Welcome Very Happy

High speed flash is what I use. Generally a Sunpak 555 or 552 set for 1/64,000th of a second. that particular setup, stops most things in their tracks Very Happy

All the best in Norway Very Happy

Yes, they are flashes. Google on "Sunpak", you'll find them quickly.

With most flashes, the light pulse gets shorter when you turn the power down. At full power, it's usually around 1/1000th second. 6 stops down, it's at 1/64,000th.

1/200 second is a typical minimum speed for a mechanical shutter, regardless of how short the flash is. The shutter has to come completely open before the flash fires. The trick is to work in light that's dim enough to record no image during the 1/200 second, except for that very brief instant when the flash fires.

Yes quite right Rik. Turning the power down on the Sunpak's to a quater power sets them at 1/64,000th sec. So its less light output but faster flash duration.

I need some enlightenment as well folks.

Is anyone familiar with Sunpak's ringlight DX-12R or various dedicated fixed mount flashes? What are their flash speeds and which would be best for high magnification macro? What accessories would be needed to use them with Canon EOS cameras?

Thanks.
