The Profoto D1 1000 is a solid all-rounder that delivers best-in-class performance time after time, a great step-in monolight. With a 7 f-stop power range and short flash duration, its performance stacks up well against many of the high-end studio packs. It can also be wirelessly controlled from up to a 300 m range with any optional Air Remote. Unlike the Profoto D2, it does not offer TTL or HSS.
