To remove a lens from your Canon camera, first turn the camera off. Press the lens release button, then rotate the lens counterclockwise until it detaches. Immediately cover the camera’s body opening and the rear lens element with caps to prevent dust ingress.
Swapping lenses is a fundamental part of photography, allowing you to adapt to different scenes and subjects. Whether you’re cleaning your gear, changing to a telephoto for wildlife, or storing your camera, doing it correctly protects your expensive equipment from dust, scratches, and costly damage to the lens mount.
This guide will walk you through the exact steps for both Canon DSLR (EF/EF-S mount) and newer mirrorless (RF/RF-S mount) cameras, highlight what tools you need, and cover common mistakes to avoid. Following this procedure ensures your camera and lenses stay in perfect working order for years.
What You’ll Need
- Your Canon camera
- The lens you wish to remove
- A clean, flat, and stable surface (like a table)
- Lens rear cap and body cap (should be with your camera/lens)
- A clean, dry environment, ideally indoors and away from wind, sand, or rain
- Optional: A camera strap for extra security
How to Remove a Lens From a Canon Camera, Step by Step
Step 1: Prepare Your Workspace and Camera
Find a clean, dry, and stable area to work. A table indoors is ideal. Turn your Canon camera OFF. This prevents the camera from attempting to activate the lens mechanism or autofocus during removal, which could cause issues. If your camera is on a tripod, remove it first for better control.
Have your lens rear cap and camera body cap within easy reach. We recommend doing this step quickly after the lens is off to minimize the time the sensor is exposed. If you’re wearing a camera strap, ensure it’s secure around your neck or wrist to prevent accidental drops.
Step 2: Locate and Press the Lens Release Button
Hold the camera body securely in your left hand, with the lens facing away from you. With your right hand, grip the lens barrel. Look for the lens release button on the camera body, near the lens mount. On most Canon DSLRs and mirrorless cameras, it’s a small, recessed button on the right side (when facing the camera).
Press and hold this button down. You should feel a slight click or give. Keep the button depressed for the entire rotation in the next step. This disengages the locking pin that secures the lens to the mount.
Step 3: Rotate the Lens to Unlock It
While continuing to hold the lens release button, gently rotate the lens. The direction is crucial. For all Canon EF, EF-S, RF, and RF-S mount lenses, you rotate the lens counterclockwise (when looking at the front of the camera).
Rotate only until the lens stops—this is usually about a quarter to a half turn. You will feel the lens become loose from the mount. Do not force it. If it doesn’t rotate easily, double-check that the release button is fully pressed and that the camera is powered off.
Step 4: Detach the Lens and Cap Immediately
Once unlocked, gently pull the lens straight back, away from the camera body. Avoid any tilting or wiggling, as this can scratch the lens mount contacts or the camera’s mirror/sensor area.
This is the most critical moment for preventing dust. As soon as the lens is free, use your left hand to place the camera body cap onto the camera mount. With your right hand, secure the rear lens cap onto the back of the lens. Do this swiftly but carefully.
Step 5: Store or Prepare the New Lens
Place the now-capped lens in a safe spot, such as in its bag or on a clean surface. If you are attaching a new lens, remove its rear cap first, then align the mounting index mark on the lens (usually a red or white dot/square) with the corresponding mark on the camera mount.
Insert the new lens straight into the mount and rotate it clockwise until it clicks securely into place. You do not need to press the release button for this. The click confirms the locking pin has engaged. For more detailed maintenance, you can read our guide on how to clean inside a canon lens.

Common Mistakes to Avoid
- Removing the lens with the camera on: Always power down first to protect the electronic contacts and mechanisms.
- Forgetting to press the release button: Trying to rotate the lens without pressing the button can damage the locking mechanism.
- Rotating the lens the wrong way: Canon lenses unlock counterclockwise. Forcing them clockwise can break the mount.
- Tilting the lens during removal: Always pull the lens straight back to avoid scratching the mount or sensor.
- Leaving the body or lens uncapped: Even a few seconds of exposure invites dust onto your sensor or lens elements.
- Changing lenses in a dirty environment: Avoid doing this on a windy beach, dusty trail, or in the rain.
Frequently Asked Questions
Which way do you turn a Canon lens to remove it?
To remove a lens from a Canon camera, you turn it counterclockwise (when facing the front of the camera). This applies to all modern Canon lens mounts including EF, EF-S, RF, and RF-S. Remember to press and hold the lens release button while turning.
Is it bad to change camera lenses often?
Changing lenses is a normal part of photography and will not harm your camera if done correctly. The key is to follow the proper procedure (turning off the camera, working in a clean environment, capping immediately) to prevent dust from entering the camera body and settling on the sensor.
Why wonu0026#039;t my Canon lens come off?
If your lens won’t detach, first ensure the camera is off. Then, check that you are fully pressing the lens release button and rotating the lens counterclockwise. If it’s still stuck, do not force it. Consult your camera’s manual, as some models may have a secondary lock, or contact Canon support.
Should you store a camera with or without a lens?
You should store your camera with a lens or a body cap attached at all times. Storing it without a cap leaves the sensor and internal components exposed to dust and potential damage. If storing long-term, attaching a lens (with caps on both ends) or a dedicated body cap provides the best protection.
Can I use my old Canon EF lenses on a new mirrorless camera?
Yes, you can use Canon EF and EF-S lenses on Canon’s RF-mount mirrorless cameras like the u003ca href=u0022https://www.amazon.com/dp/B0FGKCDGCZu0022u003eCanon EOS R50 V Mirrorless Camera with 14-30mmu003c/au003e by using an official Canon Mount Adapter.
