The Profoto A1 AirTTL Studio Speedlight for Nikon is a super portable on-and off-camera flash designed for creating natural and beautiful light. It features a rounded head with a focusable Fresnel lens for a softer effect than the typical speedlight. It boasts 76W of power and thanks to TTL capability, the Profoto A1 supports High-Speed Sync at up to 1/2000 sec. Inside you'll find a lithium ion battery that's good for 360 full power flashes on a charge, and your recycle time is just 1.2 seconds. It comes with three magnetic modifiers, including a dome diffuser, bounce card and wide lens and optional (sold separately) colour-correction filters and a gel kit.
