What Is Focal Length?
When it comes to understanding the basics of photography, one concept that is crucial to grasp is focal length. Whether you are a beginner or an experienced photographer, having a good understanding of focal length can significantly improve your skills and the quality of your images. In this blog post, we will explore this concept and its impact on photography.
Focal length defined
Focal length refers to the distance between the camera’s sensor and the lens’ optical center when the lens is focused at infinity. It is typically measured in millimeters (mm) and determines the field of view and magnification of the image. In simple terms, it is the property of the lens that controls how much the subject will be magnified and how much of the scene will be captured in the frame.
To understand the concept more clearly, let’s consider an example. Imagine you have two lenses, one with a focal length of 50mm and another with a focal length of 200mm. The 50mm lens will capture a wider area of the scene compared to the 200mm lens, resulting in a larger angle of view. On the other hand, the 200mm lens will magnify the subject more, narrowing down the angle of view and bringing distant objects closer.
How focal length affects the image
The focal length of a lens has a significant impact on the final image. It affects two main aspects: the magnification of the subject and the perspective of the scene. Understanding these effects can help you make more informed decisions when choosing your lenses and composing your shots.
1. Magnification: As mentioned earlier, the focal length determines how much the subject will be magnified. A shorter focal length, such as 24mm, will result in a wider field of view, capturing more of the scene but offering less magnification on the subject. On the other hand, a longer focal length, like 200mm, will narrow down the field of view, but provide more magnification, making the subject appear larger and closer in the frame.
2. Perspective: Focal length also affects the perspective of the scene. A shorter focal length exaggerates the distance between objects in the frame, making them appear further apart and emphasizing the depth of the scene. This effect is often used in landscape photography to create a sense of vastness. In contrast, a longer focal length compresses the scene, reducing the perceived distance between objects. This effect is commonly used in portrait photography to create a pleasing and flattering appearance.
Illustrating the concept with examples
To further illustrate the concept of focal length, let’s consider a few examples:
- A wide-angle lens with a focal length of 16mm will capture a large portion of the scene, making it suitable for landscape photography or capturing vast architectural structures.
- A standard lens with a focal length of 50mm is often considered a versatile option, closely resembling the human eye’s natural perspective. It is commonly used for street photography, portraits, and everyday situations.
- A telephoto lens with a focal length of 200mm or longer can help you capture distant subjects, making it ideal for wildlife or sports photography where you need to get close despite the physical distance.
By understanding how focal length affects the image, you can better choose the right lens for the desired effect and compose your shots with more intention. Experimenting with different focal lengths can also add variety and creativity to your photography.
Prime Vs. Zoom Lenses: Choosing The Right Focal Length
When it comes to choosing a lens for your photography equipment, one of the key factors to consider is the focal length.

Whether you opt for a prime lens or a zoom lens, understanding the difference between the two and knowing how to choose the right focal length can greatly impact the quality and effectiveness of your images.
Difference between Prime and Zoom Lenses
Before diving into focal length selection, let’s first understand the difference between prime and zoom lenses. Prime lenses have a fixed focal length, which means they don’t offer the flexibility of zooming in or out. On the other hand, zoom lenses provide a range of focal lengths, allowing you to adjust the magnification to your desired composition. While prime lenses may seem limited in terms of flexibility, their fixed focal length often results in superior image quality and wider maximum apertures.
Factors to Consider when Choosing Focal Length
When deciding the focal length that suits your photography needs, several factors need to be taken into consideration:
- Subject and Genre: The type of photography you specialize in will greatly influence the ideal focal length. For example, landscape photographers may prefer wider focal lengths such as 14mm-35mm, while portrait photographers often opt for longer focal lengths like 85mm-135mm to achieve a pleasing compression effect.
- Distance: The distance between you and your subject plays a crucial role in determining the appropriate focal length. For close-up shots or macro photography, a shorter focal length like 50mm-100mm can work well. In contrast, distant subjects may require telephoto lenses with focal lengths exceeding 200mm.
- Depth of Field: If you prefer a blurred background or shallow depth of field, a lens with a wider maximum aperture is recommended. Prime lenses with low f-numbers, such as f/1.8 or f/1.4, can achieve this effect more effectively than most zoom lenses.
- Portability: Consider the weight and size of the lens, especially if you often shoot on location or during travel. Zoom lenses usually offer more versatility in a single lens, but they tend to be larger and heavier compared to prime lenses.
Popular Focal Lengths for Different Types of Photography
