Mamiya 645 AF User manual

Congratulations on your purchase of the Mamiya 645 AF Camera.
Mamiya pioneered the 645 SLR system camera three decades ago and the
Mamiya 645 AF, with its TTL auto-focus, auto-exposure, auto-flash and auto-
film winding features, is the latest Mamiya master piece and reflects its long
tradition of medium format camera expertise.
Combining 35mm handling ease and speed with the advantages of an
almost 3x larger image size, it is a full-featured camera, utilizing many digital
controls, LCD displays and is ready for the age of digital photography.
Its high-tech focal plane shutter with speeds to 1/4000 sec. permits sync
flash up to 1/125 sec. and has an exclusive "Safety Retraction" feature,
which protects it against accidental damage.
The AE Prism Finder with its many features, protected by a sturdy
magnesium housing, and also the Power Drive Grip, are now integral
components of the diecast aluminum camera body, designed for heavy
professional use.
All the many features, safety interlocks and other important information are
covered in detail in these instructions. It is imperative that you read them
thoroughly before you put your camera to work, in order to ensure proper
operation and maximum results.
Note:
In order to acquaint yourself with the functions of the camera, you will want to
practice without film. Please see bottom of page 37 how the camera can be tested
without film.

Special Advice To Professional Photographers
Your Mamiya 645 AF 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.

Inserting the Batteries (The camera will not operate
without batteries)
Set the shutter release mode selector lever to "L" (to turn the power off).
Use six "AA" alkaline and lithium batteries.
1. Lift the battery case lock lever, turn it counter
clockwise and pull out the battery holder.
2. Insert fresh batteries with the + and
-
ends as
shown in the drawing.
• Be sure the batteries are placed with
proper polarity
3. Return the battery holder to its case and lock
it by turning the lever clockwise. Make sure it is
firmly attached.
*After inserting the batteries, set the date and time. (See page 73.)
Checking the Battery Power
Set the shutter release mode selector lever to "S" (to turn the power on).
Check the battery condition in the lower right corner of the main LCD.
The batteries are sufficiently charged.
There is little power remaining. Have new batteries
on hand.
Camera will still operate.
There is very little power remaining. Camera will
not operate.
*Set the shutter release mode selector lever to
"L" (to turn the power off) and replace the
batteries with new ones.
*When the batteries are spent, "batt" flashes
on the main LCD and the viewfinder's LCD
when the shutter release button is pressed.
• When replacing the batteries, be sure to use six new batteries of the same
type. Do not mix different types of batteries or old batteries with new ones.
Amount of film that can be taken with one set of batteries
At normal temperature (20°C), using new batteries, 120 roll film and under normal
usage. Alkaline batteries : 150 rolls
Lithium batteries : 300 rolls

Diopter Adjustment
Look through the viewfinder and make sure that the focus frame (Rectangle with Circle)
is in sharp focus. If it is not, turn the diopter adjustment dial in the "-" direction if you are
nearsighted, in the "+" direction if you are farsighted. If this is not sufficient you may
require an optional diopter corrected lens. See below.
*Point the camera at a bright, plain object such as a white wall when making
this adjustment.
Range of adjustment of diopter corrected
lenses (Optional accessory)
Replacing the diopter corrected lens
1. Remove the lens supplied with the finder by
pulling it downward.
2. Push the replacement diopter corrected lens
upward into the viewfinder's eyepiece frame
until it clicks into place.
*If there is dirt or dust on the lens surface, remove it with a blower or sweep it off
gently with a lens brush.
*If there are fingerprints or dirt on the lens surface, wipe it off with a piece of clean,
soft gauze.
*Using solvents could discolor the diopter corrected lens frame.

Attaching/Removing the Lens
Attaching
1. Remove the camera's lens opening
cap, just like you would remove a
lens, by pushing the lens release
button “A” backward and then turn
the lens cap or the lens itself
counter clockwise and lift out.
To remove the front lens cap, squeeze the shiny
sections together and lift out.
To remove rear lens cap turn it counter clockwise.
2. Attaching the lens
Align the red alignment dot of the lens (on the
shiny flange) with the camera's red dot, fit the
lens into the camera and rotate it clockwise until
it clicks into place.
*Do not touch the distance ring or other
rotating parts during the auto focus
operation.
Removing
While pushing the lens release button “A”, rotate
the lens counter clockwise until it stops and lift it
off.
*After removing the lens from the camera body, protect both ends by attaching
the caps.
*Oil, dust, fingerprints or water on the electronic contacts could result in
malfuncti
on or corrosion. Wipe such impurities off with a clean piece of cloth.

Installing the Battery in the Magazine
The button battery supplies power to the magazine's LCD when it is detached from the
camera. When it is attached the power is supplied by the camera's batteries.
1. Remove the battery compartment
cover screw.
Use a coin or suitable screw driver and turn it
counter clockwise.
2. Insert a battery.
Insert the battery according to the polarity
indication + in the battery compartment, and
close the battery cover.
Battery used: Sony CR2032 or equivalent
•Be sure to watch correct polarity
*When the battery is exhausted, remove it immediately and replace with a new
battery. Otherwise accidental battery fluid leakage may damage the contacts.
Setting the Film Speed
The film speed (ISO sensitivity value) is the reference for all exposure and must be set
correctly. If the set value differs from the actual value of the film in use, under- or
overexposure may occur.
1. Press the ▲(up) button.
When the LCD panel displays information, press
and hold the ▲(up) button on the bottom part of
the LCD for more than 1 second. The ISO
indicator will blink.
2. Set the film speed.
Set the film speed of the film by pressing the▲
(up) or ▼ (down) button. To lock the speed
setting, press and hold the two buttons
simultaneously for more than one second; the
film speed will be written in memory in 5 seconds.
*The setting is not complete while the ISO indicator is blinking.
*The information on the film in use, such as the type, ISO sensitivity value and
number of exposures, is stored in the back -up memory. However, when the
battery capacity has dropped during stand-alone use of the magazine, the
information may not be shown by the LCD panel.
*The information on the film (type, ISO sensitivity and number of exposures) is
stored in the memory, but when the battery power is low this information may be
displayed erroneously. Be sure to replace the batteries with new ones.
