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.)
