The UFL-2 is an external flash specifically for underwater use, featuring the new "RC data transfer" wireless communication method developed originally by Olympus. When connected (via an optional fiberoptic cable) to the PT-E05/E-520, the UFL-2 can easily be set up and controlled via the LCD panel on the back of the camera, making it easy to quickly respond to a variety of fast-changing underwater shooting situations. The UFL-2 is also compatible with slave auto firing so that it can be used with other digital cameras (those in firing modes without pre-firing, such as the slave mode or manual firing mode).

Has all functions of the FL36-R:

• RC Mode
• Guide No. 32
• Color temperature 5600K
• TTL underwater flash function triggered by fiber optic cable or Olympus TTL cable.
• Exposure control: Manual and TTL setting possible
