What lens does Taobao commodity photography need?

Use a 50 mm standard fixed-focus lens. Fixed focus lens has no zoom function. The design of fixed-focus lens is much simpler than that of zoom lens, but the general zoom lens will affect the imaging when zooming. The biggest advantage of fixed-focus lens compared with zoom machine is its fast focusing speed and stable imaging quality.

Many digital cameras with fixed-focus lenses have clear and stable images of moving objects, very accurate focusing, delicate pictures, very slight graininess and relatively accurate metering.

Advantages of fixed focus lens:

Features of the lens:

1, standard lens;

1) standard lens: Take the interchangeable lens suitable for 35mm single-lens reflex camera as an example. The standard lens usually refers to a photographic lens with a focal length of 40 to 55 mm, which is the most basic photographic lens of all lenses. The standard lens gives people a vivid visual effect picture, so it is often used in actual shooting.

2) On the other hand, because the picture effect of standard lens is very similar to the visual effect of human eyes, the picture effect shot with standard lens is very ordinary, even very "plain", and it is difficult to obtain the artistic effect of rendering the picture like wide-angle lens or telephoto lens.

2. telephoto lens;

The telephoto lens has a viewing angle of less than 20 degrees and a focal length of several tens or hundreds of millimeters. A telephoto lens has a long focal length, a small viewing angle and a large image on the negative. Therefore, at the same distance, you can take larger images than the standard lens. Suitable for shooting distant objects.

3. Wide-angle lens;

1) Take a 35mm single lens reflex camera as an example. A wide-angle lens usually refers to a lens with a focal length of 17 to 35mm.

2) The basic characteristics of a wide-angle lens are its large viewing angle and wide field of vision. The range of scenery observed from a certain viewpoint is much larger than that seen by human eyes at the same viewpoint; The depth of field is long, which can show a fairly clear range; It can emphasize the perspective effect of the picture, be good at exaggerating the foreground and express the sense of distance of the scene, which is conducive to enhancing the appeal of the picture.
