon cameras?
Yes, there will! Next year. Sign up for our newsletter and you will be the first to know when it’s released. Notice that it’s only the Air Remote TTL-N that is unique for Nikon users. The B1 off-camera flash stays the same..
7) Why did Profoto choose to release the Air Remote TTL-C for Canon cameras before the Air Remote TTL-N for Nikon cameras?
The short answer is: backwards engineering is a tricky business. In other words, it’s not because we like one better than the other. We love Nikon cameras and would’ve preferred to release both at once. But as it turned out, one was finished before the other, and rather than waiting several months before releasing the B1 off-camera flash, we did it this way.
8) Will there be any additional Air Remotes for other camera brands?
We’re currently devoting our full attention to making the compatibility with Canon and Nikon as good as it can possibly get. That being said, we’re not closing any doors. Ideally, we’ll have Air Remotes for all camera brands in the future.
9) Can I use the B1 with PocketWizard® units or other radio triggers?
Yes. If you use the Air Remote TTL-C you can slave sync your speedlights either by activating the optical slave on your speedlight or by connecting an Air Sync or an Air Remote unit to the sync jack of your speedlight. The B1 also has an optical slave and a sync jack, so if you are already using speedlights off-camera with PocketWizard® or other radio triggers, you can slave sync B1 as well!
10) What is Quick Burst Mode and how does it work?
Quick Burst Mode is activated as soon as the B1 off-camera flash’s output is set below full power. You can think of the Quick Burst Mode like a tank of energy with an adjustable tap in one end (the output control) and an automatic fill-up in the other (the charger). The charger continuously strives to keep the tank full, while the output control allows to tap as little or as much as you’d like from the tank. As long as there is energy left in the tank, it can be tapped. But if you tap faster that the charger can fill it up, you will eventually empty the tank.
A couple of examples:
- When the B1 is set to full power, the tank will be completely emptied in a single flash. In other words, Quick Burst Mode is not activated.
- When the output is set to three stops below full power, you will empty 1/8 of the tank with every flash, which means that you can flash eight consecutive times with almost no delay in between. On the other hand, if there is a short delay in between the flashes, the charger will use this time to once again fill up the tank, adding even more flashes to the burst sequence.
11) Does the B1 Off-Camera Flash support High Speed Sync (HSS)?
Yes it does! 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. Download it here:
You will also find our most frequently asked questions regarding HSS here:
Yes, you can! At full power, the B1 has a longer flash duration than the D1 500. But contrary to the D1, the B1’s flash duration shortens when you dial down the power. At one f-stop below full power, the B1’s flash duration is equal to D1’s. Turn it further down and the B1 will have a significantly shorter flash duration. At the lowest power setting, you’ll have a flash duration of 1/19,000 of a second! So yes, you can easily freeze water with the B1! If you want to take a closer look at how the flash duration changes depending on the power setting and the Freeze Mode setting, there’s a chart available in the B1 user guide.

13) Can you connect the B1 off-camera flash to the wall outlet?
No. Including that function would’ve resulted in a much larger unit, and in this case we valued portability and ease-of-use higher than anything. What you can do is to get yourself one or two Spare Batteries and recharge while shooting. The battery recharges in only one hour with the Fast Charger. There is also a Car Charger available, allowing you to recharge the battery in your car cigarette connector.
14) Can I use my D1 accessories, such as grids and glass domes, with the B1?
Yes, you can. That’s partly why we made the B1 so similar in design to the D1, even though they’re quite different on the inside. The B1 can, of course, also be used with the same Light Shaping Tools as all the other Profoto monolights and flash packs.
15) Can I replace the B1’s flash tube myself?
Yes, you can. You just remove the glass plate, remove the metal pin holding the flash tube and pull it out. It’s very easy, but if you feel nervous about it, take it to an authorized service station and see how they do it.
16) How many full power flashes can I get out of a single battery?
220 full power flashes. Up to 50,000 flashes at lowest power!
17) I’m thinking of using the LED modeling light for video. What is the color temperature?
The battery provides 90 minutes of full power modeling light, so that’s totally possible. The LED modeling light has the same color temperature as a tungsten lamp: 3.000K.
Please note that the LED light from the B1 is a modulated square pulse. The LED needs fixed voltage, and therefore the variation on modeling light is controlled by a pulls length modulator. The pulses can be measured as a flash pulls from the light meter, so recommendation is to switch of the modelling light when using the flash meter.
18) Will there be any other versions of the B1 released, such as a 250Ws or 1.000Ws version?
Maybe. It’s too early to say at this point. We’re now focusing on the 500Ws version and are curious to see how it’s received by photographers worldwide.
Hope that helps! If not, leave a comment or tweet us and we’ll get include your question in this FAQ asap!
