A new and dazzling dimension...

THE NEW AUTOMATIC PENTAX K2DMD

The fascination of motor drive.

At two shots a second, your film consumption (and costs) can be fantastic ...but the action you'll be capturing will be even more fantastic. A left jab, a steal at second, a photo finish... the potential is enormous. The integral intervalometer lets you shoot at two frames per second, one frame per second, one frame every two seconds - or you can shoot single frames. You can set an exposure counter that will let you preprogram to shoot a set number of frames, and there's a remote triggering or a time-lapse timer. Potential... and more potential.

...a beautiful piece of equipment that will only be used, appreciated (and afforded) by a few photographers whose needs and skills now require this kind of horsepower.

How it got that way.

The K2DMD was designed as a system - a consideration, believe it or not, that makes it virtually unique in the world of motor drives. The Pentax engineers started with the requirements of a motor drive system... the demand of top photographers... as the basic design requirements. The result is a beautifully singular piece of equipment that we feel (showing little modesty) will become the standard for future motor-drive developments.

The camera portion is a beauty.

A quick, sure perfected bayonet lens mount. Automatic with shutter speeds of 8 to 1/1000 of a second. Manual override capability is there if you need it. For special effects - automatic under- or overexposure control. Metering is center-weighted, and fast with silicon photo diodes sensing the light level. The needles are superimposed over the shutter speed scale in the viewfinder. The f/stop is reflected from the lens barrel into the viewfinder via a tiny prism - you see exactly where you've set the aperture (and there are no strings to break). The f/stop turns red when you set the exposure meter to 1/4X, 1/2X, 2X or 4X - reminding you to return it to 1X when done with these special exposure situations.

More good news.

The Seiko engineers (superb watches) worked with Pentax engineers to design a unique metal focal plane shutter for the K2 cameras. This shutter made possible a very compact automatic camera with a high speed X sync of 1/125 of a second. A memory lock allows the K2DMD to temporarily "memorize" an automatic exposure. For a backlit portrait or other tricky lighting situations, it's a welcome feature. The memory lock also allows you to lock up the mirror and simultaneously cause the camera to "memorize" the exposure of the previous instant. This memory lock will function for about ten minutes, allowing you to take as many photos as you wish at the same "memorized" exposure. A low battery warning seems like a small idea but it can prevent missing big pictures. Besides, with this unit ... you "get it all."

Built-in viewfinder blinds that block out all the ambient light in critical situations, and a combination split/microprism focusing screen, are neat details that can make big differences.

That unique data back.

Rare, but to some, invaluable. There are no cords. It attaches quickly and securely to the camera and provides the K2DMD with the ability to be the only automatic motor drive that will record date, minute and second automatically. Your own notations can also be recorded on the film.

And even more.

You can use all 31 Super-Multi-Coated Pentax lenses on the new K2DMD. Since their introduction, these "flare tamers" have been considered by many to be the finest lenses in the world. With the addition this year of the perfected bayonet-mount, these truly elegant lenses are hard to beat.

Inexpensive they aren't, but going with a K2DMD is going first cabin and using it with lesse lenses would be ...rather gauche.

There are, for those of you with very large camera bags, almost 200 accessories that make this one of the most complete systems in the world.

Human engineering.

When you hold this camera in your hands - even the very first time - all the controls fall naturally into place. The camera feels as if it were custom made for you.

The edges that normally rest against your hands are beveled for a comfortable, more secure grip - so important for those long shooting sessions.

The raised white bump on the lens barrel allows you to change lenses quickly. Even in the dark. Less than a quarter turn locks the lens firmly in place.

Your Pentax dealer can show you still more of what makes the K2DMD feel as though it were made exclusively for you.

And that might add a new dimension to your photography and new quality to your pictures.

Manufacturer description #3

With the motor drive unit specifically designed for it attached, the Asahi Pentax K2 DMD is capable of consecutive exposures of two frames per second when using shutter speeds of 1/60 second or shorter (1/60 - 1/1000 sec.). Moreover, it is possible to combine the Data Back MD with the Pentax K2 DMD and Motor Drive Unit MD for the imprinting of data upon the film as it is automatically transported.

Manufacturer description #4

The K2 DMD is a fully automatic SLR camera built with precision and engineered for durability. Yet it maintains the ease of use and compact styling that has made Pentax cameras world renowned. Like the K2, the K2 DMD is fully automatic, utilizes a stepless electronic Seiko metal focal-plane shutter (with full manual overide capabilities) and an extremely fast and accurate silicon photo diode metering system. It also offers a full range of manual shutter speeds from 8 to 1/1000 second, plus B, electronic flash synch at 1/125 second, an exposure compensation dial that permits automatic over/under exposure up to 2 f/stops and a large, bright silver coated pentaprism for easy viewing and focusing.

In addition to motor drive capabilities, the K2 DMD incorporates several other features, unique in the line to the K2 DMD:

  • A full information viewfinder that shows whether the camera is being used on auto or manual; whether the exposure compensation feature is in use; what shutter speed has been selected and what lens aperture is in use.
  • Unique exposure control with use of a "Memory Lock." This enables the user to lock in an exposure reading and repositioning the subject in the viewfinder to compensate for harsh lighting conditions.
  • An automatic "Shutter Lock" that prevents the user from using the camera in the automatic mode when batteries are too weak.
  • An Eyepiece Blind.
  • Interchangeable backs.

Manufacturer description #5

The K2 DMD is first and foremost a precision camera designed for operating ease, accurate performance, durability, stability, and reliability. For unsurpassed handling ease it features two comfortable grips, dual trigger release buttons, and full exposure automation. Accuracy is assured by the utilization of the superb Seiko MF shutter and super sensitive silicon cells. The rugged K bayonet mount and 2 fps capability of the K2 DMD are ample evidence of durability, a characteristic long associated with Asahi Pentax cameras. All shutter speeds are electronically controlled for consistent performance; stability is maintained frame after frame.

Most importantly, the more than 15 year experience of Asahi Optical Company in designing and manufacturing motor drive cameras and systems has made it possible to create the ultimate in reliability: the Asahi Pentax K2 DMD, which is the pinnacle in precision motor drive cameras.

The powerful micro motor of the compact Motor Drive MD, the heart of the K2 DMD motor drive system, propels the film at a rate of 1/2 - 2 fps. Furthermore, a single touch is all that is required to changeover from consecutive to single-frame exposure operation. Also found on this unit are the exposure counter, trigger release, remote control socket, tripod socket, and rewind lever.

In addition to serving as a solid support and secure grip for the combination of K2 DMD and Motor Drive MD, Battery Grip M also houses the 12 penlight batteries which serve as the power source. As the batteries are stored in a cassette-type battery holder, the battery grip can be instantly loaded, or used batteries can be immediately replaced with fresh ones which have been preloaded in an additional holder. For added versatility, the grip has its own trigger release. Furthermore, after quickly and easily removing the grip from Motor Drive MD, the two can be connected with the accessory 3 meter power cable for remote control operation.

For compactness, the 15V rechargeable Ni-Cd Battery Pack M is ideal, while the 18V Battery Grip M offers the convenience of replaceable penlight (12) batteries. For the laboratory, Power Pack M, which utilizes ordinary AC current, is invaluable.

3 meter power cable is available as a standard accessory and, for remote control operation from extended distances, a 10 meter power cable is available as an optional accessory.

It is the combination of consecutive exposure capability of up to 2 fps with Motor Drive MD coupled with full exposure automation offered by the K2 DMD that make it possible for the photographer to capture the most elusive images. Horses rounding the bend and roaring into home stretch may race in and out of patches of shade, for example, but no matter, for the siIicon sensors of the K2 DMD instantly respond to the subtlest fluctuation in light, resulting in perfect exposure, frame by frame, even at 2 fps.

Connecting Battery Grip M to Motor Drive MD opens up new photographic opportunities. The camera can be concealed for wildlife or candid photography, or be fixed in a position normally inaccessible to the photographer, such as the tip of a flagpole on a tall building. Remote control also has a wide range of applications in industrial and scientific photography.

The Asahi Pentax K2 DMD is designed for those reaching for the stars... for those who want nothing less than the very best... for those who have their heart set on the pinnacle of precision cameras, for there is no other camera like the K2 DMD. Just take a look at the partial list of features shown below.

Seiko MF Shutter. Composed of five blades moving in a fan-line manner, this all metal focal plane shutter, which is exclusive to Asahi Pentax, is already world renowned for its stability in all temperature extremes. It is electronically timed, in both the auto and manual modes, for matchless accuracy, and synchronizes with electronic flash at 1/125 second, thereby alleviating the problem of ghost images in synchro-sunlight photography.

Viable Viewfinder. The K2 DMD viewfinder is alive with information. A mere glance tells whether the camera is set to auto or manual, whether or not exposure compensation is being used,* what aperture is being used,* and what shutter speed is automatically being selected. Additionally, a match-needle is also indicated for manual exposure control. And for focusing ease, regardless of subject type, there is a central split-image rangefinder surrounded by a microprism collar and outer ground glass collar.*

Full Exposure Control. For perfect exposure control, the superb Seikosha shutter automatically sets the correct shutter speed, in stepless increments, over a range of 1/1,000 - 8 seconds. For subtle changes in mood, contrast, and effect, as well as for correction in unusual lighting, it is possible to compensate the automatic exposure by up to ±2 stops. Another method of exposure control is utilization of the built-in Photo Memory Lock.* During automatic operation, the camera can be slightly lowered to exclude the sun, for example, and after first locking the automatic exposure, the camera can be repositioned to include the sun without obtaining underexposure. And as a final option, the complete range of shutter speeds, 1/1,000 - 8 seconds, is also available manually.

Safety Devices. There is a Shutter Release Button Lock to prevent accidental tripping of the shutter, a Shutter Speed Dial Lock to prevent it from being inadvertently moved off AUTO, a Battery Check Lamp to assure that batteries are replaced in time (and in the event that the batteries are not replaced when they should be, there is automatic "Shutter Lock"* which prevents the photographer from attempting to use the camera with bad batteries), Mirror Lock-Up provision to totally eliminate mirror shock at critical times, and when the motor drive unit is used, Automatic Stop occurs at the last frame, warning the photographer to replace film.

Additional Features. Additional features include an extra-large mirror to prevent mirror cut-off, built-on Hot Shoe with a built-in circuit breaker to eliminate the possibility of shock, a Self-Timer which can be interrupted and by-passed, a Depth of Field Preview Button, a silver-coated pentaprism for brilliant viewing, lenses that can be instantly and correctly aligned with the K bayonet mount even in the dark, a Film Advance Lever with a short throw of 135°, a built-in Eyepiece Blind* to prevent extraneous light from entering the eyepiece when the camera is used in the auto mode and away from one's eye, and most importantly, interchangeable backs* and provision for motor drive.*

* Features not shared by the Asahi Pentax K2, but found exclusively on the K2 DMD.
