The Yallu Flex (sometimes referred to as "Yalluflex") was influenced by the Zeiss Contaflex, which was available in Japan at a very high price and was of particular interest in view of the patchy availability of roll film. The Yallu Flex was ingeniously and elegantly designed and was well equipped and appealingly advertised, but in the end it was never offered for sale: it is said that potential dealers were unimpressed by the prototypes that they received. About fifty were produced.
Yallu Optical survived the disappointment, renaming itself Aires and bringing out 120 TLRs and other cameras.
- Or perhaps after the American pronunciation of the name of this river (in Chinese Yālǜjiāng, 鴨綠江, 鸭绿江; in Korean Amnokkang, 압록강; in Japanese Ōryokkō 鴨緑江). See the English Wikipedia page about the Yalu River.
