Special Features of the Mamiya

em-.-

The Mamiya M645 is a 6 x 4.5cm large-negative SLR that

is both extremely versatile and compact.

. Large-Negative Quality

The 6 x 4.5cm format offers approximately 3 times more area than the 35mm format. Moreover, unlike the 6 x 6cm square negative, there is little waste of the negative area.

For beautiful color enlargements everytime, the 6 x 4.5cm

format is the ideal format.

. Compact Design

Despite the large-negative it produces, the Mamiya M645 is designed to handle as easily as a 35mm SLR. Its compact size and light weight are perfectly suited for the ac-

tion photographer. It fits so well into one’s hands that it

becomes an extension of his reflexes,

Mamiya’s Moving Coil Electronic Shutter

Mamiya has developed a revolutionary Moving Coil Electronically Controlled Shutter for the Mamiya M645. Electrical consumption of this new shutter is approximately 1/10 that of previous electronic shutters. Furthermore,

consumption remains constant regardless of the shutter

speed being used. In addition to accuracy, long battery

life is assured by this new shutter.

. Large, Bright Viewfinder

It becomes easy to catch the peak of action when looking through the large, bright viewfinder. Because of the

Mamiya M645’s automatic diaphragm and quick-return mirror, the viewfinder never grows dim. It is always bright, ready for the next photograph.

. Interchangeable Finders

Lightweight, dual-function Waist-Level Finder S

A compact and lightweight finder which opens and closes with a single touch, the Waist-Level Finder S is ideal for copying, close-ups, low and high angle pictures, and working in dim light. Additionally, it is instantly convertible to an eye-level sports finder which accurately shows the f

ields for the 80,110,150 and 210mm lenses, allowing one

to easily follow the quickest action.

Prism Finder

The Prism Finder is well-suited for action photography.

Whether the vertical or horizontal format is utilized, focus-

ing and following action is as easy as on a 35mm SLR.

PD Prism Finder

The PD Prism Finder employs silicon cells for full-aperture, center-weighted readings. It is your assurance that every negative will be properly exposed.

a CdS Prism Finder with built-in meter

Accurate through-the-lens exposure measurement is

possible with the CdS Prism Finder which couples to the aperture of the lens and indicates the proper shutter speed to set on the camera.

Flatness of the Film Plane

Developed through Mamiya’s long experience as a manufacturer of 120/220 roll-film cameras, the Roll-Film Inserts for the Mamiya M645 keep the film perfectly flat for edgeto-edge sharpness. Inserts are available for 120 or 220

roll-film.

Multi-Coated Lenses

Mamiya-Sekor lenses have achieved world-renown as pro-

fessional lenses of exceptional contrast, high resolution,

clear definition, and excellent color balance. All the lenses

for the Mamiya M645, from wide-angle to telephoto, have

been multi-coated to maintain their high standard of per-

formance even under adverse lighting,

Unlimited Scope

A full range of accessories are available for the Mamiya M645 to assist the photographer in capturing virtually any type of image. Accessories include hand grips, interchangeable focusing screens, and auto extension rings

complete with meter coupling.

Multiple-Exposure Provision

Merely lowering the multiple-exposure lever allows the photographer to take as many multiple-exposures as he wishes. During multiple-exposures, the exposure counter does not move.

Mirror Lock-Up

The Mamiya M645 is designed to have minimal mirror shock; nevertheless, when it is necessary to completely

eliminate vibrations, all you have to do is lock the mirror in the up position. To do so, simply lower the mirror lockup lever. Mirror lock-up provision makes close-up and telephoto photography possible even at slow shutter speeds.

Two Shutter Release Buttons

The Mamiya M645 is equipped with two ideally located shutter release buttons, so that regardless of how you hold the camera, there is always a release button at your finger tips.

Built-in Delayed Shutter Release

Depth-of-Field Preview Lever

A single touch on the Depth-of-Field Preview Lever, which is ideally located on the camera body, stops the lens down to the preselected aperture for direct viewing of the depth-of-field.

Testing to See if the Camera Functions Properly

To release the shutter when there is no film in the camera, proceed as follows. [For detailed instructions on particular points, refer to the page number shown in parentheses.)

1. Insert a battery into the camera (p.21)

2. Set the multiple-exposure lever to “MULTI” (p.50). (If you have just purchased the camera and the vinyl tube is still on the take-up spool, there is no need to move the multiple-exposure lever.)

3. Set the shutter speed dial to any shutter speed other than the 0 red mark

(p.27)

4. Turn the film advance crank until it stops.

5. Align the shutter release lock ring with the white dot and release the shutter

(p.30). When ready to load the camera with film, return the multiple-exposure lever to

its normal position. If this is not done, the film will not advance.

If the shutter is released without a battery in the camera, the mirror will lock in the up position. To return the mirror to its normal position, depress the battery check button (21) as far as it will go.

If the shutter is released with the shutter speed dial set to the red 0

the mirror will lock in the up position. To lower the mirror, turn the shutter speed dial in either direction (B or 1/1000 sec.). At times it may be necessary to rotate the film advance crank two full turns to cock the shutter when an empty take-up spool (without its original vinyl tube) is

in the camera.
