Pao Q Pao A: how to choose between medium frame and full frame cameras?



 

There has been a lot of debate about the frame of digital camera. Some people think that the M4 / 3 or APS-C frame camera is enough, but others think that only the full frame or even the middle frame is the best. However, with more and more smart phones taking photos, camera products with larger size sensors can attract more consumers’ interest. Today, let’s talk about how to choose between medium frame and full frame cameras?

First of all, although there is a word “Zhong” in the Chinese painting, which literally feels smaller than the size of “Quan”, it is not. In the film age, frame often refers to the area of the camera’s imaging range on the film; in the digital age, it is not the film that is responsible for imaging, but the image sensor inside the camera. Therefore, we often refer to the area of the sensor. So what are the common picture specifications? According to the order from small to large, it can be divided into 1 / 3 inch, 1 / 2.3 inch, 1 inch, M4 / 3 frame, APS-C frame, full frame, medium frame, etc. the medium frame sensor itself also includes 44 × 33mm, 53.7 × 40.4mm and other different specifications. For example, the 44 × 33mm size sensor is used in the FUS gfx series which has been widely praised by consumers in recent years.

There is no doubt that this is the most remarkable feature of medium frame cameras. Larger frames bring more advantages in image quality. If a common sensor is magnified, it is actually composed of tiny pixels. This is what we often call “single pixel”. When the area of a single pixel is the same, the larger the size of the sensor, the more pixels it can hold, so it can bring more details. Compared with the common full frame, medium frame has the advantage of larger pixel particles, which means more light input. In this way, we can take photos with less noise and better picture quality in a more dark environment, and have better tolerance, and have more space for post production. In addition, the higher the pixel is, the larger the resolution size will be, and it will be more handy in the shooting and application of large-scale commercial advertisements. For example, the Fuji gfx 50s / gfx 50R has reached 50.6 million pixels, and the newly released gfx100s has more than 100 million pixels.

Fuji’s new China frame no anti gfx100s

Fuji’s new medium frame no reflection camera gfx100s is only 150 x 104.2 x 87.2mm in size, and weighs only 900g with battery and memory card. It is not only lighter than the previous gfx 50s, but also has advantages over many full frame cameras. In terms of specifications and parameters, Fuji gfx100s adopts 102 megapixel medium frame back illuminated CMOS sensor (43.8mm x 32.9mm), equipped with x-processor 4 image processor, and standard sensitivity range ISO 100-12800, which can be extended to ISO The gfx100s is equipped with a 5-axis anti shake system, which can achieve up to 6 levels of anti shake compensation effect. It also supports pixel displacement high-resolution mode, and can output up to 400 million pixels of still photos. In terms of focusing, the gfx100s is equipped with a hybrid auto focusing system of contrast detection and phase detection, with 425 (25 × 17) auto focusing areas.

Of course, if we put aside the quality only point, in fact, the full frame camera is more suitable for the mass consumers than the medium frame camera in all aspects. Although Fuji’s gfx series of medium frame cameras have brought the original medium frame cameras, which cost more than 100000 yuan, to a “low price” of 350000 yuan, for professional photographers or enthusiasts, it really saves a lot of money for themselves, and they can experience the previously inaccessible camera types with less money. However, for ordinary consumers, 100000 and 350000 do not seem to be much different. Therefore, it is undeniable that the emergence of Fuji gfx has made more and more people come into contact with medium frame cameras, but it is far from being as popular as full frame cameras. At the same time, due to the physical relationship between the sensor size and the lens flange distance and focal length, the medium frame lens is larger under the same equivalent focal length, and the overall mobility of the current full frame camera is better than that of the medium frame camera.

Full frame camera is more suitable for mass consumers

For photography, high-end equipment still has a large market and consumer groups, and this trend is more and more toward the development of professional products, among which everyone has more stringent requirements for camera image quality. Therefore, there is a saying in the market that “full frame is the barrier”. This is because many people think that full frame camera is a barrier that every user who really wants to play photography can not get around. Compared with other common small frame products, full frame camera can bring higher pixels, better noise control ability, and also has better performance in terms of body workmanship quality and focusing and capturing performance Performance. However, full frame is not the end point. For users who really need high image quality, a medium frame camera larger than full frame may be another goal.
