Mamiya 645 AFD II

Mamiya put autofocus into the 645 line in the 1990s, and by the time the AFD II arrived in 2005 the whole point of the body had shifted. It was no longer just a 6x4.5 film camera. It was the front half of a digital system. Bolt a Phase One or Leaf back onto the rear and the same body shot tethered in a studio; swap it for the film magazine and it shot 120 again. That dual life is the entire reason this camera exists, and it is why you still see them on used shelves at prices that have nothing to do with how good they are.

In the hand it feels like what it is, a big plastic-and-metal SLR built around a prism finder rather than a waist-level hood. The viewfinder is bright and large the way medium format finders should be, and the autofocus works, which is more than you can say for most film cameras of any era. Focal-plane shutter, 30 seconds down to about 1/4000, flash sync at 1/120. That fast top speed is unusual for the format and lets you shoot fast lenses wide open in daylight without a leaf-shutter compromise. The film back is interchangeable and detaches with a dark slide, so you can swap backs and stocks between rolls the way studio shooters always have.

The built-in TTL meter is genuinely capable, with selectable spot and averaging patterns plus aperture-priority and manual exposure. Switch it to spot and you can read a bride in white against a dark church and place that white exactly where you want it, which is the kind of control a single averaging cell never gives you. Where a handheld reading still earns its keep is in confidence and consistency: in a backlit or harsh high-contrast scene, an incident or spot reading from the Zone Light Meter app lets you set the shadows on the zone you want and ignore whatever the body is averaging behind the prism. Use the in-camera meter for speed, reach for the app when the light is trying to fool it.

Build is the honest weakness. These are electronic bodies through and through, dependent on batteries and on a circuit board that was never designed to last forty years. When an AFD II dies it usually dies for good, because parts are scarce and nobody is making more. The autofocus is also slow and noisy by any modern standard, fine for a posed portrait, hopeless for a moving toddler. You buy this body knowing it is a tool with a service life, not an heirloom.

Who shoots it today. Wedding and portrait photographers who want autofocus and a big negative without paying Contax 645 money, and digital-back owners who picked up the film body for next to nothing. The Contax is the rival everyone cross-shops, prettier glass and a cult following, but a Contax 645 with a dead shutter is a paperweight and the Mamiya can be had for a third of the price. If you want a 645 autofocus film camera that actually focuses and meters, and you accept that the electronics are mortal, this is the sensible buy. It was built to work, and most of them still do.
