At present, some of the mainstream camera phones outperform the first-generation digital single-lens reflex (DSLR) cameras in certain aspects, but from the perspective of professional photography
they are still far inferior to DSLRs. I will briefly analyze the respective advantages and disadvantages of the Huawei P30 and DSLRs from the following aspects:
1. Image quality. The sensor of the Huawei P30 is 1/1.7 inches, which is relatively large among mobile phones. Currently, mainstream compact digital cameras all use 1-inch sensors, not to mention APS-C and full-frame sensors. No matter how high the pixel count is, the image quality will not be good without a large sensor. In this regard, DSLRs completely outperform mobile phones. A larger sensor can deliver higher image quality. Even when zooming in on the original photos taken by both devices on a small mobile phone screen, you can intuitively see that the photos taken by a DSLR are much clearer. Although the ISO of the P30 Pro can reach 409600, allowing it to shoot clear objects in extremely dark environments (this really impresses me with the manufacturer's technology), when the same parameters are used, the image quality is still far inferior to that of a DSLR. However, it is still better than most compact cameras!
2. Color. Several current high-end Huawei phones cooperate with Leica, and they do a really good job in color tuning, allowing most ordinary users to easily take eye-pleasing photos, and they can even capture a hint of the "German style" feeling. The straight-out photos from DSLRs may not look as good as those taken by mobile phones for most cases, but RAW-format photos from DSLRs have enough room for post-processing (Huawei phones can also shoot in RAW format, but they are still far worse than DSLRs). Although it takes much longer to get a good work than using a mobile phone, the final effect is qualitatively different!
3. Lens. The P30 Pro has 50x digital zoom (10x is still usable, while 50x only offers convenience, and the photo quality is definitely mediocre). Any ordinary zoom lens for a DSLR definitely produces better image quality than that of a mobile phone, the only downside is that changing lenses is a bit cumbersome. In terms of aperture, the P30 can simulate a large aperture of f/0.95, but its bokeh effect is definitely not as natural as that of a DSLR. However, the bokeh effect achieved by current mobile phones is already quite good.
4. Portability. In this aspect, the P30 wins completely. You can take a small mobile phone out of your pocket and shoot photos of various subjects with wide angle, large aperture, telephoto and other effects. The key point is that a casual shot can still look so good, while a DSLR usually requires you to carry a bulky bag. After shooting, you may also need to sit in front of a computer and do slow post-processing.
Summary: Do not talk about surpassing in general terms. Mobile phones will never surpass DSLRs, as both mobile phones and cameras are developing. First of all, the sensor of a DSLR, the materials of high-quality lenses, large aperture, and optical zoom can never all be stacked into a mobile phone. Second, their application scenarios are different. For example, many functions of mobile phones and tablets have already surpassed those of desktop computers. Have you seen PCs being eliminated? For simply surfing the Internet, playing games, and multimedia entertainment, mobile phones and tablets are enough, and PCs can be left unused. But for office work, professional drawing, industrial design and many other industries, PCs cannot be replaced for the time being. Similarly, for daily shooting, taking photos of people and scenery during travel, and even even news photos, mobile phones have already performed extremely well. They do not require post-processing either, as they have advanced automatic algorithms. Just like the effect produced by my P20 Pro, it has really amazed many people. But for places with higher imaging requirements and many professional fields that require professional photography, the output of mobile phones is still far from sufficient.
Professional DSLRs are not designed for general application scenarios. Furthermore, different people have different requirements. Just like a few hundred yuan multimedia speakers and headphones can be used for listening to music in daily life, but what about theater stages, professional recording studios, and music enthusiasts? Right? In short, they have different uses, and neither can replace the other. Use a mobile phone for shooting when it is sufficient for your needs. If what a mobile phone can achieve meets your demand, there is no need to carry a big bag of entry-level DSLR just to show off. When mobile phones are not sufficient, you should still use the big equipment.
