3. Lens Zoom

In contrast to Lens Prime, the Lens Zoom is a lens with a variable focal range. For that reason, this lineup of camera lenses has many different types from aperture and focus to features that are incorporated into DSLR camera lenses.

For Lens zoom, the photographer can zoom in a focal range from 18mm to 300mm. A G OSS E 70-350mm F4.5-6.3 lens for 350mm stabilization can also meet common needs such as photography, sports, portraits, or even telephoto.

Wide Lens also known as wide angle lens allows you to easily capture the whole scene. Usually a standard lens has a focal length of about 50mm.

The 50mm focal length gives a true-to-life angle close to the spatial perception of the human eye. With lenses that are more expansive than the standard angle of view (i.e. with a focal length less than 50mm) it will be called the Wide Lens (wide-angle lens).

If the photographer wants to capture everyone in a large room, a Wide Lens will be the best choice. Wide angle lenses are also divided into three categories:

  • Wide angle
  • Super wide angle
  • Ultra wide angle

By traditional standards a super wide-angle lens will have a focal length of less than 20mm. A wide angle lens will usually have a 21 – 35mm focal length.

6. Lens Macro

This is a special type of lens used by many photographers, with the ability to focus very close to the subject, closer than usual, and provide an aspect ratio of 1: 1.

7. Lens Fish Eye

Fisheye lenses are very special lenses when they have a wide angle and produce spherical panoramic images. The photo will look like it was viewed inside by a convex bridge. The Fish Eys Lens creates a distinctive visual effect and gives a wider angle when using a conventional wide-angle lens.
