You’re familiar with the concept, even if you don’t realize it: When you photograph a scene, the objects closest to the lens look bigger than the objects off in the distance. That way, the depth of field keeps the ground and any landscape elements sharp from the foreground to infinity!Īll photos feature perspective. You simply tilt the lens down so the plane of focus is more closely aligned with the ground.

If you need a fast shutter speed and you’re working in low light, you may not have the option to shoot at a narrow aperture.Ī tilt-shift lens, however, can keep an entire shot sharp even with a shallow depth of field.

(Plus, once you get past f/13 or so, you’ll see a noticeable loss in sharpness due to diffraction.)

If the scene is too deep, your lens may not offer a sufficiently small aperture to achieve the depth of field effect that you need.

But while this method often works, you can run into two issues: The standard approach is to narrow your lens’s aperture until you have a depth of field so deep that both the foreground rock and the background mountain are sharp. You see, if you’re photographing a deep landscape scene – with a rock in the near foreground and a mountain in the distant background, say – you’ll generally want to keep the entire shot in focus. Second, you can use a tilt effect to keep your entire scene sharp – even with an insufficient depth of field. The resulting image can have all sorts of interesting effects: the left side of the scene can be in focus while the right side of the scene is blurred a subject in the right foreground area and the left background area can be in focus while the opposite areas (the left foreground and the right background) can be out of focus. Tilt-shift lenses, however, give you the ability to tilt the lens’s plane of focus so it’s not perfectly parallel to the image sensor. If you capture an image with a deep depth of field, you’ll have lots of sharpness beyond the plane of focus, and the background will turn out sharp.

If you capture an image with a shallow depth of field, you’ll have very little sharpness beyond the plane of focus and the background will turn out blurry. Think of this as a sharpness buffer around the plane of focus. (I say “far enough” because every image contains a depth of field. Any objects sitting far enough in front of the brick wall, however, will appear out of focus, as will any objects positioned far enough behind the brick wall. If you point a normal lens at a flat brick wall and focus it carefully, you’ll capture a photo with each and every brick in focus. Normal lenses are perfectly aligned with (i.e., parallel to) the image sensor, which means that the plane of focus is also aligned with the sensor. But how does this work?īecause the tilt effect and the shift effect are essentially unrelated, we can tackle them independently: The tilt effect

Of course, there are major advantages to utilizing a TS lens’s unique abilities, which I discuss in the next section: Tilt vs shift: What does a tilt-shift lens do?Īs mentioned above, tilt-shift lenses are designed to eliminate perspective distortion and offer powerful control over image depth of field. In other words, you can mount a TS lens to your DSLR or mirrorless camera and use it immediately as long as you don’t mess with the tilt and shift mechanisms, you’ll need zero additional knowledge or training. Note that tilt-shift lenses work like any other interchangeable lens – but with a few additional features. In particular, tilt-shift glass is frequently handled by landscape and especially architectural shooters, though other photographers (e.g., wedding, portrait, and even macro shooters) do use them to produce interesting creative effects. Offer expanded control over depth of field.A tilt-shift lens is a special optic designed to do two things:
