Nostalgia is a powerful thing. Take a look at the Polaroid OneStep+ for example. The original OneStep was released in 1977 as an analogue, instant camera; the 2018 version is still analogue and spits out your prints in no time, but it connects to your smartphone over bluetooth to give you a few extra options. You can use your phone as a remote shutter, for example, or create double exposures in the accompanying app. You can also trigger the shutter by clapping your hands – which could be equal parts useful and annoying – or use the app to put the camera into full manual mode. So it's vintage, but with a modern twist.
