Is the stabilization function important for home cameras?

Sony's is good, I bought an 1850 model and forgot that it is better to have an anti-shake.

The stabilization function of most home cameras is achieved by simply increasing the sensitivity to speed up the shutter speed, and it is of no use value.

It doesn't matter if you don't have it.

Why is stabilization important?

Anti-shake technologies include optical image stabilization, electronic image stabilization, and CCD image stabilization.

If the shutter speed is fast enough, you can ignore the natural shaking of the arm, and above 1 125 you can do without using stabilization, which is useful for shooting with a slow speed, especially for beginners.

Most professional DSLR digital cameras do not have an anti-shake function, and there is no need to buy an expensive anti-shake lens, depending on the purpose of the camera and family situation.

The shaking of the arm is not only related to the shutter speed, but also to the focal length of the lens you are using, and the longer the focal length, the more noticeable it is (like holding a magnifying glass back and forth and not feeling anything, but the telescope hand can be noticeably felt with a slight shake).

If you're shooting handheld, you'll need to have a shutter speed that's at least a few seconds from the bottom of the focal length, but you'll often get a bad **, so you'll have to use a tripod, high sensitivity, or stabilization.

Canon's DSLR camera, of course, doesn't have image stabilization, thinking it's through "the lenses shake along".

The Olympus camera doesn't have an anti-shake lens because it's a "ccd that shakes along."

Fujifilm's I don't think it's called image stabilization, it's to shorten the shutter speed by increasing the sensitivity, I don't think it's kind, but it's funny, and I think it's good to use on a portable camera, but it's not cool to use on a DSLR.

The anti-shake function is only useful for scholars using long focal length and slow shutter, and advanced SLR mechanical cameras and digital cameras do not have anti-shake function, adding anti-shake affects the image quality, and due to the special structure of the anti-shake device, its anti-shock ability is very poor. Stabilization isn't a panacea, so you'll need a tripod to be stable. Stabilization is not a substitute for a tripod.

There are optical image stabilization and digital image stabilization, optical image stabilization probably has a built-in gyroscope, corrected according to the earth's gravity, digital image stabilization is corrected by software ** jitter.

The camera itself has a sensor that senses shake, and when it senses shake, it will send a command to drive a suspended lens in the lens to move in the opposite direction, which is optical image stabilization.

Electronic image stabilization is to improve the camera itself, the sensitivity, that is, the ISO value, and then let the camera shutter speed to implement image stabilization.

There are two types of camera stabilization, one is body stabilization and the other is electronic image stabilization. Electronic image stabilization is to increase the ISO value of the camera to increase the shutter speed, so as to achieve the effect of image stabilization, but a high ISO has an impact on the image and produces noise.

There are two types of body stabilization, one is lens stabilization such as Canon, and the other is CCD stabilization such as Sony.

Lens stabilization refers to the relative displacement of the lens to achieve the purpose of stabilization.

CCD debiting refers to the purpose of stabilization through the displacement of the CCD.

1. Correct posture

Most photographers hold their cameras in a similar position, but they tend to overlook the importance of body posture. Many people lean forward and use their arms to keep the camera steady. The correct posture is, like most heavy lifts, the best way to do it is to use your legs to carry the weight, so you need to adjust your foot posture to fit the following principles.

1.Hold the camera with both hands. The left hand holds the lens, while the right hand holds the body and controls the shutter.

2.Take a small half step forward and keep your knees slightly flexed. This distributes its weight evenly across both legs.

3.Raise your camera and pose for a general shot. For DSLRs, the viewfinder is held in front of the right eye, while for portable digital cameras, it is held about 15 cm in front of the face.

4.Clamp your arms at your sides. The left forearm should remain completely vertical and not extend forward beyond the toes. Be sure to avoid leaning forward, as this will cause camera shake.

2.On set, wrap one end of the rope around the camera lens so that the other end hangs down to the ground.

3.Step on the rope on the ground with one foot, then slowly raise the camera in front of you. Carefully straighten the rope, but be careful not to use too much force so as not to affect the body and lens mount.

4.When the rope is straightened, take a position as described in tip 1 and press the shutter gently.

II. II. II, grip method

1.The posture of the footsteps is the same as in the first technique, with the left foot in front and the right foot behind, shoulder-width apart.

2.Turn your upper body so that your left shoulder is facing the subject.

3.With your right hand, hold the camera in the recess where your left shoulder is attached to your body, under your collarbone.

4.The camera is held completely inward with the right hand facing inward. Keeping the weight of your body distributed over both feet, look at the viewfinder with your left eye. Take a deep breath and press the shutter.

Different manufacturers and models of cameras use different stabilization modes. Specifically, there are two types of in-body image stabilization and lens image stabilization.

Camera stabilization is a technology that reduces the low yield caused by shake when the user shoots with a handheld camera. The principle is that the anti-shake mechanism of the camera detects the shake generated when the user holds the camera, and then calculates the shake state and the amount of shake when the user holds the camera through the processor calculation, and then controls the anti-shake mechanism of the camera to produce the corresponding movement to offset the shake generated by the user's handheld camera, so that the camera can obtain the picture in a stable state when shooting, and improve the success rate of filming.

The principle is the same, but the way to implement stabilization is different......Specifically, there are two methods: body image stabilization and lens image stabilization. ......Body stabilization is the image sensor that controls the camera by the stabilization mechanism.

A state that produces motion to counteract jitter. Lens stabilization is a state in which the stabilization mechanism controls the motion of a certain group of lens groups in the lens to counteract the shake. Although the principles are different, the end result is the same ......

In general, SLR cameras.

Lens stabilization is used. Mirrorless camera.

The use of body stabilization. If you use your own DSLR lens to transfer to your own mirrorless body, it is said that body stabilization and lens stabilization can work together to bring a stronger stabilization effect.

However, stabilization isn't a ...... that works well at all timesIn the handheld state, stabilization is definitely useful and effective. However, if you shoot on a tripod, the stabilization function will be turned off......This is because the camera's stabilization settings are designed for low-frequency vibrations when shooting handheld. On the tripod, it is a state of high-frequency vibration, and the anti-shake mechanism is powerless, and even counterproductive......So, it's time to turn off the ...... stabilizationThe secondary lens must be turned off, and the original lens is best turned off ......

Current stabilization technologies are divided into optical image stabilization and CCD image stabilization, as well as a so-called natural image stabilization.

1.The representative manufacturers of optical image stabilization technology are Canon and Nikon. Let's take Canon as an example to talk about the principle of optical image stabilization.

Canon's optical image stabilization technology detects small movements by the gyroscope in the lens, and transmits the signal to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then compensates for the direction and displacement of the lens according to the direction of the lens shake by compensating the lens group, effectively overcoming the image blur caused by the camera's vibration. Canon's IS system takes only a very short time to move the IS lens group, so the results are still very good. In general, it is effective in preventing shutter times in the range of 1 60s.

The principle of anti-shake is to place the CCD on a bracket that can be moved up and down, left and right, and first detect whether there is jitter, because of the use of gyro sensors, the detection of jitter is basically the same as that of other companies. The sensor then detects the direction, velocity, amount of movement, ...... of the jitterThe detected signal is processed to calculate the amount of CCD movement that can be sufficient to counteract the jitter.

3.Natural image stabilization, Fujifilm has this technology in several machines, which is to increase the ISO to 1600 degrees, in order to increase the shutter speed to compensate for the shake, but this technology also greatly improves the ** noise, so it lacks practical significance in actual use.

From the above analysis, it can be said that the two machines you mentioned are the same, and in fact, neither has meaningful stabilization technology.

As for the role of image stabilization, it is mainly because there is less light entering the lens when using telephoto, so it can only be used for a long time, and at this time, the slight flutter of the hand will produce blur, and optical image stabilization is still useful in the absence of a tripod.
