At $89.99, the latest Go is the most affordable Polaroid camera available, with film that costs just a little more than Fujifilm’s Instax Mini shots (a 16-sheet pack runs $21.99). The new Go sports a few upgrades over the last-gen model, including USB-C support, and Polaroid claims the camera produces clearer stills than its predecessor. Photos are slightly brighter, though the original Go produced warmer images that felt more true to life. Still, the photos are charming in the way only a Polaroid photo can be. Contrast and color saturation levels are still low, but in a way that exudes the vintage, almost dreamy look of the photos taken with the Flip.
