If you’re looking for an advanced analog instant camera, Fujifilm’s Instax Mini 99 is one to consider. At $234.95, Fujifilm’s latest instant camera is not as affordable as the Instax Mini 12 or the Mini 41, but it’s certainly a step up from the one-button point-and-click cameras given it has multiple brightness settings, focus zones, color effects, and even two shutter buttons for greater creative control. The camera even comes with a tripod socket, an aluminum extension column, and a Sports Mode designed to further reduce blur when capturing fast-moving subjects.
