A guide to the types of camera lenses

camera lens


Different types of camera lenses are suitable for different activities. You need a telephoto lens to capture pictures from a long distance? How about a macro lens for close-up photography? Familiarize yourself with the camera lens popular so you can determine which are best for your application photo.

Wide

Wide-viewing angle lenses are ideal for shooting interiors, landscapes and large gatherings. The importantthing to look at when shopping for the angle of the camera objectives at European level is the consistent quality of the shot. If you're watching a wide-angle lens with a clear center crystal and blur the edges, keep on looking. You may also experience spherical aberration, or distortion wide-angle images. If you can not afford a quality wide-angle lens to avoid these effects, hold off making a purchase and save your money until you are able to achieve the goal of quality isneed.

Telephoto

telephoto camera lenses may be the most difficult type of camera lens to buy. Telephoto lenses are generally more expensive, as the quality of the glass makes a big difference in long-haul applications. Typical uses for telephoto lenses are sporting events, features of the landscape and animals in nature. The longer the telephoto lens, the larger the aperture goes, and then look for a length proportionalopening width when shopping for lenses telephoto. Because most require more than glass lenses, long lenses are significantly more expensive than shorter lenses.

Zoom

Unlike a fixed focal length lens, a zoom lens that offers the possibility of recovery is subject near and far. Zoom camera lenses suffer a slight loss of quality compared to fixed length, but slow to compensate for the difference in quality for their usefulness indifferent applications. If you're looking to run fast the subjects at different distances, as a moving object, you can not have the time to change lenses with a fixed length as the subject comes close to you or away. Zoom lenses offer the ability to keep a moving subject in frame and are good choices if you need a versatile lens for moving subjects, or a variety of applications.

Standard

While the camera lens may seem superfluous in standardlight of specific objectives for different applications, in fact, the opposite is true. Standard lenses require more thought the shot and you're planning to move to get a good angle and distance, but take great photos and the process helps you learn to write better shots. A photographer can use an advanced standard good target for a variety of applications, where a novice photographer can feel the need for any special lensesapplication.

Macro

A macro lens of the camera is designed for very short-range close-up photography. Macro lenses are not good at capturing close-ups from afar, like a telephoto lens, but are designed for photographers to be close to the subject. Macro lenses are ideal for nature photography, photography and science photography collectors.

Digital Photography - How to choose the perfect lens

camera lens


If you decide to buy a digital camera you should give some thought to the lens you need. The best way to do this is to think of what will be mostly using the camera. Two key factors affecting this decision is the type of objects that will be taken and the amount of time you will have to take the picture. When shopping for a new digital camera you will see 2 letters on the camera lens zoom buttoncontrol. These two letters are the T stands for telephoto and the second is letter W stands for wide angle. To understand more about what these mean to read the brief descriptions that follow on these two characteristics of the lenses:

Telephoto

The telephoto lens is the lens that you see commonly used by sports photographers and paparazzi. The telephoto lens has different focal lengths that allow you to close in on a specific object orsubject to long distances. The telephoto lens works by compressing more areas around the subject you are taking a picture. This translates into an image that has more features and a soft out of focus or blurred background.

Wide

The situation is better to use the wide angle is when you want to get a panoramic view. This includes shots of landscapes, large and long buildings. For example, taking a picture of a football field long, you can use the functionality of a wide-angleas it would be able to take the entire length of the pitch.
The wide-angle shots are not limited only to take panoramic photographs horizontal may also be used for vertical shooting. These are situations where the subject is very high in terms of size, for example, the tall wooden door is the entrance to a cathedral or a shot of the Eiffel Tower in Paris was taken with a wide angle shot. In this way, the focus will be on the central object, rather than the surrounding area. With thesetypes of strokes, it is recommended to use a tripod to help them make a constant tension and to ensure the camera remains stable.
