Focus peaking is a camera feature that adds colored outlines to the sharpest edges in the live view image, so you can see what is in focus while turning the focus ring. It is very useful for landscapes, where you often focus manually on a tripod. The steps below are general and the menu names differ between brands.
How Focus Peaking Works
The camera looks for areas of high contrast between neighboring pixels. When an edge becomes crisp, it draws a colored overlay on it, usually red, yellow, white or blue. As you move the focus ring, the overlay shifts to the parts of the scene that are sharp.
- It is available on many mirrorless cameras and some DSLRs in live view.
- You can often choose the color and the sensitivity level.
- It shows contrast, not true accuracy, so confirm with a zoomed view.
Setting It Up
- Open the menu and look for a setting called focus peaking, peaking level or MF assist.
- Turn it on and choose a color that contrasts with your scene, such as red on green foliage or yellow on a dark sky.
- Pick a level: low is more precise and high is easier to see.
- Switch the lens or camera to manual focus.
Using It for Landscapes
- Mount the camera on a tripod and compose the shot.
- Choose an aperture around f/8 to f/11 as a general guide for good depth of field.
- Decide on the point of focus, often about one third into the scene or on the nearest key subject.
- Turn the focus ring until the overlay appears on that point.
- Magnify the live view image and fine tune for the cleanest edge.
- Take a test shot and zoom into the playback to confirm.
| Problem | What to try |
|---|---|
| Overlay hard to see | Change the color |
| Too many highlights | Lower the level |
| Dim scene | Raise the screen brightness or use a longer exposure setting |
| Wind moving leaves | Focus on rocks or fixed objects |
Limits To Remember
Peaking can light up textured areas that are not truly sharp, and it may be unreliable in low light or with flat, low contrast surfaces. For night scenes, combine it with magnified live view on a bright, fixed landmark or a distant light.
FAQ
Does focus peaking change the photo?
No. The overlay shows only on the screen and is not saved in the image file.
Can I use it with autofocus lenses?
Yes, once you switch to manual focus or use manual override in the menu.
The Short Version
Focus peaking outlines sharp edges so manual focus is easier. Turn it on, choose a clear color, focus on a fixed point in the scene and verify with a magnified view or a test shot.
