Instax square film is 2.4 inches on a side.

They claim that light loss is 3 stops so you treat the ISO 800 film as
ISO 100 to get correct exposure. The attachment also flips the image
because of that internal mirror. The front surface mirror is supposed
to be super reflective and clear.

The internal optics limits max aperture to f/4.

I have to wonder about the viewfinder issue, too, Larry. Looks like a
problem to me.

Cute but pointless, imho. Won't stop them from reaching their
Kickstarter target though! :-)
