When choosing an instant camera, consider factors such as film format, features, and budget. Instax-type instant cameras typically use Fujifilm Instax film, available in various formats such as Mini, Wide, and Square, each offering different print sizes and aspect ratios. Additionally, consider features such as exposure control, autofocus, built-in flash, and creative shooting modes to suit your photography style and preferences. Finally, evaluate your budget and choose a camera that offers the best combination of features and value for your needs.
