However, there are notable drawbacks to the Shot 3 Retro. The resulting prints aren’t nearly as crisp or clear as those taken with a smartphone, for one, nor were they as clear or sharp as what you might get with the Evo or Mini 12 (some even have an excessive pink tint). The Shot 3 Retro doesn’t store images the way the Evo does, either, which means you can’t decide whether you’d like to print them later. It’s also noticeably heavier than the Evo and, frankly, nowhere near as stylish. Nonetheless, if you don’t mind compromising on photo quality and want a relatively affordable hybrid camera with fun app features, the Shot 3 Retro is a good choice.
