Olympus T Power Control 1 (T1) Macro flash with the OM System provides great portability and handling. One major reason is that the T Power Control 1 introduced later that has extended OM flash options, which all the macro flash units use in common, slips into the camera hot shoe just like a normal compact flash unit. The desired macro flash is then mounted on the lens and plugged in. The whole assembly of camera, auto bellows or telescopic extension tube, macro lens, flash and, when needed, motor drive becomes a single, easy to-carry, easy-to-handle unit. The Unit can be mounted to the accessory or fixed hot shoe, this unit feeds power to the T-series macro flashes: T8 Ring Flash 2, T10 Ring Flash 1, T28 Macro Single Flash 1 and T28 Macro Twin Flash 1.

It looks like and is about the same size as the T32. But with respective OM bodies, it reacts differently based more on the camera's function rather than control by flash. For an example, it works in TTL flash modes with OM2 bodies; with OM-4Ti or OM3Ti, the unit switches automatically between TTL Auto and Manual Flash according to the camera setting while with the mechanical OM1 and OM-3, it operates on Manual only. |
TTL "OTF" Auto makes close-up and macro flashphotography easier than ever: no need to set ASA rating or aperture on the unit, and light fall-off due to lens extensions is automatically calculated in the exposure. The charge/correct auto flash signal can be seen both in the viewfinder and on the back of the unit. With the calculator panel positioned in reverse, it alos greatly simplifies Manual flash control. Manual flash calculator panels are optionally available for all combinations of macro flashes and macro lenses. The T Power Control 1 looks like the T32 flash unit, but instead of a reflector at the front, it has a connection for the separate flash heads. This can be an invaluable flash accessory for those who involves in macro photography because it simplifies the process of flash exposure calculation for extension of macro lenses or bellows units which otherwise would require complicated calculations in order to achieve satisfactory exposures. However, in operation, it works either in TTL flash more or total manual flash exposure control. There are three reversible panels where one is designed to work with the 50mm while the rest is for 80mm and 135mm macro lens head. (More info for Power Control 1)

Olympus has the WIDEST selection of macro flash units among ANY manufacturers. Most accessories are very well thoughtout and functional in its design, but most of all, they are being designed as a system and you can freely adapt them to your needs without too much problems of system incompatibility. <<<< ----Backview of the T Power Control looks very similar to a normal T32 flash. |
Power sources: 1) self-contained: 4 1.5V AA size batteries; 2) 4 1.5V size C batteries in Power Bounce Grip 2; 3) Electronic Flash AC Adapter 3. The system grew and developed into a full scale macro photo group during the mid eighties where most other camera manufacturers were kept very busy introducing autofocus SLRs while Olympus was contented centered and strengthen the system resources with their manual focus SLR models. Outlined below are some of of such flash units designed specifically for macrophotography:
 |
Olympus T10 Ring Flash 1 One of the older designed, used with the T Power Control 1 to provide shadowless lighting at extremely close camera distances while maintaining TTL OTF flash. It is a multipurpose ring flash that fits on the front of any lens with a 49mm or 55mm filter size and ideally suited for medical, scientific and outdoor action photography. It is suitable for virtually all OM Zuiko lenses between 50mm and 200mm focal length, but especially useful with the range of OM System macro lenses. The big breakthrough introduced by this unit was TTL Auto Flash where it assures a higher successful macro flash photography than ever before. It features eight built-in modeling lamps for composing and focusing dark subjects. The modeling lamps are powered by the separate 6V Power Pack 2. Alternatively, both flash and modeling can be powered together by the AC Adapter 3. This flash setup works in tandem with the T Power Control 1 (containing 4 AA batteries, booster, capacitor, etc.). |
Having two threads, the T10 can be screwed into either 49mm ø or 55mm ø lenses. This excludes the manual macro lenses 20mm/F3.5 and 38mm/F3.5. The modelling light is powered by the 6V Power Pack 2 or AC Adapter 3. The modelling light in the form of eight electric bulbs are built into the flash surface to facilitate focusing and composition with dark subjects. With the aid of the optional Ring Cross Filter POL, existing of an outer polarizing filter which will cover the flash surface,orientated at right angles to an inner polarizing filter (covering the camera lens), the ring flash reproduces glossy objects, minimizing undesirable directly reflected light.
Ring Cross Filter POL It is a unique polarizing filter design made especially for use with the T10 Ring Flash 1. It is used for minimizing direct reflections. The outer section fits over the flash ring, polarizing the fight reaching the subject, while the inner section again polarizes the light passing into the camera lens.
 |
T28 Macro Twin Flash 1 Two small but powerful separate flash heads mounted together on the front of the lens with the Macro Flash Shoe Ring and linked by cord to the T Power Control 1. The flash heads can be angled in any desired direction, assuring enormous versatility of lighting effects, from strong shadows to highlighted background, etc. The flash heads can be fired simultaneously or singly. They feature built-in modeling lamps, and can also take color or ND filters, etc. The Guide Number is 22 when both flash heads are used together, 28 when only one is fired (ISO 100, meters), In Manual they can be used at full or 1/4 power. |
Macro Flash Shoe Ring
An attachment unit that vastly increases the photographic range of the T28 Macro
Single Flash 1 and the T28 Macro Twin Flash 1. When attaches to the front of the
taking lens to provide a mount for the T28 Macro Single Flash 1 or T28 Macro Twin
Flash 1, allowing the flash heads to be angled in virtually any way for versatile
lighting effects. The electrical connection with the T Power Control 1 is made directly
from the flash head to the power unit socket. Both shoe mounts can be revolved freely
and locked at any position desired. With its double screw thread it can be screwed
into either 49mm ø or 55mm ø lenses. It cannot work with older manual
macro lenses 20mm/F3.5 and 38mm/F3.5.
T28 Macro Single Flash The T28 Macro Flash comes in two
versions. Both produce, unlike ring flashes, plastic lighting with shadows to emphasize
three dimensional shapes. Regardless of whether you prefer single or twin flash heads
arrangements, there have an option for you. The T28 Macro Single Flash
1 is an exceptionally small and light unit with a single flash head with a Guide
Number of 28m (100 ASA), which can be mounted on the T Power Control 1, or attached
to the front of the lens with the Macro Flash Shoe Ring. The T28 Macro Twin
Flash 1 has two flash heads which can be attached to the front of the lens
with the Macro Flash Ring, and can be used individually, with a Guide Number
of 28m (100 ASA), or simultaneously, with a Guide Number of 22m (100 ASA). The second
flash head of the T28 Macro Twin Flash 1 can be used as a fill flash to reduce shadows,
or to brighten the background. The effect of the second flash head can be changed
by bouncing or by using The filters of the T32 (diffuser, ND, colour filters) which
can be attached directly to the flash heads, and judged by operating the built in
modelling light. Main attaction os the macro flash is, the two TTL "OTF"
Auto flashes specially designed for close-up and macrophotography and the modelling
light (powered by 6V Power Pack 2 or AC Adapter 3) in the form of eight electric
bulbs are built into the flash heads to facilitate focusing and composition with
dark subjects, and to judge the plastic shadow effect. The flash heads can be bounced
70º upward, 45º down and 360º horizontally. When the T28 Macro Single
Flash 1 is mounted on the T Power Control 1, Normal Auto mode with three selectable
working apertures is available next to TTL "OTF"Auto and Manual operation
 |
 |
Angling up to 70° up, 45° down and 360° horizontally assures total versatility for a kind of subject. Though designed for macro work, his unit can be used for gener!al flash photography too. Its Wg power performance can be further enhanced by color and ND filters, while the built-in modeling lamp makes it particularly useful in night or low light photography. |

Olympus T8 Ring Flash 2 Olympus safely can claimed this is the only flash in the world that doesn't make you blink. It is essentially a TTL "OTF" Auto ring flash specially designed for close-up and macrophotography. The T8 Ring Flash 2 sends the flash output a way from the subject to be reflected indirectly onto the subject by a large or small reflector ring (Reflector 1 or Reflector 2). This flash unit works in tandem with the T Power Control 1 (containing 4 AA batteries, booster, capacitor, etc.). The effect is extremely soft, shadowless lighting which also eliminates the problem of ring-shaped images appearing on the subject in the picture. The Guide Number is a extremely diffused 8 in TTL Auto, switchable between 8 and 3.2 in Manual (ISO 100, meters). |
There were even two
reflectors. Generally , Reflector
1 is recommended with most subjects; Reflector 2 may be more suitable at extra close
working distances. The
200mm (Reflector 1) diameter reflector ring should
be used, but for extremely close or constricted working conditions the 150mm might
be preferable. It can also use the Power Pack 2 which can be used for both the flash
and the built-in modeling lamp. To optimize full potential of the OM Macro flash,
there are quite a number of system accessories that can help you to be more productive
and realize your creative vision of various photographic possibilities. Most of
these are essential components in a multi flash setup while retaining true TTL flash
metering. Of cause, you need not have to invest into all of these unless there
is an absolute necessity However, it is good to memorize some of these combinations
where it relates. Note: The T8
has two threads, and it can be screwed into either 49mm ø or 55mm ø
lenses. Most Zuiko micro lenses can be used without any compatibility problems, except
older manual macro lenses 20mm/F3.5 and 38mm/F3.5 and the newer Zuiko Macro 20mm/F2
lens which Olympus claimed is not recommended with the T8 Ring Flash.

Olympus TTL Auto Connectors Type 3 and Type 4 These units are screwed into the camera hot shoe socket when necessary, in place of the Accessory Shoe, providing full support for TTL "OTF" Flash in combination with a TTL Auto Cord T on the OM-2 or OM-2n. With the OM-1n and OM-2n, the signal for the flash ready / flash OK viewfinder LED is transmitted by TTL Auto Connector Type 4. Type 3 has the direct contact pin and flash coupling pin (see below).
 |
 |
 |
 |
 |
 |
The TTL Auto Connector Type 3 is designed exclusively for use with the OM-2 (without the "N" designation - it does not fit the OM-1, OM-1n or OM-2n) to accept a TTL Auto Cord T for off-camera flash operation. The TTL Auto Connector Type 4 is designed exclusively for use with the OM-1n or OM-2n (it does not fit the OM-1 or OM-2 series models) to accept a TTL Auto Cord T for off-camera flash operation. |
For OM1(n) it works only in Normal AUTO and manual flash as the flash coupling terminal does not function with an OM1n.
Auto Multi Connector/TTL Auto Connector T20 For simultaneous TTL Auto Flash with more than one unit, the Multi Connector provides linkage for three units via TTL Auto Cord T connections. It is very useful for creative control over lighting quality and adds dimension to lighting setup. Furthermore, additional flash units may be added using Auto Cords and Multi Connectors. Up to nine flash units may be used.
 |
 |
|
| The TTL Auto Connector T20 (Far Left) is needed to adapt the compact T20 flash unit to connect to a TTL Auto Cord. | ||
Simultaneous flash with up to 9 flash units (with 4 TTL Auto
Multi Connectors and 14 TTL Auto Cords T) can also be setup by using several multi-flash
connectors, the length of the TTL Auto Cords can be extended as long as 30m for TTL
Auto remote flash photography. Note: The maximum length of 30m also applies to a
multiple flash setup and should be watched when one or more cords are of length 5m.
 |
 |
 |
TTL Auto Cords: T 0.3m, 0.6M 2m, 5m To link the flash unit to the camera for off-camera use, or with Multi Flash photography, to link the flash unit to the TTL Auto Multi Connector, to the camera. These varying length cords all feature a special lock system to make accidental detachment impossible. These extension cords are required for off-camera flash operation, to connect a T-series flash unit to an OM camera. There are seven different types to meet every possible flash setup. |
TTL Auto Cord T 0.3m is intended for use with the Power Bounce Grip 2. TTL Auto Cord T 0.6m is a spiral type, extendable from 0.3m to 0.6m, also suitable for use with the Power Bounce Grip 2, or for instance a flash mounted on a long flash bracket. TTL Auto Shoe Cord T 0.6 is also a spiral type, extendable from 0.3m to 0.6m; one side has a Hot Shoe Mount instead of a plug, intended for cameras that don't have a (optional or built-in) TTL Auto Connector. TTL Auto Cord T 2m and TTL Auto Cord T 5m can be used to position the flash at longer distances from the camera, for instance tripod-mounted. TTL Auto Cord T2 0.1m has two plugs that make a 90º angle with the cord; connects the T45 flash to the built-in TTL Auto Connector of the OM-Sp, OM-3(Ti) or OM-4(Ti); this cord uses less space, because there are no protruding parts. TTL Auto Cord T2 0.15m is intended for use with the T45 and a Motor Drive.
M.
Grip Cord/M. Grip Cord 2 When the
camera is used with the motor drive or winder and the T45 flash unit, a special release
on the grip allows easy and smooth motorized flash photography. The M. Grip Cord
is used in this case to link the grip shutter release to the motor drive or winder.
 |
AC Adapter 2 A compact and economical adapter unit that allows the T32 and T20 electronic flash units to be powered by regular AC household current. The advantage is a constant faster recycling times and a more cost efficient method for studio and other indoor work. The shown version is version 2, as there are a few earlier and latest unit, check below for compatibility with various OM units. |
The F.AC Adapter (1)
is used with the Quick Auto 310 flash or Bounce Grip and cannot
be used with a T series flash or the Power Bounce Grip 2. The F.AC Adapter
2 is used with the T20, T32, T45, T Power Control 1 or Power Bounce Grip
2; cannot be used with the Quick Auto 310. The F.AC
Adapter 3 is used with the T20, T32, T45, T Power Control 1 or Power Bounce
Grip 2, and can also power the Winders and the modelling lights of the various Macro
Flashes; cannot be used with the Quick Auto 310. i.e. With the Quick Auto 310, use the F.AC Adapter.
With a T-series flash, use either F.AC Adapter 2 or F.AC Adapter 3. While most of the system accessories
still provide some level of fore-and backward compatibility. Standard accessories
such as creative filter set, Zoom head extender and height extender can still be
used, mainly because flash model such as the evergreen T32 virtually remains unchanged
since its inception a few decades ago.
