T8

Summary	Main Characteristics	Notes - Related Units
The T8 Ring Flash 2 screws into the front of the camera lens and links with the T Power Control 1 mounted to the camera, to provide shadowless lighting at extremely close camera distances. Ring flashes are especially intended for macro lenses. The unique concept of this ring flash unit is to provide soft, indirect lighting for close-up subjects. The flash is bounced off Reflector 1 or Reflector 2 to reach the subject indirectly. This makes possible completely shadowless lighting for any subject smaller than the reflector. It completely solves the problem of ring shaped reflections.	A TTL "OTF" Auto ring flash specially designed for close-up and macrophotography. Guide number is 8m (100 ASA) at peak. A modelling light in the form of eight electric bulbs are built into the flash surface to facilitate focusing and composition with dark subjects.	This flash unit works in tandem with the T Power Control 1 (containing 4 AA batteries, booster, capacitor, etc.). Having two threads, the T8 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 Zuiko Macro 20mm/F2 lens is not recommended with the T8 Ring Flash. The modelling light is powered by the 6V Power Pack 2 or AC Adapter 3. Reflector 1 is recommended with most subjects; Reflector 2 may be more suitable at extra close working distances.
