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 α77 and certain
other models, the non-lens release lock function must be
canceled.

If this lens is used with a Canon EOS series camera, the following

nism of the camera:

No action is needed in this regard.
• A value (e.g., F5 or 6) is displayed as an aperture when the lens
is attached:
Open up the aperture (adjust it to the smallest value).
