The OM System Macro photo Group is magnificently comprehensive and almost miraculously manageable. Simplicity of operation is enhanced beyond measure by the OM-2's TTL Direct "OTF" Light Measuring, which obviates the need for highly critical exposure calculations, and permits completely automatic close distance flash photography.In fact, the new TTL Flash exposure control has made Macrophotography such as joy to use and provide photographers more confident to explore new creative possibilities rather than spending time on exposure calculation.

In fact, the Photomicro and macrophotography has been one of the strongest elements among others to put Olympus comfortably on the driving seat in this specialized field among all competitions. They have the largest, most extensive and sophisticated photographic equipment to offer and handle virtually any tasks, regardless it is for industrial, scientific, research or for recreational photographyThere are accessories that put you through a range from infinity to over 12 times (12X) life size, the group supplies no less than seven special macro lenses.

Although the 135mm F4.5 and 80mm F4 have independent fine focusing for extra convenience, these and the new 38mm F2.0 and 20mm F2.0 along with the older versions of f/3.5 are exclusively for use with the Auto Bellows or a well thought-out macro accessory called

Telescopic Auto Tube 65-116.
The unique Telescopic Auto Tube is basically a combination of a extension tube, with a zoom ring design which substitute a few of the extension rings with the extra benefit of very flexible variable extension is a highly innovative and practical accessory which permits far greater portability in high magnification macro work, with the added benefits of fully automatic aperturing, smoother and quicker extension, and increased toughness.


Used with the 135mm F4.5 and the T10 Ring Flash 1 (which also accepts a unique cross polarizing filter to minimize reflections), it affords unrivaled performance, with TTL "OTF" Auto flash and a free choice of magnifications and lens apertures, in medical, laboratory and outdoor macrophotography.

Where in the field of macrophoto relates, OM System provides a very very comprehensive and almost a complete solution for essential system accessories, which includes filter, lenses, macro flash and even copy stands for copy work, high magnification laboratory work, etc., trans- or epi-illuminators, slide copier, stage plates and glasses, filters, Lieberkiffin reflectors and much besides, including the 26-unit Macrophotography Equipment PMT-35 which contains everything normally needed for work from 0.45x to 16.5x magnifications.

For life size copy work, the 80mm F4 can be mounted on the Telescopic Auto Tube which can provide a continuous magnification range from 1/2x to life size, or life size to 2x together with the Close-up Lens 80mm Macro. Low magnification close-up photography is also catered for with a few alternatives on auto extension tubes and close-up lenses. Impressive ? I do.

However, NOT all SLR manufacturers (even apply to third party lens manufacturers) offer true macrophoto lenses. Among few of the top camera makers, Canon, Minolta and Olympus are the rare few offer such system accessories. The Olympus is the ONLY camera manufacturer that offer complete solution include high end photomicro system and carry the most extensive of such dedicated equipment such as microscopes, lenses and other accessories in this category, Canon and as well as the Minolta has such optical solutions (Minolta has two bellow lens in 50mm and 100mm and additional two bellow-micro photo lenses of 12.5mm and 25mm).

Another segment where Olympus has always been strong at is photomicro-photography. As one of the world's leading makers of microscopes with a product line from simple models to enormously sophisticated biological, metallurgical, surgical and system microscopes, Olympus has quite a solution to such needs in photomicrography.

<<-- It is clearly Olympus as the edge in this specialized field with its widest selection of photomicro group of accessories.

Among the units in this group are automatic and manual exposure bodies with the Olympus OM-1(OM3(Ti) and more choices in the electronic bodies such as older OM2(n), OM2SP, OM4, OM4-Ti etc..), There is an automatic exposure control box to regulate color temperatures, a vibration-proof stand, various focusing units, adapters, etc. Photomicrography is immensely simplified by the OM-2(n) or later automatic bodies' TTL Direct 'OTF" Light Measuring method. Another remarkable system accessory that really made your eyebrow raised was Olympus's automatic film advance section. By vastly reducing size, weight and complexity while greatly improving speed responsiveness and other performance and handling characteristics, the OM System became the first to offer a full-fledged motor drive both eminently suitable for amateurs and unprecedentedly practical for professional photographers.

The Total Mode Automation of the OM-2 makes it a still more effective tool by assuring that every frame is perfectly exposed even at the exceptionally high maximum speed of five-frames-per-second (5 fps), however sudden or drastic the changes in composition and light intensity.

<<-- You must have been thinking the Motor Drive 2 mounted on the OM4(Ti) will not be usable on the 1975's OM2(n). No, it is still workable, except may be minus the power rewind function.

Both the older Motor Drive Unit 1 and current Motor Drive 2 are extremely well made Drives, compact yet rugged, they are fast and easy to setup and use, not to mention they are also extremely versatile. Both can be screwed to the base of the camera in seconds. Power and control functions are supplied by a choice of separate units: either [he Ni-Cd Control Pack 1(2), the battery powered, clip-on 'Control Grip I (2) or the AC Control Box which also provides an intervalometer. For extended use the 250 Film Back is available along with magazines and loader.


The OM Motor Drive would really made you wonder just how can Olympus managed to designed such a high performance professional grade motor drive in such a compact and lightweight form. Illustrated with comparing modern AF SLR of "equivalent" performance.---- >>>

Both these drives are extremely versatile. The OM-2's Centralized Control System makes sure the film is advanced the instant the shutter closes, never before, no matter whether the exposure time is 1/1000 sec. or a full 120 seconds.

In either "SEQUENCE" or "SINGLE" mode just pressing the release button initiates the full motor drive cycle, which ends with the film advanced ready for the next shot.

This is a distinct improvement over systems that advance the film in "SINGLE' mode only after the button is released. When the film is completed the motor drive is automatically disengaged. In fact, this has inspired Nikon to upgrade their Motor Drive MD-11 to MD-12, which has patched this flaw in operation. The small, economical Winder 2 boasts performance in a league with many motor drives, with a maximum speed of 2.5 frames-per-second in either "SEQUENCE" or "SINGLE" mode. Although the motor, power and control functions are integrated in a single unit, an extension power pack is provided for battery protection in extreme temperatures and the power winder is compatible with the 250 Film Back and other units.

In every other respect the Winder 2 features the same sophisticated Centralized Control operation as the motor drive including automatic synchronization at any shutter speed and provision for wired or wireless remote control operation.

<<<<----- Some OM2 bodies still carried with the "MD" plate to diferenciate those bodies that enable attchment of motor drive unit.

There is also another group of accessories that called "Photo Technical Group" in the OM system. Units provided include an astroscope adapter and a variety of other adapters for special applications, and older cord based Recordata Backs 1, 2 and eventually olympus realized the potential of digital technology and introduced a LCD display and cordless version, Recordata Back 3. The Version 3 forms the basis for the current model, Recordata Back 4, which provides even more functionality with those updated OM SLRs.

The Recordata Back 3 can be attached to the camera permanently. It is designed for recording year, month and day or day, hour and minute, and features a quartz mechanism that need only be set once to give perfect time keeping including automatic memory of months and leap years up to 2009.<<-- Olympus's Recordata Back 1used only cable connection.

The Recordata Back 2, set manually, provides four sets of numerical and alphabetical symbol codes. Newer and current version Recordata Back 4 which would require databack terminal only is NOT usable with OM2 bodies. Anyway, personally, I would conclude the Databack section within the OM system is the weakest link as the current Databack 4's life span for its usable programmed dates are only valid until year 2009 and Olympus still doesn't seem to care too much with the limited validity available. If you cannot live without one for an important assignment and must bright only your old trusty OM1 and OM2, look for the older Recordata Back 3. * More detailed info is available on Recordata Back Version 1-4

The Case Group To give full protection and instant accessibility to OM System cameras, lenses and other equipment the Case Group makes available a large selection of soft, semi-hard and hard camera cases, a special camera case for use with the Recordata Back 3, lens pouches and compartment cases. A special partitioned insert fits into the large compartment case to. securely hold motor drive units including the 250 Film Back 1.

Naturally, clear vision and viewing comfort is a prerequisite for taking clear pictures and extensive time using these equipment. Olympus puts special emphasis on assuring an ideal viewfinder image in all conditions. Performance of the large, bright finder in OM cameras is further enhanced by a range of no less than 14 different focusing screens for ideal focusing and composition with fisheyes, super telephotos, shift and macro lenses and even fiberscopes.

The Finder Group also features the Varimagni Finder for angle viewing either at 1.2x magnifications of the whole picture area or 2.5x of the central part. Other units are a range of diopttic correction lenses, an Eyecup and an Eyecoupler.* More detailed info is available on Viewfinder Accessories and the 14 types of Focusing Screens
