What is the Role of Camera Lens In Photography?

In order to capture great images in all camera lenses should have aperture range which controls the amount of light the lens captures and thus allows photographers to control the depth of field or the distance between objects and thus enable them to capture striking photographs.

The larger the aperture range of the lens the wider the depth of field of the camera lens. Lenses with large apertures also allow photographers to let more light to pass through them and therefore produce photos with more dimension. Lenses with smaller apertures tend to produce photos with smaller dimensions and greater dimension.

What is a Camera Lens and its Role?

A camera lens is basically an optical lens assembly of many lenses mounted on a camera body and structure to create images of subjects on photographic paper, on digital media or on some other media capable of recording an image. It plays an important role in recording images from one source and transferring them to another.

The source of the images can be film/digital, TV monitors, video cameras, mobile phones and camcorders. Lenses are used for zooming and moving images, panoramic views, shots that capture multiple angles of a subject and also for photojournalism purposes. They are used for sports and action photography, wildlife photography and fashion photography.

Types Of Camera Lenses

lens type

Camera lenses differ mainly in terms of their focal length and physical sizes. Longer lenses tend to offer greater zoom capabilities and thus capture more details of distant objects while smaller lenses are suited for close up photography where they offer greater flexibility in the distance. Camera bodies have become increasingly popular over the years due to their ease of usage, flexibility and good image quality.

1. Tilt Shift Lens

When you see a photographer taking photographs with a digital camera, chances are you are seeing a digital tilt shift lens. These cameras are among the most advanced and fun to shoot photographs. Many professional photographers use this type of lens to give their photos an artistic quality. If you enjoy taking photographs with a creative eye, one of these cameras may be right for you.

Before you decide to buy a tilt-shift lens, it is important to understand what they are and how they work. Tilt-shift cameras use a mirror to move the focus from the optical lens to the digital imaging circle in the camera. The tilt-shifts are then mounted on the camera, allowing the photographer to have much more creative camera movement without being at an angle that could cause damage to themselves if they did not know exactly how to set them up properly.

Purpose

These types of lenses allow the photographer to be able to create a much larger imaging circle than they would using normal lenses. Because of this larger circle, more light is able to go through giving the photographer better image quality. Also, because the tilt-shifts are attached to the cameras, they are less likely to be damaged in the case of rough handling or drops.

Some of these lenses are fixed and can be moved only by twisting a knob to change the focus from one plane to another. Other tilting lenses are portable and allow the photographer to move their lens to a new angle by tilting the plane they wish to use. With any lens you should always do some research so that you understand exactly how each lens works and if it will give you the best results for your particular subject matter. Using an incorrect tilting plane can result in blurry images or even damage to your camera.

2. Wide Angle Lens

In photography and videography, a wide angle lens refers to a lens that has its focal length significantly smaller than the focal lengths of a normal lens on a camera or camcorder for a given camera system. This type of lens is often used for exterior photography, sports, wildlife or other special effects where a shorter focal length produces more clarity and greater subject detail than a longer lens.

Wide angle lenses are also used in architecture and design, providing a larger field of view than conventional zoom lenses. These types of lenses are not only wider angle lenses, but they can also have a high pixel rating for lower light situations, high resolution for higher image quality and high shutter speeds for shooting in low light conditions.

Typically this technique is applied when the foreground subject is small, making the whole scene brighter than the background. For large objects in the foreground, it is often more difficult to have the foreground objects in focus than the background, resulting in a “cavity” of the subject which will make everything in the foreground appear blurry.

Purpose

One common example of a wide angle lens is the lens of a camera or camcorder that is designed to provide a greater depth of field by crossing the optical path of the LCD screen. This approach is commonly referred to as “focal length doubling” or FWD. By doubling the actual focal length of the lens you can achieve a much greater depth of field and make sure that your subject is in focus.

In photography the term wide angle lens is a general description that generally refers to any lens with a fixed minimum and maximum values. It does not refer to any particular manufacturer or model. The term is most often used in landscape photography, although wide angle lenses can be purchased for most camera and camcorder types. In photography wide angle lenses allow for greater freedom in composition because they offer a bigger photo subject and increased dimension in the foreground. This allows photographers to create more striking photographs with fewer measurements and more time spent on the actual photography process.

3. Fish Eye Lens

A fisheye lens, sometimes spelled fisheye or fi-shing, is an ultra-wide angle lens which produces strong visual distortion meant to produce a wide hemispherical or spherical view. As such, it is primarily used for photographing outdoor scenes. Fisheye lenses attain very wide angles of vision thanks to the fact that they are designed in a way to cover a large area in a relatively small and compact manner. In this way, these lenses enable the photographer to cover a large area with relatively little distortion, making the resulting images look more natural.

Purpose

The diameter of the focal length of a fisheye lens depends on its overall size and, to a lesser extent, its weight. Generally, the larger the focal length, the higher the camera’s resolution and the fisheye lens’ weight. The fisheye lens can also have a very narrow aperture; however, this type of lens is more expensive. As regards resolution, a smaller aperture results in photos with lower resolution. As regards weight, a fisheye lens requires less storage space because it is smaller than standard non-focal length lenses.

Some digital cameras even have built-in fisheye lens filters to give even greater depth of field. The most common type of fisheye lens seen in digital cameras today is made of acrylic. This type of lens can be found in a number of different design elements. A popular choice is the so-called circular motorised filter. A circular motorised filter features a rotating shaft and a number of concentric circles which spin as the shaft spins.

4. Telephoto Lens

A telephoto lens in photography, often referred to as a wide angle lens, is a narrow special type of lens where the actual length of the lens itself is shorter than its focal length, sometimes as short as 1.6 inches. It has a very narrow focal length and this enables a greater degree of movement and an increased depth of field. The telephoto lens was first developed for professional use as soon as the invention of film cameras, and has remained a favorite choice ever since.

As well as being used by amateurs, particularly those involved in sport photography, telephoto lenses are also used by professionals such as wedding photographers, wildlife photographers, press photographers, fashion photographers, and those involved with scientific imaging.

Purpose

One of the most popular types of telephoto lens used for fine art and wedding photography is the large format, or large format lens. This is ideal for landscape and nature photography because the lenses are not only wider than normal lenses, but they have a more pleasing composition, as well as a greater ability to capture scenery. Landscape photography encompasses a huge array of styles and subjects, including thermals, humans, animals, and landscapes, and large format lenses enable the photographer to create a wide array of beautiful images.

The main advantage of a telephoto lens compared to a normal one is that it allows the user to get closer to subjects without having to worry about disturbing them and therefore allowing greater detail. However, these types of lenses have a tendency to be a little more expensive because of their smaller size, so it is important to understand your options. If you are looking for a telephoto lens that is not as wide, as well as not too long, then these shorter zoom lenses are the ones you should go for, although generally speaking, telephoto lenses can be a great investment, especially if you don’t mind the extra expense.

5. Macro Lens

A macro lens is a special type of lens that is used to capture images of small objects at different sizes. These lenses are great for capturing movement as well as details. For instance, if you want to take a photo of a flower bud, all you need to do is attach a macro lens to your camera and get as much detail as possible from that image. You can also use a macro lens to create a macro image of an animal, insect or another small object.

Purpose

Many people use macro lenses when taking landscape photos, but they are also great for anyone who wants to take a photo of an item, such as a coin, that is smaller than life size, such as a pebble. Macro photography has become popular because many people like to take close ups of everyday items such as flowers, leaves, cutlery and even people. The main reason why most people use these lenses is because the focal length is longer. This way, you can get as much detail as possible from the shot, rather than needing to use a shorter lens.

Another advantage of using a long, flexible macro lens is that you can adjust the distance and focus until you have created the maximum amount of detail from the object in the photo. For instance, if you are taking a shot of a bird at night, you can make the bird appear as large as possible with a shorter focal length lens, while at the same time trying to reduce the size of your object so that it is more difficult for the camera to detect the object with the human eye.

If you are interested in macro lenses, then you should know that the most important measurement for these lenses is the focal length. The focal length tells the diameter of the lens that is attached to your camera, while the aperture determines how bright the image will be. You can determine the magnification ratio by knowing the focal length and the aperture that you are using for the shot. Most professionals recommend that you use a high-magnification lens for images that require the deepest details. However, you should know that this will mean that the image will be blown up, which may not be what you are looking for.
