Where to find the shutter speed dial on your Canon

On most Canon DSLRs and mirrorless cameras, you change shutter speed using the mode dial on top of the camera body and the main dial (the textured wheel on the back right). First, rotate the mode dial to S (Shutter Priority) or M (Manual). In S mode, the camera picks the aperture for you once you set the shutter speed. In M mode, you control both shutter speed and aperture yourself.

Once you are in S or M mode, use your thumb to turn the main dial on the back of the camera. Each click changes the shutter speed by one stop. The shutter speed appears in the viewfinder and on the LCD screen on the back. On entry-level Canons like the T7 or T8i, the main dial is the only wheel you need. On professional models like the 5D or R5, there is also a sub-dial on the front, but the main dial on the back is the standard control.

Key Takeaways

  • Set your mode dial to S (Shutter Priority) to change shutter speed while the camera handles aperture, or M (Manual) to control both shutter speed and aperture yourself.
  • Turn the main dial on the back right of the camera to adjust shutter speed; each click moves you one stop faster or slower.
  • Shutter speed ranges from 1/4000 of a second (or faster on newer models) down to 30 seconds, plus Bulb mode for exposures longer than 30 seconds.
  • Faster shutter speeds (1/1000 and above) freeze motion; slower speeds (1/30 and below) create motion blur and require a tripod to avoid camera shake.

Understanding shutter speed numbers and what they mean

Shutter speed is measured in fractions of a second or whole seconds. A speed of 1/1000 means the shutter opens and closes in one-thousandth of a second. A speed of 2 means two full seconds. The LCD screen and viewfinder show these as numbers: 1000, 500, 250, 125, 60, 30, 15, 8, 4, 2, 1, and then whole seconds like 1", 2", 4", and so on.

Each step on the dial is one stop, which means the light entering the camera doubles or halves. If you turn the dial one click toward faster speeds, you go from 1/125 to 1/250 — half the light. One click toward slower speeds goes from 1/125 to 1/60 — double the light. This matters because faster shutter speeds need brighter light or a higher ISO to avoid underexposure.

Shutter speed for freezing motion versus creating blur

Use fast shutter speeds (1/500 and faster) to freeze action: sports, wildlife, children playing, or anything moving quickly. At 1/1000 or 1/2000, even fast motion appears completely still. At 1/250, most everyday movement freezes, but very fast action like a running dog or a bird in flight may show slight blur.

Use slow shutter speeds (1/30 and slower) to capture motion blur intentionally: flowing water, car light trails, or a sense of movement. Speeds of 1 second or longer require a tripod, because even small hand movements will blur the entire image. If you hand-hold the camera, the rule of thumb is to use a shutter speed no slower than 1 divided by your focal length — so at 50mm, do not go slower than 1/50 of a second.

How shutter speed interacts with aperture and ISO

Shutter speed, aperture, and ISO together control how bright or dark your image is. If you are in S mode and you slow down the shutter speed to let in more light, the camera automatically opens the aperture wider. If the aperture is already at its widest (the smallest f-number your lens allows), the camera cannot compensate further, and your image will be underexposed.

If you are in M mode, you control all three. Slowing the shutter speed lets in more light, so you may need to close the aperture (use a higher f-number) or lower the ISO to avoid overexposure. Speeding up the shutter lets in less light, so you may need to open the aperture or raise the ISO. Learning to balance these three is the foundation of manual exposure control.

Using Bulb mode for long exposures

If you need an exposure longer than 30 seconds, switch to Bulb mode. In M mode, turn the main dial past 30" and you will see "Bulb" appear on the screen. In Bulb mode, the shutter stays open as long as you hold down the shutter button. Release the button and the shutter closes.

Bulb mode is used for night sky photography, light painting, and other long exposures. Because you cannot hold the button for minutes without moving the camera, use a remote shutter release or the camera's self-timer to avoid shake. Set the camera on a tripod, compose your shot, and either press the remote or set the self-timer to 2 or 10 seconds before the exposure begins.

Common mistakes when changing shutter speed

The most common mistake is forgetting to switch out of P (Program) or A (Aperture Priority) mode. In P mode, the camera controls both shutter speed and aperture, so turning the dial does nothing. In A mode, the dial controls aperture, not shutter speed. Always check the mode dial on top of the camera to confirm you are in S or M before you try to adjust shutter speed.

Another mistake is using a shutter speed that is too slow while hand-holding the camera. If your image looks soft or blurry overall (not just the moving subject), camera shake is the cause. Increase the shutter speed, raise the ISO, or use a tripod. A third mistake is forgetting that in S mode, the camera may not be able to maintain your chosen shutter speed if the light is too dim or too bright. If the aperture display blinks in the viewfinder, the exposure cannot be achieved with your current shutter speed and ISO.

Frequently Asked Questions

What shutter speed should I use for everyday photography?

For most daylight photography outdoors, 1/125 to 1/500 works well. Indoors or in dim light, you may need 1/30 to 1/60, but use a tripod or brace the camera to avoid blur. Start with 1/125 and adjust based on whether your images are too bright or too dark.

Why does my image look blurry even though I used a fast shutter speed?

If the subject is sharp but the whole image is soft, you have camera shake — you moved the camera while the shutter was open. Use a faster shutter speed, raise the ISO, or use a tripod. If only the subject is blurry, your focus was off or the subject moved faster than your shutter speed could freeze.

Can I change shutter speed while recording video?

No. On Canon DSLRs and mirrorless cameras, shutter speed is locked during video recording. You control exposure with aperture and ISO only. Some newer Canon mirrorless models allow you to adjust shutter speed in certain video modes, but this is not standard.

What is the fastest shutter speed my Canon can use?

Most Canon DSLRs max out at 1/4000 of a second. Professional models like the 1D X series reach 1/8000. Newer mirrorless cameras like the R5 and R6 can go to 1/8000 or faster. Check your camera manual for the exact maximum.

Do I need to change shutter speed if I am using autofocus?

Autofocus and shutter speed are separate. Autofocus finds the subject and focuses the lens; shutter speed controls how long the sensor is exposed to light. You need to set shutter speed based on how much light you have and whether you want to freeze or blur motion, regardless of whether you use autofocus.
