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.
