Camera Compatibility. As of November 2019, the Profoto Air Remote TTL-O Transmitter for Olympus/Panasonic is only compatible with the Olympus E-M1 Mark II, E-M5 Mark II, and PEN-F, and the Panasonic DC-S1R, DC-S1, GH5, Panasonic GH5 w/V-Log, GH5S, and G9.
Profoto Air System. The Air Remote uses this radio-frequency system, which is built into lights like the Profoto B1 500 AirTTL Battery-Powered Monolight, the B2 250 Air TTL To-Go Kit / Location Kit, and the D2 500Ws AirTTL Monolight / 2-Light Kit.
Full TTL Control. This remote gives you fully automated control of compatible Profoto strobes with compatible Olympus and Panasonic cameras.
Radio Triggering. You get eight frequency channels to choose from, with three groups per channel. It offers a range of up to 330 feet when triggering via TTL, but normal manual triggering extends that range to 1,000 feet. Each channel has a power ratio adjustment of +/- 2 stops; however, if you’re manually adjusting output, you get a full +/- 9 stops of power variation.
High-Speed Sync Mode. This remote’s High-Speed Sync (HSS) Mode lets you shoot at shutter speeds as fast as 1/8,000 of a second, and helps you to control ambient light and freeze action. You can enable HSS Mode with the press of a button.
Build. The Air Remote slides into and is triggered by your Olympus camera’s hot shoe. There’s a digital readout of your light setup, and a variety of physical buttons for making adjustments. It’s powered by two AAA batteries, which aren’t included with this rental.
