● Because the EOS D30 has a smaller sensor area than
that of a 35mm-format camera, the angle of view of all
EF lenses is changed. The effective focal length of all
lenses is increased by a factor of 1.6, eg a 50mm lens
has approximately the same angle of view as an 80mm
lens.
● AF stands for autofocus.
● MF or M stands for manual focus.
● Be careful not to lose the lens caps or body cap.
