The ultra-wide lens expands the field of view to fit more into the frame, while the telephoto lens optically zooms in to bring distant subjects closer. Both complement the main camera for different use cases.

Ultra-Wide Angle: Definition & explanation
In a nutshell
An ultra-wide lens captures a much larger field of view (typically 110–130°) than a standard camera. It's ideal for landscapes, architecture, and group shots in tight spaces.
How does Ultra-Wide Angle work?
Ultra-wide cameras use a short focal length to fit more scene content onto the sensor than a standard lens. Smartphones typically add a separate lens with a smaller sensor and lower megapixel count, often lacking optical zoom or autofocus. Typical field of view ranges from 110° to 130°, compared to roughly 70–80° on the main camera. The short focal length causes characteristic edge distortion, which software partially corrects. Modern systems also align color, sharpness, and exposure between the main and ultra-wide cameras so zoom transitions look seamless. Because less light hits each pixel and sensors are often smaller, low-light image quality is usually weaker than the main camera. Ultra-wide is mainly used for landscapes, architecture, interiors, and creative perspectives with exaggerated depth. On some devices, combined with macro mode, it also enables close-up shots at short focus distances.
Advantages of Ultra-Wide Angle
- Wider view without stepping back
- Great for landscapes and architecture
- Fits more people in tight spaces
- Enables creative, exaggerated-depth shots
Disadvantages of Ultra-Wide Angle
- Edge distortion at short focal lengths
- Usually weaker low-light performance
- Often lower megapixel count than main camera
- Rarely equipped with autofocus
Frequently asked questions
Manufacturers typically use smaller sensors with fewer megapixels for ultra-wide cameras to save space and cost. Additionally, the short focal length increases edge distortion and reduces light gathering in low-light conditions.
Some smartphones repurpose the ultra-wide camera for macro mode since it often allows a short minimum focus distance. Image quality is usually lower than with a dedicated macro camera with higher resolution.
