When using the lens with lm single-lens reex camera
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 while the camera’s internal ash is charging or when zooming during
exposure for still images.
Even when the camera in <ON>, images may appear out of focus when zooming. If this occurs, press the
shutter button halfway while zooming.
After focusing in AF mode or AF operation in the ONE SHOT AF mode and zooming by holding the shutter
button halfway, the camera may indicate that the AF mode has been changed to manual focus (MF) mode.
During continuous shooting, zooming may slow down shooting speed.
There are some cases when users must wait a few seconds after zooming before the autofocus (AF) will
function.
When using the lens with lm single-lens reex camera other than the EOS-1V/HS, information may not be
displayed on the lens information display (p.13-17) even when pressing the shutter button down halfway or all
the way, or when pressing the display mode select button.
When using the lens with certain lm single-lens reex cameras, displaying information on the lens
information display may cause the autofocus (AF) to stop working. In this case, please shoot after rst setting
lens information display to OFF (p.13).
