The T10 Ring Flash 1 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.	A TTL "OTF" Auto ring flash specially designed for close-up and macrophotography. Compact and functional, it is ideally suited for medical, scientific and outdoor action photography. Guide number is 10m (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. With the aid of the optional Ring Cross Filter POL, existing of an outer polarizing filter (covering 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 (shells, human eyes, etc.).	This flash unit 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. Ring flashes may cause red-eye effect in portraits.
