How Do I Choose the Best Wide Angle Telephoto Lens?

A wide-angle lens is a photographic lens with a focal length shorter than a standard lens, a viewing angle greater than a standard lens, a focal length longer than a fisheye lens, and a viewing angle smaller than a fisheye lens. Wide-angle lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses.

Wide-angle lens

Wide-angle lenses are widely used for shooting large-scale landscape photography. It can increase the sense of space depth of the shooting picture; The depth of field is longer, which can ensure that the front and back scenes of the subject can be clearly reproduced on the picture. Therefore, most of the modern compact automatic cameras (commonly known as point-and-shoot cameras) use a common wide-angle lens of 38-35 mm; the lens covers a large area and the range of scenes is wide; The image of the scene taken by the lens is small in the frame; in the frame, perspective distortion and

1, the wide-angle lens of the scene, large near, small distance, exaggerated perspective effect. The closer the subject is to the lens, the more exaggerated it becomes. Therefore, when shooting portraits, people should not be too close to the camera, otherwise it is easy to take distorted photos of "fat nose rat ears". Of course, shots with this effect

When buying a wide-angle digital camera, in addition to paying attention to the overall performance of the camera, you also need to focus on examining its lens performance. Lens distortion is the first factor we need to consider. Generally, distortion is more likely to occur when shooting at wide angles, but the degree of distortion of photos taken by different cameras is also different. In general, the less distortion the better.

Secondly, we must also pay attention to the resolution of the picture. Due to cost constraints, the lens quality of digital cameras is often not comparable to that of professional SLR lenses, especially the edge resolution of photos may be significantly reduced, while good wide-angle digital cameras are The control is relatively good, and the picture looks sharper.

There is also anti-glare capability. Because the viewing angle is wide at 28mm wide angle, it is easy to encounter backlight or side backlight. If the anti-glare ability of the camera lens is not good, it will cause difficult-to-see spots on the photo, and even impact Light phenomenon. Of course, purple fringing and dispersion are also the objects we focus on.
