How to Choose a Camera Zoom Lens

While many digital cameras offer built-in zoom lenses, higher-end models still have removable, external lens options, allowing for extreme variation, and giving unlimited zoom options based on attachments and accessories. When choosing a new camera lens, it's best to get one with features complimentary to your intended use. Every camera will have different lens options available, so the type of lenses offered for your specific camera needs to be factored in your final choice. Generally speaking, reputable camera companies will have a wide range of lens options, making it easy for you to find just the right one for your needs.

Instructions

1. Determine whether you need a fixed view or varifocal lens. Most amateur photographers will prefer the more noticeable functionality of a variofocal lens when compared to the more subtle functionality of fixed view lenses. Fixed view lenses cannot be adjusted for wider or narrower angles, but they do allow for intricate focusing capability. Varifocal lenses allow for adjustments between panoramic and narrow views.

2. Select the best imager option. A larger imager means a larger field of view, which is optimal for most photographers. Common sizes are 1/4 inch and 1/3 inch, with 1/3 being best for most casual photographic enthusiasts.

3. Look for a camera with Pan-Tilt-Zoom options as needed, also known as PTZ capabilities. Most photographers will want simple zoom capabilities, but may not need electronic pan and tilt features. Discern whether or not these features are worth the extra money they may cost.

4. Consider light filtering options. If you're going to be doing a lot of bright, outdoor shooting, an automatic iris filter may be necessary---for most photographers, standard filtering will work fine.

5. Choose the best size lens for your camera and your usage. A standard focal length is about 40 mm to 50 mm. For close-ups, seek a lens larger than 50 mm. For wide-angled shots, choose a lens smaller than 40 mm.
