An affordable choice for most DSLR models and brands is a 50 mm lens with an aperture of f1.8. However, for the best blur effect, consider buying a lens with a large aperture (smaller f-values), often sold as low-light or fast lenses. You can achieve blurred backgrounds by zooming in and keeping your subject close to you but far away from the background. Kit lenses that are sold with most consumer-grade DSLR cameras have small apertures (f4 to f8). Cameras with larger sensors can achieve longer focal lengths and subsequently better background blur.

Sensor size: A small sensor has a short focal length and wide angle of view.

To blur the background, use a long focal-length lens or a good variable-focus-length lens and zoom in on your subject. Zooming in on a subject narrows the angle of view and makes the focal length longer, resulting in more background blur.

Focal length: A short focal length has a wide angle of view which keeps details in focus both in the foreground and the background.

Distance from your subject: Moving closer to and focusing tightly on your subject and ensuring the background is far away from your subject make it easier to achieve a blurred background.

The lower the f-value, the softer the background blur. When using a large aperture, the shutter speed should be faster to prevent the photo from being over-exposed. Larger apertures have smaller f-values and allow more light to reach the camera sensor.

Aperture: Specified by an f-value or f-stops.

The following aspects majorly affect the blurriness of background clutter:
