Vivitar's 7MP budget digicam — 4x digital zoom, 2.36in LCD, SD/MMC storage, rechargeable Li-ion battery
The Vivitar ViviCam 7100s was a 7-megapixel budget digital compact from the late-2000s ViviCam range, sold through discount retail in the US and UK. The trailing 's' matters when identifying it: Vivitar model numbering of this era reused base numbers across distinct cameras, and listings also exist for a plain ViviCam 7100, so the designator should be matched exactly.
Retail specifications list a 7.0-megapixel sensor, a 4x digital zoom with no optical zoom, and a 2.36-inch LCD for framing and playback (some retail copy rounds this to 2.4 inches). Storage is via SD/MMC cards, and unusually for the cheap end of the range it shipped with a rechargeable lithium-ion battery, USB cable, strap and case rather than running on disposable AAs. Deeper specifications are thinly documented, so figures beyond these should be treated cautiously.
In use it is a standard auto-everything budget digicam: fine for well-lit snapshots, slow to respond, and noisy indoors. Its higher pixel count over the 5MP ViviCams brings little real quality gain from the same class of small sensor, so buyers today choose it for the digicam aesthetic and low price rather than resolution.
The proprietary lithium-ion battery is the key used-market check: examples without a battery and charger are hard to revive cheaply, so favour complete bundles. Confirm the camera charges and holds power, writes to an SD card, and that the comparatively large LCD is free of cracks and dead rows. Untested body-only listings are best valued as parts.
