Rogue has announced a nifty, battery-free attachment that should enable anyone using the pop-up flash on a Canon or Nikon dSLR to send its light further than it could otherwise reach. The Safari Flash Booster has been optically engineered to focus up to eight times more light from a pop-up flash and optimized for lens focal lengths over 100mm. With luck, it should enable you to use faster shutter speeds and achieve sharper photos.
The Rogue Safari Flash Booster costs £25 and should be available in stores and online in time for Christmas. To check if your camera is compatible, check here, and the rest of the details are here.
