    A new option for flashers

    I stumbled across these on an Australia camera shop site today. I suspect that they may be a good option for some people interested in bug or product photography.



    Ray Flash web site here.

    BTW they wanted Aus$300.00 for one here I'm sure they will be way cheaper on some auction sites.

    Those have been out for quite some time :P

    From all I've read about them and videos/samples I've seen they are ok for indoor use. They don't give as good of an effect as a real ring flash does and are usless outdoors in sunlight because of the massive power loss due to the design.

    You can get them (different branding) for $50 US on Amazon and the same brand for $199. I thought these had their own power source - didn't realize they used your onboard flash.

    They don't use on board flash, they use a shoe mounted flashgun. I jury rigged something like this out of an old frisbee and a pringles tube, which is a cheaper but bulkier solution. I might have another go with lighter materials sometime.

    Ya, they attach to hot shoe flashes but because the light has to travel down the tube the spread across the ring there is a massive power loss. Real ring flashes have there own bulb and require battery packs to operate but they also cost hundreds of dollars.

    Surely the insides of the tubes would be silvered so not much light is lost?

    Dunno what its coated with but there for sure is a loss in power. Real ring flashes have a bulb in the ring itself so the light doesnt have to travel very far before being projected. The Ray Flash has to go through the tube then across the surface of the ring THEN project. Most reviews say it loses at least 1 stop of power. May not sound like much but in sunlight flashes are already on the weak side power wise so every bit is important.

    Seems odd, if they're well designed they shouldn't lose that much light. It could jsut be that the light is spread out more as they have a much larger diffuser than normal ringflashes, which are pretty compact by comparison. So it's not that the light is lost inside, just scattered off worthlessly outside.

    When you are diffusing light, you will lose some. Even efficient soft boxes lose light.

    Yup. And when your light source is already putting out less power than the competition one may not want to then lose another stop worth of power.
