Why are good camera lenses so important?



Camera lenses are more important than the camera they are connected to, at least in most situations. An entry level DSLR with a good lens will take great shots while a professional camera of $ 10,000 with a horrible lens will take awful pictures. Here's why.

Cameras are just really good

A major cause cameras do not matter much longer, it is also that access models are excellent. Imagine how much the camera in your smartphone has improved over the past decade. With the much larger sensor in DSLR and mirror-free cameras, the difference is even more distinct.

This is a shot that I brought my Canon 650D on five levels with a 50mm f / 1

.8 lens. 19659004]

And here's a shot with my professional, newer, Canon 5D III with the same lens.

When shooting good light and showing your pictures online, there is not much difference in quality between images produced by both cameras. There are other advantages with more expensive cameras, but pure image quality is not the biggest.

What comes in the light of light

So, let's get to the bottom line: everything that comes in between the scene you shoot and the camera's sensor affects the quality of the image. It's easy to test this yourself: Just take a photo through any window. Even though you can see through it clearly, the quality of the photo you take will hit hard.

Just look at this photo I took from a plan. It's a good photo, but it's easy to see how the extra glass panes make it all a bit blurred.

Each lens consists of several different lens elements. Each element affects the light as it passes through. With expensive lenses, manufacturers are widely used to use top quality technologies and materials to minimize any chromatic aberration, distortion or vignetting from how the elements affect the light as it passes through. Expensive lenses tend to be sharper throughout the picture for the same reasons. With cheaper lenses, manufacturers can not afford to invest so much money in materials or research. They try to do their best, but compromises must be done, and the quality of the image is one of the things that suffer.

I'm not wrong, there are great, affordable lenses out there – check out our articles on good lenses for Canon and Nikon cameras, but they still cost between $ 150 and $ 600. All cheaper are probably badly done and have a serious impact on the quality of your pictures.

Lens Control What You Can Shoot

Your camera is just a stupid image, brick. Without a lens, all you can do is take selfies like this:

I'm so sexy.

It's the different lenses you have that allow you to shoot different situations and subjects. If you want to shoot at night you need something with a nice wide aperture. For sports or wildlife photography, a phone sensor is ideal. The best portraits and the best scenery use completely different lenses.

While it's possible to shoot different subjects without the "right" lens – I shoot lots of sports products with a wide-angle lens – making your life much more difficult. Choosing the right focal length lens for your subject is a major part of the photography.

Lens Last

Cameras are outdated in a few years. New developments, new technology and so on. However, lenses are updated much less often. If you look for your lenses, they will go through several different camera bodies as long as they are compatible. Therefore, we recommend that you carefully consider purchasing specific lentils for the harvest sensor.


Buying good lenses is an investment. You are much better to spend $ 500 on a camera and $ 1000 on good lenses than vice versa. They have more effect on image quality, determine what you can shoot and will go further.
