Fujifilm’s $116.99 Instax Mini 41 is the long-awaited follow-up to the Mini 40. The updated model retains the retro design found on the prior model but introduces parallax correction, a feature borrowed from the Instax Mini 12 to help users avoid off-center shots when taking close-ups.

The two cameras are nearly identical, aside from the design, with the same solid photo quality and feature set. Both battery-powered options turn on with a simple twist of the lens, and each comes equipped with a selfie mirror, a close-up mode, and a flash (which cannot be disabled).
