Discover How To Save Money When Shopping For Camera Lenses.
Looking for a camera lens, but you are not sure whether the more expensive lens is better than the heavier lens? Confused by all the stats? Discover how the perfect lens could be sitting right in front of you. There are many different functions that they perform and knowing what they do will make purchasing camera lenses easier than ever before.
There are varying lens elements to consider, what a lens element does is it will bend the light to reflect the image in as much exacting details as it can upon the digital sensor. Optical oddities can come to pass when the light is not depicted accurately on the sensor. Vignettes, blurring, distortions, reduction in contrast and misalignment of colors may be present.
Another important thing to consider is the focal length of the lens. It establishes the angle of view as well as how subjects are magnified. If you would like your image to have a stretched or exaggerated perspective you will want a small focal length and would use a wide angled lens. If you would like your image to have a flattened or compressed perspective you would want a larger focal length you would use a telephoto lens. Where the photographer and camera is in relation to the photograph is the perspective.
Focal length can be a very useful tool in photography, so this can be an important feature you may wish to have. Other factors may influence your decision as well, telephoto lenses are more susceptible to camera shake, small hand movements may become magnified in the image. As well they require shorter exposure times in an attempt to minimize the blurring. Wider focal length lenses tend to be more resistant to flare.
Many advantages can be gained from zoom lenses, you can attain alternate perspectives of the same subject without replacing the lens with a new one. Also you do not have to crop the image to change the composition. With two different types of zoom it can be confusing as to which one is better for what you require it for. Optical zoom is when the light is increased before it reaches the sensors, where as the digital zoom is altered, also called interpolated, after the light has already reached the sensors.
A prime lens is similar to the zoom lens, but has its own advantages and draw backs. They do not allow changes of composition unless you are willing to crop the image. They tend to weigh less than zoom lenses, they are faster and are cheaper. A modestly priced prime lens will perform just as well as a good quality zoom lens, if not better in terms of image quality. They tend to offer better light intake than fast zoom lenses, something you would find important for low light projects.
Aperture is a very important feature, something you will have to keep in mind as well when making your decisions. It is the measurement in which the lens opens and closes to allow light in. It is listed as a f-numbers to define their ability to take in light. The faster is is the lower the f-number will be.
This can be quite confusing, when the f-number is higher the aperture size is smaller, the required shutter speed is slower and the depth of field is wider. Conversely when the f-number is lower the aperture size is larger, the required shutter speed is faster and the depth of field is narrower.
