Why is the D2 the world's fastest monolight with TTL?

We created the D2 to be remarkably fast in every sense. Freeze the moment The D2 can provide super quick flash durations up to 1/63,000 of a second. Shoot a splash of water and it will be frozen in mid-air – a photographic work of art. Catch the moment The D2 can shoot up to 20 flashes per second. That’s fast enough to catch the best of any moment. Ask your subject to jump and you’ll have 20 mid-air exposures to choose from. Control your surroundings Profoto High-Speed Sync (HSS) enables you to shoot with shutter speeds up to 1/8,000 of a second. Use HSS to shoot with large aperture in bright conditions or to freeze action with absolute sharpness. Shoot with ease using TTL Point-and-shoot in TTL Mode. Switch to Manual Mode and control the light with intuitive buttons and menus. Forget about the flash and focus on the light. Overpower any light The D2 packs enough of punch to overpower the available light in almost any situation. Its power is also a blessing when shooting at larger distances or when using larger Light Shaping Tools. Grow with speed It has the speed to set you free, and the power for you to be at your best. It’s an integrated part of the extensive Profoto system. Go full speed ahead with the D2.
