Looking a whole heap more professional than a DIY ring-flash, Photojojo's $40 flash is light in two ways: it weighs just 700 grams, and uses the light from your existing flashgun to illuminate your photos evenly, and strongly.

It doesn't have its own lights like expensive ring-flashes, but if you're not willing to fork out double or even triple the price of Photojojo's F160, then it's a nice compromise. [Photojojo via WIRED]
