Olympus's 1.3MP entry Camedia (D-100 in US) — fixed 35mm-equiv f/2.8 lens, SmartMedia, AA power, 2001.
The Camedia C-1 was Olympus's entry-level digital compact of 2001, sold in North America as the D-100 (marketed there under the Camedia Brio label). It should not be confused with the separate C-1 Zoom, which added an optical zoom lens; the plain C-1 is the fixed-lens base model that put the Olympus badge on a first-digital-camera budget.
It combines a 1.3-megapixel 1/3.2-inch CCD with a fixed 35mm-equivalent f/2.8 lens that stops to f/8, producing 1280x960 images in SHQ/HQ or 640x480 JPEGs. Shutter speeds span 1/2 to 1/1000 second, there is 2x digital zoom, a 1.5-inch colour LCD and a built-in flash. Storage is SmartMedia (an 8MB card was typically supplied) and power comes from two AA cells, NiMH rechargeables or one CR-V3.
Today the C-1 trades almost entirely on Y2K digicam nostalgia: 1.3 megapixels of early-CCD colour in a small, simple body. It suits collectors and lo-fi digital enthusiasts rather than anyone needing practical image quality, and AA compatibility makes it one of the easier twenty-five-year-old digitals to actually switch on.
SmartMedia is the gatekeeper on the used market — cards are discontinued and readers scarcer, so an included card and a means of transfer (USB cable or card reader) decide whether the camera is usable at all. Check the LCD for fading, the flash for charge, and the battery contacts for corrosion, a common fate of AA-powered compacts stored loaded.
