Fuji 800
A photographic film and semiconductor component sharing a name, not a single device
Overview
"Fuji 800" refers to multiple distinct products from Fuji-affiliated companies, not a single vintage technology model. The name appears in three unrelated contexts: as a photographic film marketed for low-light shooting without flash, as the MBM29F800 — an 8 MBit flash memory IC manufactured by Fujitsu, and as high-power IGBTs rated at 800 amps and 1200 volts used in industrial applications. Despite the shared name, these products serve entirely different markets and technologies.
Ken Rockwell noted the photographic version's wide exposure latitude, stating that even five stops of overexposure produced indistinguishable results in prints. The IC version shares design similarities with the AMD AM29F800 and is functionally equivalent to parts from Macronix and ST. There is no evidence of a unified consumer device or vintage equipment model named "Fuji 800."

Context
Ken Rockwell used Fuji 800 film as a general-purpose film suitable for dim lighting without flash before transitioning to digital with the Nikon D1H. He emphasized its forgiving exposure characteristics, noting no visible difference in prints between correctly exposed and heavily overexposed shots.
