SF300 High Speed Studio Flash Head FLA013
6 stops of power adjustment. A full 6.6 stops of adjustment opens the creative possibilities and allows larger apertures to be used when needed
S1/S2 slave options, the slave cell can be set to either respond to or to ignore the first flash, allowing it to be used with hotshoe flashguns that fire a pre-flash
Full remote control via USB port. This allows you to set the controls on the SuperFast using our Wavesync Commander. as well as on the flash head
Uses the same remote control as our other new technology flashes. This means that you can use the SuperFast in conjunction with our other new technology flashes (ElitePro 2, Atom, SmartFlash 2 and future models) and control all of them individually from the transmitter fitted to your camera hotshoe.
S1/S2 slave options, the slave cell can be set to either respond to or to ignore the first flash, allowing it to be used with hotshoe flashguns that fire a pre-flash. The slave cell can also be switched off so that it doesn't flash in response to other people's flashes.
Fan cooled, to avoid the risk of overheating. It also has overheat protection, for extra safety.
Precise digital control of power displayed on the display panel. The digital control knob adjusts the power setting and displays it on the control panel.
250W Halostar lamp, fully adjustable by separate control, and fitted with a safety dome.
This revolutionary new flash head uses IGBT technology to produce incredibly short flash durations that can freeze even really fast action such as jumping, dancing, hair, martial arts and even bursting balloons, as well as all the other jobs that a high-quality studio flash head can do!
Insulated-Gate Bipolar Transistor technology works in the same way with this new flash head as with hotshoe flashes, which means that the flash duration becomes progressively shorter when the power is reduced, this is the opposite of what happens with conventional flash heads. At full power, the SF300 produces 300Ws of flash power and behaves exactly like a conventional flash head, with a respectable t.1 flash duration of just 1/1600th second, this reduces to an incredible 1/20,000th second at minimum power, again this is at t.1. As you can see from the photos, you will even be able to freeze the incredibly fast movement of clothing being hurled through the air, or a jugful of milk hitting the poor model!
And you can easily shoot a sequence of shots in 'machine gun mode' or even make multiple shots on the same frame.
And, as the power is reduced, the recycling times become progressively shorter, and even the fastest cameras can't keep up with it at low power settings!
This is the perfect solution for all studio photographers who, up until now, have been forced to use hotshoe flashguns, with their power and accessory limitations, and the lack of a modelling lamp, whenever they have needed to freeze subject movement.
And our optional Wavesync Commander System allows full remote control of all functions, in addition to triggering the flash head. To get the maximum benefits from the set, it is advisable to have a separate receiver for each additional flash head.
Here are the flash duration test results, published in Advanced Photographer. They (and many other testers) use a spinning disk as the test method, and simply takes a series of photographs using a high-performance camera without flash, these shots are taken at various shutter speeds and provide a benchmark, showing the action freezing potential at any tested shutter speed. The shots are then re-taken, this time using the flash unit under test, and the results can then be compared.
It's a pretty good testing method because shots taken at, say, a shutter speed of 1/10.000th second produce a very similar result as a flash with a t.1 time of 1/10,000th second.
The problem though, is that although this is a very useful and meaningful test, it isn't scientific - a visual comparison needs to be made, and an estimate arrived at.
The first 4 photos (above) show the action being frozen (or not) by using various shutter speeds on a camera, using ambient light. The other photos shows the same subject, with the SuperFast flash head being used at normal shutter speeds. Professional DSLR cameras tend to have a maximum shutter speed of 1/8000th second, which is nowhere near fast enough for comparing their action freezing potential to the SuperFast.
The focal plane shutters fitted to DSLR cameras inevitably create a distorted image of a spinning disk, due to the movement of the disk as the camera shutter moves across the sensor, and this makes estimation difficult.
The camera used in these tests was a Nikon V1, which has a very fast electronic shutter, producing a shutter speed of 1/16,000th second.
You will see that the distortion here is even worse, making an accurate comparison between the freezing effect of a camera shutter and the freezing
effect of a flash even more difficult to compare, but it's the best method available.
This distortion does not occur when taking photos using the SuperFast.

|Flash duration at maximum power, t.1||1/1600th second. This approximates to the action stopping potential of using a shutter speed outdoors of 1/1600th second. The figure used by most sellers is based on a t.5 time, which produces a much higher figure but which is far less meaningful.|
|Colour temperature consistency||Variation between flashes is too small to measure except at minimum power. At minimum power, the variation is less than 100K|
|Flash duration at minimum power, t.1||1/20000th second. This approximates to the action stopping potential of using a shutter speed outdoors of 1/20000th second. The figure used by most sellers is based on a t.5 time, which produces a much higher figure but which is far less meaningful.|
