0.45 X 52mm Wide Angle Camera Lens For Nikon Coolpix D3100 D5600 D3400 37-52mm

Features:
A wide-angle lens is a photographic lens with a focal length shorter than that of a standard lens, an angle of view larger than that of a standard lens, a longer distance than a fisheye lens, and a smaller angle of view than a fisheye lens. Wide-angle are divided into rdinary wide-angle and ultra-wide-angle . The focal length of the rdinary wide-angle lens of the 135 camera is generally 38-24 mm, and the angle of view is 60-84 degrees; the focal length of the ultra-wide angle lens is 20-13 mm, and the angle of view is 94-118 degrees. Because the wide-angle lens has a short focal length and a large angle of view, it can a large area of ??the scene within a short shooting distance.

The principle and characteristics of the wide-angle additional mirror: The front wide-angle lens is actually an inverted system. It "expands" parallel rays coming from a distance before entering the lens for imaging. This is equivalent to moving the main surface backward and shortening the focal length. According to the same reason, the value of the aperture F number after adding the front wide-angle lens is unchanged.

The effect of using a wide-angle additional lens has the following characteristics:

1. It can increase the depth of space in the photographic picture.

2. Long depth of field can ensure that the front and back scenes of the subject are clearly displayed on the screen.

3. The lens covers a large area, and the range of scenery shot is wide.

4. The scene taken outside the same shooting distance is smaller than the scene taken with a standard lens.

5. the defects of perspective distortion and image distortion are easy to appear in the screen. The shorter the focal length of the lens, the closer the shooting distance, the more obvious this defect.

The effect of the wide-angle lens:

1. It can increase the depth of space in the photography picture;

2. The depth of field is long, which can ensure that the front and back scenes of the subject can be clearly reproduced on the screen;

3. The lens has a large coverage area and a wide range of sceneries;

4. The scene shot at the same shooting distance is smaller than the scene shot using a standard lens;

5. It is the defect that perspective distortion and image distortion are easy to appear in the screen. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is.

6. Small size, light weight, easy to load and unload, and easy to carry.

7. Increasing the coverage of the field of view during photography, shooting more incomplete scenes.

8.The mirror surface adopts high transmittance multi-layer coating to increase the lens, enhance the image contrast and reduce the to reduce the dispersion and image.
