Half-frame camera

As a half-format camera is called a camera, the ( so Kleinbildfilm ) usually used conventional 35 mm film, the images but not 24 × exposed in the usual small format 36 mm, but for the original silent film cinema format 18 × using 24 mm. This is therefore also known as a half-size.

The image number is doubled compared to the small format to 24 (instead of 12 pictures), 48 (instead of 24 frames ) or 72 ( instead of 36 images). With special black and white thin film is achieved up to 114 images in a regular-sized camera.

From Yashica the half format was falsely advertised as a double format like because of the number of images. The term double format is actually for the regular 24 × 36 mm format in contrast and comparison to the 18 × 24 mm half-size.

Models

In the history of photographic technology has been repeatedly and early experiments with half sizes.

To a boom in the 1960s resulted in the publication of the Olympus Pen F ( 1963), followed by a whole series (Pen FT, Pen FV etc.). Other manufacturers such as Minolta, Canon and Konica then developed his own half-size models.

The different models of the Pen series ( viewfinder cameras and SLRs ) Olympus applies despite any set half-size range than the manufacturer with the longest production time (approx. 1960-1983 ). In addition to the cameras, the Olympus Pen F series - which are considered the best-known - there are SLR cameras with interchangeable lenses from other manufacturers. However, these are usually conversions of regular cameras for special purposes or small series regular in the half- SLR format. The Yashica SLR series in turn each have one of the fixed zoom lens.

It is worth mentioning is the Minolta Electro- zoom X ( Minolta 16 Electro- zoom X ), which presented in 1968 as a design study for an SLR, but it was never commercially produced. She used an even smaller half-size of 12x18 mm to 16 -mm film (10 × 14 mm) should be packed in Minolta 16- mm cassettes.

Conversions and special structures exist about for investigating authorities and the police. In addition, this large capacity trays have been used to some extent.
