Overview — Fujifilm GA645

The Fujifilm GA645 is a medium format film camera that brings a compelling combination of automation and image quality to the 6x4.5cm format. Built around a fixed lens system, this camera is designed for photographers who want the richness of medium format film without the bulk and complexity of traditional medium format bodies. At 815g and measuring 166mm x 110mm x 66mm, it occupies a genuinely compact footprint for its format class, making it a practical choice for travel and street work.

The autofocus system combines Phase Detection and Contrast Detection for reliable subject acquisition through a single focus point. ISO sensitivity spans from 25 to 1600, giving the camera a broad range of film compatibility from slow, fine-grained stocks to faster films suited for lower light. Flash capability is handled by a built-in pop-up flash with a guide number of 12, supplemented by a Standard ISO hot shoe for external flash units.

The camera runs on two CR123A 3V lithium batteries and features a Monochrome LCD display for settings reference. The body is constructed from plastic with a metal internal frame, and no weather sealing is present. The optical viewfinder provides straightforward framing, keeping the shooting experience direct and uncluttered.
