Even more sophisticated than the previous ProMavica MVC-5000 among Sony's early still-video cameras, the ProMavica MVC-7000 wrings the maximum possible resolution out of the technology (single television frames of analog scan lines) through the use of three sensor chips, as used in some broadcast television cameras. The intended market was certainly professional users such as journalists on tight deadlines, who could transmit images over telephone lines.
A proprietary Sony bayonet mount allowed a number of lens options to be attached, or Canon and Nikon lens adapters (with a substantial crop factor). Image storage is on enhanced Hi-Band VF (video floppy) media—miniature magnetic disks a bit over 2" square. The disks enforce a limit of 50 images in interlaced format or 25 in the superior non-interlaced "frame" mode.
While true digital cameras were in their infancy in the early 1990s, The MVC-7000 would represent the final generation of electronic imaging derived from television scan-line methods.
