You can adjust the 'zoom' ring in either auto or manual mode to crop
the scene through your viewfinder as per your compositional likings. In
autofocus mode, the 'focus' ring locks and you are not supposed to move it.
I am a canon user; in good Canon lenses, you can manually change (tweak)
the focus in both auto and manual focus mode.

Subject: how to use zoom lens-nikon
f55
I have recently purchased a nikon f-55 with 28-80
mm lens.Please guide me about the following :
the lens has 3 markings on it 28mm,50 mm & 80
mm. When I use manual focus I can rotate the lens as per my choice.but when I
use auto focus am I supposed to keep the lens at 50 mm marking always or I can
use all the 3 markings on the lens i.e. 28 mm as well as 80 mm. I am in doubt
as the manual says in auto focus don't move the lens.But does it mean donot
move from any of the 3 markings or keep at 50 mm only.?
I know it is very stupid of me to ask such naive
questions.But frankly I am a novice in the field of auto focus.Please
help.
