  THE BENEFITS OF LX PHOTOGRAPHY

 
IDM Light Measurement
The heart of the Pentax LX is the Integrated Direct Metering (IDM) system which employs a Silicon Photo Diode to measure light directly off the film plane for superb accuracy in exposure control. Incorporating a special pattern on the shutter curtain for high speed measurements and a unique secondary mirror which transmits information to the LX viewfinder almost to the precise moment of exposure, the IDM system of through-the-lens light measurement assures accuracy even under the most difficult and changing lighting conditions. The need for exposure compensation when using system accessories such as focusing screens or interchangeable finders is virtually eliminated.4www.butkus.org

Interchangeable Finders and  Screens
The LX System includes a wide array of interchangeable viewfinders and focusing screens to meet the challenge of any photographic situation. The unique FB-1 Systems Finder features optional viewing accessories to create a viewing system within a system, and the standard FA-1 Finder features a built-in TTL "X" synch hot shoe which lets you take full advantage of the IDM light measurement system (See pages 46 to 49)

Titanium Electro-Mechanical Shutter
The LX camera features an extremely broad range of shutter speeds. The titanium electro-mechanical shutter mechanism delivers electronically-controlled stepless speeds in the automatic mode from an amazingly fast 1/2000th second down to 125 seconds, provides manual speeds from 1/2000th second to 4 seconds, and features a special design which provides manual speeds from 1/2000th second to "X" even when the batteries fail (see page 11,18).

TTL Integrated Automatic Flash Control
Integrated Automatic Flash Control with the Pentax AF-280T and AF-400T Flash Units makes flash photography exceptionally simple and accurate even with difficult bounce lighting or at close subject distances. Because the IDM system measures light at the film plane, the LX works with TTL flash models to measure both ambient and electronic flash lighting for exposure accuracy regardless of the lens aperture. These units also feature automatic "X" synchronization and a visible exposure check and ready light in the viewfinder when the capacitor reaches full charge (see page 38).

Rugged, Lightweight, Compact Design
Designed to handle the most rugged and demanding professional assignments, the LX remains incomparably compact and lightweight among the 35mm SLR camera systems. Its specially contoured body design allows it to rest comfortably in your hands even with Motor Drive or Winder attached. Weighing only 803 grams (28 ounces) with normal f/1.4 lens and standard Finder, the LX is designed to go anywhere and capture the action with the ultimate in handling ease and carrying convenience. Special gaskets and linings at key points throughout the body make the LX extra durable and resistant to heat, shock and moisture.

The LX is backed by a comprehensive system of accessories with more than 40 Super-Multi-Coated Pentax lenses and hundreds of attachments to meet virtually any picture-taking need. (seepages 56-59).

BATTERIES
Inserting the Batteries

The electronic systems of your Pentax LX operate on two 1.5-volt mini batteries which are packed separately with your camera. To insert the batteries, first remove the battery chamber cap at the base of the camera by inserting the edge of a coin and turning in the direction of the arrow. Place the two batteries in the chamber as shown making sure the positive (+) sides face up.

Replace the chamber cap and tighten securely.

Battery Check

After inserting the batteries it is often helpful to make a quick check to see if batteries are inserted properly and the camera's electrical systems are functioning. To check battery voltage, activate the camera's metering system by pressing the shutter button partway and observe the viewfinder LED shutter speed display. The shutter speed LED will glow continuously if normal voltage is being supplied.

Low Battery Warning

When batteries become weak the viewfinder shutter speed LED will begin to flicker. Although all electronic systems will continue to function accurately until the display goes out completely, both batteries should be replaced promptly to ensure uninterrupted operation of the camera's electronic exposure controls.


Operating the Camera Without Batteries

When the LED shutter speed display no longer lights, batteries are dead. However, the LX camera incorporates an electro-mechanical shutter system which allows the photographer to continue taking pictures over a broad range of shutter speeds even when the batteries no longer function due to exhaustion or temporary failure from temperature extremes. Should battery failure occur while shooting within the camera's mechanical shutter speed range (i.e., from l /2000 second to "X") no interruption of camera operation will take place. However, should batteries fail while operating in the "Automatic" exposure mode or within the electronically controlled shutter speed range (from l /60 second to 4 seconds) the mirror will automatically lock up as a warning.4www.butkus.org

To continue picture-taking, simply turn the shutter speed dial to any of the mechanically operated settings (l /2000 second to "X").

NOTE: Should you wish to save the exposure being made when the mirror lock-up occurred, before changing the shutter speed dial, first cover the lens with the lens cap. Then, release the mirror as described above and press the film rewind/multiple exposure button at the base of the camera. Advance the film and take the picture.

IMPORTANT! NEVER THROW USED BATTERIES INTO FIRE OR EXCESSIVE HEAT TO PROTECT AGAINST EXPLOSION. Al WAYS KEEP BATTERIES OUT OF THE REACH OF CHILDREN.

Battery Care

Under normal operating conditions, the two 1.5-volt alkaline mini-batteries in your camera will last several months. Should batteries require replacement, replace BOTH at the same time with equivalent 1.5 volt alkaline or silver oxide mini-batteries.4www.butkus.org

Keeping a spare set of batteries on hand can help you avoid the inconvenience of battery failure during busy picture-taking sessions, especially when shooting in cold climates where failure due to extreme temperatures is not uncommon. Protect your camera from leakage by removing the batteries whenever the camera will not be in use for long periods of time.

CASE A CASE AND STRAP STRAP

Attaching the Strap
The strap which accompanies your LX can be used in two ways. Before attaching the strap, press the twin tab of the fastener (Tab A) with the edge of a coin until the single tab (Tab B) protrudes.

To Carry the Camera Horizontally
When carrying the camera around your neck or when using the Standard Eveready Case, first attach one of the strap fasteners to either Accessory Lug (C) or (D) and press Tab (B) with a coin until Tab (A) protrudes, thereby locking the fastener to the lug. Repeat with the other fastener.4www.butkus.org

To Carry the Camera Vertically
When you wish to carry the camera shoulder style, unlock the fastener attached to Accessory Lug C by pressing Tab (B) until Tab (A) protrudes. Then, remove the fastener and attach it to Accessory Lug (E)

IMPORTANT: Before carrying the camera by the strap, jiggle the fasteners back and forth while pulling on the strap to make sure that the fastener is locked securely to the accessory lug. If not locked properly, the strap could come off and damage your camera.

CASE
The standard Eveready Case for your LX features a half-moon lock as added protection against coming open while carrying the camera. To remove the case front cover, turn the cover a full 180° as shown so that the fastener unlocks, and separate.

CAUTION: Do not try to remove the front cover without first turning it so that the fastener unlocks (this could weaken or break the fastener).
The Pentax LX system includes different types of accessory grips. Accessory Grip B is hand-contoured for added balance and handling convenience. For more precise requirements, the Accessory Grip A can be shaped to meet the photographer's individual needs using a whittling knife or similar instrument and sandpaper to smooth out the rough edges.
 To attach either grip, first place the grip over the accessory lug (C) making sure the screw aligns with the socket at the bottom front of the camera (F). Tighten the screw using a screwdriver or coin.4www.butkus.org

 

USING SCREW MOUNT TAKUMAR LENSES
Super-Takumar and SMC Takumar screw-mount lenses can be attached to your Pentax LX by using the Pentax Mount Adaptor K. When using this accessory, however, the automatic diaphragm of the lens will no longer function and meter readings must be made with the lens aperture stopped down.

Mounting The Adaptor
After attaching the Adaptor K to the lens until it seats firmly in place, align the red dot on the Adaptor with the red dot on the camera's lens mount. Insert the lens and rotate the adaptor/lens combination clockwise about 1/4 turn until in clicks into place. The Mount Adaptor K is now fully engaged and screw-mount lenses can be interchanged freely without further adjustments.

Removing The Adaptor
After removing the lens, press the adaptor release (A) with your thumbnail or a pointed object such as a ballpoint pen. Turn the Mount Adaptor K counter-clockwise until you feel it release and remove it from the lens mount. Please note that the lens release button (B) serves no function when using this adaptor.


MAINTAINING THE CAMERA

·Always keep the viewfinder eyepiece, finder-surface, lens and filters as clean as possible. Remove loose dust and dirt by first using a lens blower and then brushing gently with a camel's hair lens brush. Avoid scratching optical surfaces by trying to wipe away granular dust or grit. Smudges and fingerprint marks should be carefully wiped off using lens tissue or a clean soft cloth. A clean, previously-washed plain handkerchief is particularly good for this purpose. In extreme cases, use a good quality lens cleaning fluid to remove stubborn smudges.4www.butkus.org

·Never touch the mirror or the shutter curtain, particularly when changing the interchangeable focusing screen. When changing screens, use the pincette as described on page 48. Minor dirt or spots on the mirror will not affect the clarity of your photos.

·Whenever possible, carry your camera with its neck strap or in a carrying case or gadget bag. Accidentally dropping the camera can cause serious damage in the internal mechanisms.

·Be particularly careful not to drop the finder when changing viewfinder models. Slide the finder back slowly to avoid damage to the optical surfaces.

·Although your LX has specially-designed gaskets to minimize the possibility of damage from moisture, it is not waterproof. Several places exist where water can get inside and damage internal mechanisms. Protect both the camera body and lens from rain or splashing water. If the camera should get wet, dry it off immediately when a clean soft cloth. If it becomes submerged in salt water, place it in a pail of fresh water to retard the onset of corrosion and take it immediately to a Pentax Service Center to determine if repairs can be effected.

·The automatic shutter of the LX will operate over a temperature range of 50°C (1 22°F) to -20°C (-4OF), and the mechanical shutter will function from 50°C (122°F) to -30°C (-22°F). To assure reliable operation of the automatic shutter in low temperatures carry spare batteries.

·Always store your camera in a cool, dry, clean and well-ventilated place when it is not in use to avoid the possibility of damage due to condensation buildup. This is particularly important in areas of high humidity. Keep the camera in its case or in a gadget bag with the lens cap on as added protection. Condensation also builds up when bringing the camera into a warm room from the extreme cold, or vice versa. This can be prevented by immediately placing the camera in it's case, bag or wrapping so that temperature changes gradually.4www.butkus.org


LX INTERCHANGEABLE VIEWFINDERS
The Pentax LX System includes an array of optional interchangeable viewfinders designed to meet almost any photographic situation. Because the LX Integrated Direct Metering system measures light at the film plane, no exposure compensation is required with any of the LX Finder models.

Model FA-1 Eye-Level Pentaprism Finder
The standard LX viewfinder, the FA-1 combines bright eye-level pentaprism viewing, built-in diopter correction, full data viewfinder display and a built-in "X" hotshoe. Built-in diopter correction is available for the - 1.5 to 0 diopter range. Additional correction is possible with the correction lens adaptor and SMC correction lenses. Check your eye doctor for the diopter range best suited for your needs.

 

Model FA-1W Eye-Level Pentaprism Finder
The same features as the FA-1 with an extended built-in diopter correction range from - 3 to +1 inclusive.

FD-2 Standard Eyepiece --Provides a convenient 45° viewing angle ideal for microscope use or copy work.


CHANGING THE FOCUSING SCREEN
To change the LX Focusing Screen, use the pincette supplied with your new focusing screen. Insert the head of the pincette against the top plate of the mount so that the two ear-like tabs rest against the indentation in the plate as illustrated. Then, gently lift upward on the handle of the pincette until the focusing screen frame drops down.4www.butkus.org

CAUTION: Move the pincette very carefully. If the screen doesn't release immediately, do not exert excessive pressure: a slip could damage either the focusing screen or mirror surface.

Squeeze the handle of the pincette and very carefully sandwich the tab of the focusing screen between the two sections of the head. Lift the screen out of the frame and place it in the container for protection.4www.butkus.org

To install the new focusing screen: Pick up the screen by the tab with the pincette as described above and place it on the focusing screen frame with the tab on the right hand side as shown. Push the frame back to its original position until it locks in place.

IMPORTANT: Only handle the screen with the pincette and by the tab only. Never wipe screen surfaces with clothing or a cloth to avoid damage. Remove dust particles with a blower or camel's hair brush.

The LX system includes twelve focusing screens to provided focusing aids for a wide variety of general and specialized applications.

WINDER/MOTOR/ DRIVE SYSTEM
With the Winder LX or Motor Drive LX, you'll always be ready to capture even the fastest action. Whether its sports, news or active children at play, the automatic film transport capabilities provided by these accessories help you keep your eye on the action and the shutter ready to fire. Even changing film is made simpler and faster through the built-in automatic rewind feature which rewinds a full 36 exposure film cassette in just seconds.
 
Winder LX
Powered by four 1.5-volt AA batteries, the Winder LX can record the action at speeds of up to 2 frames per second at the continuous ("C") setting or provide single frame exposures with automatic film advance at "S" while retaining full synchronization with all LX camera shutter speeds (except "B"). The compact, lightweight unit attaches quickly and easily to the camera's tripod socket and can be fired by the camera shutter release or the optional remote control unit. An LED flashes when the film stops automatically at the end of the cassette and the automatic rewind feature rewinds a full 36-exposure cassette in about 1 15 seconds.4www.butkus.org


Motor Drive LX
To meet the challenge of professional high speed sequential applications, the Motor Drive LX provides automatic film advance at speeds up to 5 frames per second in "High" or as slow as 0.5 frame per second in "Low." Other features include a single-frame setting, full synchronization with all camera shutter speeds (except "B"), an end of film LED and automatic film rewinding (36-exposures in 8 seconds).

The Motor Drive LX mounts quickly to the base of the camera via the tripod socket. The shutter can be triggered by the camera shutter release button, the release button on the Battery Grip M or by remote control via the optional remote control unit. An optional 250-exposure bulk film back is also available.

The Motor Drive LX provides a wide variety of power options including the Battery Grip M for penlight batteries, the Ni-Cad Battery Pack LX for rechargeable nickel cadmium cells or the Power Pack M for standard AC current.

 


DATA RECORDING SYSTEM

By taking advantage of the fully interchangeable back of your Pentax LX, the camera can quickly and easily be converted into a sophisticated data camera capable of recording valuable information directly on the finished photograph. This can be a valuable tool in scientific and biomedical photography, in architectural and industrial applications to record progress of a given project, in government and evidentiary photography, or simply for recording the growth of the family as years pass.



 
Dial Data LX

The Dial Data LX provides thee alpha-numeric wheels indexed in numbers from 0 to 36 and in letters from A to O. This accessory is particularly good for recording the year-month-day a photograph is taken as well as for recording exposure information such as shutter speed, aperture or frame number directly in the corner of the frame. The Dial Data LX is powered by three 1.5-volt Alkaline or Silver Oxide mini-batteries and can be set for two ASA ranges for color film (ASA 25-50 and ASA 64-400) as well as for black & white films. A built-in battery check and confirmation LED are also provided.4www.butkus.org

 


 
Watch Data LX
The unique Watch Data LX allows you to record the face of a timepiece directly in the corner of your photograph to display the day of the month, hour, minute, and second the photograph is taken. The central portion of the watch itself provides a ground glass portion where additional information can be penciled. Three settings are provided for black & white film (ASA 100, 200 and 400) and one setting for color film (ASA 160). The Watch Data LX is powered by a single 6-volt Alkaline or Silver Oxide Battery and provides a built-in confirmation LED and battery check.


Using the Film Blind
When using the Watch Data LX, it is necessary to lower the special film blind to block out the corner of the film for recording purposes. Before taking pictures with this back, open the camera and lower the blind by turning the small thumbwheel on the lower right hand side of the shutter counter-clockwise. Remember to return the film blind to its normal position before resuming non-data photos. MAKE SURE YOU AVOID TOUCHING THE SHUTTER CURTAINS.

Note: The film blind is used only for the Watch Data LX and need not be lowered when using the Dial Data accessory.



PENTAX LENS LENS SYSTEM
The over 40 SMC Pentax Lenses which make up the Pentax Bayonet Lens System feature the latest in computer designs and represent the superb quality that has been associated with Pentax optics for over 60 years. The available selection runs all the way from 15mm ultra-wide-angle to 2000mm super telephoto and offers an assortment of special purpose lenses including eight zooms, plus fisheye, macro, bellows and shift lenses. All SMC Pentax Lenses feature exclusive Super-Multi-Coating to minimize flare while increasing light transmission and enhancing resolution, contrast and color balance. Superb Pentax quality control assures matched color balance throughout the lens system and the utmost in mechanical and optical reliability.



*  the photo below shows two kinds of optical groups, each made up of two glass elements cemented together. The group on the left has been Super-Multi-Coated; significant reduction in the amount of reflection is readily apparent
 
SUPER-MULTI-COATING (SMC)

SMC Pentax lenses evidence very low levels of flare, virtually no ghost images and offer excellent image reproduction and color rendition. The experienced pro can literally take pictures directly into the setting sun with them and obtain exciting results.

The high quality of SMC Pentax lenses is the combined product of Pentax space-age optical engineering and SuperMulti-Coating, Asahi Optical's own unique 7-layer lens-coating process that eliminates both flare and ghost images, and transmits more light for vivid colors. Reflection ratio is a mere 0.2%, while reflection control is nearly flat against the whole range of visible light. These two factors result in improved performance in almost all lighting situations.

   

* With Super-Multi-Coating, flare and ghosts and other unwanted reflections are almost totally eliminated; images are further sharpened by elimination of side-lighting. With ordinary coating, flare is induced as direct sun rays trounce off of successive lens surfaces.
 
Moreover, recently improved multi-coating techniques entail the coating of most glass surfaces within the lens, including some which were previously cemented together, and others which were only single-coated previously. The effects of Super-Multi-Coating are particularly outstanding with zoom lenses, which have a great many individual lens elements and transmit less light than other lenses. Without any coating a zoom lens transmits about 17.5% of the light. With conventional coating, transmission increases to 66.3%, while with Super-Multi-Coating, transmission is 95.3% -- about 50% brighter than with conventional coatings.4www.butkus.org


Wide Angle Lenses
Whether you're shooting a panoramic landscape, a party or the cover of an annual report, the Pentax SMC Lens System lets you select the focal length and features just right for your needs. From the incredible effects of the SMC Pentax 15mm f/3.5 to the classic wide angle view of the SMC Pentax-M 35mm f/2.8, over 10 different focal lengths provide the versatility in angle of view, lens speed and styling required to capture the unusual world of wide angle images.



Telephoto Lenses
Fifteen focal lengths comprise the comprehensive Pentax SMC Telephoto lens group allowing the LX photographer to choose from portraits at 85mm, candids at 200mm, wildlife at 2000mm or just about anywhere in between. Designed to complement the lightweight, compact styling of the Pentax LX and all other Pentax compact 35mm SLR cameras, these superb telephoto and ultra telephoto lenses afford the photographer with the flexibility to meet al most any photographic challenge with complete confidence.


Zoom Lenses
The eleven lenses in this lens group are truly representative of the Pentax dedication to optical versatility and handling ease. Whether you're an architectural photographer requiring the wide angle perspectives of the SMC Pentax-M 24-35mmf/3.5, a nature lover who appreciates the power of the 135-600mm f/6.7 zoom or just an all-around photographer looking for the flexibility provided by the 40mm f/2.8-80mm f/4 Close Focusing Zoom, there's a Pentax zoom that's ideal for you.


Special Purpose Lenses
When the unusual calls and the demands require a special kind of handling, the SMC Pentax system is there. Whether you're exploring the canyons etched in the face of a grain of sand with a bellows, capturing a life-size image of a cherry blossom, or taking advantage of the unique perspectives of the 17mm fisheye lens or the perspective control provided by the 28mm shift lens, you can be confident that the images will be recorded with superb resolution, contrast and color balance.

All Pentax cameras purchased through authorized bona fide photographic distribution channels are guaranteed against defects of material or workmanship for a period of twelve months from date of purchase. Service will be rendered and defective parts will be replaced without cost to you within that period, provided the equipment has not been abused, altered, or operated contrary to instruction. Because the tolerances, quality, and design compatibility of lenses other than Pentax lenses are beyond our control, damage caused by use of such lenses will not be covered by this warranty policy. The manufacturer or its authorized representatives shall not be Liable for any repair or alterations except those made with its written consent and shall not be liable for damages from delay or loss of use or from other indirect or consequential damages of any kind, whether caused by defective material or workmanship or otherwise; and it is expressly agreed that the liability of the manufacturer or its representatives under all guarantees or warranties, whether expressed or implied, is strictly limited to the replacement of parts as herein before provided.

Procedure During 12-month Warranty Period
Any Pentax which proves defective during the 12month warranty period should be returned to the dealer from whom you purchased the equipment or to the manufacturer. If there is no representative of the manufacturer in your country, send the equipment to the manufacturer, with postage prepaid. In this case, it will take a considerable length of time before the equipment can be returned to you owing to the complicated customs procedures required in Japan in importing and re-exporting photographic equipment. If the equipment is covered by warranty, repairs will be made and parts replaced free of charge, and the equipment will be returned to you upon completion of servicing. If the equipment is not covered by warranty, regular charges of the manufacturer or of its representatives will apply. Shipping charges are to be borne by the owner. If your Pentax was purchased outside of the country where you wish to have serviced during the warranty period, regular handling and servicing fees may be charged by the manufacturer's representatives in that country. Notwithstanding this, your Pentax returned to the manufacturer will be serviced free of charge according to this procedure and warranty policy. In any case, however, shipping charges and customs clearance fees are to be homed by the sender. To prove the date of your purchase when required, please keep the receipts or bills covering the purchase of your equipment for at least a year. Before sending your equipment for servicing, please make sure that you are sending it to the manufacturer's authorized representatives or their accredited repair shops, unless you are sending it directly to the manufacturer. Always obtain a quotation of the service charge, and only after you accept the quoted service charge, instruct the service station to proceed with the servicing.

This warranty policy does not apply to Pentax products purchased in the U.S.A., U.K., or Canada. The local warranty policies available from Pentax distributors in those countries supersede this warranty policy.
