Mavica
Photography with vintage Sony floppy-disk cameras.

Sony Mavica FD-73
The MVC-FD73 was the basic model in the third-generation digital Mavica series from Sony, introduced in 1999. 3.5" standard floppy disks were used for storage, simplifying the transfer of images to a computer, helping make this a popular line of digital cameras in its era. The sensor resolution of 640×480 pixels is modest (suitable mainly for web or email uses), but helpful in keeping file sizes small (at the highest quality settings, a 1.4 MB floppy can hold a maximum of 20 JPEGs). The specifications of the lens were more generous: the f/1.8–2.9 4.2–42 mm lens give a 35mm equivalent coverage of 40–400 mm.
 

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.
