Safety
Precautions
1.Do not
stare at the sun or a bright light source through the
lens with the Extender attached,or with a camera with the
Extender and lens attached.Doing so could result in
visual impairment.In particular,do not look at the sun
directly through the lens with the Extender
attached,otherwise it could result in loss of
vision.
2.Do not
leave the lens with the Extender attached,or a camera
with the Extender and lens attached in the sun without
the lens cap on.Otherwise it may result in concentrating
the suns rays ,causing a fire.
3.Do not
leave the Extender in excessive heat places, such as in a
car with direct sunlight.High temperatures can cause the
Extender to malfunction.
Using an
Extender with this lens may result in incorrect
autofocus.
If your
camera has an AF microadjustment function,do the
AFmicroadjustment.
If your
camera does not have an AF microadjustment
function,focusmanually if the AF precision is way
off.
If the
automatic focusing does not smooth,it is because the lens
aperture is too small and zoom out two stop of the
aperture to decrease half of the into light.At that
time
please focus
manually if the AF is not smooth
Mounting and
dismounting the Extender
First attach
the Extender to the lens,then attach it to the
camera.Please follow the opposite procedures to
disassemble.
To detach the
Extender from the lens,push the lens release lever as
shown by the arrow,then turn the Extender
counterclockwise.
Maximum
Aperture with the Extender
When Extender
EF2X is attached,the lens maximum aperture will be
smaller by 2 stop.In the above two case, the camera will
compensate the exposure automatically.
Caution
Do not attach
two or more Extenders on the same camera.Doing so will
degrade the optical performance and the camera will not
be able to obtain proper exposure readings.
In order to
maintain the precision of autofocus control,the speed of
automatic focusing will slow down when using the
Extender.
When the lens
taken from cold to warm places, the surface and internal
condensation may occur. In order to prevent condensation,
when taking the lens from cold to warm places, please
first put the lens in sealed plastic bags, then take out
after the lens warming up. And use the same method when
taking out from the warm to cold places.
