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.
Image sensor size
(22.3 x 14.9 mm / 0.88 x 0.59 in.)
35mm image size
(36 x 24 mm / 1.42 x 0.94 in.)
