Phone camera specifications that matter beyond megapixels
Compare main, ultrawide and telephoto results in real light, including focus, stabilisation and processing.
Start with the real use
Megapixels describe sampled resolution, not lens sharpness, sensor size, dynamic range or colour. Secondary cameras can be much weaker than the main module.
Understand the compromise
Heavy processing can brighten night scenes yet blur movement or textures. Digital zoom crops and reconstructs information; optical reach and sensor quality still shape detail.
Verify the exact product
Inspect full-resolution samples and video from the exact model, with faces, movement, indoor light and the zoom ranges you will use.
Before you decide
- Decision to record: Compare main, ultrawide and telephoto results in real light, including focus, stabilisation and processing.
- Comparison to make: Megapixels describe sampled resolution, not lens sharpness, sensor size, dynamic range or colour. Secondary cameras can be much weaker than the main module.
- Trade-off to accept: Heavy processing can brighten night scenes yet blur movement or textures. Digital zoom crops and reconstructs information; optical reach and sensor quality still shape detail.
- Evidence to verify: Inspect full-resolution samples and video from the exact model, with faces, movement, indoor light and the zoom ranges you will use.
Common questions
Do more megapixels guarantee more detail?
No. Lens, sensor, processing, light and stabilisation all matter.
Is every telephoto camera optical zoom?
Check the actual lens and sensor; some claimed zoom levels rely partly or entirely on cropping.
