What is an ultra-wide angle lens? What type of effects do ultra-wides produce? And should you use them in your photography?

I’ve been working with ultra-wide angle lenses for well over 30 years, and in my view, they’re incredible. They offer plenty of practical benefits, they’re a great way to improve your photography, and they’re lots of fun to shoot with, too.

In this article, I explain everything you need to know about ultra-wides, including what they are and why I highly recommend them. I also include plenty of examples, so you know exactly what ultra-wide lenses can do.

Let’s dive right in!

What are ultra-wide angle lenses?

Ultra-wide angle lenses are extreme versions of wide-angle lenses. Instead of producing a field of view that’s subtly wider than the human eye, they offer a field of view that’s far wider. They create a beautifully expansive effect:

Notice how, in the photo above, I’ve managed to capture over half of the room. That’s the power of an ultra-wide lens!

So what focal lengths correspond to ultra-wides?

Well, as you may already be aware, a 50mm lens (on a full-frame camera) closely approximates the field of view of the human eye. And wide-angle lenses feature smaller focal lengths, generally from around 24mm to 49mm.

Therefore, ultra-wide angle lenses have focal lengths that are wider than 24mm. A 10-20mm lens, for instance, is an ultra-wide zoom, while a 14mm lens is an ultra-wide prime.

(Note that these focal lengths are approximate; there’s no single agreed-upon set of focal lengths for wide and ultra-wide lenses.)

Take a look at this image, which is taken with a wide-angle (28mm) lens:

Then see how an ultra-wide focal length (11mm) widens the scene even further:

So while wide-angle lenses and ultra-wide angle lenses have a broad field of view, the ultra-wide effect is much more extreme.

When should you use an ultra-wide angle lens?

Ultra-wide lenses are hugely helpful, but you don’t want to use them all the time. For instance, trying to shoot a distant bird with an ultra-wide lens will get you nothing but a landscape and a distant blotch of feathers.

On the other hand, you can use ultra-wide lenses to capture entire scenes in a single shot. For instance, you can photograph an entire city skyline from end to end. Or you can photograph a beautiful mountain scene and include a foreground, a middleground, and plenty of mountain background.

Here are a few genres where ultra-wides are useful:

And here are a few genres where you should generally avoid ultra-wides:

Of course, you don’t need to follow this breakdown to the letter; it’s just a guideline. But it can be helpful, especially when you’re just starting out!

6 reasons to use ultra-wide angle lenses

In this next section, I share my six top reasons to work with ultra-wides. By the time you’re finished reading, I guarantee you’ll want to work with an ultra-wide angle lens or two in your own photography!

1. Ultra-wides immerse the viewer in the scene

Ultra-wide angle lenses draw the viewer into the situation.

They surround the viewer with the scene, and for that reason, the resulting shots feel stunningly real and full of detail.

And ultra-wides don’t just immerse the viewer in the scene; they immerse you, the photographer, which can be a wild experience.

As you shoot, you’ll feel like the entire scene is wrapping around your head. You’ll be pulled into the action, which is a great place to be!

2. Ultra-wides help you avoid perspective distortion

Perspective distortion causes vertical lines to converge, and it’ll even make buildings look like they’re falling backward. While it’s possible to fix distortion in post-processing, it’s much more efficient to avoid it in the first place – and ultra-wides can help you out.

You see, perspective distortion is produced when you tilt your camera downward or upward to photograph a scene. For instance, you might point your camera up to photograph a cathedral like this one:

And it’s that movement – that tilt up – that results in distortion.

But ultra-wide lenses are so wide that you often don’t need to tilt the camera when capturing a building. Instead, you can point the camera straight ahead and just…shoot. You’ll avoid distortion, and you’ll get a beautiful architectural image.

3. Ultra-wides reverse scale

Ultra-wide lenses tend to make objects that are close to the lens look enormous, while they make objects that are farther away look tiny. The wider the lens, the greater the effect!

(This is another consequence of perspective distortion, which I discussed in the previous section.)

While such distortion isn’t always desirable, it can look stunning when carefully incorporated into your photos. You can use it to magnify interesting foreground subjects:

Or you can use it to enhance visual flow:

4. Ultra-wides can create pseudo-panoramas

A panorama encompasses a huge portion of the scene and is generally far longer than it is tall, like this:

Unfortunately, panoramas are difficult to do well. You generally need to work on a tripod and take multiple images while carefully moving your camera. Plus, panoramas require significant post-processing.

But with an ultra-wide lens, you can create handheld panoramas with very little effort. Here’s what you do:

First, capture an image using an ultra-wide focal length:

Then open it in your favorite post-processing program and slice off the top and bottom of the frame:

That’s all there is to it! You’ll end up with a stunning panorama, and you won’t need to learn any additional techniques to get it right.

5. Ultra-wides are great for reflection shots

Do you love working with reflections? Do you want to take photos that feature expansive reflections, like the one displayed below?

Then use an ultra-wide angle lens! They’re so wide that you can easily include puddles, lakes, and reflective metal in every scene. Just make sure you get as close to the reflection as possible – don’t be afraid to place your camera on the ground – then shoot away.

6. Ultra-wides include so much detail

Every ultra-wide lens includes a huge field of view…

…and thanks to the huge field of view, you can include nearly everything in a single shot.

If you want to photograph a beach landscape, you won’t just get the water and the sky. You’ll get the sand, the rocks, the people on the beach, and maybe even your own feet.

And if you want to photograph a cathedral, you won’t just get the artwork on the ceiling or the stained-glass windows in the distance. Instead, you’ll get everything, from the ceiling and the pews to the windows and the walls. Ultra-wides are wide!

Capturing entire scenes isn’t always desirable, but when you encounter a sweeping scene that takes your breath away, you’ll be glad you had your ultra-wide angle lens!

Ultra-wide angle lenses: final words

Now that you’ve finished this article, you know all about ultra-wides. You know what they are, when you should use them, and what makes them so special.

So grab an ultra-wide angle lens. Head outside, practice, and have plenty of fun!
