Technique tips: Characteristics of long lenses

Compared to a normal focal length lens, a long focus or a telephoto lens:

1. Has greater magnification, a narrower field of view, less depth of field, and a smaller maximum aperture.

2. Weights more and is physically longer.

3. Produces more noticeable image blurring from the same degree of vibration or camera shake during exposure.

4. Requires a deeper lens shade for maximum avoidance of flare.

5. Is more likely to cause a slight bluishness in color images, and therefore to require a skylight filter.
