The Canon EF17

~40mm

f/4L USM is a high-

performance wide-angle zoom lens.

"USM" stands for Ultrasonic Motor.

Features

1. Two aspherical elements and a Super UD

element result in sharp pictures and

outstanding image delineation.

2. Ultrasonic Motor (USM) for silent and high-

speed AF operation.

3. Manual focusing enabled even in the AF mode.

4. Circular diaphragm for better background blur.

5. Sealed construction for higher dust- and water-

resistance compared to previous lenses. (For

maximum protection, a filter must also be

attached to the front of the lens.)

Handling Cautions

If the lens is taken from a cold environment into a

warm one, condensation may develop on the lens

surface and internal parts. To prevent condensation in

this case, lirst put the lens into an airtight plastic bag

before taking it from a cold to warm environment.

Then take out the lens after it has warmed gradually.

Do the same when taking the .Iens from a warm

environment into a cold one.

Although the lens is dust- and water-resistant, a filter

must also be attached to the front of the lens for

complete protection. (The front of the lens moves

during zooming.)
