1974: The average 35mm 'compact' camera was heavy, bulky, needed big and deep pockets. For example the excellent Canonet G III 19 measured 120x75x60mm and weighed 630 grams. At Photokina that year, MINOX stunned the industry with the 'MINOX 35'. Only 100x61x31mm and 200 grams. Retractable lens and superb image quality.
The typical Minox 35mm camera was 1/3rd of the price of the professional Minox 8x11mm cameras. For example the Minox GT sold twice the number of the Minox C but was 1/3rd of the price.
