A camera is an instrument that we used to capture moments. The camera consists of parts like a light-tight box (main body), a light-sensitive sensor, lenses, etc. 

The camera is incomplete without the lenses. The lens acts as a filter for the camera because it collects and lets in the proper amount of light and at the same time protects the sensor from damage due to light.

In this article, we’ll know about different types of lenses and their purposes. As a result, you may select a proper lens that fits your requirements.

Lens and Its Importance In a Digital Camera

The lens is as crucial as the main body of the DSLR camera. Most DSLR cameras are useless without the lens.

There are some exceptional cameras but in the case of most DSLRs lens is a must.

Following are the main functions of a lens that makes a DSLR complete.

Control over the Light

The lens’s primary role is to gather and regulate the quantity of light that goes through it to the aperture. The aperture responds differently to the various scales of incoming light the lens.

The aperture adjusts the hole to gather the proper quantity of light according on the amount of light. Where the amount of light is relatively low, the aperture opens a larger hole to capture the maximum quantity of light.

In a summary, you won’t be able to adjust the light.

Protect the Sensor

The sensor is the DSLR camera’s photoreceptor, which response to light passing through it. It is the most important component of a DSLR camera, without which no scene, whether picture or video, can be captured.

Light, as we all know, goes through the lens. The amount of light that passes through the aperture to the sensor is controlled by the lens. It shields and protects the sensor from an excessive quantity of light, which might cause significant harm to the sensors.

When the lens is disconnected, we cannot expose the camera to light. The lens serves as a cover for the lens, which we use to keep it in the bag.

Here is an infographic showing 6 different types of lenses.

Optics is classified into three varieties based on focal length: wide-angle (short-focus), normal, and telephoto (long-focus).

Wide-angle lenses improve the perception of space inside a frame. It is appropriate for landscapes and sceneries with a broad field of view.

Wide-angle lenses are further classified as ultra-wide-angle, medium-wide-angle, and wide-angle.

Normal lenses have a neutral action, which means they don’t have a telephoto or a wide-angle effect. Such optics convey perspective like a human eye. It is suitable for portraits.

Because of the narrow angle of view, a telephoto can capture a limited field. Telephoto lenses push things closer to produce a tight framing.

It is also useful for photography of animals and anything else that cannot be approached easily.

Different Types Of Lenses And Their Purpose

As we all may know that there are a lot of different types of lenses that photographers usually use. But all these lenses do not work the same.

To be precise, all the lenses are designed to be used for different purposes. They are all experts in respective fields.

If you don’t have much knowledge about the cameras and lenses, you have to consider your requirements and then buy one.

Here we have some main different types of lenses discussed below. There are two types of camera lenses, Prime Lens and a Zoom Lens.

Prime Lens

prime-lens-different-types-of-lenses

This is a lens with a definite field of view. That means we cannot change our focus without moving physically. It has a fixed focal length. 

Due to the minimal moving parts and the fixed focal length the prime Lens gives you the best quality pictures possible which are without a doubt better than a zoom Lens. 

Also, 

Zoom Lens

On the other hand, a zoom lens enables us to capture pictures at a different focal length using a single Lens and without moving physically.

That’s the main purpose of a zoom Lens.

The zoom lenses increase flexibility in shooting by pulling in and pushing further the objects you intend to catch in your camera.

We have learned basic types of camera lenses. Further, we are going to classify the lenses based upon their range of focal length and respective purposes.

1. Standard Lens

This Lens is known as a standard lens because of the diva’s length of the lens. Its range lies between 35 mm to 85 mm.

This Lens is the most commonly used. It gives most natural results than other lenses.

The focal length that standard lens has generally had a field of view that we see by our bare eyes. So such lens is commonly used for documentary, videography as it captures what we naturally see. 

The standard lens is an essential gear for every photographer and videographer. Everyone at least has one standard lens. A 50mm lens is the most popular lens in all.

2. Wide Angle Lens

wide-angle-lens

The lens has a focal length shorter than the length of the sensor or film is known as a wide-angle lens. The focal length ranges between 24 mm to 35 mm.

The ultra-wide-angle lenses lie between 23mm to 16mm. 

This type of lens allows us to shoot a wider scene than a standard lens. This is a popular lens for taking landscapes and is also commonly used in the architecture field because of the wide field of view. 

The wide-angle lens causes distortion at the edges of the frame. To solve this issue, you may use photo editing.

But it would be better if you avoid placing objects at the corners and edges of the frame.

3. Fisheye Lens

The ultra-wide lenses that produce more often distorted images are fisheye lenses. They are named like this is due to their vision being similar to the first eyes.

The focal length of these lenses lies between 16 mm to 1 mm. All the lenses lying in these divas lengths are categorized as fisheye lenses.

As you may know, the images captured with these lenses are not normal. The field is view is fast wider than the human vision. 

That’s why such kind of lens is used only for a specific purpose like abstract photography or underwater photography.

This lens is capable of capturing photos up to 180° view. But such images may end up being circular as they are highly distorted.

Other than those specified purposes, it is not favorable to use this kind of lens.

4. Telephoto Lens

These lenses have a longer focal length than a standard one. These are specialized in shooting objects from a long distance.

The focal length of these lenses is 85 mm and above. These lenses are also large. 

These lenses are capable of capturing objects from a long distance due to their magnification ability. They make objects appear closer. 

The more the focal length is, the narrower the field of view becomes. Hence, these lenses perfectly capture particular objects and making the rest background blur.

A short telephoto lens (85 mm – 135 mm) is commonly used for portrait photography.

5. Macro lens

These different types of lenses are used for taking extra close-up shots. They are specialized in giving extraordinarily detailed shots with high contrast and sharpness 

It generally has a focal length range varying from 35 mm to 200 mm. Due to such focal length and its mechanism, it is capable of capturing objects at their actual physical size on the frame (1:1) or at a greater size too.

It magnifies objects to capture very tiny details.

These lenses are commonly used to capture flowers, insects, other natural elements, etc. Also, they are so popular in fine art photography, product photography.

These lenses are designed to focus on nearby objects and magnify those. So, that they are unable to capture long-distance objects.

Conclusion

With this much knowledge, anyone will be able to select an appropriate lens best fitted for their purpose. 

The whole article has classified different lenses based upon their mechanism and utilities. By referring to the above classification, you may conclude that for portrait photography you may choose a standard lens or a short telephoto lens.

Similarly, for architecture, landscapes you may buy a wide-angle lens, and so on.
