Wide-angle lenses are used in photography to capture architecture, landscapes and interiors. Such cameras are distinguished by a large depth of field, due to which images are obtained that are simultaneously focused on near and far objects. This feature allows you to shoot high-quality panoramas and cover the entire view of the attraction.
Instructions
Step 1
Look for cameras that have a focal length of 24 to 40mm if you are interested in wide-angle lenses. The indicator less than 24 mm refers to ultra-wide angle, but their cost will be slightly higher.
Step 2
When choosing such cameras, it is also necessary to take into account such a parameter as perspective. It characterizes the relative length and size of objects in the frame. Wide-angle lenses are distinguished by the fact that objects appear large in the foreground and distant in the background. To prevent this effect from being too harsh, you need to select the camera based on how far you are going to stand from your subjects.
Step 3
Determine what type of focal length you need to shoot. Fixed focal length or Fix lenses have a high aperture ratio and an affordable price. They are not able to zoom in or out on selected objects. Variable focal length or Zoom lenses differ in that they can zoom in and out of objects in the frame, which is much more convenient to use. However, their disadvantage is that they do not always allow you to take high-quality pictures. While fixes are lighter and more compact, they are designed specifically for a specific type of photography. In this regard, it is advisable to purchase for a wide-angle lens not only a universal Zoom, but also several types of Fix.
Step 4
Find in the characteristics of a wide-angle lens such a parameter as aperture. It is usually denoted "f / number". If it says “f: number-number”, it means that the lens has a range of focal lengths. In this case, the first number is responsible for the aperture ratio at the short end, and the second - at the long end. The aperture parameter is responsible for the ability of the camera to shoot in low light conditions. The lower the specified number, the higher this parameter. However, for wide-angle lenses, a large aperture is not needed, since in most cases it will have to be reduced. For example, if you chose a wide-angle zoom lens, the ideal aperture would be “f: 2, 8-4, 0”.
