Why is SLR camera better than mobile phone?

Mobile phone pixels surpass SLR, but the effect is still not as good as SLR, because the difference in photo quality is not just pixels. Color difference, dispersion, color fading, distortion and sharpness are all indicators to measure film quality.

The biggest difference between shooting mobile phones, DC and SLR lies in the different lenses and photosensitive devices used. The cheaper the photographic equipment, the cheaper the lens, and the worse the control of these indicators.

The same is true for photosensitive devices. The cheaper the photographic equipment, the smaller the size of the photosensitive device. Even if the photo collected optically is digitally enlarged by digital means such as interpolation, the photo is still blurred, because it is optically impossible to reach high pixels.

Under the same pixel, how different is the quality of photos taken by mobile phone, DC and SLR? Generally, mobile phones are compared with SLR, not to mention whether they can take pictures in extreme environments (such as dark or bright environments). Even in the general environment, the larger photosensitive device of SLR determines that its photos are clearer.

At the same time, because SLR can improve the color difference, dispersion, color attenuation and distortion and improve the definition by replacing expensive lenses, theoretically, SLR can take better photos than mobile phones.
