The Yashica Sound 20XL is a Super 8 camera built for low-light shooting. It pairs an ultra-fast f/1.1 zoom lens with a 230° XL shutter and a non-reflex viewfinder that helps maximize brightness. It recognizes 40 and 160 ASA Super 8 film stocks. It runs on 6×AA batteries (the 9V compartment is only for sound functions, which are no longer usable).
