Konica produced Sakura film (later simply rebranded to ‘Konica’). They were the second-largest film producer in Japan after Fujifilm. As well as their own films, they produced films for lots of third parties. They had every good business reason to encourage rapid winding and exposure of their product.
In 1979 Konica produced a landmark camera with a winder.
It was not the first SLR with a built-in winder (that was the unmetered Minolta SR-M), but the FS-1 was the first automatic SLR to feature the winder integrated into the body (rather than bolted on the bottom). It also eliminated the manual wind-on lever. With a generous grip for the right hand to house the alkaline batteries required, It had a profile that was radical at the time, but which now seems rather familiar.
