Trying to find the right camera lens for your projects can be tough, but it does not have to be. There are some things that you should be aware about when searching for the right lens. There are many different kinds of camera lenses that perform in different ways. Each one can be a tricky balance between size, weight, cost, lens speed and image quality.
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.
Lens focal length plays an important role in the image as well, it determines the angle of view and how an object will be magnified. A wide angle will have a small focal length and stretches or exaggerates the perspective while a telephoto lens will have a larger focal length and compresses or flattens the perspective. Perspective is where the photographer is in relation to the image being captured on film, that being said some believe that the focal length changes the perspective.
One thing you will wish to consider that may alter your choices is how susceptible and resistant are the features. Telephoto lenses tend to be very sensitive to unsteady hands, the smallest movements can cause cataclysmic results to your photographs as they would be magnified. In order to combat this, they need shorter exposure times to reduce the blurring. A wide focal length lens seem to be more impervious to flares from light sources.
The zoom lenses on a camera has many advantages, you can achieve many different perspectives of the same image without changing the lens. Zoom lenses allow you to change the composition without cropping the image. There are two types of zoom, digital zoom and optical zoom. Optical zoom is where the magnification of light is increased before it reaches the digital sensor. Digital zoom is where the image is interpolated (bent and distorted) after it has been acquired at the digital sensor.
Another lens is the prime lens, they have many advantages as well as disadvantages. You cannot change the composition of an image unless you crop it. They weigh less, and are faster than zoom lenses as well as easier on the wallet. An affordable prime lens is equivalently comparable, if not better than, in terms of image quality as a fair quality zoom lens. A good prime lens provides better light acquiring than a rapid zoom lens, something you have to consider for low light.
The aperture is an extremely important feature for a camera and something you will probably wish to consider as well. Aperture is the measure in which the lens opens up or closes at to allow in more or less light. They are listed as f-numbers to characterize how well they gather light. The lower the f-number the larger the aperture, and the faster they are.
Understandably so, this is often a bewildering area. When the f-number is lower, aperture size is larger, the required shutter speed is faster also the depth of field is narrower. Contrarily when the f-number is higher, aperture size is smaller, the required shutter speed is slower also the depth of field is wider.
