Near camera:
It is a kind of near-view accessory similar to a filter. It is like an magnifying glass when viewed separately. Its front is raised for image amplification, but the back is slightly concave, so as to reduce the bending of image field to a certain extent.
The near lens is a simple micro range shooting tool. The advantages are convenient and no compensation for exposure; the disadvantage is that there is spherical error, which is characterized by barrel deformation distortion. Moreover, after the close lens is used, the focus of the lens is limited to a very narrow range, and can not be focused far or near.
Proximity mirror - main functions
This mirror can focus the lens on objects much closer than usual, producing close-up images, such as flowers, insects, etc., or remake words.
The method of using the camera: it is recommended to focus manually
There are 6 kinds of multiple near camera. Many friends don't know how to choose. Let me introduce it to you: basically, mirror 2 can shoot the jade orchid size scenery, mirror 3 and mirror 4 can shoot the flowers and bees, and mirror 8 can take ant size scenery, and mirror 10 can shoot the feet of ants
instructions:
1. Most digital cameras have a wide range of micro distances, but no long focus end (the shooting distance of the long focus end is 0.6-1m). After using the close camera, the shooting distance at the long focal end can be greatly shortened. Example: +4 near camera <=250mm
2. The lens is +1 +2 +3 +4, which is the refractive index, the focal length of +1 is 1000mm, +2 is 500mm, the +3 is 333mm, and the +4 is 250mm
3. The camera is close to the front of the camera to shoot flowers, insects or remake files and patterns, and the shooting effect is very good
4. The exposure is not affected by the close up of the camera, but the depth of field is shortened, and the shooting time should be stable, and the tripod can be used.
5. Due to the natural structure of the near camera, the sharpness of the edge of the image will be slightly worse after amplification and there will be a little distortion of the image, but the image has not changed basically, which does not affect the overall effect.
