Comparing 30mm and 50mm Lenses: Which Is Better for You?


In this article, we will explore the differences between 30mm and 50mm lenses, and help you determine which one may be better suited to your photography needs. We’ll cover the focal lengths, aperture, image quality, and versatility of both lenses, and provide insights to help you make an informed decision.

What is the focal length of a 30mm lens and a 50mm lens?

A 30mm lens is considered a wide angle lens, providing a wider field of view and allowing you to capture more of the scene in your photos. On the other hand, a 50mm lens is considered a standard or “nifty fifty” lens, providing a more natural perspective similar to what the human eye sees. This focal length is great for portrait photography and everyday shooting.

How does the aperture differ between the two lenses?

The aperture of a lens refers to the size of the opening that allows light to pass through. A 30mm lens typically has a wider maximum aperture, such as f/1.8 or f/2.8, allowing for better performance in low light and greater control over depth of field. Meanwhile, a 50mm lens may have a slightly narrower maximum aperture, such as f/1.4 or f/1.8, although it still provides good low-light performance and background blur for portraits.

What about image quality and versatility?

Both 30mm and 50mm lenses are known for producing sharp and clear images, with minimal distortion and chromatic aberration. However, the 50mm lens may have a slight edge in terms of overall image quality, especially when it comes to capturing portraits with beautiful bokeh. In terms of versatility, the 30mm lens is great for capturing a wide range of subjects, from landscapes and architecture to street photography, making it a more versatile option compared to the 50mm lens, which is primarily suited for portraits and everyday shooting.


In conclusion, both the 30mm and 50mm lenses have their own strengths and unique characteristics. If you are looking for a versatile lens that can capture a wide variety of subjects with good low-light performance, the 30mm lens may be the better option for you. However, if you primarily shoot portraits and want to achieve a more natural perspective with beautiful background blur, the 50mm lens would be an ideal choice. Ultimately, the decision comes down to your specific photography needs and shooting style.


1. Can I use a 30mm lens for portrait photography?

While a 30mm lens is not traditionally considered a portrait lens, it can still be used for portrait photography, especially if you prefer a wider perspective or want to capture environmental portraits. However, keep in mind that you may not achieve the same background blur and subject isolation as you would with a 50mm lens.

2. Are 30mm and 50mm lenses suitable for landscape photography?

Both 30mm and 50mm lenses can be used for landscape photography. A 30mm lens will provide a wider field of view, allowing you to capture more of the scene, while a 50mm lens can help you isolate specific elements in a landscape and produce stunning compositions. It ultimately depends on your personal preference and the type of landscape photography you want to pursue.

3. Which lens is better for astrophotography?

For astrophotography, a 30mm lens with a wide maximum aperture would be better suited to capture the vast night sky and celestial bodies. However, a 50mm lens could also be used to capture specific details of the night sky and produce captivating astrophotography images.

4. Can both 30mm and 50mm lenses be used for video recording?

Both 30mm and 50mm lenses can be used for video recording, but the choice will depend on the specific requirements of your video projects. A 30mm lens may be more versatile for capturing a wide range of scenes in video, while a 50mm lens can provide a more cinematic and natural look, especially for interview or portrait-style video recording.

5. How do the prices of 30mm and 50mm lenses compare?

In general, 30mm lenses tend to be more affordable compared to 50mm lenses, as they are often considered entry-level or kit lenses. However, prices may vary based on the brand, aperture, and additional features of the lenses. It’s important to consider not only the price but also the specific capabilities and performance of each lens when making a decision.
