One of my favorite (functional) cameras is the Fuji Instax 500AF.
After all the Polaroid film for the SX-70 expired. I stumbled upon a bunch of old Instax 200 and film at a camera show and started using them. It was fun but I wanted more control over the exposure.
Below is a comparison against the more common Instax 200/300.
The key difference is being able to turn off the flash, have longer exposure, and have tripod mount. The auto focus is also a great plus against the zone focus.
Instax 500AF on the left, Instax 200 on the right. The Instax 500AF was first announced in 1999, it was discontinued after a short run and became a cult classic. It is quite hard to find unless you are willing to pay some serious money from Japanese sellers.
Below are images from the Instax 500, capturing our daily life.
