Hitachi's 8MP budget compact — 1/2.5in CMOS, f/3.2 lens, 2.36in LCD, SD/SDHC, AAA power.
The Hitachi HDC-891E was an 8-megapixel budget compact sold under the Hitachi name through UK catalogue and discount retailers in the late 2000s. It sat above the HDC-881E in the licensed HDC line-up, a family of very low-cost point-and-shoot digicams that also included the HDC-571E and HDC-991E.
The archived instruction manual documents 8-megapixel capture at up to 3264x2448 pixels from a 1/2.5in CMOS sensor, a fixed lens with f/3.2 maximum aperture, and a 2.36in LTPS-TFT LCD for framing and playback. There is 16MB of internal memory with about 12MB usable, an SD/SDHC slot supporting cards up to 8GB, a built-in flash, and power from two AAA cells.
It is a basic automatic snapshot camera with no optical zoom and limited low-light ability, of interest mainly as a cheap entry into the late-2000s digicam look. The AAA-and-SD combination at least makes it painless to get running.
Check the AAA compartment for corrosion and weak contacts, which cause the sudden shutdowns these cameras are known for, and confirm the LCD is undamaged since there is no viewfinder fallback. Internal memory is too small to be useful, so factor in an SD or SDHC card up to 8GB.
