Which films are used with this camera?

The clue is in the name. It uses APS film, but it's a dying format and is increasingly difficult to buy. When you find some buy just one roll until you've checked the camera works: APS cameras were crippled with a dreadful film transport design and it can be difficult to find one which still works. If broken, then just chuck the camera into the recycling bin: it's worthless and parts are not available.
