What’s the best lens for me?
An interchangeable lens for every application |

Do you want to go carefree with your camera on vacation? Or are you going into the Himalayas on the hunt for a snow leopard? It does affect which lens you bring. To better tailor-make our series of lens advice, we've divided photographers into 4 types in "How do I choose a lens?": starters, amateurs, prosumers and professionals. We've asked you for your favorite subject because that determines partly what the best lens is for you. To make the lens offerings clearer, we divide lenses into 10 groups, which you may already know from our overview of lens reviews: | ![]() |

What is distortion?
When an image does not match reality, it's distorted. There are several ways a lens can distort your image ans some are associated with the design of the lens, while other types of distortion are caused by the photographer. Distortion of an image doesn't necessarily have to be visible to the naked eye. Usually, you'll encounter horizontal and vertical geometrical distortion. These two types of distortion are no lens errors, but have to do with the perspective from which the photo is taken. Vertical and horizontal distortion are caused by the orientation of the camera relative to the subject. Barrel or pincushion distortion is caused by lens errors. Less than 1 percent of barrel or pincushion distortion is no longer visible in most photos, except for architecture images. With a fisheye lens, this distortion is very large, but deliberately present. | ![]() |

What is chromatic aberration
Chromatic aberration occurs when light breaks in a lens: colors shift towards each other. The most famous example of refraction is probably a rainbow, where the rain drops shift the colors of the sun towards each other. In practice, we mostly see chromatic aberration in the farthest corners of recordings with sharp transitions from dark to light. How do you recognize chromatic aberration? The picture on the right shows an extreme example of chromatic aberration, where, next to the branches, ugly magenta and blue spots come into existence. | ![]() |
