Who makes the best mobile cameras on the market? Sony. Or at least it is logical if we consider that the Sony Xperia Z5 has the best camera on the market, and that it is responsible for manufacturing the sensor of the iPhone 6s, another of the phones with the best camera on the market. Its latest Sony Xperia Z5 in the different versions have come with a 23 megapixel camera, an improvement over the 21 megapixel cameras of previous Sony flagships. How, then, is it possible that talking about a 12-megapixel camera can be better than a 16-megapixel camera, or even a 23-megapixel camera?
Until now, the Nexus were mobiles that had high-level technical characteristics, and a rather economical price. This is the case with the latest Nexus 5X and Nexus 6P. However, the latter are different for something. Unlike the previous Nexus, these have a high quality camera. Coincidentally, it is a 12 megapixel camera, like the iPhone 6s, and like the one that would be present in the Samsung Galaxy S7. A camera considered one of the best on the market.
To get good photos there is a key and unique element. In fact, it is a determining element in any photographs. And it is light. You will never get a good picture without enough light. At the same time, that the camera is able to capture the light is also key. The big problem with mobiles is that they have cameras that are very small compared to DSLR or even CSC equipment cameras, which have APS-C sensors or Full Frame sensors. Logically, for mobiles it is impossible to compete in quality with these high-level cameras, because they have very small sensors, despite the fact that the Sony Xperia Z5 camera, for example, has a higher resolution than the Nikon D5, the highest level of Nikon. In other words, the photos captured by the Sony Xperia Z5 have more pixels than the photos from a Nikon D5, a camera priced at 7,000 euros. 23 megapixels vs 20.8 megapixels. And a demonstration of something clear: using resolution as the only reference to assess the level of a camera is complete stupidity.
Based on that, it is not difficult to understand that it is possible that a camera with a 12 megapixel sensor is better than a camera with a 16 megapixel sensor. But why? That is the question.
Because the pixels are bigger. It is simple. We need to capture more light to capture better photos. But the basic problem is that the sensor has a very small size, that of a mobile camera. We can’t get bigger sensors, because that would mean bigger lenses, and cameras that take up more space on the smartphone itself. And there is no room for mobile phones. Today, the sensors that exist are those that exist. And yes, the sensors of the mobile cameras are getting bigger, it will also be a novelty in the Samsung Galaxy S7, but the difference would not be really noticeable if it weren’t for the fact that 4 megapixels are going to be eliminated. That said so is little, but that in reality it means removing 4 million pixels. Remove a quarter of the pixels. Get a slightly bigger sensor. For what? So that the photosensor pixels are larger, and therefore, capture more light.
Samsung has yet to officially present the Samsung Galaxy S7, confirm that the camera will be 12 megapixels, and give more details about the size of the sensor and the pixels, which will give them. And then you have to test the camera, analyze it and compare it with others like the Sony Xperia Z5. But in general, we can say that it is possible with a resolution of 12 megapixels to get better photos than with a 16 megapixel camera. The resolution is more even than what we are going to use in a professional photography, but the quality of the photo will be better. And who knows if it is a first step for mobile cameras to have an option to gradually take over from professional cameras, at least as regards the possibility of replacing professional compact cameras, or as a second or third camera for the higher level photographers.
