Olloclip is kicking off the series with a Super Wide lens and a Telephoto lens. The former gives you a wider field of view with the least amount of distortion of any of the company's wide-angle lenses, according to the lens maker. The latter gives you two-times magnification, but Olloclip said it gathers more light than its current 2x telephoto. Each is available for $100 (approximately £85 or AU$152) or $120 with an attachment clip.
