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,rst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lensfromawarmenvironment
into a cold one.
● Do not leave the lens in excessive heat such as in a
car in direct sunlight. High temperatures can cause
the lens to malfunction.
Usage Precautions
● Whenusingthislens,pleasechecktheCanonwebsite
forthelatestcamerarmware.Ifthecamera’srmware
isnotthelatestversion,besuretoupdatetothelatest
rmware.
● Fordetailsonupdatingrmware,pleasecheckthe
Canonwebsite.
Safety Precautions
● Do not look at the sun or a bright light source
through the lens or camera. Doing so could result in
lossofvision.Lookingatthesundirectlythroughthe
lens is especially hazardous.
● Whether it is attached to the camera or not, do
not leave the lens under the sun without the
lens cap attached. This is to prevent the lens from
concentratingthesun’srays,whichcouldcauseare.

cameraisOFFduetotheuseoftheautopowerofffunction*1,thelensperformsaninitialresetofthefocuslens.*2
● Althoughtheimageintheviewnderwillappearoutoffocusduringtheinitialreset,thisdoesnotmeanthatthe
lens has malfunctioned.
● Althoughtheshuttercanbereleasedduringtheinitialreset,usersmustwaitapproximately1second*3after the
initial reset has completed before shooting.

EOSREBELT5i/700D,EOSREBELSL1/100D,EOSREBELT4i/650D
*2: Withsomecameras,thelensmayperformaninitialresetinordertoimprovelensperformanceevenattimes
other than described in this section.
*3: The initial reset time varies depending on camera being used.
When using the lens with lm-based SLR cameras
● Thedrivespeedofthefocuslenswillbeslowerthanwhenthelensisusedwithadigitalcamera.
● Imageswillappearoutoffocuswhenusingthecamera’sinternalashwhileitischargingorwhenzooming
during exposure for still images.
