What Size Camera Lens Do I Need?
Now that you’ve overseen the list of content, let’s take a deeper dive into the article to get some basics clear in order to understand what’s the right kind of lens for you to buy.
1. The Basics: Focal Length
To better understand, let’s first discuss what focal length in photography means. Focal length is the characteristic of the lens (usually given in mm) that defines how much area of a scene the camera is able to capture.
The focal length of a lens is inversely related to the angle of view of a scene. If the focal length is longer, the angle of view produced is narrower and higher magnification. Similarly, a short focal length dictates a wider angle of view and a lower magnification as well. Now, let’s try to use this concept in defining the different types of lenses.
2. Categorization of Lenses
Broadly, all of the camera lenses can be divided into two main categories: Prime lenses and Zoom lenses. In the next section, we’ll get a brief and basic idea of what both of these lenses are and how they differ.
2.1 Prime Lens
A Prime lens comes with a fixed focal length. This also means that the lens doesn’t allow the zoom in and zoom out feature. The very fact that prime lenses don’t have any extra glass in order to zoom, makes these kinds of lenses to be smaller, lighter and produce sharper images than their counterparts – Zoom lenses.
Since the prime lenses are fine-tuned to function with a specific focal length, they intend to deliver higher quality images than zoom lenses. The standard 35mm, 50mm, and 85mm lenses are the most widely used prime lenses. The 50mm prime lens is a recommended and popular choice for portrait photography.
2.2 Zoom Lens
The most common type of lens that you will come across in the photography world is the zoom lens. Zoom lenses come with a defined range of focal lengths, making them diverse and versatile than the previously mentioned prime lenses.
Due to its versatility, the zoom lens offers great freedom of choice in the creative realm, from street art photography to wildlife action shots. The most popular zoom lens is the 70-200mm with which you can zoom all the way from 70mm to 200mm. Because of its wide range of applicability and adaptability, the zoom lens is considered an all-around lens typically recommended for beginners.
3. Different Types of Lenses
From Wide Angle to Fisheye lenses, this section will cover all major types of lenses that you’ll come across in the market or on the internet. Let’s get a better understanding of each lens:
3.1 Wide Angle
What size camera lens do I need? : Wide Angle Lens
A wide-angle lens, as clearly suggested by its name, corresponds to a wider field of view. This helps to capture more of the same scenery than the above-mentioned standard zoom lens. Wide-angle lenses are the go-to lenses for landscape photography.
In regards to focal length, a wide-angle lens refers to a lens below 35mm. These lenses are categorized as standard wide-angle lenses with focal lengths between 35mm and 24mm; wide-angle with focal lengths between 24-16mm and ultra-wide-angle lenses below 16mm.

In addition to landscape photography, wide-angle lenses are great for interior architectural photography and large group photos in confined spaces. The most popular wide lenses fall under the 16-35mm range.
What size camera lens do I need? : Fisheye Lens
Fisheye lenses are a special type of wide-angle lenses, sometimes referred to as ultra wide angle lenses, to provide an enormous field of view. These lenses have a 180-degree angle of view that gives them the unusual fisheye effect.
The focal length of fisheye lenses can be as low as 8mm which helps them to capture as much scene information as possible. These lenses give off a hemispherical type of view similar to the GoPro action cameras.
What size camera lens do I need? : Telephoto Lens
If a standard zoom lens doesn’t cut it, then you’ve got to level up to a telephoto lens. These lenses are not suitable for budding photographers as these lenses conform to special needs and are rather bulky and possibly out of a beginner’s budget.
Telephoto lenses have focal lengths ranging between 70-200mm with Super Telephoto lenses working in the 300-600mm range. This makes them suitable for sports photographers as well as nature and wildlife photography to get a close and clear shot of the subject.
What size camera lens do I need? : Macro Lens
Macro lenses are popular for their extreme close-up photography. These lenses come with a closer focusing ability than the usual lenses which helps them to reproduce a 1:1 life-size ratio of the focussed subject. Macro lenses are widely used for capturing small products or objects such as flowers, insects, etc.
