Features and advantages of wide-angle lenses

Generally speaking, a lens with a focal length of 18-35 mm can be regarded as a wide-angle lens. The basic characteristics of wide-angle lens are large lens angle and wide field of vision. The range of scenery observed from a certain viewpoint is far greater than that seen by the human eye at the same viewpoint. It can emphasize the perspective effect of the picture, be good at rendering the foreground, and express the sense of distance and proximity of the scene, which is conducive to enhancing the attractiveness of the picture.

The features of a wide-angle lens

1. Provide a broader view

The wide-angle lens can make the view of the picture wider, and you can take more still life without moving backward. This feature makes the wide-angle lens particularly useful in narrow environments. Of course, shooting more widely is also conducive to shooting big scenes.

2. It has the effect of exaggerated elongation and amplification

This can be regarded as one of the common characteristics of wide-angle mirrors. Because wide-angle mirrors are naturally characterized by lens distortion, things at the edge of the picture will be elongated and enlarged. This can be regarded as a benefit or a disadvantage, mainly depending on the effect you want to express.

3. Reduce the impact of camera vibration on photos (such as hand shock)

Wide-angle photos are not as sensitive to the movement of the camera as the long focal length. If there is a little vibration, it may have little impact on the photos, and now it is very

Multi-camera and lens also have an anti-hand shock function. It is safer to use a slower shutter when shooting!

4. Bring out a sense of space

"Spatial sense" means that the scenery in the picture is far and near, large and small, which makes people feel as if they are in it and feel the environment of the place. For example, forest and grassland photography is very useful, and can increase the spatial sense of the whole picture!

5. Reduce the depth of field and lighten

One of the factors for shooting shallow depth of field is the use of a long focal length. If the focal length is shorter, that is, the wider the angle, the depth of field will be relatively shallow, and the background will be clearer.

Advantages of our LWIR lens design

• Better sensitivity at room temperature

• Better signal level for a given temperature target

• For opaque glass and plastic, it is more convenient to measure their surface temperature

• Fewer reflections in sunlight

• Higher signal-to-noise ratio

• Insensitive to visible light background interference
