Attaching and Detaching a Lens

To owners of the EF-S18-200mm f/3.5-5.6 IS lens:

You can prevent the lens from extending out while you are carrying it around. Set the zoom ring to the 18mm wide-angle end, then slide the zoom ring lock lever to <LOCK>. The zoom ring can be locked only at the wide-angle end.

Do not look at the sun directly through any lens. Doing so may cause loss of vision.

If the front part (focusing ring) of the lens rotates during autofocusing, do not touch the rotating part.

Image Conversion Factor

Since the image sensor size is smaller than the 35mm film format, it will look like the lens focal length is increased by 1.6x.
