It's been 202 1 year, why is the picture quality of mobile phone not as good as that of camera?

After entering September, we will welcome the Mid-Autumn Festival holiday, and then the National Day holiday is not far from us.

During the holidays, many people choose to travel, and the scenery, cultural environment and local food along the way will inevitably be photographed, and then placed in a circle of friends or made into photo albums, which will become our precious memories.

But is it really enough to take pictures with your mobile phone?

To tell the truth, it's really not so good. Only the photos taken by the camera meet the requirements.

Why do you need a camera?

I believe some people will have questions. Nowadays, there are more and more mobile phone lenses and higher and higher pixels. Is the picture quality not as good as that of the camera?

That's true, because of their differences in physical hardware.

The core components of camera and mobile phone imaging system are CMOS image sensor and lens. Among them, the larger the area of CMOS image sensor, the more light it can receive, so the image quality will be better.

However, due to the portability of mobile phones, the body is getting thinner and thinner, which also limits the size of CMOS image sensors. At present, it is generally believed that CMOS at the bottom of 1 inch is the limit on mobile phones. Now the camera has easily realized Quan Huafu.

So how big is the difference between the two?

First of all, under the condition of keeping the same distance, lens focal length and fuselage height from the subject, the obtained pictures are obviously different in size.

Suppose that Quan Huafu is a whole picture, and an inch of land is a red box area. From the contrast in the picture, it can be seen that the photo with an inch bottom is more like a part of Quan Huafu's picture. Under the same conditions, the breadth and depth of Quan Huafu have gained innate advantages. If the mobile phone wants to get the same picture, it may need to take back the camera for tens of meters to solve it, and the camera has no such trouble.

In addition to the differences between framing images, the camera still maintains an absolute lead in core image quality. Then we compare them through several sets of photos.

All the photos were taken with the same parameters. It can be clearly seen from the comparison photos that the picture clarity of the bottom photo of 1 inch can't be compared with that of Quan Huafu, especially after entering high sensitivity, the noise generated by the picture makes the whole photo look very blurred. Although there is noise in Quan Huafu, the overall picture is clean and some details are clearly visible.

Therefore, the film quality of the camera is better than that of the mobile phone in details, high sensitivity, latitude, color and depth of field. Although mobile phones have advantages in imaging algorithms, the inherent deficiency of physical hardware still cannot make up for the gap between them. In addition, the camera can also change the lens. A lens with good performance can not only further expand the advantages of image quality, but also bring more expandability to the camera in use scenes and requirements, which is why photographers still prefer professional cameras.

It is said that fashion is a circle. In recent years, the retro trend has swept almost all fields, and cameras are no exception. Nikon Z fc micro-camera adopts retro appearance, paying tribute to Nikon classic mechanical camera FM2. The perfect combination of colorful leather and metal adds a touch of liveliness to the steady and classic tone. And the camera itself also supports official skinning. There are six different colors of leather to choose from, and different colors are used to express different fashion attitudes.

Many Xiaobai, who have just started to contact photography, often struggle between micro-single and SLR cameras when purchasing cameras. Micro-orders always seem to give people the impression of being "unprofessional". In fact, with the development of technology, the shortcomings of micro-cameras in professionalism have long been made up. Moreover, one of the advantages of micro-single compared with SLR is that it is light and compact. Nikon Z fc micro camera weighs only 445 grams, and it is light to take pictures when going out of the street, so it will not be a burden at all. With the blessing of fashion appearance, going out to sweep the street will definitely earn enough attention.

When Nikon introduced the Z fc, it specially designed a lens with the same retro characteristics for this camera, namely the Nico Z 28mm f/2.8(SE). It is not only light and compact, but also sensitive to focus and can quickly lock the subject. Beautiful moments are always fleeting, and accurate and fast focusing is definitely a killer to record beautiful moments. The maximum aperture of the lens is 2.8, which provides a perfect blur for shooting portraits. The center image quality is clear and sharp, and the edge transition is as smooth as frost. The large aperture also increases the light input, and the ISO sensitivity of the camera can reach an astonishing 5 1200, which greatly improves the night shooting ability of the camera. Even if the shutter speed is fast, you can take a clear image in a dim environment. It is no longer necessary to take a heavy tripod with you when shooting night scenes. Holding night scenes is enough to achieve satisfactory results.

Nikon Z fc micro camera also keeps pace with the times, which is not only satisfied with photo shooting, but also optimized for video shooting. The camera supports shooting 4K/30p ultra-high definition video, and its eye detection autofocus function can also automatically follow the focus during video shooting, which is absolutely suitable for shooting simple life Vlog. The camera connected to the computer can even replace the webcam, providing clear picture quality for webcasting.

In response to this pain point, Sony, as the big brother in the field of micro-cameras, has launched an extremely powerful real-time tracking function based on artificial intelligence. This function can identify newly developed objects according to color, object distance, pattern, face and eye information for high-speed processing, and users only need to press half of the shutter to activate this function. Now this function has been successfully applied to Sony A7R4A, a new generation flagship camera in Quan Huafu. Let's see how this top flagship is suitable for eco-photography.

Sony's A7R series cameras have always been known for their strong image quality. Every time a new product is launched, it can be said that it is detonating the discussion upsurge of image quality in the whole camera market, and so is A7R4A. This time, Sony A7R4A adopts a brand-new Quan Huafu Exmor R CMOS back-illuminated image sensor with an effective pixel of about 665,438+0. Combined with Sony's excellent noise reduction technology, it can provide us with excellent image quality at high sensitivity. Although high pixel has always been the standard of A7R series, it is really shocking to reach 665,438+00000.

With the rapid development of digital cameras, more and more people use film cameras. The photos taken by film cameras can present retro colors and delicate picture quality, which are liked by more literary lovers. Fuji X 100V, a paraxial camera to be recommended today, simply brought me back to the film age, because both the appearance and the connotation exude a strong retro atmosphere, which makes people fondle it.

The ultra-high face value is the first eye-catching feature of Fuji X 100 V. Metal and leather are perfectly combined, and every detail is polished to the extreme. Retro paraxial design is my favorite, and every photo taken with it seems to have the taste of time. It adopts photoelectric combination, in which the electronic viewfinder adopts a brand-new organic light-emitting diode display screen, which has the advantages of high refresh rate and high color coverage, allowing photographers to see a more real world in the viewfinder.

Fuji X 100V is equipped with a 23mm F2.0 fixed-focus lens. This kind of lens is actually enough to position itself as a humanistic street camera. The 23mm wide-angle lens is enough to accommodate most scenes involved in daily street shooting, and the aperture of F2.0 is enough to realize the blurred effect of the legendary "opening like frost".
