  1. Weights: 1,730 g without batteries is the 645 AF manual's figure and kakaku.com's AF specification, and the dealer sheet for the AFD III repeats it; the AFD III manual's table (ManualsLib) prints 1,780 g. Kamerastore's shop pages give 1,554 g and 142 × 152 × 134 mm for the AF and 1,060 g and 142 × 153 × 131 mm for the AFD III, which do not match the manuals and are not used here.
  2. The mount is the 645 AF bayonet of 1999, not the 1975 M645 bayonet. The manuals list it as compatible with the M645 mount: the manual-focus lenses go on the AF bodies directly, with manual focus, focus confirmation and stop-down metering (Av or M), but AF lenses do not fit the manual-focus bodies. Mamiya's own mount adapter is for Hasselblad V lenses (English Wikipedia lists the black HBB and silver HBW adapters), with the same stop-down limits.
  3. The AFD II release date is disputed: 29 July 2005 (kakaku.com) or September 2005 (The Photo Nerd). Japanese and English Wikipedia give only the year.
  4. The end of AFD III production is not given by any source consulted; the 645DF of 2009 succeeded it for digital only, and the AFD III stayed the film-capable body.
  5. Single-source claims: the 1.2 fps figure for the AF (its manual, repeated by Japan Camera Hunter and The Photo Nerd for the AFD); the factory upgrade needed for an original AF to take digital backs and the D-lens incompatibility of the AF and AFD (Flickr group discussion); the 2008 coloured-body and Phase One badge details beyond Wikipedia.
  6. No production figures are published for any of the four bodies.
How to tell them apart (expand)
  • Model name on the front of the prism housing: 645 AF, 645 AFD, 645 AFD II or 645 AFD III (Phase One 645 AF on the rebadged AFD III)
  • Fixed prism with integral grip and built-in motor: no removable finder, no crank, no separate winder, which separates it from every manual-focus 645
  • 645 AF bayonet with electrical contacts; AF lenses have no aperture ring and are set from the body's dials
  • AF and AFD: T on the mode dial and a mechanical mirror-up lever. AFD II and III: CF on the mode dial, electronic mirror-up, AFL button. AFD III only: three AF points and the HM402 magazine

645 AF:

  • '645 AF' on the front of the prism housing; no 'D' in the name
  • Mode dial with a T (time) position as well as B; the AFD II dropped T
  • Mechanical mirror-up lever on the body side; the AFD II moved mirror lock to a button and menu
  • Fixed prism with 0.71× magnification and built-in diopter adjustment; no waist-level finder fits

645 AFD:

  • '645 AFD' on the front of the prism housing
  • Outwardly the 645 AF: same T position on the mode dial, same mirror-up lever (Japanese Wikipedia: 外観はほとんど初代から変更なし)
  • Digital back status shown on the body's external LCD when a back is fitted (camera-wiki)

645 AFD II:

  • '645 AFD II' on the front
  • CF position on the mode dial for the 36 custom functions; no T position, B is electronic
  • Electronic mirror-up by button instead of the mechanical lever; separate AFL (autofocus lock) button
  • Self-timer on the shutter-release mode selector

645 AFD III:

  • '645 AFD III' on the front; the Phase One-badged version reads 'Phase One 645 AF'
  • Three selectable AF points (centre, left, right, or auto) instead of the single centre point
  • Mirror-up on the shutter-release lock, self-timer access reversed, and a mirror-up delay custom function
  • Sold with the HM402 roll film magazine; the earlier HM401 fits but advances more slowly

Serial-range notes

Numeric, no date-code prefix documented
Mamiya Repair's date-code page lists the two-letter year/month prefix for the 645 Super, Pro and Pro TL, the Mamiya 6/7 and the RZ67 Pro II and says it does not service the 645AF/AFD; no source consulted documents a dating scheme for the autofocus bodies.

What reviewers say

History

The 645 AF of September 1999 is Mamiya’s first autofocus camera and a clean break from the manual-focus 645 line it replaced in the catalogue. Where the 645 Super, Pro and Pro TL were modular kits of body, finder, crank or grip and holder, the AF is one piece: a fixed metering pentaprism, a motor for advance and autofocus, and a grip holding six AA cells are all built in, and only the film magazine comes off. The lens mount is new, a bayonet with electrical contacts that camera-wiki calls the 645 AF mount, on which the AF lenses have no aperture ring and take their aperture from the body’s dials. The manual-focus lenses of 1975 onward mount on it directly: the manual’s own specification lists the mount as “compatible with M645 mount (manual focus confirmation, focus aid, stop-down exposure metering)”, and a microprism screen (#314474) is sold for them. What they lose is automatic diaphragm coupling, so the metering is stop-down in Av or M, and the reverse is not possible at all, since an AF lens does not fit a manual-focus body. Mamiya’s only mount adapter for these bodies is the one for Hasselblad V lenses, which work under the same stop-down limits.

The specification is the same across the four bodies. The shutter is an electronically controlled vertical metal focal-plane unit running 30s to 1/4000, in 1/8 steps under AE and 1/2 steps in manual, with X sync at 1/125 and a hot shoe and PC terminal; when the magazine comes off the curtains open, and they close again when one is fitted. The fixed prism shows 94 per cent of the 56×41.5mm frame at 0.71× with a built-in diopter, and meters centre-weighted, spot or an automatic blend of the two from EV 2 to EV 18 at ISO 100 with an f/2.8 lens, in aperture-priority, shutter-priority, program and manual, with ±3 EV compensation and AE lock. The 120 magazine gives 16 frames and the 220 magazine 32, each back carrying its own LCD, ISO setting from 25 to 6400 and a CR2032 cell so that it remembers its frame count off the camera. Continuous advance is about 1.2 frames per second on the AF, and 2 frames per second on the AFD III with its HM402 magazine. The manual gives 153 × 128 × 184 mm and 1,730 g without batteries for body, prism and magazine.

What changed is mostly electronics. The 645 AFD of December 2001 added Mamiya Serial Communication so that a digital back can exchange data with the body and show its status on the body’s LCD; Japanese Wikipedia and the Ishii Camera summary both say the outside is otherwise the first camera, and that is where the D in the name comes from. The AFD II of 2005 (29 July by kakaku.com, September by The Photo Nerd) brought a quieter focusing motor and a new algorithm, a CF position on the mode dial with 36 custom functions including a choice of 1/2 or 1/3 stops, an electronic mirror-up by button in place of the lever, an AFL button, and the loss of the mechanical T setting. The AFD III of April 2008 moved mirror-up to the release lock, added a mirror-up delay function, three selectable AF points where every earlier body had one at the centre, the HM402 magazine and acceptance of Ni-Cd and Ni-MH cells. Phase One sold the same camera as the Phase One 645 AF, and in September 2009 the two companies’ 645DF, on the same mount, gave up film backs altogether, which leaves the AFD III as the last film-capable body on the mount. Kakaku.com prints ¥315,000 for the AFD II body and ¥397,000 for the AFD III; no list price was found for the AF or AFD, and Greenspun’s January 2002 figure of about $3,500 is for an AFD with the 80mm f/2.8 and a back.

To identify one, read the prism front: 645 AF, 645 AFD, 645 AFD II or 645 AFD III. An AF or AFD has T on the mode dial and a mechanical mirror-up lever on the body; an AFD II or III has CF on the dial, a mirror-up button and an AFL button; only the III has the three-point AF selector and ships with the HM402. Which backs and lenses a body talks to is the real dividing line, and the Flickr group’s thread is the only source that lays it out: an original AF needed a factory upgrade to take digital backs and does not drive the later D-series lenses, the AFD II works with the D lenses and all backs, and the AFD III with everything short of the leaf-shutter LS lenses made for the 645DF. That is a user forum and is carried here as such.

Buying advice from the reviews turns on the autofocus and the batteries. Every reviewer describes the body-driven AF as slow and loud, and the single centre point on the AF through AFD II as forcing focus and recompose; Fstoppers calls continuous AF unusable, while Japan Camera Hunter finds it good enough for street candids. The film back needs its CR2032 to hold settings and its ISO buttons are small and stiff, so check the back’s LCD and that the ISO changes. The body’s six AA cells run everything, and Greenspun quotes 340 rolls from lithium cells. Mamiya Repair’s date-code page does not cover these bodies and says the shop does not service them, so there is no published way to date a serial, and no production figure exists for any of the four.
