Minimum flash duration of 1/63,000sec makes the Profoto D2 the fastest TTL monolight in the world

17 Sep

Flash manufacturer Profoto has launched what it is describing as the fastest TTL monolight heads in the world. The Profoto D2 studio flash heads have a shortest output duration of 1/63,000sec, can run at a rate of 20 bursts per second and can sync with camera shutter speeds as short as 1/8000sec. The heads come in two output varieties, 500Ws and 1000Ws, with both featuring full TTL control for Nikon and Canon users via the company’s AirTTL 2.4GHz radio system. The heads can also be controlled in manual mode with 10 stops of output in 1/10th stop increments.

The heads are available to order now, retailing for $ 2000/£1554 for the Profoto D2 1000Ws AirTTL Monolight and $ 1500/£1194 for the Profoto D2 500Ws AirTTL Monolight.

Press release

Profoto releases the D2, the world’s fastest monolight with TTL

With the ability to freeze action at up to 1/63,000 of a second, to shoot bursts of 20 images per second and sync with camera shutter speeds as fast as 1/8,000 of a second the D2 is redefining the definition of speed in monolights.

“For a photographer, every new day is a new challenge. So for them, speed isn’t one thing – it’s many. That’s why we created the D2 to be remarkably fast in every way” says Johan Wiberg, Product Manager at Profoto.

A photographer might need to freeze action with absolute sharpness. The D2 brings pin sharp clarity with a flash duration of up to 1/63.000 of a second, which makes it faster than most high end studio packs on the market. Better still, it offers supershort flash duration across the full energy range.

If flash duration is exceptionally fast, recycling time is equal to it. With the D2 you can shoot up to 20 flashes per second . That allows you to catch 20 versions of the same moment, and quite often that’s the difference between capturing a good image and a great image.

Bringing yet another dimension to speed is Profoto’s High-Speed Sync technology (HSS). This allows the D2 to sync with the fastest shutter speeds available. An advantage when you need to catch a deep blue sky or take full control of ambient light.

The D2 can also help to speed up workflow because it’s equipped with patented TTL technology. You can point-andshoot and the D2 will automatically adjust its output for perfect exposure. But manual mode is available at click of a button, so switching between both modes with settings intact just makes everything move faster.

In terms of output, the D2 is available in 500Ws and 1000Ws versions. At full power you’ll easily overpower the sun, or fully illuminate a larger Light Shaping Tool. Both versions come with a super wide 10 f-stop energy range and superior color consistency over the entire range. So leave the ND filters at home and add just a hint of light if needed.

Above all, this is Profoto Light Shaping equipment. So the design is smooth and minimal, it’s intuitive to use, the build quality as you’d expect, is rugged and sturdy, and it can be used with more than 120 different Light Shaping Tools.

“We designed the Profoto D2 to be the world’s fastest monolight,” says Johan Wiberg, Product Manager at Profoto. “But the speed is not a gimmick. We truly believe that more speed allows you to be more creative and consistently take better images regardless of what challenge you face – with the D2, you’re always up to speed.”

For high volume production when you shoot thousands of images per day, like packshot photography, there is an optional Quartz flashtube available.

The D2 is released Sept 15, 2016. Both the 500Ws and 1000Ws versions are available in different kits configurations.

Vela One LED promises 1/2,000,000 flash duration for the price of a normal hotshoe gun

02 Dec

An inventor from Bristol in the UK is developing an LED-based light source for high speed photography, promising to produce a burst of flash with a duration short enough to freeze a bullet. The Vela One, which will be priced at a similar level to standard hotshoe flashguns, uses nine LEDs arranged in a bank that generates a million lumens and is powered by just four AA cells that the inventor claims will last a full day’s shooting. Learn more
