Is the lens of Sony a5 100 a wide-angle lens?

This is Sony's micro-single, and the lens can be changed. So the so-called wide-angle lens is still a standard lens. Actually, it depends on what lens to match.

At present, Sony (ILCE-5100APS-C) micro-single lens group (24.3 million effective pixels 16-50mm lens F3.5-5.6A5100L/α 5100) on the market is equipped with 65438.

The so-called wide-angle, standard and telephoto lenses are generally distinguished as follows:

standard lens

For a general 135 SLR camera, a photographic lens with a focal length of 40mm to 60mm is called a standard lens.

If you stand at the same point and look at the same scene with different lenses, then the standard lenses are a set of lenses closest to people's normal vision. (That is to say, the range of scenery seen by the naked eye is basically the same as that of the standard lens. )

Generally speaking, the standard lens has the best rendering effect and the ability to show details is slightly better than the other two groups of lenses at the same level.

wide-angle lens

Similarly, for a 135 SLR camera, a photographic lens with a focal length below 40mm (17mm-35mm) is called a wide-angle lens.

At the same position, the visual range of a wide-angle lens is much wider than that of a standard lens, and this is the characteristic of a wide-angle lens, that is, its visual range can be wider than that of the naked eye. In this way, the wide-angle lens can help the photographer to achieve a complete shooting effect when facing a large subject and there is not enough step behind.

Another feature of wide-angle lens is that it is easy to cause deformation around the picture, but it is precisely this feature that photographers also use to take photos with special themes, that is, fisheye lenses (generally, lenses with a viewing angle close to 180 are called fisheye lenses).

long shot

Similarly, for a 135 SLR camera, a photographic lens with a focal length exceeding 60mm (60 mm-400 mm) is called a telephoto lens.

The telephoto lens has a telescope-like function, which can help to shoot distant objects. But its visual range is much smaller than the naked eye (small viewpoint). Convenient long-distance snapshot.

Telephoto lenses are generally bulky and inconvenient to carry, because they are not as good as standard lenses because of the long viewing distance and the influence of air and thermal refraction.

There is also a telephoto lens with a 60- 135 mm part, which is called a medium focal lens. In fact, it is similar to a telephoto lens, but the magnification effect is not obvious.

Generally speaking, however, this zoom can be made finer, and the phase effect will be better than that of a lens with a longer focal length, which is suitable for ordinary photographers, not bulky and convenient to carry.
