BASIC OPERATIONS The Nikomat ELW is an aperture-priority elec- tronic automatic exposure camera, and its handling is very easy. Before using this camera, read this section on "Basic Operations" care- fully and familiarize yo ur self thoroughly with the camera.
BATTERY CARE Install ing the battery Eith er a 6-volt silver-oxide or alka lin e- m anganese battery is used to power both the exposure meter and the electromagnetic shutter-speed controlling circuits.
Battery test The battery should be checked when: * A n ew battery is install e d. * A camera is about to b e used after a lon g peri o d of storage. * It is suspected that the b attery h as been depl ete d after a l o ng p er i o d of use . Pr ess the b attery check button o n the back of the camera.
BATTERY CARE-Continued Replacing the battery When the b attery check la mp d oes n ot g l ow when pr essi n g the b atte ry check button, replace t he battery with a new o n e. (1) R emove t he lens, a nd l ock t he mir ror in the up p ositio n. 14 (2) Open the b attery chamber lid.
Notes on Battery Care Pr eve nting unnecessary di sc harge To prev e nt unnecessary discharge, set th e film- advance lever and the shutter-release button lock in the off position, except when taking pictures.
MOUNTING THE LENS To mount a lens , first push the camera's meter coupling pin to the right as far as it will go. Set the lens diaphragm at f/5 .6 and insert the lens into th IY bayonet mount, making sure that the coupling pin fits into the slotted prong on the lens.
Maximum aperture scale The above adjust m e nt can be co nfirm ed by l ook- in g at the maximum a p ert ur e scale on the ring with the coupling pin. The scale h as a ra ng e of f/l.2 to f/5.6. For example, if the 50 mm F1.4 lens is mount ed on the camera, th e red index mark should fall opposite the 1.
ATTACHING & REMOVING THE NIKON AUTO WINDER AW-1 To attach the AW-1 Align the spindle of the coupling portion of the Auto Winder AW-l with the slot of the coupling portion on the bottom of the ELW, and turn the camera attaching screw of the AW-l clockwise with a coin , and tighten securely.

GENERAL STEPS OF PICTURE-TAKING Loading a film (1) To open the camera back, slide the safety lock backward and lift up the film rewind knob as far as it goes, and the hinged camera back will pop open. 20 (2) Drop a film ma gaz ine into the film chamber with the film leader pointing toward the take- up spool.
knob and turn it gently in the direction of the a rrow until you feel a slight resistance. This t a kes up any slack in the film cartridge . Then fold back the rewind crank. * Do not load the camera in bright sunlight. If no other shade is available, shade the camera from the sun with your body while loading.
GENERAL STEPS OF PICTURE-TAKING-Continued Setting the ASA film speed The ASA film-speed dial has a scale calibrated from ASA 25 to 1600 with two dots between numbers to indicate intermediate settings, such as 32 and 40.
Winding the film When advancing the film manually, keep the film- advance lever pulled out at a 30 ° clearance angle so that the red dot is visible while pictures are being taken. This turns the exposure meter on. The shutter button lock shou ld be set at its locked position .
GENERAL STEPS OF PICTURE-TAKING-Continued Blank exposure The blank exposure is to release the shutter dispos - ing of the first few inches of film which were ex - posed during loading , not to take pictures . After loading the film, make two blank exposures and the frame counter indicates "0".
Setting the aperture ring When shooting with the camera set at A(Auto), once the film speed (ASA) dial is set, the only ex- posure control you must do is set the len . s aperture. Turn the aperture ring on the lens barrel until the desired f/number is opposite the black line (aper- ture indicator) .
GEN E RAL STEPS OF PICTU RE-T AKI NG - Continued Holding the camera Steady camera holding is important since even the slightest camera shake at the moment of exposure can result in an appreciable loss of sharpness, es- pecially at slow shutter speeds .
out of focus The range surrounded by the broken line is the approx- imate frame area seen through the viewfinder, and the outer area is the actual printed picture _ in focus Prefocusing The lens can also be prefocused using the distance scale engraved in both feet and meters on the lens barrel.
GENERAL STEPS OF PICTURE-TAKING-Continued Releasing the shutter When the shutter button is released, an exposure is made on the film. It is important when snapping the shutter not to cause the camera to shake.
Rewinding and unloading film When the frame counter indicates that the last exposure has been made or when the fi lm - advance l ever can no longer be stroked *, the roll of film has been completely exposed and should be removed. Press the rewind button on the camera baseplate, and the film is ready for rewinding into the magazine.
GENERAL STEPS OF PICTURE - TAKING - Con t inu e d P hotography with Automatic Ex p osu re Co n tro l Th e f l ow chart below shows the basic pi ct ur e- taking of auto m atic ex p osure co ntr o l with the Nik o m at ELW.
You can obtain a picture of correct exposure by .... simply snapping the shutter. You can obtain a picture of correct exposure; only that the shutter speed is slow, you are advised to obtain a faster shutter speed by changing the ~ aperture or to secure the camera with a tripod or something solid.
Before you start shooting, double-check to make sure you have done the follow in g: 1) I nstalled the battery in the battery chamber correctly . 2) Checked the battery checker to see that the lamp glows with a bright orange light. 3) Returned the mirror to the origi nal viewing position.
APPLI ED OPERATIONS It is hoped "that you have understood the basic operations of the Nikkormat ELW for taking pictures with automatic exposure control in the foregoing section. This second section should be studied to expand your knowledge on applied operations of photography .
TTL EXPOSURE METER Center-weighted exposure meter The exposure meter adopts the TTL center-weight- ed light metering system. The meter reads light over the entire focusing screen, but its light sensitivity is concentrated in the center, which corresponds to the central 12mm diameter spot of the screen.
Caution : To prevent battery drain, keep both the film-advance lever and the shutter-release button in the locked position to switch off the meter whenever the camera is not in use .
TTL EXPOSURE METER-Continued Extreme-high or low light situations If the black needle remains in "A" or "B" after all possible aperture settings have been tried, then the available light is too bright or too dim to cover the meter's EV range.
• Auto exposure control at full aperture For example, with an f/1.4 lens and ASA 100 film, the ELW's automatic shutter will function down to one second with the lens set at 1.
TTL EXPOSURE METER-Continued • How to read the EV range chart The chart indicates the EV (for ASA 100) vs. shutter speed range. To determine the shutter speed range, note that the bars in section A indicate the responsive range of the ELW's photosensitive CdS element (i .

EXPOSURE CONTROL-Continued Lens aperture diaphragm The Nikomat ELW can be used with any Nikkor interchangeable lens with a Nik on F bayonet mount . Except the reflex le n s, these l enses are eq uipp ed with a pe rtur e diaphr ag ms, and g radu ate d with a stop b y stop scale from f ull apert ur e to the minimum stop number.
Stop-down exposure measurement Full-aperture exposure measurement is not possi- ble with the following lenses and accessories. either bec a use the lenses nave no auto diaphragms or because the diaphragms will not couple with the meter.
COMPENSATION OF EXPOSURE Due to special lighting conditions, or in situations of high contrast such as occur in repro-copying, it may not be desirable to take the picture as is. The amount of exposure the film re c eives is determined by a combination of the lens aperture and the shutter speed.
How to Use Memory Lock First plac e the subject in the central part of the viewfinder, or better still, if the subject is accessi- ble , move in on it to make a close-up reading of that particular portion you wish to emphasize. Then press the self-timer/memory lock to the left; the light b ase d o n the main subject is now frozen.
COMPENSATION OF EXPOSURE - Continued R e p r o -c op y in g, s lid e - c opy in g a nd pho t om icrogr a phy Some exposure compensation may be necessary depending on the type of f i lm a n d t h e subject, or the origina l s l ide. The numbers in the tab l e be l ow show t h e exposure compe n satio n s in s h utter-speed steps.
DEPTH OF FIELD Depth of field refers to a zone within which blur (or lack of definition) will be negligible and everything can be accepted as being in sharp focus. Depth of field extends a greater distance behind the subject in focus than in front . It depends on two factors - reproduction ratio and aperture.
SELF-TIMER The built-in self-timer, usable for both automatic and manual-override shutter-speed settings, allows delayed exposures of approximately 10 sec. It activates when the lever is turned downward (counterclockwise) as far as it will go. When the shutter-release button is pressed, the timer starts.
MIRROR LOCK The reflex mirror must be l ocked in the up position when the battery is replaced, or during mic rosco pi c ph otogra phy, where eve n the minu - test shake mu st be pr eve nted. Th e mi rro r must a l so be l ocke d when using the Fisheye-Nikkor 6 mm f/5.
FLASH SYNCHRONIZATION The Nikomat ELW is designed to synchronize with various types of flashbulbs at almost all shut- ter speeds and with the speedlights at speeds up to 1/125 sec. Either a bulb or s peedlight flash unit slides over the accessory shoe on top of the pentaprism housing .
Remember that the camera's auto exposure con- trol works only with constant light sources such as sunlight or photo floods and not with an instan- taneous source such as a flashbulb or an electronic flash .

ACCESSORIES 53.
NIKON AUTO WINDER AW-l The Auto Winder AW-l is installed on the Nikomat ELW and makes possible the automatic film winding by one frame, of which speed is a ppr ox.
FIL TERS Nikkor lenses and Nikon filters are compatible with each other, Therefore, for best results, use Nikon filters, which are made of optical glass, ground and polished so that both surfaces are optically flat and parallel. They are available in both screw-in and series mounts, depending on the lens .
LENS HOOD The u se of a lens hood is recommended at all times to prevent extraneous light from striking the lens surface and causing flare or ghost, and also to protect the lens against damage . Nikon lens hoods come in four types depending on the lens : screw-in, snap-on, slip-in a nd built -i n.
OTHER ACCESSORIES Eyepiece correction le nses The nine eyepiece correction lenses are designed to perm it nearsighted or farsighted users to view and focus without t h eir g l asses . Available in - 5, -4, - 3, - 2, 0 +0.5, +1, +2 and +3 diopters, each representing the combined dioptry of the lens an d the finder .
58 Good camera care is common-sense care. Treat your Nikomat ELW as you would any valuable precision instrument. Although ruggedly construc- ted to stand the rigors of normal use, it may still be damaged by shock, heat, water or misuse .
