Verdictwhich should you buy?

Instax Wide 400 — Groups, Landscapes & Anyone Who Wants Bigger Prints: The Wide format transforms instant photography — larger prints with proper presence. The right choice for groups and landscapes.

A6400 — Content Creation & Vlogging: The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
