There are dozens of lens attachments available for your SLR camera.
Film and digital SLR cameras possess the capability of switching out the main lens for another. This is useful, as you may occasionally need a wide-angle, telephoto or zoom lens. An 18-105mm is a zoom lens that helps you move closer to a subject matter, without actually walking up to it. The 18-105mm lens functions much like your standard lens, so you shouldn't have too much trouble learning the basics of the equipment.
Instructions
1. Remove the current lens from your SLR camera if you haven't already. Press and hold down on the button located right next to the lens on the camera. This unlocks the lens. Twist the lens counterclockwise to remove the lens.
2. Align the small dot on the end of the 18-105mm lens with the dot on the top of the opening of your SLR camera. With the two dots matching, slide the lens into the camera and turn it to the right. This locks the lens into position.
3. Twist the lens to zoom in (clockwise while you are looking through the viewfinder). As you zoom in, the subject matter in the viewfinder becomes larger. To zoom out, twist the lens in the opposite direction.
4. Adjust the switch on the side of the lens to either "Auto Focus" or "Manual Focus." With the auto focus feature turned on, the camera adjusts the focus for you. To manually focus on a subject, zoom the lens completely into the object. With the camera zoomed in, turn the focus ring on the lens until the object is clear and in focus. Once focus is set, zoom out of the subject until you have the desired framing and capture your image.
