What is the full picture?

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. For example, the CCD size of Canon EOS 350D is about 2/3 of the film size, and EOS 10D D is equipped with a lens of 100mm, which becomes a lens of 160mm after being converted into a magnification of 1.6.

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.

It is not the real size of CCD in the performance specification table of digital camera, but it can be obtained by a simple and practical method. The true focal length and equivalent focal length of the lens are generally listed in the digital camera or instruction manual. The ratio of the focal length of the 35mm camera to the true focal length is the ratio of the diagonal size of the frame of the 35mm camera to the actual diagonal length of the CCD, so that the real size of the CCD can be calculated conveniently.

For example, Panasonic LX2 (effective pixel120,000) portable digital camera adopts11.65 inch CCD, and the equivalent focal length of the lens is 28- 1 135mm, and the real focal length is 6.3-25.2mm, with the ratio of 4.44. 43.2/4.44=9.72mm, which is the effective diagonal length of11.65 inch CCD. Converted into 4/3 frame length-width ratio, the real size can be 7.38 x 5.54 mm, and the effective photosensitive imaging area of Panasonic LX2 camera CCD is only one twentieth of Quan Huafu size and one tenth of APS-C frame size.

There are four kinds of consumer digital cameras in the market: 2/3 inch,11.8 inch, 1/2.7 inch, 1/3.2 inch. The larger the CCD/CMOS size, the larger the photosensitive area and the better the imaging effect. 11.8-inch 3-megapixel camera is usually better than 1/2.7-inch 4-megapixel camera (the light-sensitive area of the latter is only 55% of the former). The increase of CCD/CMOS pixels with the same size is a good thing, but it will also lead to the decrease of the photosensitive area of a single pixel, which may lead to underexposure. However, in order to increase the number of CCD/CMOS pixels while maintaining the existing image quality, it is necessary to increase the total area of CCD/CMOS on the basis of at least maintaining the area of a single pixel.

At present, it is difficult to manufacture larger CCD/CMOS, and the cost is very high. Therefore, the larger the CCD/CMOS size, the more expensive the digital camera is. The size of the photosensitive device directly affects the volume and weight of the digital camera. The CCD/CMOS size of ultra-thin and ultra-light digital cameras is generally relatively small. The more professional digital cameras are, the larger the CCD/CMOS size is.

What do you mean by Quan Huafu and non-Quan Huafu 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.

What does Quan Huafu mean? What are the advantages?

The photosensitive chip area of the full-frame camera is relatively large, which is 24*36mm corresponding to the imaging format of the previous 135 camera. The advantage is that the imaging quality is good, but the manufacturing cost has also gone up and the price is higher.

What do you mean by SLR panorama?

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 conversion problems in lens use. For example, the CCD size of Canon EOS 350D is about 1/3 of the film size, and EOS 10D is equipped with a lens of 100mm, which becomes a lens of 160mm after being converted into a magnification of 1.6.

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. Converted into a digital camera, the closer the diagonal length is to 43.2mm, the larger the CCD/CMOS size is. In SLR digital cameras, the CCD/CMOS size of many cameras is close to 35mm film. For example, the CCD/CMOS dimension area of Nikon D 100 is 23.7 x 15.6, which is much larger than that of consumer digital cameras. However, the CMOS dimensions of Canon EOS 5D MARK II and Nikon D800 are both 36 x 24mm, reaching an area of 35mm, so the imaging is quite good. We call them Quan Huafu.

What's the difference between a full width and a 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.

What do you mean the camera is half full?

There is no concept of half a picture, only APS-C picture and Quan Huafu.

Quan Huafu is a photosensitive element with the same size as 135 film. The APS-C format is generally about 24× 16MM, and the specifications of APS format cameras from different manufacturers are slightly different.

The two full-width photosensitive elements are larger, and under the lens configuration with the same focal length, a larger visual range can be obtained, which is more convenient.

There is also a medium format, which is used in high-end cameras. Sensory elements are the same size as the film in medium format.

What does the whole road mean?

If the road is closed, it will be completely closed and half closed.

What does Canon Quan Huafu mean?

Quan Huafu refers to the size of traditional 135 film. In the past, the CCD size of most arc code 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 conversion problems in lens use. For example, the CCD size of Canon EOS 350D is about 1/3 of the film size, and EOS 10D is equipped with a lens of 100mm, which becomes a lens of 160mm after being converted into a magnification of 1.6. 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. Converted into a digital camera, the closer the diagonal length is to 43.2mm, the larger the CCD/CMOS size is. In SLR digital cameras, the CCD/CMOS size of many cameras is close to 35mm film.

What do Quan Huafu and Medium Format in SLR cameras mean? Thank you~

Refers to the size of the photosensitive element.

The full frame is the size of 135 film, 36 mm x 24 mm

Medium is the size of 120 film, that is, film with a width of 60 mm. Common sizes are 60mmx45mm (called 645), 60mmx80mm (called 680) and so on.

Digital SLR, digital photosensitive element CCD or CMOS scale is the above size, that is, Quan Huafu or medium digital SLR.

What does Sony Micro Single Quan Huafu mean?

That is to say, this camera is micro-single, and the size of the sensor is 36x24mm, which is equal to the negative size of the traditional 35mm film, which is called Quan Huafu.

Non-full-width microchip is 24x15.6mm sensor.
