Sony Mavica FD-91 The MVC-FD91 from Sony was the top-end model in the second generation of digital Mavica cameras, introduced in 1998. It offered a startling 14x optical zoom range more typical of consumer camcorders (which it resembled), of 5.2–72.8 mm at f/1.8–3.2. This gives a 35mm equivalent range of 37–518 mm. The maximum image resolution was 1024×768 pixels. It used standard 3.5" computer floppy disks for storage. At the maximum image-quality settings, a 1.4 MB floppy can store about eight images.
