What is a full-frame camera?

Question 1: What are the advantages of a full-frame camera? What is a full-frame camera? Full-frame camera refers to a digital camera with the same sensor size as 135 film, which is 36×24(mm). The advantage of full-frame camera-the larger the sensor size, the higher the imaging quality under the same pixel. Quan Huafu's SLR imaging quality is higher than other SLR digital cameras. There are no restrictions on the use of lenses. The modern mainstream SLR is dominated by APS-C frame (about 24.9× 16.6mm), which is about 2/3 of the film size of 135, and its lens conversion ratio is about 1.5~ 1.6. For example, Canon EOS600D is equipped with a lens of 100mm, which becomes a lens of 160mm after being converted into magnification of 1.6.

Question 2: What is the whole picture? Lens or camera? Full width means that the photosensitive element of the camera is the same size as the film of 135 camera, that is, the diagonal is 36 mm x 24 mm

This excellent gallbladder can develop a relatively large-format photo without being affected by clarity.

Question 3: What is a full-frame camera? Quan Huafu refers to the size of traditional 135 film. In the past, the CCD size of most digital SLR was smaller than that of 135 film, while the CCD size of Quan Huafu digital SLR (or CMOS photosensitive imaging element) was the same as that of 135 film. The larger the CCD size, the higher the imaging quality.

The size of the traditional camera film is 35mm, that is, the width of the film (including the punched part), and the photosensitive area of the 35mm film is 36 x 24mm. When converted into a digital camera, the diagonal length is about 35mm, and the larger the CCD/CMOS size is. In SLR digital cameras, many have CCD/CMOS dimensions close to 35mm. For example, the dimensions of Nikon D 100 and CCD/CMOS reach 23.7 x 15.6, which are much larger than consumer digital cameras, while the CMOS dimensions of Canon EOS- 1Ds are 36 x 24mm, reaching an area of 35mm, so the imaging is relatively good. We call them Quan Huafu.

Question 4: What's the difference between a SLR Quan Huafu and a non-full-frame camera? Quan Huafu refers to the size of traditional 135 film. In the past, the CCD size of most digital SLR was smaller than that of 135 film, while the CCD size of Quan Huafu digital SLR (or CMOS photosensitive imaging element) was the same as that of 135 film. The larger the CCD size, the higher the imaging quality. Moreover, for users who already have traditional SLR, there will be no conversion problem in lens use. Non-full-frame cameras, such as Canon EOS 400D and 50D, have a CCD size equal to about 2/3 of the film size, and a lens with 100mm becomes a lens with 160mm after being converted into a magnification of 1.6 times. At the wide-angle end of 24mm, Quan Huafu has an advantage and a very broad vision. However, it is awkward to use in Quan Huafu, where X 1.6 is equivalent to 38mm. 。

The size of the traditional camera film is 35mm, that is, the width of the film (including the punched part), and the photosensitive area of the 35mm film is 36 x 24mm. When converted into a digital camera, the diagonal length is about 35mm, and the larger the CCD/CMOS size is. In SLR digital cameras, many have CCD/CMOS dimensions close to 35mm. For example, the dimensions of Nikon D 100 and CCD/CMOS reach 23.7 x 15.6, which are much larger than consumer digital cameras, while the CMOS dimensions of Canon EOS- 1Ds are 36 x 24mm, reaching an area of 35mm, so the imaging is relatively good. We call them Quan Huafu.

Question 5: What does a full-frame camera mean? The camera with the same size as the 135 film (36mm*24mm) commonly used in the previous film era is a full-frame camera with APS-C camera. The size of the sensor is smaller than that of Quan Huafu, so it is commonly used, and the image quality is slightly weak. Therefore, Quan Huafu is a commercial concept in the digital age, which is technically called 135 frame.

Question 6: What do you mean by Quan Huafu people and non-Quan Huafu people in the camera? What is the difference? This refers to the size of the sensor. The larger the sensor size, the better the image quality of the camera and the higher the price of the camera.

The length and width of Quan Huafu sensor is about 36x24mm, which is as big as the negative of traditional 135 film. It is an advanced sensor at present, mainly used for high-end SLR.

As long as the size of the sensor is smaller than that of Quan Huafu, it can be called a non-Quan Huafu sensor, which mainly refers to the APS-C format sensor with entry-level and mid-range SLR, and its length and width are about 24x 16mm (the sensor sizes of different manufacturers are slightly different).

There are smaller sensors, such as M4/3 sensor, 1.5 inch sensor, 1 inch sensor,1/0/.7 inch sensor, 1/2.3 inch sensor and so on, which can also be collectively referred to as non-Quan Huafu sensors.

Question 7: What's the difference between full width and half width? The difference between a full-frame camera and an incomplete camera lies in the size of the photosensitive element of the camera itself. Therefore, a lens with the same focal length can shoot different ranges on cameras with different frames.

If you want to take exaggerated photos with a wide-angle lens, use a full-frame camera, and the focal length of the lens will be truly reflected in the photos.

Instead, you need to multiply the focal length conversion factor by a camera that is not fully colored. The focal length conversion coefficient of each camera is different. For example, when shooting on EOS 50D, the focal length is 18mm. The actual focal length should be multiplied by the focal length conversion factor 1.6,18mm×1.6 = 28.8mm. ..

Answer supplement:

The complete series of aperture values are as follows: f 1.0, f 1.4, f2.0, f2.8, f4.0, f5.6, f8.0, F1,f 16, F2. And the amount of light entering the upper layer is just twice that of the lower layer. For example, if the aperture is adjusted from F8 to 5.6, the amount of light entering will be doubled. We also say that the aperture is enlarged by one level. The luminous flux of F5.6 is twice that of F8. Similarly, F2 is 16 times the luminous flux of F8. When F8 is adjusted to F2, the aperture is enlarged by four levels. For consumer digital cameras, the aperture f value is often between f2.8-f 1 1. In addition, many cropping cameras can adjust the aperture of 1/3 when adjusting the aperture.

I suggest you study photography systematically. These are the basic concepts of photography.

Question 8: What is a Quan Huafu SLR? What are the advantages of full-width SLR? Quan Huafu means that the CCD/CMOS area of the photosensitive element of a digital camera is as large as the film of the same specification (i.e. 36×24mm). However, due to the difficulty and high price of CCD/CMOS, most digital cameras are not made in Quan Huafu at present. CCD/CMOS is smaller than a 135 film, and its imaging area is also smaller. Generally speaking, DSLR is larger than small DC. The most common frame between them is APS-C frame.

APS is called advanced photo system and has been eliminated. There are three sizes of APS film: C, H and P. The H type is Quan Huafu (30.3× 16.6mm), and the C type (24.9× 16.6mm) is one end of the left and right ends of Quan Huafu, with an aspect ratio of 3∶2, and the P type (30.3×10. Digital SLR borrows this standard, and 22.5× 15.0 mm and 23.6× 15.8 mm which are close to the size of C are called APS-C frames. The 28.7×1mm of EOS- 1D and 1DMkII are called APS-H frames.

There is usually another representation, that is, 1.3 times/1.5 times 1.6 times, which means that the diagonal size of Quan Huafu is multiple of the diagonal size of the camera imaging element, the conversion ratio of Canon is1.6 times, and that of Nikon is 1.5 times. Taking Canon EOS 400D(APS-C format) and a 18-55mm lens as examples, the equivalent focal length of a digital camera multiplied by 1.6 lens will become 28.8-88mm, but if Quan Huafu SLR is matched with 18-55mm lens, the focal length will remain unchanged.

Therefore, Quan Huafu has obvious advantages, not only can make full use of the old lens, but also because the CCD/CMOS area of the photosensitive element is large, so the more photons captured, the better the photosensitive performance and the lower the signal-to-noise ratio. This is why Quan Huafu SLR is a major trend of digital SLR development in the future.

Question 9: What does the SLR camera Quan Huafu mean? Simply put,

If it is not a full-frame camera, the photos you actually take will be smaller than the images you see in the viewfinder!

With a full-frame camera, the photos you take are the same size as what you see in the viewfinder. .

You can find a non-full-frame camera to compare. .

Question 10: What is a full-frame camera? The 50-point full-frame camera refers to a digital camera with the same sensor size as the film size 135, which is 36×24(mm). The advantage of full-frame camera-the larger the sensor size, the higher the imaging quality under the same pixel. Quan Huafu's SLR imaging quality is higher than other SLR digital cameras. There are no restrictions on the use of lenses. The modern mainstream SLR is dominated by APS-C frame (about 24.9× 16.6mm), which is about 2/3 of the film size of 135, and its lens conversion ratio is about 1.5~ 1.6. For example, Canon EOS600D is equipped with a lens of 100mm, which becomes a lens of 160mm after being converted into magnification of 1.6.
