PetaPixel has two articles about hacks on top of the Fujifilm Instax instant camera.
An Instax Camera with the Leica M lens: a prototype using the SQ10 as a base, where the M lens mount replaces the lens, to produce square images. The hybrid model of small sensor and Instax printer make this work, as the coverage of an M lens is insufficient for even Instax Mini. Still the image quality is seriously limited by the quality of the sensor and the “printer”.
Combining a Hasselblad 500 and an Instax Mini 9: the Instax mini act as a film back for the Hasselblad.
We were really happy with our first tests. The full frame of the film is exposed and the images are sharper than we’ve ever seen on this type of film. There are still a few ongoing issues with light leaks and with focusing because of the slight difference in focal plane length.
Interesting to see the creativity in that area.
