INSERTING BATTERIES - Batteries must be good for shutter to work.
Remove the Battery Compartment Cover (36) by rotating it a quarter turn counterclockwise with a fingertip or coin, Insert two 1.5V silver-oxide batteries (Eveready
S-76, Mallory MS--76 or equivalent) into the Battery Compartment with the + (positive) side facing the Battery Compartment Cover (it has a plus sign indicated
as a reminder on its underside). Perspiration, grease and dirt are harmful to the batteries so do not handle them by your fingertips when inserting into the battery
compartment. Batteries should be wiped with a soft, dry cloth or tissue before insertion. After inserting batteries, replace the Battery Compartment Cover, aligning its white dot with the "O" (open) symbol indicated on the
camera, and lock cover into place by rotating it a quarter-turn (90°) clockwise.
4. To assure consistent performance and the utmost accuracy, your Mamiya camera is equipped with an electronic shutter. However, when the batteries are exhausted, or there are no batteries in the Battery Compartment., the focal plane shutter will function only at B (bulb), and when the Shutter Speed Ring is set to any shutter speed other than B. a speed of approximately 1/1000 sec. will result. Of course, the metering system will not operate at this time.
Battery Check and exposure meter switch
After inserting the batteries, check their voltage by pushing the Battery Check Button (27). If the Battery Check Lamp (8) illuminates, it indicates the batteries are
in good condition. Battery condition should also be checked when the camera has not been used for a long period of time. When the Battery Check Lamp fails to
light, remove the batteries and wipe with a soft, dry cloth to assure good contact, Failure of the Battery Check Lamp to light after wiping the batteries indicates they must be replaced with fresh batteries.
Avoid direct sunlight when loading and unloading film. Pull up on the Film Rewind Knob (7) to open the Back Cover (33), and drop a 35mm film cartridge into the
film chamber (28), locking the cartridge into place by pushing down on the Film Rewind Knob. If the Film Rewind Knob does not return flush with the camera top,
rotate it while gently pushing downward until it recesses flush.
Insert the film leader into one of the slots in the Film Take-up Spool (32). The arrow appearing on the Film
Take-up Spool indicates the direction in which it
Wind the film until both the upper and lower sprockets (31) are engaged in the film perforations. If the Film Advance Lever stops advancing, free it by depressing
the Shutter Release Button (4). Before securely closing the Back Cover, take up all the slack in the film by gently rotating the Film Rewind Knob clockwise,
Move the Film Advance Lever as far as it will go and then depress the Shutter Release Button. Repeat the above procedure until the Exposure Counter indicates 1
(one). The camera is now loaded and ready to use.
Each time the film is advanced and the shutter cocked, the Exposure Counter advances one number, informing the user of the number of frames the film has
been advanced. When the Back Cover is opened, the Exposure Counter automatically returns to "S" (start).
Setting the film Speed
Before taking pictures, be sure to adjust the camera to the film speed of the film being used. To do so turn the Shutter Speed Ring (16) while depressing the Film
Speed Ring Lock Button (18) until the correct ASA or DIN number (as indicated on the film information sheet) appears in the appropriate window (14). When
setting the film speed, hold the knurled portion of the Film Speed Ring (17) with one hand and depress the Film Speed Ring Lock Button with the other hand.
The correct values of the dots appearing between the ASA and DIN numbers are indicated by the smaller numbers in the table below.4www.butkus.org
When using the automatic exposure (AK) system of your camera, be sure to set the Aperture Ring (23) of the lens to the AE position. To do so, rotate the Aperture Ring until the orange AE Button (26) is aligned with the similarly colored Central Index Mark (24). When set to the AE position, the Aperture Ring will lock into place.
Setting the Shutter Speed
The numerals on the Shutter Speed Ring indicate fractions of a second; thus, "500" represents 1/500 second. For an exposure time of longer than 1 second, the
Shutter Speed Ring is set to "B" (bulb). In this position, the shutter will remain open for as long as the Shutter Release Button is depressed.4www.butkus.org
|Lighting Condition||Shutter Speed|
|Outdoors, Sunny||1/250 or 1/125 sec.|
|Cloudy or in the shade||1/125 or 1/60 sec.|
|Twilight or interiors||1/30 sec.|
1. While looking through the viewfinder, adjust the Focusing Ring until the most important part of the subject appears sharp.
Determining of Correct Exposure
Pull the Film Advance Lever slightly away from the camera to its click-stop position and look through the viewfinder to check that the Exposure Meter Indicator
Needle is located within the correct exposure area before releasing the shutter.
· Correct Exposure Area
The correct exposure area is anywhere between the upper edge of the numeral corresponding with the maximum aperture and the lower edge of the numeral of the minimum aperture of the lens being used.
For example, when using an f/1.4 lens and the Indicator Needle points anywhere between the upper edge of 1.4 and lower edge of 16 on the aperture scale in the viewfinder, correct exposure will be obtained.
When using an f/1.7, f/2, or f/2.8 lens, the upper edge of the respective numeral on the aperture scale in the viewfinder is the upper limit of the correct exposure. When using an f/3.5 lens, the lower edge of 2.8 is the upper limit of the correct exposure.
If the Indicator Needle moves beyond the upper limit, underexposure will result, so adjust the Shutter Speed Ring to a slower shutter speed until the Indicator Needle drops into the correct exposure area.
If the Indicator Needle lies below the lower limit, this indicates overexposure, and the Shutter Speed Ring should be adjusted to a faster shutter speed until the Indicator Needle enters into the correct exposure area.
The Aperture Scale is found on the left-hand side of the focusing screen area. The Exposure Meter Indicator Needle moves up and down in this area, indicating the aperture automatically selected by the camera when the Aperture Ring of the lens is set to the AE position.
Stop-Down Metering Index:
This index is the small rectangular area found beside 1.2 on the Aperture Scale. For manual stop-down metering, the Indicator Needle is aligned with this index. Details appear later in this text.4www.butkus.org
Holding the Camera Correctly
Support the camera in the palm of the left hand with the thumb and forefinger gripping the Focusing Ring. The palm of the right hand should fit against the right side of the camera body with the forefinger resting near the Shutter Release Button and the thumb on the camera back.
Look through the viewfinder with the camera resting against the forehead to help steady it and the left elbow held in against the body.
* During automatic exposure (AK) operation, be careful not to inadvertently apply pressure to the Meter OFF Button while releasing the shutter, otherwise incorrect exposure may result.
* When attaching the camera to a tripod that has a long attachment Drew. adjust the Drew to less than 3/16 inch (4.5mm) to prevent damage to the interior of the camera body.
After exposing a roll of film, it must be rewound into its cartridge, for if the Back Cover of the camera were to be opened without first rewinding, anywhere from a
few frames to the entire roll may be ruined.
Using the Self-Timer
The Self-Timer provides a method of taking delayed action pictures, allowing a photographer to get into his own
When using the self-timer in the automatic exposure (AK) mode, be sure to attach the Hot Shoe Safety Cover (5A) (which also doubles as a viewfinder cover) to the Viewfinder Eyepiece (29) to prevent extraneous light from entering the eyepiece, possibly causing underexposure.
When using the self-timer, be sure the Film Advance Lever is at its click-stop position, protruding slightly from the camera. If the lever is flush with the camera top, the meter is turned off.
If the self-timer is started with the Film Advance Lever flush with the camera top, the shutter will not release because pushing the Meter OFF Button not only turns off the meter, but also locks the shutter release mechanism. In the event that the self-timer is accidentally started with the Film Advance Lever flush with the camera top, pull the lever out to its click-stop position and then reset the self-timer; there will be no need to push the Self-timer Activating Button again because the self-timer will start as soon as pressure is released from the Self-Timer Lever.
Your camera is provided with two flash Sync Terminals: FP for synchronization with FP class flash bulbs, and X for synchronization with electronic flash units. Compact electronic flash units designed for cordless operation may be attached to the Hot-Shoe (5) after its Safety Cover is removed. For a large flash unit used with a bracket, or for a compact electronic flash unit without provision for cordless operation, attach the flash synchronization cord to the appropriate Sync Terminal.
The shaded areas of the Flash Synchronization Chart indicate the usable shutter speeds with the various types of flash illumination. For example, when using electronic flash, the Shutter Speed Ring should be set to 1/60 sec. or slower (1/60 to 1 sec., B).
· Exposure for Flash Photograph
In flash photography, exposure is determined by the guide number of the flashbulb or electronic flash unit. The guide number represents a relationship between the power of the flash and the speed of the film. Flashbulb guide numbers can be found on their package. Guide numbers for electronic flash units are found in the manufacturers specifications. Once you've found the correct shutter speed for your type of flash, (see Flash Synchronization Chart), you can compute the correct lens opening by this formula.
GUIDE NUMBER / CAMERA-TO-SUBJECT DISTANCE = APERTURE
If the flash you are using has a guide number of 56, for example, and if, after focusing, you determine from the lens barrel Distance Scale that the subject is 7 feet away, divide 56 by 7. The answer is 8, therefore the correct aperture is f/8 (56 / 7 = 8 [f/8] ).
Not only is flash the most effective light source for indoor photography end for shooting in dimly-lit places, but it's also an effective tool for backlighting outdoor portraits and filling in shadows outdoors. Remember that when flash is used as a supplemental light source, exposure must be based on the light from the main light source (such as the sun). Remember, also when shooting with electronic flash, the Shutter Speed Ring must be set to 1/60 sec. or slower (1/60 - 1 sec., B).
To remove the lens from your camera, push in on the Lens Release Button (12), securely grip the lens by the lens barrel, give it a short (approximately 45°) twist
counterclockwise, and after the lens stops, merely lift it straight out of the bayonet mount.
Outline of "AE" (Automatic Exposure) Operation
Mamiya NC P adapter instructions
The procedure appearing below in sketch form is designed for future use to serve as a quick review of the operation procedure which is explained in detail on the following pages. It is also designed for immediate reference by those already well acquainted with sophisticated 35mm SLR's.4www.butkus.org
In order to meet almost every photographic need, the Mamiya NC 1000S includes a variety of features. Mastery of these features will not only lead to better pictures, but will open up the doors to new photographic possibilities as well.
Depth of Field
When the camera is focused on an object, an area in front of and behind the object will also be in acceptably sharp
To preview the depth-of-field push in on the AE Button (26) and rotate the Aperture Ring (23) until the same F number indicated by the Exposure Meter Indicator Needle is aligned with the Central Index Mark (24).
Next, push the Depth-of-Field Preview Button (13) as far as possible and the diaphragm of the lens will stop down to the previously selected aperture, making it possible to preview the depth-of-field. Releasing your finger from the Depth-of-Field Preview Button will return the diaphragm to its maximum aperture. After this is done, you can take a picture, However, it is better to return the Aperture Ring to the AE position immediately after previewing the depth-of-field to minimize the possibility of future error.
If the focusing screen is not sufficiently bright, because of a dark subject or small aperture, to clearly distinguish the depth-of-field, you can determine the approximate depth-of-field by referring to the Depth-of-Field Scale (24) on the lens barrel.
For example, if the standard (50mm) lens is focused at 15 feet, one of the marks representing f/11 appears at the 10 foot mark and the other at the 30 foot mark. This means that in a photograph focused at 15 feet with the diaphragm set at f/11, everything between 10 and 30 feet will be in acceptably sharp focus.
The automatic exposure system can be disengaged at any time by pushing the AE Button to unlock the Aperture Ring and rotating it to the desired aperture. Even when in the manual mode, the Exposure Meter Indicator Needle continues to indicate correct exposure so that it may be used as a reference point to assist the photographer who deliberately wishes to over or underexpose for special effects. For example, when the Indicator Needle indicates f/8, the photographer can overexpose two stops by manually setting the Aperture Ring to f/4; similarly, he can underexpose two stops by setting the Aperture Ring to f/16 instead of f/8.
Correct Exposure in Unusual Lighting
Your Mamiya camera automatically computes correct exposure in most photographic situations. However, in unusual circumstances such as when the background area is large and much brighter or darker than the subject, it is best to make an exposure adjustment to lighten or darken the principal area of interest.
When the background is exceptionally bright, as when the subject is strongly back-lit, underexposure of the subject will normally occur and this will render the subject excessively dark. To prevent this from happening, tilt the camera so that the bright background or bright light source is not included in the viewfinder and then press the Shutter Release Button slightly (about 1mm) to lock the exposure in place. After the Indicator Needle locks, recompose the image in the viewfinder while maintaining pressure on the Shutter Release Button. Then, apply additional pressure to the Shutter Release Button to trip the shutter and take the picture.
When you desire to have a brightly back-lit subject appear as a silhouette, do not make the exposure correction suggested above, but simply compose and shoot.
· AE Correction for a Dark Background
When the background is very dark in relation to the subject, as when photographing a stage performer standing in a spotlight against a dark curtain, overexposure will normally occur, washing out (overexposing) the subject. To correct for this type of situation, move very close to the subject, excluding the dark background from the viewfinder, and lack the exposure into place by slightly depressing the shutter release button, While maintaining pressure on the shutter release button to "hold" the correct exposure, back away from the subject, recompose, and shoot.
If it is not possible to approach the subject, take an exposure measurement from a similarly lighted subject (such as one's own hand), lock the exposure, recompose, and shoot.
Using Infrared Film
When using black and white infrared film it is necessary to make a focusing adjustment in order to achieve accurate focus. This focusing adjustment is
particularly important when: a) using non-wide-angle lenses b) taking close-ups c) shooting at wide apertures
Stop Down Metering
When an Auto Mamiya-Sekor CS lens is attached to the camera, stop-down metering is not possible. However, stop-down metering is used on the following
1. Focus on the subject and, while pushing the Depth-of-Field Preview Button (13) as far as possible rotate the Aperture Ring
until the Indicator Needle comes to
rest at the Stop-Down Metering Index Mark (found beside 1.2 on the Aperture Scale). Correct exposure is now set and the picture is ready to be taken. (When
using preset lenses, there is no need to manipulate the Depth-of-Field Preview Button,)
2. If the Indicator Needle cannot be aligned with the Stop-Down Metering Index Mark by rotating the Aperture Ring, change to another shutter speed. If the Indicator Needle lies below the a faster shutter speed. Conversely, when the Indicator Needle lies above the index, change to a slower shutter speed. It is not necessary for the Indicator Needle to be perfectly centered in the Stop-Down Metering Index Mark, for when the Indicator Needle enters any area of the index, it indicates that the camera has been adjusted within the range of correct exposure.
3. After adjusting for correct exposure, the usual practice is to remove one's finger from the Depth-of-Field Preview Button before releasing the shutter so that composition and focus can be rechecked at the maximum aperture. However, it is perfectly acceptable to release the shutter while the Depth-of Field Preview Button is still held.
The NC 1000 camera is protected from accidental double exposures under normal picture taking situations, however, you can make multiple (double) exposures
for special effects as follows. 1. Take your first picture in the usual manner.

Interchanging Focusing Screens - NC1000s only
| · Removing the Focusing Screen
After removing the lens, gently pull the Focusing Screen Frame Latch (22) slightly forward and both the Focusing Screen Frame and screen will drop downward, making the screen easily accessible.4www.butkus.org
* When removing the screen grasp it by its central tab. Do not touch the surface of the screen as fingerprints are difficult to remove.
* When interchanging screens handle them only by their edges.
* The focusing screens are susceptible to scratches; therefore, handle them with extreme care.
* Be careful not to touch the mirror when interchanging screens.
· Replacing the Focusing Screen
To replace or insert a new screen, hold the screen by its central tab, glossy side-down and matte-side-up, and gently insert it into the lowered Focusing Screen Frame. Carefully raise the frame upward, pushing it shut until it locks into place with a click.
* Do not try to insert the screen into the Focusing Screen Frame upside-down (glossy-side-up) as it will not fit properly.
* If the screen is not correctly seated completely in the frame, it will not be possible to lock the frame shut.
* Be sure the Focusing Screen Frame is securely locked in place before attaching a lens to the camera.
A series of five high quality filters have been designed to maintain the high performance of Mamiya-Sekor CS lenses. They come in 49, 52, and 58mm sizes, and in the following types: SY48 (Y2), S056 (02), SL39 (UV), YG, SL-1 B (Skylight).
· Lens Hoods
· Diopter Correction Lenses
Many near and farsighted persons have difficulty looking through a camera viewfinder while wearing glasses, but they can not focus accurately without them. This common problem can be corrected by using a diopter correction lens that mounts easily over the viewfinder eyepiece with the separately available Adapter and Rubber Eyecup. Diopter correction lenses are available in strengths of +3, +2, +1, - 1, - 2, and -3.
To attach a correction lens merely unscrew (counterclockwise) the diopter correction lens retainer ring from the eyecup, insert the necessary correction lens, and replace the retainer ring. Then slide the eyecup on the eyepiece of the camera for easier focusing.
Before actually purchasing a Diopter Correction Lens at your Mamiya Dealer, be sure to attach it to the camera and try viewing through it to assure correct matching with your eyesight.
|The Rubber Eyecup also helps to prevent unwanted light from entering the viewfinder from the back and sides while viewing.|
|The Magnifier is a useful aid for critical focusing as required in copy work, close-up photography, and similar applications. Only the center portion of the
viewfinder image is visible through the Magnifier, and the size of the image is doubled. The Magnifier provides a diopter adjustment of +5 to--5.
|The Angle Finder is useful for low angles and copy work. The Angle Finder has click stops every 90°, but freely rotates a full 360° and has built
in diopter corrections of--4 to +4.
Furthermore, the image seen through the Angle Finder is bright, unreversed, and laterally correct for ease of operation.
· Auto Extension Tube Set
· Auto Bellows
· Slide Copier
Used with the bellows unit, the slide copying attachment is mounted in front of the lens to allow the photographer to copy slides and film strips. It has a slide stage that moves in any direction to make it easy to crop mounted slides for better composition and a removable film tray to facilitate copying long rolls of 35mm film.
· Bellows Stand
· P-Mount Adapter for Mamiya TL/SX lenses
<<<< Additional information not in
I just wanted to point out that not all Mamiya M42 lenses are safe to use with the P adapter for the Auto-XTL. If you attempt to use the SX type lenses with the Auto-XTL P adapter, the aperture sensing pin will dig into the P adapter face since it is not perfectly flush with the outer surface edge of the SX lense. Furthermore, since the entire moving surface of the aperture ring of the SX lense comes to rest against the P adapter face, it will lock down the aperture control of the lense and make it impossible to turn, therefore preventing SX lens f-stop manipulation. Mamiya M42 AUTO lenses seem to be safe choices as are M42 Yashica-Yashinon, M42 Meyer-Optik and M42 Zeiss MC Sonnar (S) lenses. Any aperture ring that rotates at the extremity of a lens should be avoided. Of course the SX lens works perfectly well with the "ZE" P adapter for Mamiya ZE series lenses which it was designed for. Lenses with Auto and Manual switches like Zeiss MC Sonnar work well with the Auto-XTL P adapter in conjunction with its Auto Aperture pin. Lenses that have no Auto Aperture and only manual control of aperture appear to work equally well like Meyer-Optik Orestor M42.

47° angle of view, 49mm filter size).
Lens Mount: Shutter: Sync Terminals: Exposure Meter: Coupling: Film Speed Range: Film Advance Lever:
Five interchangeable focusing screens are available to meet various photographic needs.
No. 1 RangafinderSpot45°/Microprism (Supplied with camera)
The standard, and highly versatile screen which offers three-way focusing for excellent focusing accuracy. A central split-image rangefinder spot has a diagonal wedge (45° ) which makes precise focusing possible with either horizontal or vertical lines. A microprism collar surrounds the rangefinder spot, serving as a useful focusing aid with any subject. The remainder of the screen is all matte and has a Fresnel lens for corner-to-corner brightness.
No. 2 Rangefinder Spot
All matte with Fresnel lens and central rangefinder spot. It helps to achieve accurate focus even with wide-angle lenses which are usually more difficult to focus because of their extreme depth-of-field. It is also suitable for general purpose photography.
No. 3 Microprism
Entirely matte with a Fresnel lens and a central microprism spot. This is the usual focusing screen for general purpose photography for those who find a rangefinder spot distracting. The microprism assures rapid and accurate focusing and the matte surface makes the entire screen suitable for focusing.
All matte with Fresnel lens. Excellent for close-up photography, checking the depth-of-field, and for use with lenses of relatively slow maximum aperture (f/3.5 or smaller). Because focusing aids such as microprisms and rangefinders become dark when used under conditions described above they may prove distracting. The No. 4 focusing screen is designed to minimize this problem,
No. 5 Cross-Hair
Clear transparent screen with Fresnel lens and a cross-hair at the central spot. This screen doesn't give you a proper meter reading. It is for use in special purpose photography, as when working with the Auto Bellows or for astrophotography. While focusing, the eye is moved to-and-fro (right-to-left), and when the image no longer moves in relation to the cross hairs, optimum focus has been achieved.
Care of the Camera
Use a blower or camel hair brush to clean the entire film compartment before loading film into the camera. Never use your breath to blow dust or dirt from the compartment as the moisture can corrode the precision working parts.
To clean the lens surface, wipe VERY GENTLY in a circular motion with a quality lens tissue. In severe cases ~ you can use a very small amount of p lens cleaning solution, again wiping in p a circular motion. NEVER RUB THE LENS TO REMOVE DIRT OR GRIT!
If the dirt will not come loose with a brush or blower, take the camera to a factory approved service technician.
Never touch the lens with your fingers or any material other than a lens tissue. Dirt on the reflex mirror will not affect your photograph.
Store your camera in its case with the lens set to infinity and protected by its lens cap. Be sure to turn off them meter when storing the camera (this will also give the added protection locking the Shutter Release Button), if the camera will not be used for an extended period of time, remove the batteries.
Never store the camera in areas where the temperature exceeds 100 degrees F or goes below freezing (32 degrees F).
Protect the camera against moisture by using a desiccant. Never expose the camera to direct sunlight for extended periods of time.
Avoid areas where prolonged exposure to salt water or briny air is possible.
