Simply put, a blurry photograph is not crisp or sharp. While professional photographers may intentionally want to achieve a creative blurry image, most amateur photographers find it hard to understand why their images end up hazy.
So, if you have all the right equipment and an image still isn’t as clear as you’d hoped, something has gone very wrong. This article will help you figure out what went wrong and offer up solutions to help you get back on track in no time.

Causes and Solutions of Blurry DSLR Lenses
1. A Dirty Lens
There are a few things that can cause a blurry DSLR camera lens, but the most common culprit is simply dirty lenses. Dust, fingerprints, and even smudges from your clothing can all lead to lens blur. Luckily, cleaning your lenses and getting them back to looking their best is easy.
Clean your lens:
- Start by gently wiping the lens with a soft, clean cloth. If there is any dirt or debris on the lens, this will remove it.
- If the cloth doesn’t seem to be doing the trick, try using a LensPen or another type of lens cleaner designed specifically for cameras.
- Once you’ve cleaned the outside of the lens, look at the inside of the camera body to see if there is any dirt or debris build-up there. If so, use a blower brush or compressed air to remove it gently.
- If your lenses are still blurry after cleaning both the outside and inside of the camera, they may just be scratched up from use. In this case, you’ll need to buy new lenses (or have them professionally cleaned).
If your lens is clean and the images are still blurry, there are a few other things you can try:
2. Poor Focus
You might not be focusing on the right region of the image, which could also explain why your photos are turning out fuzzy. Using the proper focus mode on your camera can guarantee pin-sharp results every time.
Your camera’s autofocus system detects which parts of a subject should be in focus based on how close it is to your lens. Focusing your lens manually allows for more control over the focal points on your image, as opposed to using an autofocus system.
If you’re getting blurry photographs in either focus setting, it may be because your camera can’t see what you want it to concentrate on, so it focuses on surrounding items.
Adjust the focus ring:
You can try adjusting the focus ring on your lens. If your camera has an autofocus feature, it may be trying to focus on something in the background instead of what you are trying to capture.
You can override this by adjusting the focus ring on your lens until the subject comes into focus. If it doesn’t work, switch to manual focus and see if that makes a difference.

3. Camera Shake
What we call “camera shakes” are motions that cause the camera to shake while taking a photo. If your camera moves when you take the photo, it causes blurriness.
Preventing camera shake from blurring your photos requires a shutter speed that is at least as fast as the focal length. Setting your shutter speed at or above the focal length will help prevent camera shake-induced blur in your images. For instance, if you are taking photographs with a focal length of 100 millimeters, the minimum shutter speed you should use is 1/100.
Use image stabilization:
Image stabilization is a function of your camera that helps to reduce blurriness in photos. It does this by compensating for camera shake, which can happen when you’re hand-holding the camera or if the camera is moving around on a tripod.
To use image stabilization, simply turn it on in your camera’s menu. Once it’s enabled, you should notice a difference in the sharpness of your photos.
Use a shutter release:
If you’re using a DSLR camera, one way to avoid blurriness is to use a shutter release. This will allow you to take the photo without touching the camera, eliminating the possibility of shaking. There are two main types of shutter release – wired and wireless.
Wired shutter releases are typically less expensive, but they can be a bit more cumbersome to use. Wireless shutter releases offer the convenience of not worrying about a cord, but they may be slightly more expensive.
To use a shutter release, simply attach it to your camera and press the button to take the photo.
4. Motion Blur
Motion blur occurs when objects in the scene move during exposure. It happens when the shutter speed is too low, and you can notice the movement of your subject.
Use a higher ISO setting:
Try using a higher ISO setting. This will make your camera more light-sensitive, which can help reduce blurriness. Just be aware that using a higher ISO can also introduce noise into your photos.
Use a wider aperture:
Another way to introduce more light to your DSLR camera lens to reduce motion blur is to use a wider aperture. To do this, you’ll need to set your camera to aperture priority mode (A or Av on most cameras) and then choose a lower f-stop number.
For example, if you’re using a 50mm lens with an f/4 maximum aperture, switching to f/2.8 will double the amount of light that enters the camera. Just be aware that using a wider aperture will also decrease the depth of field, so it’s not ideal for every situation.
What preventative measures can you take to avoid a blurry DSLR camera lens?
Here are five simple steps you can take to avoid a blurry DSLR camera lens:
- Always keep your lens clean. Wipe it down with a soft, dry cloth after every use.
- Be careful when changing lenses. Eject the old lens carefully and line up the new one before attaching it.
- Avoid using your camera in extreme cold or heat. If you have to, keep it in a case to protect it from the elements.
- Don’t leave your camera in direct sunlight for too long. The sun can damage your camera’s internal components, causing blurred images.
- If you’re using a zoom lens, avoid extending it too far. Extending the zoom too far can cause the lens to become unbalanced and produce blurry images.
Conclusion
To recap, there are a few common causes of a blurry DSLR camera lens. The first is when the lens is not properly attached to the camera. Ensure you hear a “click” when you attach the lens to the camera body. If not, the connection is not secure and will result in a blurry image.
Another cause of blurriness is when your hands shake as you take the picture. To avoid this, use a tripod or lean against a solid object to steady your hands and camera. You can also set your shutter speed to 1/500th of a second or faster to prevent blurriness from shaking hands.
If you’re still having trouble with blurry images, it may be due to a dirty lens. Dust, dirt, and fingerprints can all affect the sharpness of your photos. Clean your lens with a microfiber cloth before each use. For stubborn dirt, you can use LensPen Lens Cleaner which safely removes fingerprints and grime without scratching the lens surface.
