Mamiya M645 Pro TL Instructions Manual

Instructions

Congratulations on your purchase of the Mamiya 645 PRO TL

Mamiya pioneered the 6 x 4.5 film format and introduced the world’s first 645

SLR in 1975. The 645 PRO TL is the latest masterpiece in this series and

Incorporates all the latest mechanical, electronic and optical advances. Its
external appearance, too, has been modernized and its ergonomic design

further enhanced.

We are

sure

that you will enjoy the many advantages this camera and its
accessories offer and want to particularly mention :
The 645 PRO TL has a built-in self-timer (delayed shutter release) which will
also facilitate time exposures. Attaching special leaf shutter lenses will
automatically set the focal plane shutter to 1/8 sec. Heavy duty gears connect
to the improved Power Drive Grip

WG401,

This grip also automatically cocks
the leaf shutter lenses and permits remote control.
The AE Prism Finder

FE401,

specially created for this camera, automates

exposure and shows LED safety signals. 35mm film holders now

come

with

panoramic adapters. A super fast 300mm

f/2.8

APO lens was also designed
for this camera.
We are

convinced

that your camera will serve you well, because we have

designed it for

heavy

professional use. However, we ask you to please read all
operating instructions carefully before you put your equipment to work, in
order to ensure proper operation and maximum results

This manual covers the basic
camera.

Separate instructions
are supplied with all system
accessories,

including lenses,

finders, film holders, etc.

For additional information

please feel

free to contact your
authorized Mamiya dealer or

Special Features of the Mamiya 645 PRO TL

1.

Image Area about 3X larger than 35mm

Format

3.

Interchangeable Rollfilm Holder System

-

Bigger is better --

The

6X4.5cm

image size is about

3x larger than 35mm

and therefore produces far superior results. It is large
enough to be viewed without magnifier and its aspect

ratio of about 1.25 (long side :

short

side)

matches

the
standard 8 x 10 inch “ideal format”, the most popular in
photography and industrial use. It requires minimum
cropping and gives maximum film utilization. (15 or 30
exposures on 120 or 220 film respectively)

-120, 220, 35mm,

35mm

Panoramic and

Polaroid --

Permits quick film change, even in mid-roll. Many fail
safe features prevent accidental exposures or film waste.

2.

Rugged, Versatile and Reliable Camera

Body

-

Built for professional

use

--

Mamiya pioneered the 645 SLR camera system in 1975
to create medium format image quality with 35mm

handling ease. New models have periodically followed
over the years to keep in step with mechanical, optical
and electronic advances

4

.

Interchangeable Viewfinders

1. AE Prism Finder FE401

The AE (automatic exposure) Prism Finder FE401
features three modes of TTL metering, including
automatic switching from center-weighted averaging
to spot metering. It also has a

+3EV

exposure

compensation adjustment.

2. AE Finder FK402

Light weight, Keplerian (non prism) AE aperture
priority finder offers an unreversed, upright image

Features telescoping eyepiece with diopter

adjustment from

+5

to -5.

3. Prism Finder

PF401

The Prism Finder

PF401

is without metering

electronics and designed for manual photography

mode. Both Prism Finders show an unreversed,
upright image and are ideal for eyelevel photography.

4. Waist Level Finder N

The Waist level Finder N is desirable for low angle
photograhpy and particularly for horizontal
composition.

A self erecting hood with built-in magnifier shields
groundglass from all ambient light. A built-in
sportsfinder permits eyelevel viewing and is ideal for
action photography.

5.

Interchangeable Focusing Screens

The camera

comes

with a Type E, bright, split image,
micro prism screen, useful for most applications. Five
other types, for all specialized requirements, are also
available.

6.

Large Selection of World-Class Mamiya

Lenses

Mamiya’s in-house optical engineering and
manufacturing department produces lenses specially
designed for the medium format, of unsurpassable
resolution, contrast and

color

fidelity. From

24mm Fisheye

to 500mm telephoto, plus macro,

zoom

and APO lenses,

these lenses have become the choice of the pros.

7

. Motorized Power Drive Grips

Two accessory motorized drives, interchangeable with
the manual film advance crank, are incorporated into an
ergonomically designed grips for easy, right handed
camera operation.

Model WG 401 requires 6 AA batteries and features
multiple exposure switch, cable release socket, battery
check and continuous shooting. It also can be used with
leaf shutter

lenses.

Model WG402, a simplified version, permits only
individual exposures, uses one 6 Volt lithium battery and
is much lighter.

8.

A Broad Accessory System

For Specialized Applications

A useful accessory system to serve the specialized
needs of the photographer. It includes Auto Bellows and
Auto Extension Rings for close-up and copying work;
Infrared Remote Control for studio and nature
photography; External Battery Case for operating in cold
surroundings; Camera Grips for convenient holding and
more.

<Self-timer>

Self-timer for delayed shutter release. When activated it
will light a red pilot lamp in the front of the camera for
eight seconds and will blink for two seconds before
triggering the shutter.

<Time

Exposure>

Time exposures are made by utilizing the Self-timer and
the

"B"

shutter setting. A new power saving circuit

design switches the battery off and extends is life.

9

TTL (through-the-lens) Flash Exposure

. Automation

The light that hits the film surface during exposure is

reflected to a photoreceptor within the camera body

which automatically adjusts the flash output to the

required level.

10

.

Other Features

<Mirror Lock-up>

After focusing, the mirror can be locked up before
making an exposure. This is convenient when the
camera is used at slow shutter speeds and is mounted
on a tripod for telephotography, copywork, etc.,
since even a very small amount of vibration should
be eliminated.

<Self-timer>

Shutter will be released 10 seconds after shutter
button is pressed.

<Time Exposure>

When making time exposures, the battery circuit is
automatically disconnected, to save battery power.
This is especially useful for

astrophotography.

The Memo Clip on the back of the

also be used for other reminders.

Each film holder has this important
feature. It electronically interfaces the
film holder with the AE Prism Finder,
the focal plane shutter and the lens
diaphragm, for exposure automation.
This eliminates the need of having to
manually reset the meter, every time
you change film holders loaded with
different films. Therefore make it a
routine to always set this dial with the
speed of the loaded film.

Focusing with the Standard Focusing Screen N Type E

r-

1.

The camera comes equipped with
a bright, Type E, Rangefinder/Micro­prism Focusing Screen. It features a
center, split-image rangefinder spot
and the subject is in sharp focus
when the split

images combine into

one.

2. The microprism ring around the

split-image center further facilitates

focusing. The microprisms disappear

only when the subject is in sharp

focus.

3. The rest of the ground glass area
can also be used for focusing.

*Interchangeable Focusing

Screens
There are five additional focusing
screens available for specialized
applications. They are easy to
interchange and come with in­structions.

Depth of Field

Reading the Depth of Field Scale

Depth of field is defined as the

zone

of sharpness before and behind the

plane of focus. It depends on camera
subject/distance, focal length of lens,
aperture setting and distance the lens

is focused at.

~11

16 22

1

I

In

addition

to visual observation, the
Depth of Field can be determined by
using the Depth of Field Scale on
each lens. f/stop numbers

appear on
both the right and left side of the red
index mark in the center of the scale
ring. Simply read the figures which
appear above the f/stop numbers on
the distance scale of the lens.

For example, with the 80mm

f/2.8N

lens focused at 3m and the aperture

set at f/22, the depth of field scale

indicates that the zone of sharp

focus

will extend from about 2m to

6m.

This is an important feature when the
tripod mounted camera is used at

slow or long exposure times and
particularly also with use of long

Flash Photography

In addition to its standard flash sync system, the Mamiya
645 PRO TL features TTL (through the lens), off the film

(OTF),

electronic flash exposure automation. A flash

sensor located inside the camera body reads the flash

reflected from the film surface at the moment of exposure.
The .sensw is connected via coilcords to a dedicated
electronic Metz SCA 396 thyristor module, which is
attached to the flash shoe of the camera. The module has
an

IS0

dial on which the speed of the film in use is set. The

resulting flash exposure automation determines correct
flash exposure and automatically adjusts the output of the
flash. It also automatically corrects for exposure
compensation ordinarily required when using filters, close-

up bellows or extension tubes. However, as all TTL

systems, it requires manual compensation

for differences

in film surface reflection characteristics. Compensation is

made by adjusting the film speed selector setting an SCA
396 module. The amount of compensation is determined

by experimentation.

Important:

Read Operating Instructions which are supplied with
flash unit before use.
Always turn off camera’s

power

switch when attaching

or

removing flash units.

TTL Flash Photography with

Metz

Flash Units

1. Attach a Metz flash unit which

features TTL function to the camera.

Attach the SCA396 module to the
camera’s flash shoe. Connect the
module’s coiled cables to the camera
and the flash unit.
Set the film speed dial on the SCA396
module to the

IS0

rating for the film

in use. The range of

IS0

is 25 to

1250.

2. Move the flash unit’s power switch
to ON and the mode selector to TTL.

3. Turn the camera’s shutter release
selector switch to ON. When the
charge cycle is completed you will
see an illuminated green

5

readylight

in the middle of the right side of the

0

finder. When the SCA396 module is
connected, the camera’s focal plane
shutter will automatically set at

1/60

sec,

and ignore the settings on the

shutter speed dial between

1/60

to

1/1000, including A and AEL. Slower

shutter speed settings, however,

(1/30

to 4 sec.) are not affected and

will allow flash synchronization.

4. Set lens to the desired f/stop and
shoot. After the exposure is made,
the illuminated green

f

blinks,
confirming proper flash exposure. If
the illuminated green f does not blink
after exposure, it is possible that

aperture selected is not within the
exposure/distance range of the flash.
In this case, select a wider aperture
setting. When using flash at
maximum distance, which requires

the full power of theflash

unit, recyling
time will be longer. Wait for the
readylight to go on before firing the
next frame. Exposure Compensation
with TTL Flash Automation.

Because TTL Flash automation reads
the light reflecting off the subject,
exposure may require manual

adjusment in cases where subject

and background are predominantly
white or black (e.g. bride in white

dress against white background;

bridegroom in tuxedo against dark

background.) In these instances, the

resulting

TrL

exposure will either be

under-exposed or over-exposed. For

such situations, adjustment of about

1 to 1

l/2

f/stops, plus or minus, may

be

requiredthroughexperimentation.

Alternatively, a hand held incident
flash meter reading will show proper

exposure in these cases.

Things to Watch

*

When using the AE Prism Finder FE401

When using this finder it is imperative that the Film

Speed Dial on the Roll Film Holder is properly set for

the

IS0

number of the loaded film, as it interfaces with

this finder. If not done, wrong exposures may result.

* When the mirror is locked in the up position.

The Focal Plane Shutter Curtain may be damaged if

the camera faces strong light sources, especially the
sun. Return mirror to normal position or use lens cap
to prevent such damage.

with the camera by the factory
may have been subject to storage conditions which
have reduced its service

life. Check

it before use and
always carry spare batteries.
Be sure to wipe battery contacts before inserting it, in
order to insure proper contact.
Be sure to observe proper polarity. (Match +pole of
battery with

Special Advice To Professional Photographers

Your Mamiya 645 PRO TL is designed for heavy
professional use and will give you a long

service

life if
properly maintained. Your camera and lenses have
many moving parts which require periodic lubrication. Its
electronic components, too, are subject to wear and tear
and are affected by ambient conditions like dust, sand,
sea air, heat and moisture.

If cameras had odometers like automobiles. it would be
easier to specify servicing schedules. May we suggest

that if you shoot thousands of film rolls

per

year, you send

your equipment annually for servicing by the Mamiya

distributor in your country
