Using a Zoom Lens
Use the zoom ring to zoom in on the subject so that it fills a
larger area of the frame, or zoom out to increase the area
visible in the final photograph (select longer focal lengths
on the lens focal length scale to zoom in, shorter focal
lengths to zoom out).
Note that in the case of the AF-S DX NIKKOR 18–55mm
f/3.5–5.6G VR, changes to zoom can alter maximum
aperture by up to 1
1 /
3
EV. The camera however
automatically takes this into account when setting
exposure, and no modifications to camera settings are
required following adjustments to zoom.
