ELECTRONIC FLASH WIDE ADAPTER • ND FILTER SET T32

This set of 3 filters (a wide-angle diffuser and two neutral density filters) are designed specially for use with the Electronic Flash T32. The Wide Adapter increases the T32’s angle of coverage to the picture area of a 21mm super wide-angle lens, and also provides a softer, more natural illumination. The ND filter reduces the quantity of flash light without affecting color quality.

(1) Turn the T32’s diffuser window fully upward (90°).

(2) Fit the filter into two grooves (dovetail)

(3) until it stops with a click.

• Cautions

1. These units cannot be used with any electronic flash other than the T32.
2. When attaching to the T32, hold the filter firmly in place; otherwise it will slip off when the diffuser window is turned to 0° position.
3. Clean the filter with a soft, dry cloth. Do not use organic solvents (alcohol, thinner, etc.).
4. In Manual flash mode
