How to adjust the aperture of Sony camera
Where is the aperture adjustment?
1. If you want to adjust the aperture of a SLR camera, first adjust the shooting file of the camera to A file, and then find the shoulder screen of the adjusted camera, and then the user can adjust the aperture by simply dialing the shoulder screen. This still needs to be understood.
2. What needs to be understood about the camera aperture is that the aperture size is related to the amount of light entering. The larger the aperture, the greater the light input, while the smaller the value behind the aperture f, the brighter the picture, the narrower the focal plane and the more blurred the background of the subject.
3. On the contrary, the smaller the aperture, the smaller the amount of light entering and the larger the value after F ..
4. Data expansion: The aperture is a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens, usually in the lens. We use F/ value to represent the size of the aperture, and the function of the aperture is to determine the amount of light entering the lens.
5. For the manufactured lens, we can't change the diameter of the lens at will, but we can control the luminous flux of the lens by adding a polygon or circular aperture grating with variable area inside the lens. This device is called an aperture.
In the automatic mode of Sony a7 aperture, the brightness cannot be adjusted manually. If the light is not enough, the machine will automatically adjust to the maximum aperture. Aperture is a numerical value of SLR camera. Like shutter and ISO, different apertures can make photos have completely different effects. If you take a picture with a large aperture, you will get a very blurred picture, which looks very artistic. Aperture adjustment: After focusing is completed, we will adjust the aperture of Sony HD camera appropriately, in order to make the image clearer. We need to find the aperture adjustment screw of Sony HD camera and turn the screw button gently.
How to adjust the aperture of Sony 1650?
Manual aperture adjustment method of Sony 1650
1. First, we adjust the shooting file of the camera to one file.
2. Then see if your camera has a shoulder screen, and then dial the front and rear wheels (control dial) to try.
3. If the data of FXX has changed, then the aperture has been adjusted.
4. If the SLR camera has a shoulder screen, turn the dial wheel to adjust the aperture value and display it directly on the shoulder screen.
How to adjust the aperture value of Sony micro-single
The aperture adjustment of Sony micro-single is not on the aperture, but on the fuselage.
The specific position is on the upper panel of the fuselage, and there is a control wheel, which can adjust the aperture by turning.
"Micro-single" camera is a cross-border product located between digital SLR camera and card machine. Its main structural feature is that it has no reflector and prism. "Micro-single" is a trademark of Sony.
The history of human development proves that no technology can be brilliant forever. In the film age, film, the medium for storing images, must be strictly protected from light leakage when taking pictures. However, in the digital age, the situation has changed fundamentally-CCD is not afraid of light leakage. It can be used not only for framing, but also for imaging after clearing. Therefore, the necessity of reflector is greatly reduced. Its working principle determines that reflector framing is not suitable for digital photography. There is no need to keep the mechanical part-reflector on the digital camera that can be completely electronic.
Although people can tolerate the bulky and complicated structure of the reflector, because they can both watch through the lens and protect the film from light leakage, in today's digital age, because the image sensor is not afraid of light leakage, the existence of the reflector is no longer necessary. With the improvement of electronic viewing technology, the clarity and brightness of electronic viewing will be good enough to replace the reflector sooner or later. Therefore, in theory, a single electric camera can have almost all the advantages of SLR cameras-better image quality, greater depth of field and replaceable lenses. Once waiting for the demand to break out, such a problem will definitely be solved, and the size of a single electric camera is an advantage that SLR can never catch up with.
Before Sony introduced the "micro-camera", consumer electronics giants such as Olympus, Panasonic and Samsung had introduced products without mirrors and using electronic viewfinder, which could change the lens like a SLR and called it a "single-camera". Hidehiko Handai, head of Sony's personal audio-visual department, said that "Micro-single" is a trademark specially used in the China market, and its products have been given two meanings: micro-camera, compact and portable, which can change lenses like SLR cameras and have the same image quality as SLR cameras.
Where is the aperture adjustment of Sony a73?
Sony a73 aperture is adjusted on the dial as follows:
1. Turn the dial to position A, which is the aperture priority mode.
2. Turn the wheel on the camera shoulder screen. If the number after f on the screen changes, the aperture is also changing. The larger the value, the smaller the aperture, and the smaller the value, the larger the aperture.
3. If the depth of field is small, increase the aperture, so that the camera shutter speed is also fast.
4. If you need a large depth of field, lower the aperture. The shutter speed is slow, but there is more light.
Sony a73 is a Sony camera. Sony is a multinational company, whose business involves electronics, entertainment, finance and other industries. It was founded by Ibuka and Akio Morita in May 1946, and its headquarters is in Tokyo. Sony's business scope includes smart home, video games, communication products and information technology.
