Flashphoto Group T28 Macro Single Flash 1 / T28 Macro Twin Flash 1
|Summary||Main Characteristics||Notes - Related Units|
|The T28 Macro Flash comes in two versions. Both produce, unlike ring
flashes, plastic lighting with shadows to emphasize three dimensional shapes.
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 a T32 filter, and judged by operating the built in modelling light.
|Two TTL "OTF" Auto flashes specially designed for close-up and
Plastic lighting effect is obtained because of the position of the flash head(s) next to the front lens.
Guide number is 28m (100 ASA) at peak with one flash head (Single Flash or Twin Flash) or 22m (100 ASA) at peak with two flash heads (Twin Flash).
A modelling light 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.
|These flash units works in tandem with the T Power Control 1 (containing
4 AA batteries, booster, capacitor, etc.).
Having two threads, the Macro Flash Shoe Ring 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 filters of the T32 (diffuser, ND, colour filters) can be attached to the flash heads.
