What Do The Camera Lens Numbers Mean ?
The camera lens numbers, also known as focal lengths, can often be confusing to photographers who are just starting out. It’s not obvious at first what the numbers mean and how they affect the kind of photos you take. In this article, we’ll take a closer look at what camera lens numbers mean, how they affect the way you take photos, and how to choose the right lens for your needs.
1.What Do Camera Lens Numbers Mean?
Camera lens numbers are a measure of the focal length of the lens, which is the distance between the point of focus of the lens and the film or digital sensor in the camera. It is usually expressed in millimeters (mm). The smaller the number, the wider the angle of view, and the larger the number, the narrower the angle of view. A wide angle lens has a short focal length (usually less than 35mm) and a telephoto lens has a longer focal length (usually more than 70mm).
2.How Do Camera Lens Numbers Affect Your Photography?
The camera lens numbers affect the way you take photos in several ways. Wide angle lenses allow you to capture more of the scene in a single shot, while telephoto lenses allow you to zoom in on a particular subject. They also affect the depth of field, which is the area of the image that appears in focus. A wide angle lens has a large depth of field, meaning more of the image will be in focus, while a telephoto lens has a shallow depth of field, meaning only a small part of the image will be in focus.
3.How to Choose the Right Lens?
Choosing the right lens for your needs is important, as it will affect the way you take photos. If you’re shooting landscapes, a wide angle lens is best, as it will allow you to capture more of the scene in a single shot. If you’re shooting portraits, a telephoto lens is best, as it will allow you to zoom in on your subject and blur out the background. If you’re shooting in low light, a lens with a large maximum aperture (usually f/1.8 or greater) will allow you to capture more light and get better shots.
In conclusion, camera lens numbers can be confusing at first, but understanding the basics can help you take better photos. Knowing the difference between a wide angle and telephoto lens, and how the lens numbers affect the depth of field and other aspects of photography, can help you choose the right lens for your needs. With the right lens in hand, you’ll be able to capture stunning images that you’ll cherish for years to come.
