How to take pictures of products with a SLR camera? My product is very small, and the effect of taking it is always unclear. Ask a master to teach.

Let me answer your last question. The close-up is a magnifying glass. Just now, a friend said reading glasses are. Inverted loop is to invert your lens on your camera, with the purpose of shortening the nearest focal length and shooting objects at close range. There are advantages and disadvantages.

1, the close-up lens is cheap, and the close-up multiple is different. Like different degrees of myopia lenses. It will affect the imaging and easily deform the object. The larger the magnification, the more obvious the deformation. It depends on whether you accept the transformation.

2, anti-ring, because you still use your original lens, imaging is no problem. However, due to the electronic interface of the camera tail facing forward, unable to automatically focus exposure, etc., the camera has become fully manual. In addition, the lens is only connected with a few buttons outside the front lens, and the lens itself has weight. Therefore, the operation should be extra careful, the connection should be tight, and it is not possible to trip. In addition, the lens should not be exposed to the outside for a long time, because there is dust at the tail of the lens, which is difficult to remove.
