Casio Exilim EX-Z40 — 4MP slim metal compact with 3x zoom, 2004 Exilim Zoom series
The Casio Exilim EX-Z40 is an early Exilim Zoom compact that Casio launched in February 2004, at a time when slim all-metal digital cameras with a genuine zoom lens were still a novelty against the fixed-focal-length Exilim Card models that preceded them.
It has a 4-megapixel sensor paired with a 3x optical zoom lens, a rear LCD for composition and review, and stores images on SD/MMC cards. The camera runs on Casio's NP-40 rechargeable lithium-ion battery and features a metal chassis typical of the early Exilim Zoom range.
For 2004 the EX-Z40 stood out mainly for combining Casio's signature slim metal body with real zoom flexibility, at a time when most ultra-thin compacts sacrificed zoom range entirely; resolution and low-light performance are modest by later standards.
As an early-2000s model, used examples are now largely collector or casual pieces; check the NP-40 battery still accepts charge, confirm the zoom lens is free of dust or fungus, and test the LCD hinge and screen for the fading common on cameras this age.
