When to Use Which Lens and Why
All camera systems offer a dizzying selection of lenses. These range from fisheye lenses that give a 180° field of view to telephoto lenses up to 800mm. Youâve got zooms, primes, macro lenses, super telephotos, tilt-shift lenses, and more.
So itâs not surprising that, in my time as a photographer, Iâve often had friends, students, or casual acquaintances ask me, âWhat lens should I get?â
There is no one right answer to this question â it all depends on you, how you like to shoot, and what you like to shoot.
Which is why Iâve written this article.
In it, Iâm going to give you a rundown of each type of lens. Iâll explain what the lens can do and when youâll want to use it.
By the time youâre done, youâll know the perfect lens for your needs.
Letâs dive right in.
Start with your subject and your budget
What lens should you use?
To answer this question, Iâd like to ask a few questions of my own.
The first question, and the easiest to figure out is, âWhat do you want to shoot?â
It could be sports, wildlife, birds, landscapes, architecture, portraits, or any number of other subjects.
Next, ask yourself:
âWhat is my budget?â
The cost of a lens depends on several things. Less expensive lenses will generally have variable apertures â so as you zoom, the maximum aperture gets smaller. More expensive lenses have a fixed aperture.
The good news is that all major camera and lens manufacturers offer a variety of focal lengths to satisfy most budgets.
After youâve answered those two questions, itâs time to take a look at the different types of lenses and how they can be used. As you read these next few sections, make sure to focus on what you plan to shoot!
Wide-angle lenses (10mm to 35mm)
In my early days as a photographer, I never used wide-angle lenses. I started my career as a sports photographer and rarely used anything shorter than 70-200mm (and I often went for 400mm f/2.8 lenses or 600mm f/4 lenses).
But then, as I began shooting landscapes, I discovered the magic of wide angles.
Wide angles give an expansive view, and when used correctly, they can wrap you in the scene. My favorite lenses for landscape work tend to be a 14mm f/2.8, a 16-35mm f/2.8, and a 24mm f/1.4.
If you shoot scenes with prominent foreground objects, then a wide-angle lens is the way to go. A major mistake made by new photographers is to use wide angles incorrectly; by not being close enough, having no interest in the foreground, or by trying to include too much in the scene, youâll end up with less impactful photos.
Wide angles are also handy in tight areas, like small rooms, cars, caves, etc. They can create volume and expansiveness in a limited space.
Which is why wide-angle lenses have the potential to drastically change your photography!
Standard lenses (35mm to 85mm)
Standard zoom lenses are great walkaround lenses. They are versatile, allowing you to do wide-angle landscape shooting, before zooming in to the telephoto end to take a great portrait.
In fact, standard zooms tend to cover moderate wide-angle focal lengths all the way down to a medium telephoto â they often start at 24mm to 35mm, then zoom to around 70mm or even 105mm.
Many kit lenses â lenses that come as part of a camera package â are standard zooms. However, there are also standard prime lenses.
What are standard primes?
Well, prime lenses offer just one focal length, such as 35mm, 50mm, or 85mm. So a standard prime falls somewhere in that 35mm to 85mm standard range.
In fact, back in the good old days of film, the most popular standard lens was a standard prime: the 50mm. When I was a student, everyone in the class started with a 50mm lens.
That said, whether you choose a zoom or a prime is up to you. Most people feel that zooms offer more bang for the buck these days. But a prime does force you to think more about composition and point of view, simply because it canât zoom. And prime lenses also tend to be cheaper than optically-equivalent zooms.
Telephoto lenses (85mm to 300mm)
Telephoto lenses get you close to a subject without actually approaching them. Working with a telephoto lens is like shooting through binoculars because they magnify distant subjects.
Now, more often than not, when I speak to new photographers looking to purchase their next lens, they want something on the telephoto end. The most popular telephotos seem to be various flavors of 70-300mm or 70-200mm.
These lenses are excellent when used properly. However, too often, telephoto zooms allow the photographer to become lazy.
âIf your pictures arenât good enough, youâre not close enough,â said famed war photographer Robert Capa. Telephoto zooms allow you to stand back when the subject isnât quite as approachable or when your subject might be feeling overwhelmed by the presence of the camera (e.g., candid street portraits). This makes telephoto zooms extremely useful for plenty of situations â but keep in mind Capaâs words, as it is easy to get lazy and let the lens do the work for you.
Telephoto lenses also compress distance, making everything appear closer together, as opposed to wide-angle lenses, which distort perspective and make things look separate.
This can be useful for landscapes when you want the sun or moon to appear large in comparison to other objects in the image. In this shot of the Shenandoah Valley at sunset, the telephoto lens compresses the scene, making the layers of mountains and mist look almost flat:
Of course, telephoto lenses are also excellent for sports, nature, and wildlife photography, where it can be difficult to get close. Sports, however, presents its own set of challenges. To be able to stop action without blur, you need a fast shutter speed. Typically, faster telephoto lenses are required.
A âfastâ lens is usually one that has an aperture of f/4, f/2.8, or larger. If sports is one of your primary subjects, a telephoto zoom such as a 70-200mm f/2.8 is an excellent choice. If you really want to shoot like the pros, youâll want a 300mm f/4, a 300mm f/2.8, or a 400mm f/2.8. These lenses are great for getting you closer to the action, but you need to be sure your shutter speed is fast enough!
Specialty lenses
Beyond the âconventionalâ lens types, there are a variety of specialty lenses available.
Do you like shooting tiny things? Try a macro lens.
Want to shoot architecture? A tilt-shift lens might do the trick.
In fact, there is a lens for every purpose; itâs just a matter of putting it to good use.
But always remember that a lens is just another tool on the camera. Itâs up to the photographer to make it work!
