When Using A Telephoto Lens
Not Just About Getting Up Close
Apart from the obvious use of photographing subjects that are far away, a telephoto lens can also be used for effect. The higher the focal length, the more compressed the field will become. This basically means that the background will appear to be closer to your subject, the more you zoom in. This can be used to flatten backgrounds that are otherwise too crowded, or to simply make a subject in the background seem closer.
Emphasise the Subject
Even if the aperture is the same, a longer focal length will result in a more blurred background. You can use this to your advantage. Even if you don’t have an expensive f/2.8 lens or a fast prime, you can blur out the background by zooming in to the maximum focal length possible.
Be Careful About Focusing
Since the DOF at the telephoto end is very shallow, focus can be very critical. Even the slightest of mistakes may look bad. Use the Single Point AF function if possible and if the subject is moving around very quickly, you may want to fire a number of shots.
