About Quantum

Diffusing UV filter kit. 1 diffuser reduces light output by 2/3 stop. 2 diffusers will reduce light output by 1 1/3 stop.The more diffusion, the softer the light and softer shadows.

The Qflash compensates for this in both automatic and TTL modes.

Great Product!!

A q flash plus.


Does exactly what it is supposed to do

I had lost the retaining ring for my Q-flash and needed to replace it. That along with the UV diffusing filter, which is great for using with gels, made this purchase an easy call.

Questions about this item:

gwendolyn j  Can I use the Quantum Q Flash X2 with my Nikon D300?
JOHN I  Not in TTL mode. The D300 has a PC sync outlet which you can use to fire the quantum flash in manual mode. The quantum has an automatic mode, but you have to set the flash and camera together. Since you are asking, I assume that you are not familiar with the Quantum flash series. You need a battery pack or AC adapter to use Quantum Qflash; they do not take internal batteries. For the Quantum X series, you need a Qpac-x battery pack (not common these days) or a compatible Norman or Lumedyne battery pack and adapter cable (not easy to find either).
