The Holga Instant is a Holga 120 
camera with an Instant back attached. There were several different Instan backs in the course of the Holga history. The first try was a back for Polaroid Pack 100 peel-apart film. With this back only a 6x6 cm (56x56mm to be exact) part of the film area is exposed, the rest remains black. The second try was a back for Polaroid SX70/600 integral film. Those I have seen had the same 6x6 exposure area, as the instant film plane was at the same spot where the roll film would have been. The main snag of this version is that the image is inversed. In Polaroid Cameras the integral film is exposed via a mirror. Without this bulky mirror the image is inversed.

The back shown here is for Fuji Instax Mini film. To cover the 46x62 mm image area, the film plane is a bit further away from the lens. In order to keep focussing right, there is an additional  lens which has to be attached in front of the Holga lens. This back is not motorized as the Diana Instant back. After the exposure you have to push the photo via a lever towards the rollers and then turn a crank handle to squeeze the photo through the rollers. This is quite easy and works well. No batteries are required and the price of the back was much lower than the price of a Diana Instant back.
 The main features of the Holga Instant are:

The Instant Back set, an Instax Mini Film back, a format viewer and a correction lens. If you take away the format mask to avoid vignetting, you have to secure the batteries with tape. On my backs (I have several of these) there was nearly no vignetting with the 6x6 mask staying inside.

Interior, 2-3m, flash, F20, 1/100s. Same photo as above, sunny setting. Exposure correct. More vignetting than above. This should not be the case, normally a smaller aperture should give less vignetting. Obviously the Holga aperture shades the edges of the photo. Maybe the aperture material is too thick. It's fine blades in ordinary cameras.

The Instant back gives good results for a camera with a cheap plastic lens. There is nearly no vignetting. The Instax film allows photos on dull days with normal shutter speed. No problem on sunny days with the F20 F-stop. The back is a good base for DIY backs on other film cameras, e.g. on old folders.

A nice feature for your Holga, but difficult to find. The backs were only marketed from Hongk Kong. But they are Instant fun.
