Unlike the Mini 12, the Evo comes with a few extra features that can help you capture better photos. For example, you can disable the flash, leverage the 3-inch LCD screen as a viewfinder, and adjust the brightness of a print — a helpful feature, given Evo doesn’t capture dark environments well. The camera’s dials also let you apply various lens options and effects, from retro filters to monochrome shades, and you can even take app-based remote shots, allowing for better seflies and more photographic control.
