Holding an interchangeable-lens camera in your hand, so have you ever wondered what kind of lens this is. So what is a camera lens? What are popular camera lenses? Let Xi Pa Chao learn about this technology product!
I. What is a camera lens?
Camera lenses, also known as camera lenses, are considered by photographers to be the eyes of the cameras. Light rays in the environment must pass through the lens before reaching the viewfinder, then to the camera’s sensor to create images. The quality of the light rays and the amount of light that passes through the lens will greatly determine the quality of the image.
So Lens plays a very important role in image processing. However, not everyone who is new to photography also learns about the types of lenses, the following will be exclusively for those who are new to photographic equipment and components in general and lenses ( Lens) camera in particular the characteristics and classification of various types of camera lenses.
II. Types of Camera Lens
A camera lens is made up of many lenses and these are themselves joined together and can form the camera’s sensors. This therefore prevents the captured image from being blurred or blurred.
The focal length of a Lens will be able to help you handle the angles of view and magnify certain positions while taking a photo. Not only that, the focus will also affect the sharpness of the photos, if the focal length is longer, it also means that the time to take pictures will be shorter.
1. Lens kit
The Lens Kit is the type of camera lens that comes with an SLR or entry-level DSLR camera. Most of the specifications are low in the lens of DSLR cameras. Lens Kit is aimed at users who are novice photographers.
A Lens kit that comes with the camera can be a fixed or zoom lens, but usually it will be a zoom lens to suit many common needs of use.
Although the parameters and quality of the Lens kits cannot be as good as those of high-end camera lenses, if your budget is not very good and currently is not really in high demand, there is no need to invest more. other expensive lenses. If you know how to take advantage and exploit the strengths, the Lens kit will still give you high image efficiency.
2. Lens Prime
Prime Lens is a fixed focal length camera lens, so if you want to zoom your subject, you only have to get close to the subject.
Because of this feature, this particular type of Prime Lens is increasingly rare for zoom lenses with a wide range of focal lengths. But there are many people who like to use this Lens Prime for portrait and object photography.
Advantages of Lens Prime:
- Low price.
- For good optical image quality.
- Extremely compact with few lenses.
- Bokeh images are very beautiful.
- For the ability to expand sensory and imagination.
Cons of Lens Prime:
- The shooting focus cannot be changed.
- Focal range commonly seen in prime lenses are: 20mm, 24mm, 28mm, 35mm, 50mm, 85mm, 105mm, 200mm, 300mm, 400mm, 600mm, …
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.
4. Lens Tele
Lens Tele will give you a very impressive impression by the super large size of this lens. The telephoto lens has an extremely large 1400mm focal range called the Super Tele.
Usually when using this type of lens to shoot long range photos, wildlife photography, sports photography because of the lens’ ability to “get up close” to the subject.
Because it is a specialized lens for telephoto, sports and wildlife photography
So the price of the Lens Tele is directly proportional to the aperture of the lens and some built-in features, but all of them are not cheap, it can cost you a few thousand dollars just to own a Lens Tele.
5. Wide Lens
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.
So this type of lens is extremely suitable for shooting insects, small objects or things that are difficult for people to see clearly.
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.
8. Tilf-shift lens
Tilf-shift lenses are special lenses and have an unusual function for an enjoyable shooting experience. This type of lens has a mechanism that rotates and slides the lens and creates a plane parallel to the plane of the image to accurately capture the subject, often used for architectural photography.
In addition, this type of lens also produces images with an effect in which the subject feels smaller than usual. Only the remaining visible focus will be blurred, giving you the feeling of viewing a single-model Macro photo.
As for the price of this type of lens, it is extremely expensive.
