1/500 to 1/1000 on a fine day when the ISO sensitivity is set to
400. If you're using a digital single-lens reflex camera, take your
photos while checking each image on the LCD monitor:
●
The image is too dark: Lower the shutter speed.
●
The image is too bright: Raise the shutter speed.
Set the shooting mode to “M (manual).” On the

If this lens is used with a Canon EOS series camera, the following
operations may be required on some models due to the mecha-
nism of the camera:

is attached:
Open up the aperture (adjust it to the smallest value).
