I was recently looking through André Kertész's collection "The Polaroids" and reminded of the grungy beauty of instant cameras. This motivated me to look up modern options, the best of which seems to be the Fuji Instax line.
If you've used these, what are your thoughts? I'm thinking of picking up either an Instax Square or Instax Wide to fool around with. There appear to be some downsides, including the price of a photo (something like $1/shot) and perhaps more importantly, an inaccurate viewfinder and limited controls.
Have you found these cameras to provide a fun experience?
