Instruction

Conventions used in this instruction
The Canon EF16-35mm f/2.8L II USM lens is a high-performance, ultra-wide-angle zoom lens for use with Canon EOS cameras.
"USM" stands for Ultrasonic Motor.

Thank you for purchasing a Canon product.

Features

1. Aspherical and UD lens elements result in outstanding image delineation.

2. Ultrasonic motor (USM) for quick and quiet autofocusing.

3. Manual focusing is available after the subject

comes into focus in autofocus mode (ONE COPYSHOT AF).

4. A truly round aperture hole results in a nicer background blur.

5. Tight seal structure ensures excellent dustproof and drip-proof performance.

• Since the front element of this lens moves when zooming, you need to attach a Canon PROTECT filter sold separately for adequate dust-and water-resistant performance. Without a filter, the lens is not dust or water resistant.

Warning to prevent lens or camera malfunction or damage.

Supplementary notes on using the lens and taking pictures.
