Structure

Waterproof (up to 5m for 10 minutes) and nitrogen-filled

Waterproof mode:

The EDG is waterproof, and will suffer no damage to the optical system if

submerged or dropped in water to a maximum depth of 5 meters for up to 10

minutes.

The EDG offers the following advantages:

• Can be used in conditions of high humidity, dust and rain without risk of

damage.

• Nitrogen-filled design makes it resistant to condensation and mold.

Observe the following when using the EDG.

• This unit should not be operated nor held in running water.

• Any moisture should be wiped off before adjusting movable parts (focusing

knob, etc.) of the EDG to prevent damage and for safety reasons.

To keep your EDG in excellent condition, Nikon Vision recommends regular

servicing by an authorized dealer.
