We know that when you purchase an exciting new product like your
Mamiya/Sekor Auto XTL Camera, you want to use it immediately. For this
reason, here is an AUTO XTL SHORT COURSE to show you how to take a few pictures before you read the detailed instructions on all the great
features at your command. Have fun.
SHORT COURSE OF INSTRUCTIONS
INSERTING THE BATTERY
|Your new Auto XTL Camera is supplied with a silver oxide battery (S76) especially designed for its unique metering system. It will last approximately one
year depending upon use and must only be replaced with an Eveready S-76 battery or equivalent. No other substitute can be used.4www.butkus.org
Open the battery compartment on the base of the Auto XTL by turning the cover counter-clockwise with your thumb and fore finger, and remove (A). You may use a coin to loosen the cover if it is too tight, but continue to remove it with your thumb or forefinger..
Clean the battery contacts with a clean dry cloth to assure they are free of oil or dust which can interfere with making positive contact. With the (+) sign facing you (B) insert the battery and replace the cover, tightening with thumb and forefinger, turning it clockwise until It's tight.
When the camera is not in use, or when changing lenses, always LOCK the meter in the OFF position. To do this, press the button on top of the film advance lever (C).
CHECKING POWER SUPPLY
Press the red Battery Check Button located near the Rewind Knob. A green light will show in the small circular window to the right of the Rewind Knob indicating the battery has sufficient power (D).
Check periodically in this manner to make sure that the battery is up to operating power.
LOADING THE FILM
Pull up on the Rewind Knob until lock disengages and film door swings open (E). When you do this the Exposure Counter will automatically return to zero.
Drop the film cartridge into the chamber, push down and rotate the Rewind Knob until it drops into its fully seated position.
Rotate the take-up spool with your finger until one of the slots is facing you. (The arrow on the take-up spool indicates the direction in which it rotates). Unwind enough film (about 2 inches) so that the leading edge may be inserted in the slot (F).
With slow steady pressure advance the film with the Advance Lever and check to see that the film sprocket holes are engaged in the teeth of the film
transport sprocket (G). Close the door firmly until you hear a click. The letter " S " will automatically appear in the Exposure Counter Window every time
fresh film is loaded in the camera. Gently turn the Rewind Knob clockwise to take up the slack of the film.
Press the Shutter Button and advance the film by rotating the Film Advance Lever to the right with your thumb until it stops. Release the lever and repeat several times until the figure " 1 " appears in the Exposure Counter Window (H). As film is advanced, the Rewind Knob will rotate in a counter-clockwise direction indicating that the film is advancing properly.
Your new Mamiya/Sekor Auto XTL camera is now ready for action.
FILM ADVANCE LEVER
SETTING THE FILM SPEED
Lift the outer ring of the Shutter Speed Dial and rotate it in either direction until the ASA number of the film you are using appears in the window (J). The
speed of the film you are using can be found in the data sheet which is packed with the film or printed on the film cassette itself.
SELECTING THE SHUTTER SPEED
The length of time that light is allowed to strike the film controlled by 'he focal plane shutter. The shutter consists of two opaque " curtains " which travel
across the opening and allow light to reach the film. The speed at which these blinds travel and the gap between the two blinds determines in fractions of
a second the exposure time for your picture. For example, 1000 on the dial indicates 1/1000 of a second and 60 indicates 1/60 of a second. The figure 1
indicates one full second. The B setting is used for longer time exposures. At this setting, the shutter will remain open as long as the shutter button is
held down. For exposures less than 1/60 of a second, it is advisable to use a cable release, tripod or other steadying devices to avoid camera movement
which can result in blurred or fuzzy pictures.
IMPORTANT: When selecting a shutter speed, do not pull up on the Shutter Speed Dial or you may inadvertently change the ASA speed setting.
SETTING THE LENS
|Now that you have determined the time the light will be allowed to strike the film, you may set the precise amount of light. This amount of light is represented by " f " numbers or f/stops engraved on the lens aperture ring which clicks into place as you rotate it. The f/stop designations indicate the opening formed by the diaphragm of your lens. When operating manually, you may use the " click stops " provided or set your lens at any setting between click stops (L).4www.butkus.org|
FOCUSING AND VIEWING
The Mamiya/Sekor Auto XTL is a single lens reflex camera. This means that you view the subject through the taking lens. Since the same image is
transmitted to the eye as to the film, parallax is eliminated. You see the picture in the viewfinder
exactly how it will appear later on your developed prints
When using infra-red film, first focus the image as above. Then note the distance as represented by the number which appears opposite the footage index mark on the lens barrel. Rotate the focusing ring until this number is opposite the small red mark, and the lens will be correctly focused for infra-red photography at that distance. This is necessary because infra-red film is sensitive only to infra-red light rays, which focus on a plane slightly behind that of ordinary light rays.
USING AUTOMATIC PHOTOGRAPHY
Your Mamiya/Sekor Auto XTL has a precision dual metering system which frees you from the necessary manual operations of conventional cameras. Now you can enjoy complete freedom and expression without
having to figure out exposure set tinge. With accurate electronic precision, the Auto XTL makes the necessary adjustments for correctly exposed
pictures. Just follow these simple steps for automatic operation:
6. Compose and focus your subject in viewfinder and take picture.
SELECTING METER SYSTEM
There are two ways of determining correct exposure with your camera. Whether you use the Spot or the Average system will depend upon the type of
picture you are taking.
SETTING EXPOSURE HOLD CONTROL
You will encounter some picture taking situations in which you may want to depart from routine metering in the automatic position such as:
Take a close up reading of the important portion of the picture, press the Exposure Hold Switch and then compose as desired. The Auto XTL metering system will " memorize " the exposure until you fire the shutter. If you are taking a portrait in an extremely back lighted situation, you can move up close to your subject and take a spot reading on a portion of your subject's face; press the exposure hold switch, and then move back to your original position. After you have taken the picture the exposure hold switch will automatically return to its original position so that subsequent photographs will not be affected by the previous " memorized " meter reading.
You can release the exposure hold switch any time by pushing up on it with your fingertip. With a small amount of pressure the exposure hold switch will return to its original position. (In situations where special readings will be repeated, we recommend that you reset the aperture ring on the lens to the f/stop which corresponds with that particular exposure setting. This procedure will ensure that all of your subsequent photographs are made at the special exposure you have selected).
USING SELF TIMER
The self timer provides a method of taking delayed action pictures, allowing a photographer to get in to his own pictures!
SELECTING DEPTH OF FIELD
When a camera lens is focused to give a sharp image of a particular subject, some objects slightly behind, as well as some objects slightly ahead of the
subject will appear to be sharp. The distance between the nearest and farthest objects, which are in focus, is called Depth of Field.
|The depth of field will appear in the finder exactly as it will be in the finished picture. By changing the focus while the lens diaphragm is stopped down,
you can select the area of sharpness in your picture. When using non-automatic or preset lenses, the diaphragm must be closed manually, but the same
results can be achieved.
You may also determine depth of field by checking the scale on the lens barrel. Numbers representing lens apertures appear at the near and far limits of depth for any given focus distance and lens opening (T).
For Example, if the standard lens is focused at 15 ft., one of the lines representing f/11 appears at the 10 ft. mark. The other line (again representing f/11) is at the 30 ft. mark. This means that a picture taken with the lens focused at 15 ft., and the diaphragm set at f/11, all objects in the picture between 10 ft. and 30 ft. will be in focus. This method is extremely valuable when the lens diaphragm is stopped down too far to allow enough light for the picture to be viewed through the viewfinder..
A variety of interchangeable lenses are available to increase your enjoyment of your new
Mamiya/Sekor Auto XTL Camera. With the wide angle and
telephoto lenses you can take pictures expressing different points of view. Telephoto lenses change the perspective normally associated with shorter
focal length lenses. For example, a telephoto lens allows you to move up closer to your subject without physically changing your position. Wide angle
lenses allow greater coverage than is possible with your normal lens. Interiors and exteriors of buildings or pictures of large groups of people are
IMPORTANT: Protect your camera body and lens from damage or dust by using a body cap for the camera body and front and rear lens caps.
<<<< Additional information not in the
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.

|The flash terminals, marked FP and X allows a choice of flash synchronizations (V). The selection of a terminal depends upon the type of flash used, as well as shutter speed. The following table shows the correct combinations to be used in various flash situations. These combinations must be rigidly followed to ensure correct synchronization.|
Shaded areas indicate the shutter speeds at which listed bulbs are to be used, with the cord attached to the indicated terminal.
REWINDING THE FILM
When you have finished taking all your pictures, (either 20 or 36 exposures), you must rewind the film back into its cartridge.
AVOID DIRECT LIGHT WHEN UNLOADING THE CAMERA.
OBTAINING MULTIPLE OR DOUBLE EXPOSURES
Your new Mamiya/Sekor Auto XTL Camera is protected from accidental double exposure under normal picture taking situations since you cannot take a picture until you advance the film and recock the shutter. However, to make double exposures for special effects:
1. Take your first picture in the usual manner.
2. Press the film rewind button on the base of the camera and slowly turn the film rewind knob clockwise until you hear a click. Stop. The click means that you have rewound the film one full frame. Next, advance the film twice. This cocks the shutter and repositions the original frame for the second shot or double exposure.
Manual or Stopped-down Aperture Operation with Lenses and Accessories
You can use lenses other than Auto Mamiya/Sekor ES lenses with accessory
Mamiya/Sekor " P " and " T " adapters such as:
Here's how the above lenses are used:
1. Mamiya/Sekor or Praktica mount automatic lenses.
(a) Attach Mamiya/Sekor " P " adapter to your Auto XTL camera by matching the red dots and turning clockwise until it clicks into position.
(b) Mount lens by screwing it into the adapter.
(c) Turn meter on and focus.
(d) Depress Depth of Field preview button and rotate aperture ring until meter needle in viewfinder moves into index mark O (see viewfinder control center diagram) immediately above the f/1.4 index.
(e) Release the Depth of Field preview button and shoot. The lens will now automatically stop down to the proper exposure setting (Y).
2. Preset "T" Lenses
(a) Attach Mamiya/Sekor " T " adapter to any preset " T " lens by screwing on to the lens until it is fully seated.
(b) Mount lens and adapter combination to camera by matching the red dots and turning clockwise until the lens clicks into place.
(c) Focus on the subject.
(d) Rotate aperture ring until meter needle in viewfinder moves into index mark O immediately above f/1.4 index mark. (See diagram) (Z).
You can use your new Auto XTL Camera on microscopes, extension bellows, slide copiers, extension rings, and copy stands. Use these accessories
by following the " stop down " method of manual exposure meter reading outlined above. Please refer to instructions enclosed with the accessories.
Problem: FILM COMPLETELY BLANK WHEN PROCESSED, INDICATING NO EXPOSURE HAS BEEN MADE.
Possible cause: Improper loading. Review the section on film loading and be sure you are loading the camera correctly, with the film being securely attached to the take-up spool and winding in the CORRECT DIRECTION, that is, UNDER the take-up spool. Film may not have gone through camera at all.
Problem: SELF TIMER DOES NOT OPERATE SHUTTER.
Possible cause: Timer not rotated full 30 degrees. Timer must be rotated to some point between 30 and 70 degrees.
Problem: FLASH PICTURES EITHER BLANK OR ONLY PARTIALLY EXPOSED.
Possible cause: Improper shutter speed for the type of bulb used.
Or improper cord receptacle used for the type of bulb or shutter speed. Check Flash Synchronization tables carefully.
Problem: SHUTTER WILL NOT RELEASE.
Possible cause: Film Advance lever not advanced far enough. A full stroke is necessary for cocking the shutter. However, a ratchet incorporated within the advance mechanism will allow you to accomplish a full wind in a series of short strokes.
If any problem listed above cannot be solved in the manner suggested, do not attempt to repair your camera. Take it, or send it, instead, to your nearest service station. A minor problem could possibly be aggravated by tampering.
STORAGE: If the camera will not be used for an extended length of time, store it with the shutter uncocked. This relieves tension on the spring. Lock the exposure meter " Off " and remove the battery. Never store in areas where temperatures exceed 100 degrees F. or go below freezing (32 degrees F).
Protect against excess moisture by using silica gel or other desiccant.
Never expose the camera to direct sunlight for extended periods of time. Avoid areas where exposure to salt water or salt air occurs.
CARE AND CLEANING: Use a blower or camel hair brush to clean film chamber and area around take up spool before loading film into camera. Never use your own breath to blow out dust from a camera. Your breath is full of moisture which will cause corrosion of the precise operating parts of your camera. Clean lens with lens tissue and a good quality lens cleaning liquid only. Do not clean lens at all unless you notice that it needs it. Avoid rubbing the surface of the lens if there is any loose grit or dirt present.
Don't use a handkerchief. Never touch the lens with your bare fingers. Never rub the surface of the reflex mirror. If there are foreign particles of any kind that cannot be removed by blower or camel hair brush, leave them alone until a factory approved serviceman is available. Dirt on the mirror can have no effect on the picture.

One way to use the Mamiya ZE
"P" adapter with the Mamiya ZE-X without damaging the ZE-X is to first
attach an Osawa MC-4 ZE 2x teleconverter to the ZE-X camera body. Then you can
attach the ZE "P" adapter to the teleconverter in order to use lenses
from the DSX, MSX, DTL and TL series of cameras. Of course you will have
then doubled your focal length by two but at least you have the ability to
use those M42 lenses with the ZE-X. When used with the ZE-X, the Osawa
MC-4 ZE 2x teleconverter will not allow a light meter readout in the
viewfinder from Mamiya M42 type lenses with ZE "P"
adapter or any E or EF type lenses without ZE "P" adapter.
The MC-4 ZE 2x only gives a light meter readout in the viewfinder with the
ZE-2 camera, and set apertures will have no effect as far as the light meter is
concerned in the ZE-X. A hand-held light meter will be required for the ZE-X so
you can then set the aperture and shutter speed needed in fully manual mode. A
correct exposure can then be obtained with the ZE-X/MC-4 ZE 2x combination.
The ZE "P" adapter alone, may also be used directly on Mamiya NC type
cameras with lenses for DSX, MSX, DTL and TL series of cameras. (Note: E and EF
type lenses for the ZE, ZE-2 and ZE-X are not interchangeable with CS type
lenses for the NC series of cameras and vice-versa.)
The "P" Adapter permits the use of automatic or preset lenses using the universal screw mount. In the case of lenses having an automatic diaphragm pin the "P" Adapter will allow you to use these lenses in a semi-automatic fashion. that is, using the "stop down" method of metering the Auto XTL through the "P" Adapter will activate the diaphragm pin during exposure.
Description of Parts
1. Attach the P Adapter to your Auto XTL camera by matching the red dots and turning clockwise until it clicks into position.
2. Mount lens by screwing it into the adapter.
3. Turn meter on and focus.
4. Depress the Depth of Field preview button and rotate the aperture ring or shutter speed dial until meter needle in viewfinder moves into index mark ~ immediately above the f/1.4 index.
5. Release the Depth of Field preview button and shoot. The lens will now automatically stop down to the proper exposure setting
