People who are new to photography may often hear about two lenses, the 18mm-55mm kit lens and the 50mm prime lens. 

If you are not familiar with the features of a lens, these two may not have much of a difference. 

Is a 50mm Lens Better Than an 18-55mm Lens? 

Based on the features, the images that it produces and its overall built, the 50mm prime lens is better than the 18mm-55mm lens. 

However, that does not mean that the 18mm-55mm does not have its own advantages.

Difference Between a 18mm-55mm Lens and a 50mm Lens

The biggest difference between the two lenses is their type. The 50mm is a prime lens with a fixed focal length, so it can’t be zoomed in or out. As for its aperture, it is wide enough to be used in the dark, or at night time

Meanwhile, the 18mm-55mm kit lens is categorized as a zoom lens that can change focal lengths and allows for more versatility. However, its aperture is narrow, so it can’t be used in low light areas, you might be required to use an external flash.

Benefits of a 18mm-55mm Lens

The 18mm-55mm lens is the kit lens that comes with the DSLR that you purchase. It has an aperture range of f/3.5 to f/5.6 which is ideal for wide-angle and zoomed pictures. 

The outcome of your images will depend on the focal length range that you use. If you go for the wider angles, you can use the lens for the following types of photography:

  • Architecture 
  • Landscape
  • Real Estate
  • Automotive
  • Nature
  • Family

Aperture of a 18mm-55mm Lens

The 18mm-55mm kit lens shares the same aperture regardless of the brand. The aperture of a kit lens is f/3.5 to f/5.6. If you are using the 18mm focal length, the aperture will be f/3.5. If you are using the 55mm focal length, the aperture will be f/5.6. 

A kit lens is smaller and lighter compared to other zoom lenses, so they are perfect for travelling. The downside is that the quality of the image changes drastically based on the focal length. 

For example, if you use the 18mm focal length, distortion will be visible when you switch to 55mm. To combat this, you will need to make some adjustments on the shutter speed of your lens. 

Benefits of a 50mm Lens

The 50mm prime lens has a different set of advantages compared to the 18mm-55mm lens. It is a fixed focal length which means you can only take pictures of your subject from a distance. 

Despite not having a zoom option, it has a very fast and wide aperture of f/1.8, which is ideal for taking pictures in low lit areas. It also creates a beautiful background blur on your pictures. 

The types of photography that the 50mm lens covers are:

  • Astro
  • Portraits
  • Blue Hour

Aperture of 50mm Lens 

The 50mm has a wide aperture of f/1.8. It is two stops brighter than the aperture of the 18mm-55mm lens. Even though you won’t use the f/1.8 aperture on all of your pictures, it can still create a beautiful look on the images. 

Since the aperture is wide, it will naturally create a shallow depth of field. It can also naturally create a background blur and creamy bokeh
