The camera has a very peculiar design. It is surprisingly compact and feels toy-like, which isn't far from the truth— it has only one shutter speed of 1/50s and an aperture of F11.

With such characteristics, which do not allow for exposure adjustments, the only option is to use the most optimal film for the photographic conditions. It also helps if the film has maximum photographic latitude.

However, this camera is designed for type 127 film. The frame format is 30x40mm. There aren't many options available, and the cost of the film is not budget-friendly either.

A solution was found. The holes on the back cover were sealed with foil to prevent light from entering from the outside.

And regular 35mm perforated film was loaded. The film cassette wouldn't fit, so the film was simply wound onto the spool. 

The winding was done "by eye"—approximately one full rotation.

The film is fully exposed— the image also extends onto the perforation. Thus, the frame measures 30mm horizontally and 35mm vertically.

The lens allows for focusing— thankfully, they didn't simplify the design here.

I took a couple of test shots of landscapes and a portrait from a distance of 1.5 meters.
