The Instant Back was one of the main reasons for me to get into the Diana system. I am quite into instant photography, including DIY solutions. If you are interested in more infomation about my instant photography, my site is here, but it's not complete yet. The Diana Back is a Fuji Instax Mini back, motorized, as all the Fuji Instax Mini cameras. As the Diana hardly covers the 6x6 format, there is a lens to put inside the diana to match the 6.2x4.6cm format of the Instax Mini Film and the new position of the film plane. Putting this lens and attaching the back is easy. The 800 ISO of the Fuji film work well with the Diana. The picture results were better than expected.

Its main features are:

75mm simple plastic menikus lens, ~F8, F16, F22, 3-zone focus 1-2m, 2-4m, 4m-, 0,35-0,7m in close focus mode. Pinhole setting F128
Shutter ~1/60, B
Size 128x117x104,  Weight 350 gr.
motorized Fuji Instax Mini back, takes 2 CR2 batteries, hook to block shutter in B position

The back is barely visible from this point of view.


Film compartment and the correction lens will be shown later when I have finished the film inside the camera.

Some pictures taken with black&white Instax film and the 38mm lens:

38mm, 2m setting, flash, F8, 1/60s, sharp image, a little bit of vignetting from the flash due to wide angle lens.

The Instant back gives good results for a camera with cheap plastic lenses. There is nearly no vignetting. The Instax film allows photos on dull days with normal shutter speed. No problem on sunny days as there are more F-stops.

A nice feature for your Diana. Instant fun.
