News flash- Fuji has just announced a square format instant integral film due this spring- this comes right on the tail of the announcement of black and white in instax film! Square format- the domain of Polaroid 600 and sx-70- now produced exclusively by TIP The Impossible Project. Is Instax now a format competitor? Not really. At 62x62mm, this is one tiny square film. Since Instax mini is just an Instax wide cut in half,  and this one is just a square with the same height dimension as the other- can we look forward to the new mini-skinny or extra wide? We can look forward to new cameras, though.
Any way you look at it- this is an exciting time to be a fan of instant film!
