What is a zoom lens?
Lenses come in all kinds of types, sizes, and price ranges. If you start looking for a zoom lens, you’ll quickly discover that the selection available today is enormous.
But what exactly is a zoom lens? What can you photograph with it, and how do you make the best choice? In this blog, we’ll explain everything you need to know!
Zoomlens
A zoom lens is exactly what the name suggests: a lens with a variable focal length. This makes it easy to bring subjects closer while photographing, without having to move yourself. You simply adjust the zoom by turning the ring on the lens.
In many cases, you’ll physically see the lens change shape, for example by extending or retracting. Of course, there are also exceptions where the lens maintains the same length throughout the zoom range.
A zoom lens is designed differently from a prime lens. This is mainly because it needs to support multiple focal lengths within a single lens. But what does this mean for you as a photographer?
You’ll mainly notice the difference in terms of light performance. Zoom lenses often have a smaller maximum aperture, which is usually not constant throughout the entire zoom range. As a result, the lens lets in less light — something you’ll especially notice in low-light situations.
The pros and cons at a glance
Like every lens, zoom lenses come with both advantages and disadvantages. Keep in mind that what may be a disadvantage for one photographer can actually be an advantage for another. It all depends on your personal needs and shooting style.
We’re happy to help you decide whether a zoom lens is the right choice for you.
Advantages of a zoom lens
✔ Easily change your framing by zooming in and out, without having to move yourself.
✔ Versatile and practical thanks to the wide focal range.
✔ Changing lenses becomes almost unnecessary.
Disadvantages of a zoom lens
✘ Less sharpness and detail compared to a prime lens, because the lens has to perform well across the entire zoom range.
✘ Generally heavier and somewhat slower in autofocus performance.
✘ They can be quite expensive if you want the best possible image quality.
When should I buy a zoom lens?
A zoom lens is often a great addition to your photography setup, but it’s important to carefully consider the investment, as it can come with a relatively high price tag.
Fortunately, most beginner cameras come with a standard kit lens. These are usually lenses with a focal length between 15–55mm and are ideal for practicing and learning the basics.
If you have a camera without a standard zoom lens, or if you’re ready for the next step, a zoom lens is definitely worth considering. It opens up a wide range of photographic possibilities thanks to its versatility in focal lengths. In many cases, a single zoom lens is all you need. When you go out for a day of shooting, you won’t have to carry multiple heavy lenses with you.
Zoom lenses are also essential for certain types of photography, such as action, sports, and wildlife photography. These may seem like obvious use cases, but they are also commonly used in event and wedding photography. In these situations, you need to react quickly and don’t always have the option to physically move closer to the action.
If you’re planning to buy a zoom lens, it’s important to think in advance about the specific type of photography you want to use it for.
What should I consider when buying a zoom lens?
The most important thing to consider when choosing a zoom lens is the purpose you want to use it for. This largely determines which focal length you need.
In the overview below, we’ve listed the different focal lengths and explained what they are best suited for.
| Focal length | Explanation |
|---|---|
| 14–24mm | A wide-angle zoom lens, ideal for capturing landscapes and large spaces. |
| 18–55mm | A versatile all-round zoom lens for landscapes, snapshots, and travel. |
| 24–105mm | A flexible zoom lens suitable for many situations; ideal if you want to carry just one lens. |
| 24–70mm | Commonly used for weddings, portraits, and events. |
| 70–200mm | Popular for sports, wildlife, and portrait photography with strong subject compression. |
| 100–400mm | Ideal for sports and wildlife photography with long reach. |
| 150–600mm | Perfect for birds, wildlife, and distant action shots. |
Besides focal length, it’s also important to consider weight, size, and maximum aperture.
Even though lenses are becoming more compact, it’s still wise to take weight and size into account—especially if you’re often out shooting and need to carry your gear for long periods.
If you frequently photograph events or weddings, you’ll often find yourself working in low-light environments. In that case, it’s important to pay close attention to the lens’s maximum aperture. A zoom lens with a large maximum aperture is usually more expensive, but if you use the lens often, it can definitely be worth the investment.
