Focus Areas

You can select the focus area that best suits the kind of pictures you intend to take. The selected focus area can be checked on the external LCD panel.

Normal focus area

Position the subject within frame in the focus fame in the viewfinder. If there are multiple objects in the focus frame located at various distances, the camera will focus the nearest object.

Spot focus area

The camera focuses at the center of the mark in the focus frame [O] in the viewfinder.

Manual Focus Mode (M)

The auto focus function can be cancelled, and you can focus manually.

1. Switch to “M” (manual focus mode).

Turn the focus mode selector lever and set it to “M” (manual focus mode). [MF]Appears on the top LCD panel.

2. Manual Focus Operation for Telephoto and Zoom lenses.

All Mamiya 645 AF Telephoto and Zoom lenses can be switched from Auto Focus to Manual Focus by sliding the focusing ring on the lens FORWARD until it clicks. When this is done, the “Auto Focus” inscription on the lens barrel is covered and the lens can then be focused manually. When the FOCUSING RING is set in this position the external LCD display on the top of the camera will show. It is not necessary to set the FOCUS MODE SELECTOR on the body to “M”. To switch back to auto focus, simply slide the focusing ring BACK towards the camera and the “Auto Focus” inscription on top of the lens will again be visible. This method applies to Mamiya 645 AF Telephoto and Zoom lens only.
