The Fujifilm GA 645 Zi is a medium format autofocus rangefinder-style camera that exposes 6x4.5cm frames on 120 or 220 roll film. Introduced in the late 1990s, it was positioned as a compact, travel-friendly medium format option for photographers who wanted autofocus and a built-in zoom lens rather than a modular system.

At recent UK auction, hammer prices for the GA 645 Zi have landed between roughly £750 and £950, with the two recorded sales producing a median of about £850. The sales history is thin, so today's value is strongly condition-sensitive — clean, fully working examples with a quiet lens motor and clear LCD sell for more, while cameras with faults tend to be worth considerably less at saleroom level.
