Olympus OM Equipment for Close-up and Macro PhotographyT28 Macro Single Flash 1IntroductionThe T28 Macro Single Flash 1 is one of 4 macro flash units for the Olympus OM cameras that use the T Power Control 1 and provide automatic exposure using the camera’s TTL flash control, so that you do not need to calculate the additional exposure required by magnification. The flash head can attached to the plug for the Power Control or to the Macro Flash Shoe Ring that fits the filter mount of most of the Zuiko macro lenses. When used with the Olympus OM-2, OM-2N, OM-2SP, OM-3, OM-3Ti, OM-4 or OM-4Ti cameras, automatic exposure using the camera’s TTL flash control is possible. Other cameras can also be used, but the exposure would need to be determined using a flash meter, trial and error, or the appropriate stick-on label for the Calculator Panels. First screw the Shoe Ring onto the macro lens, and then attach the flash head by sliding it into one of the shoes on the Ring. The head locks into place using a groove in the base of the foot. To remove the head, push the button on the front face of the shoe in the direction of the white arrow, and then slide out the head. To attach the plug to the Power Control, align the red dots on the plug and the Power Control, insert the plug, and turn it clockwise until it clicks and locks into place. To disconnent the plug, press and hold the small black button on the front of the Power Control, turn the plug anti-clockwise until the red dots are aligned, and then release the button and withdraw the plug. When fitted to the Shoe Ring, the flash head can point directly forwards, or it can be tilted inwards through about 65° to aim it at the subject, or it can be tilted outwards through about 45°; there are click stops at 7 positions. The flash head can also be rotated through 360°, with click stops at 45° intervals (rotation is restricted to 45° when tilted inwards at 65°). The shoes can be moved around the Ring when the 2 black buttons on either side are held in; releasing the buttons locks the shoes in place. When fitted to the Power Control plug, the flash head can point directly forwards, or it can be tilted downwards through about 45° to aim it at the subject, or it can be tilted upwards through about 65°; there are click stops at 7 positions. The flash head can also be rotated through 360°, with click stops at 45° intervals (rotation is restricted to 45° when tilted downwards at 45°). The accessory foot on the head has a ¼ inch socket in its base that allows the head to be attached to a lighting stand or a tripod.
Rear of Olympus OM T28 Macro Twin Flash 1 The flash head contains small bulbs that act as modelling lights and can be useful for focusing in dim light and to preview the lighting and any reflections. The modelling lights are much less bright than the flash, and so they do not need to be turned off when a photograph is taken. The socket at the rear of the head for powering the modelling lights is a standard 2.1 mm DC power socket. Power for the modelling lights can be provided from either the 6V Power Pack 2 or the AC Adapter 3. A ring around the power socket can be turned to switch the modelling lights on and off. By reversing the Calculator Panel at the rear of the T Power Control 1, manual flash is possible, with a choice of 2 apertures.
VersionsOnly one version is known. AccessoriesThe T Power Control 1 is essential – the Macro Flash cannot be used without it. The Macro Flash Shoe Ring can be used to attach the flash head to the 49mm or 55mm filter mount of a lens. The diffuser and filters in the ND Filter Set T32 can be used to reduce the light output of the flash head. The modelling lights can be powered by either the AC Adapter 3 or the 6V Power Pack 2. A Calculator Panel for use with 50mm lenses was supplied. Self-adhesive labels were provided with the T Power Control 1 to stick onto a Calculator Panel to provide readings for manual flash with the Zuiko Auto-Macro 20mm f/2, Zuiko Auto-Macro 38mm f/2.8, Zuiko Auto-Macro 80mm f/4, Zuiko Auto-Macro 135mm f/4.5 and 50mm lenses (including the Zuiko Auto-Macro 50mm f/3.5).
