Selecting the right lens is critical when purchasing a digital camera. Basically, lenses can be categorized this way: fixed focal length, retractable zoom, fixed zoom and interchangeable lenses.
Fixed focal length lenses are the cheapest and simplest to use. Designed for those on a very tight budget, children or real novices, fixed focal length lenses typically offer only a wide angle view, which can be perfect for landscapes and group photos. The quality of the pictures taken using this lense, however, is not that great. Fixed focal length lenses can’t zoom in distant objects and they don’t accept converters. An autofocus lens, with a selectable macro or landscape focus mode, is often a better selection.
Retractable zoom lenses extend whenever the camera is turned on and retract when it is shut off. This type of lens is reasonably priced and takes decent pictures. A retractable zoom lens gives you a very compact digital camera style while fully protecting the lens. It offers a limited zoom range that magnifies two to three times. Retractable zoom lenses do not support filters or converters and slightly delay the start-up time of the digital camera. They also have limited manual focus controls.
A fixed zoom lens will accept converters, filters and flash rings. These extra features will allow an experienced photographer the ability to take beautiful close-ups, wide-angle and telephoto photography. A fixed zoom lens allows a magnification of up to 12x. Fixed zoom lenses offer advanced and precise zoom and manual focus controls through rings on the lens instead of buttons. This type of lens might be a bit complicated for a novice and it might be a bit bulky to be convenient.
A serious amateur or professional will use a digital SLR with interchangeable lenses. These fully detach from the camera and are replaced with a different lens. If you already own lenses for a traditional film camera, you can usually find a digital camera with a compatible SLR body. A digital SLR is the most flexible lens for all shooting situations. An added advantage is that if you want to upgrade your lenses, you can do so without buying a new camera.
Of course, the lenses can be quite expensive. They can also be quite heavy and inconvenient to carry. If you are not very knowledgeable about camera lenses, the options may be confusing and if you understood your lenses on a traditional film camera, you may be confounded by the focal length on the digital. The learning curve is a bit steep and long, but the picture quality makes it well worth it!
