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.
