Why is stabilization important?

What are the different types of stabilization technologies? Optical image stabilization, electronic image stabilization and CCD image stabilization.

If the shutter speed is fast enough, the natural shaking of the arm can be ignored, and above 1 125 can be left unused.

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.

The benefits of stabilization become apparent in poor lighting or when using a telephoto lens.

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.

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.
