Product introduction:Close up lens:
It is a kind of close-up accessory similar to a filter. When you use it to observe the scene alone, it is like a magnifying glass. Its front side is raised for image magnification, but its back side is slightly concave, so as to reduce the image field bending to a certain extent.
The close up lens is a kind of simple micro distance shooting tool. The advantages are convenience and no need to compensate the exposure; The disadvantages are spherical aberration, barrel distortion, and the lens focusing is limited to a very narrow range after the use of proximity lens.
Close up lens - main functions
Using this lens, the lens can focus on objects much closer than usual to produce close-up images, such as taking pictures of flowers, insects, etc. or reproducing text.
How to use the proximity lens: manual focusing is recommended
There are six multiples of proximity mirror, many friends do not know how to choose, let me introduce to you: generally, No. 2 mirror can shoot Magnolia sized scenery, No. 3 mirror and No. 4 mirror can shoot flower and bee sized scenery, No. 8 mirror can shoot ant sized scenery, No. 10 mirror can shoot ant's feet!
instructions:
1. In most digital cameras, the macro range is at the wide-angle end, while the long focus end does not (the shooting distance of the long focus end is 0.6-1m). After using the proximity lens, the shooting distance of the long focus end can be greatly shortened. Example + 4 close up lens < = 250mm
2. The close up lens is + 1 + 2 + 3 + 4, which is the diopter. The focal length of + 1 is 1000mm, the focal length of + 2 is 500mm, the focal length of + 3 is 333mm, and the focal length of + 4 is 250mm
3. The digital camera front end adds the close camera lens to take the flower, the insect or the reproduction document, the pattern and so on, the photography effect is very good
4. The exposure will not be affected by adding a close camera, but the depth of field will be shortened. The camera should be stable and easy to use a tripod.
5. Because of the natural structure of the proximity lens, the edge definition of the enlarged image will be a little worse, and there will be a little image distortion, but the image is basically unchanged, which does not affect the overall effect.
