Shutter speed is one of the most important exposure settings on a mirrorless camera, and knowing how to change it quickly can improve both still photos and video.
This guide explains where to find the setting, how it affects your images, and how to avoid common mistakes when shooting in real-world conditions.
What shutter speed does on a mirrorless camera
Shutter speed is the length of time the camera sensor is exposed to light.
On mirrorless cameras from brands like Sony, Canon, Nikon, Fujifilm, Panasonic, and OM System, it is usually shown as a fraction such as 1/250, 1/60, or 1/2000.
A faster shutter speed lets in less light and freezes motion more effectively.
A slower shutter speed lets in more light and can create motion blur, which is useful for creative effects or low-light shooting.
- Fast shutter speeds: reduce blur from movement and camera shake
- Slow shutter speeds: brighten the image and can blur moving subjects
- Balanced settings: help you control exposure without raising ISO too much
How to change shutter speed on a mirrorless camera
The exact steps vary by model, but most mirrorless cameras use a control dial, command wheel, or touchscreen.
In many cases, you can change shutter speed directly in Manual mode, Shutter Priority mode, or some Auto modes with manual override.
Use the main control dial
On many mirrorless cameras, rotating the front or rear dial changes shutter speed once the camera is in a mode that allows direct control.
For example, in Manual mode, one dial may change shutter speed while another changes aperture.
If your camera is set to Shutter Priority, often labeled S or Tv, the camera automatically adjusts aperture while you set shutter speed.
This is one of the fastest ways to control motion.
Check the touchscreen or quick menu
Some mirrorless cameras let you tap the shutter speed value on the screen and then adjust it with a slider or dial.
This is common on compact models and newer cameras with touchscreen menus.
The quick menu may also include shutter speed settings, especially if your camera lets you customize frequently used controls.
Use exposure modes that support manual control
- Manual mode (M): you set shutter speed, aperture, and ISO
- Shutter Priority (S or Tv): you set shutter speed, and the camera sets aperture
- Aperture Priority (A or Av): shutter speed changes automatically, though some cameras allow limits or compensation
Where shutter speed is displayed
Mirrorless cameras usually show shutter speed in the electronic viewfinder, on the rear LCD, or both.
The value may appear as a clean fraction, a number like 125 for 1/125 second, or a long-exposure notation such as 2" for two seconds.
In bright conditions, the viewfinder can be easier to read than the rear screen.
If the display seems unclear, check your camera’s display settings, brightness options, or overlay style.
How to choose the right shutter speed
The best shutter speed depends on your subject, lens, and shooting style.
A portrait, a bird in flight, and a night street scene all require different settings.
For handheld photos
A common rule is to use a shutter speed at least as fast as the inverse of your focal length.
For example, with a 50mm lens, start around 1/50 or 1/60 second.
With a 200mm lens, a faster setting such as 1/250 or 1/320 is often safer.
Image stabilization, including in-body image stabilization (IBIS) and optical stabilization, can help reduce camera shake, but it does not stop subject movement.
For moving subjects
- Walking people: around 1/125 to 1/250
- Sports and action: 1/500 to 1/2000 or faster
- Birds and fast wildlife: often 1/1000 and above
If the subject is moving unpredictably, increase shutter speed first, then adjust ISO or aperture to maintain exposure.
For creative motion blur
Slow shutter speeds are useful for waterfalls, night traffic, long-exposure landscapes, and panning shots.
Common ranges include 1/30, 1/10, 1 second, or longer, depending on the effect you want.
For very slow speeds, use a tripod, remote shutter release, or self-timer to reduce camera movement.
How shutter speed affects exposure
Shutter speed is one part of the exposure triangle, along with aperture and ISO.
Changing shutter speed darker or brighter changes the amount of light reaching the sensor.
- Faster shutter speed: less light, darker image
- Slower shutter speed: more light, brighter image
- Higher ISO: brightens the image but may add noise
- Wider aperture: brightens the image but reduces depth of field
In strong daylight, very fast shutter speeds may be needed to prevent overexposure.
In low light, slower shutter speeds can help, but they increase the risk of blur if the camera or subject moves.
Common shutter speed settings on mirrorless cameras
Most mirrorless systems offer a broad range of shutter speeds, often from 1/8000 second to 30 seconds, plus bulb mode for even longer exposures.
High-end models may also support electronic shutter speeds that are useful for quiet shooting or fast bursts.
- 1/8000 to 1/2000: bright light, sports, fast action
- 1/1000 to 1/250: general action, portraits, casual handheld shooting
- 1/125 to 1/30: low-light handheld work, moderate motion blur risk
- 1/15 and slower: low light, intentional blur, tripod work
Electronic shutter versus mechanical shutter
Many mirrorless cameras let you choose between mechanical and electronic shutter options.
This affects how the camera captures the image, especially at fast speeds or during silent shooting.
Mechanical shutter
The mechanical shutter uses physical curtains and is often preferred for general photography because it is reliable and can reduce rolling-shutter distortion in some situations.
Electronic shutter
The electronic shutter reads the sensor without moving parts, which can make the camera silent.
However, it may cause rolling-shutter effects with fast-moving subjects or artificial lighting, depending on the model.
If your camera offers both, test each option with your typical subjects before relying on it for important work.
Problems that happen when changing shutter speed
New users often assume a faster shutter speed is always better, but that can cause underexposure or force ISO too high.
Others use a slow speed without stabilizing the camera, which causes blur.
- Image too dark: shutter speed is too fast for available light
- Blurred subject: shutter speed is too slow for the motion in the scene
- Camera shake: handheld shutter speed is too slow for the lens or shooting position
- Noise increases: ISO had to be raised to compensate for fast shutter speed
When this happens, adjust in this order: choose the shutter speed needed for motion, then open the aperture if possible, then raise ISO as needed.
How to set shutter speed for video on a mirrorless camera
Video uses a different approach from still photography.
A common guideline is the 180-degree shutter rule, which means using a shutter speed about double the frame rate.
For 24 fps, that is usually 1/50; for 30 fps, 1/60; for 60 fps, 1/125.
This helps motion look natural on screen.
If you need sharper motion for a stylized look, you can use a faster shutter speed, but the footage may appear more choppy.
Tips for changing shutter speed faster in the field
- Assign shutter speed to a custom dial or control wheel if your camera allows it
- Use Shutter Priority when motion is your main concern
- Set a minimum shutter speed in Auto ISO menus on supported cameras
- Save custom shooting modes for portraits, sports, and low-light scenes
- Learn where shutter speed appears in the viewfinder before you head out
Once you know how to change shutter speed on a mirrorless camera, you can react quickly to changing light and subject movement instead of missing the shot while digging through menus.
