Inspired Photo Gear is steadily augmenting its range of photography accessories, adding two new lighting modifiers to its Faith lighting stands and Lollipod multi-use supports. As well as stocking the Lightblaster, which we looked at and loved a few months ago, it's now selling the RoundFlash modifier, too. The RoundFlash is a lightweight (230g) and portable collapsible ring light and soft box that can be used either on- or off-camera. On-camera, you fit it around your lens with your hotshoe-mounted flash feeding into it. Off-camera, you mount your flash on a lighting stand and then attach the RoundFlash to it.
The RoundFlash modifier fits around lenses with diameters upto 10cm and is perfect with lenses designed for portraiture (it is a ring light, after all) for example Canon's 85mm. If you've an especially small lens, try adding a lenshood to create more stability.
There's even a video demonstrating just how fast it is to set up:
The RoundFlash is available from Inspired Photo Gear for a special introductory price of £92.95. If you don't want to spend on a ring light when you already have a set of speedlights, it might be worth a look.
