Fuji GA645Zi Professional
Hold this thing to your eye and half-press it and your hands tell you it is a consumer compact. Then the scans come back and you remember it laid down a 6x4.5 negative, nearly three times the area of a 35mm frame, sixteen of them to a roll of 120. The GA645Zi is a medium-format camera that operates like a point-and-shoot, and it commits to that all the way down. Autofocus. Auto film loading. Auto wind. A little zoom Fujinon that runs from a mild wide to a short portrait length and reads out its setting on an LCD up top. Nothing about using it says you are shooting a negative this big until you look at the film.
The Zi is the zoom member of Fuji's GA645 family. The plain GA645 and the wide GA645W carried fixed lenses, and the Zi gave up a little resolution at the corners to let you reframe without walking. The glass is good enough that the people who shoot one never complain about it. The finder is the clever part. It projects bright frame lines that change to match wherever the zoom is sitting, with automatic parallax correction, so you read your composition off a window that reshapes itself as the lens moves, with a center mark that doubles as the focus and metering point. The autofocus throws a distance reading onto the finder so you confirm before you trip it. The leaf shutter runs from four seconds to about 1/700 and it is nearly silent, a soft electronic snick instead of the mirror slap of a 645 SLR. You can shoot people across a quiet room and they keep talking.
Metering is built in, driving a program mode plus aperture priority, with a compensation dial for when you want to argue. It reads center-weighted, and like every averaging meter it gets talked into the wrong answer by a bright sky or a backlit subject. Put a window behind someone and the face goes dark. That is the moment to stop trusting the body. Pull a spot or incident reading from the Zone Light Meter app, decide which zone the shadows belong on, dial that into the compensation, and let the negative carry the rest. Color print film hands you the latitude to make a placed reading hold.
The honest weakness is power. It runs on two CR123A lithium cells, and when they die the camera is inert, because focus, wind, meter, and shutter all draw from the battery. Carry a spare and check it before a shoot. The build is the other catch. The whole thing is electronic and plasticky in a way the metal Fuji rangefinders never were, so a serious fault usually means the body is finished rather than a service-it-forever proposition. People do not repair these. They source another clean one.
Today the GA645Zi sells to photographers who want medium-format negatives without the meter, the loupe, and the tripod ritual, and who do not mind that it looks like a bridge camera from across the street. The usual cross-shop is a Mamiya 645 or a folder like the GS645, and the Zi gives up some of that mechanical romance in exchange for being fast and unfussy. The practical upshot is that it is the 645 you actually pack for a trip instead of leaving home because it was too much gear to carry, which is exactly why clean ones still get hunted.
How the app handles this body
- Metering: Take an incident or spot reading in the app and place your shadows on a chosen zone, then dial that exposure in. On a body with no meter, or one whose cell has drifted with age, the app is the meter you trust.
- Leaf shutter: The shutter sits in the lens, so it syncs flash at every speed instead of topping out at a body X-sync. Daylight fill stays open at any aperture, and the app's shutter ladder covers the leaf range.
