The Fujifilm GA 645 W is a medium-format autofocus rangefinder-style camera that shoots 6×4.5 frames on 120 and 220 roll film. It was introduced in the 1990s as the wide-angle variant in Fujifilm's GA 645 series, aimed at photographers wanting a compact medium-format body with a fixed wide lens.

At recent UK auction, hammer prices for the GA 645 W have been limited, with a 2024 saleroom result of £460 and an older 1999 record at £517 — these are wholesale hammer figures, not retail. With only two data points the range sits at £460–£520, and in today's market condition, working electronics and a clean lens are the main value drivers when assessing what a GA 645 W is worth.
