But the Recordata Back 4, on the other hand, is much more modern and uses quartz technologies to good advantage with addtional applications. It can keep vital dates or other data which can be recorded on images. A code system is also available to greatly simplify classification and retrieval of pictorial records.

Recordata Back 4.jpg
Recordata Back 4 is a cableless unit and coupled directly with the camera via the contact underneath the transport spool in the camera and thus, IF your OM bodies do not have a built-in databack terminal, you should not buy the databack and instead, look at the Recordata Back 3 which provides both features.

lcd6.jpg Hour, minute, (second) The hour and minute can be recorded directly on the film with the Recordata Back 4. NOTE: The second can also be 'optionally recorded. However, in some cases the second will appear blurred, as a result of it changing during the exposure.

lcd1.jpg Frame Counter. Up to six digits can be selected freely to form a desired code for the frame counter. This will advance one digit with each frame, establishing a sequence for the pictures taken

lcd3.jpg Fixed Code. Alternatively, the Recordata Back 4 can be programmed to imprint a fixed code directly on the photograph. The code selected and preset will then appear on all the frames shot, until the Recordata Back is reset.





Other photographic Possibilities with other accessories in the OM PhotoTechnical Group

3V Battery Holder 1

Not a common accessory for those who lives in the tropical belt like me. But may prove extremely useful for those who may require to shoot under cold climate. The external battery holder can be used to keep the electrical shutter for OM-2 or  OM-2n and metering system both OM1 and OM2 bodies (except the OM2SP whcih need a
version 2) running under extreme low temperatures. It consists of a Battery Holder that accepts the two battery cells from the OM2(n) and can be closed with the Battery Chamber Cap of the OM2(n), connected with a 147cm cable to a plug that can be screwed into the Battery Chamber of the OM-2(n).

This allows the photographer to keep the external battery holder in his pocket, protecting the batteries from voltage drop due to low temperatures. The OM-2(n) mechanics will function in temperatures as low as -50 degrees Celcius. This unit can only be used with the OM-2 or OM-2n. A Winder or Motor Drive cannot be used when 3V Battery Holder 1 is attached.

Note: 3V Battery Holder 2 is not usable with the OM-1, OM-1n, OM-2, OM-2n, OM-77 AF.

Perhaps one of the most exciting of these new fields is fiberscopy, which has revolutionized medical and industrial diagnosis around the mid seventies by permitting observation and photography of the internal body organs and of the insides of complicated machinery such as aircraft jet engines etc.

OM-Mount Endoscope Adapter * The OM System camera bodies are linked to the Olympus range of specialized fiberscopes via the Endoscope Adapter.


Used for mounting the OM body to the Olympus Endoscopes and Industrial Fiberscopes, The clear field type Focusing Screen 1-9 is recommended for use with this adapter.

OM-Mount Astroscope Adapter Links the OM body to a telescope for astrophotography. Direct objective photography and high magnification photography through the telescope eyepiece are both possible. Attachment is made to the draw tube eyepiece adapter of the telescope with the 36.5mm diameter, lmm pitch and 0.75mm pitch threads.

OM-Mount MTX Adapter * Bayonet type for mounting the OM body on the Olympus Operation Microscope MTX.

* Both OM-Mount Endoscope Adapter & OM-Mount MTX Adapter are marketed by subsidiaries of Olympus, Check with your local distributors for more details.


OM Mount Photomicro adaptor- H

An adapter to mount the OM body to other units of the Photomicro and Macrophoto Groups. It is also used to attach the OM body to the Auto Bellows, and is included with the bellows.

This adapter is used for mounting the OM body on the   Photomicrographic Systems PM-10-A / PM-10-M, the  Exposure Bodies PM-PBA / PM-PBM or the Macrophotographic Equipment PMT-35.
OM Mount Photomicro adaptor- L

A simple photomicrographic adapter for use of the OM camera bodies in conjunction with microscopes.

A special eyepiece adapter is required to mount an eyepiece into the photo tube of an ordinary microscope for objective magnifications up to 20X. The Varimagnifinder is recommended in conjunction with the Eyecoupler for sharp focusing in photomicrography.

OM-Mount Lens Adapter for Pen F

For connecting the OLYMPUS PEN F, FT, and FV cameras to the OM System interchangeable lenses and other units.

Supplement: Remember the popular half frame Olympus Pen-F ? Probably not. That was my first experience with an Olympus camera. The picture format is 18x24mm, which is half of the standard 35 frame - which means you can shoot double with a standard 36 film roll which suits a poor school kid like me back in the late sixties. However, the camera was introduced in 1963.

In many ways, it 'behaves' like a modern SLR where it takes interchangeable lenses, have a "M" and "X" sync socket to take flash bulb or electronic flash; it has a porroprism finder and comes with an optional Cds meter.

More ? It also has a depth of field preview which only works with the 38mm standard lens, shutter speed from 1 sec to 1/500 sec with a bulb mode.

The second model, Pen FT has even more improvement, the added on Cds cell is built-in and it is TTL now with a match needle indication inside the finder. Shutter speed control is from 1 second to 1/500 sec and it sync at ALL speeds. The film speed range is ASA/ISO 25-400 and the depth of field preview is via the lens. besides, a self timer was also added. The Olympus FV in 1967 is a Pen-F without Meter. All these half frame Pen-F camera is good for collection BUT not for practical usage - mainly because you may not able to locate any commercial lab that can process the prints. Other than if you have a darkroom on your own and shoot a lot of black and white and do the processing yourself, you may have to live with the pain ...
