Mamiya 645 AF

This was Mamiya betting that medium format could autofocus and not feel like a compromise. The 645 AF arrived in 1999, and the pitch was simple: a 6x4.5 negative with the handling of a 35mm SLR. Grip on the right, motorized film advance, an autofocus motor, a focal-plane shutter that runs all the way up near 1/4000. For anyone who had been wrestling a waist-level finder and a hand-cranked back, picking this body up was a jolt.

It handles like an oversized 35mm. You hold it to your eye, you look through the eye-level prism, and the camera tells you what it is doing. The viewfinder is bright, and the metering is read through the eye-level AE prism finder, with spot and averaging patterns, plus program and priority auto modes alongside full manual if you want them. That feature set was ordinary on a 35mm body in 1999. On a medium-format camera it was rare enough to be the reason you bought one. The autofocus is single-point and deliberate, not fast by modern standards, but it locks and it is accurate. Loading is by interchangeable back, so you swap film mid-roll or carry a second back loaded with a different stock.

The build is plastic-shelled over a metal core, lighter than the all-metal Mamiya bodies that came before it. That bothers people who grew up on the RB67. It should not. The lighter weight is the point; this is a camera you carry to a wedding and shoot from morning until the last dance without it wrecking your shoulder. The shutter has a clean mechanical clack, sync at 1/120, and the whole package runs on common AA cells, which matters more on a job than the spec sheet lets on.

The honest weakness is the dependence on electronics. No battery, no camera. There is no mechanical fallback speed, so a dead pack of AAs in the cold strands you until you swap them. The early autofocus also hunts in low contrast, and the native AF lens lineup was smaller than the long-running manual 645 catalog, which some shooters held against it. People who want bulletproof simplicity reach for an RB67 instead and accept the bulk.

Today it sits in the affordable-medium-format conversation, cross-shopped against the Pentax 645N and the Contax 645. The Contax carries a cult following and Zeiss glass, and its prices reflect both. The Pentax has its own loyalists. The Mamiya tends to be the cheaper way in: autofocus, a real meter, interchangeable backs, and a system that later grew into the Mamiya 645 AFD. The digital-back capability came with that later AFD line, not this original film-only AF body. Portrait and wedding shooters still load these because the negatives are big and the workflow is fast.

One practical note. The in-camera meter, averaging or otherwise, reads even light fine, but a backlit portrait or a bright sky will fool it. Take an incident or spot reading from the Zone Light Meter app, place your subject's shadows on the zone you actually want, and set the aperture from that rather than trusting the camera to guess. On contrasty work, deciding exposure yourself beats handing it to the prism.
