I miss Polaroid! I’ve been stockpiling some old film, but I’m always afraid to use it and run out for good. It looks like the Instant Back attachment for the Diana+ Lomo camera might serve as an able replacement. The Instant Back attaches to the Diana+ and provides you with instant (90sec) print outs, just like Polaroid. It looks like it will do until the Impossible Project begins manufacturing their new film for the old cameras.
Of course, after Scott’s post below, a purchase of any other type of camera besides the 5D seems pointless. I have to start saving now!
