How to Use a Zoom Lens I have recently purchased a Nikon f-55 with 28-80mm 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 do not 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.

The 3 markings, 28, 50 and 80 are the zoom range. You can turn to any setting you want (or in between). Then you press the shutter half way down to set the focus. What the manual says is that every time you change the zoom range, you have to press the shutter down half way to re-focus. When the camera is focusing, do not turn the zoom range. In manual focus mode, you first set the desire zoom range, then there should be another ring to turn to set the focus or turning the front lens element to set the focus, depending on the type of lens you have. Hope this helps.

you can use any mm for 28-80 it doesnt have to be set on any perticular number. everytime you move further or closer to the subject you need to adjust your focus. try just doing it manually for a while, but remember auto focus doesnt work great in low lightning situations with out some kinda flash, sync
