This page is about Korelle strut-folding cameras in 4×6.5cm, 4.5×6cm and 6×6cm formats. The 3×4cm Korelle is treated in a separate article.

The Korelle are strut-folding rollfilm cameras made by Kochmann from 1931 onwards. The name Korelle was first used on the 3×4cm model, which was followed by a full range of 4×6.5cm, 4.5×6cm and 6×6cm cameras. A 6×9cm Korelle was also released c.1934, but it was a regular folding camera, unlike the other models.

Korelle, 4×6.5cm Edit

The 4×6.5cm Korelle, released in 1931,[1] normally takes eight exposures on 127 film. The exposure chamber is removable,[2] to mount a plate holder or a film pack holder, presumably in 4.5×6cm format.

The camera pictured below has a Japanese Zuiko 7.5cm f/4.5 lens and Koho shutter (1–200, B, T). Its lens and shutter unit is not original, and was certainly taken on a Semi Olympus II.

Korelle P, 4.5×6cm plates Edit

The Korelle P, released in 1932,[3] is very similar to the 4×6.5cm camera, but takes 4.5×6cm film plates or film packs only. It has square ends and lacks the round film chambers of rollfilm cameras.

Korelle, 4.5×6cm and 6×6cm Edit

The 4.5×6cm and 6×6cm Korelle were released in 1933.[4] Their configuration is broadly similar to the 4×6.5cm model. The folding struts are mounted vertically instead of horizontally, and there is an additional door hinged at the front, to protect the lens and shutter unit. The viewfinder has a tubular shape, and is mounted on a hinged stand.

The 4.5×6cm model has manual film advance via a pair of red windows at the bottom of the back, protected by vertically sliding individual covers.

The 6×6cm model has an exposure counter disc inside the back, graduated from 1 to 12, driven by a feeler roller. There is a small thumb-wheel in the middle for manual reset. There is a single red window at the right end, to set the position of the first frame.

It seems that the numbers for 6×6cm exposures were not printed on the paper backing of 120 film at the time, hence the need for a special exposure counter. A similar device was later adopted on the Super Makinet Six and Prince Flex 6×6cm Japanese cameras.
