The CANON NB-6L Battery shutter release purposes is to prevent the moment the shutter caused camera shake, and in the use of B door exposure, don't have been the shutter, as long as the shutter button doesn't put online can, so also is one of the indispensable equipment in photography.
Most of the SLR cameras CANON NB-5L Battery all use electronic the shutter release, the advantage is directly connected with the fuselage, not connected in the shutter button, so that it can be based on the photographer choice of the way the shutter, use rise more convenient, and professional electronic the shutter release, also has the function of time, can set up the exposure time interval, photography, The Times of filming, can say all the can photograph are designed.
Mechanical the shutter release, mechanical shutter release from the traditional cameras continue, so there are a few of the SLR cameras use CANON NB-4L Battery, use method is to the shutter release XuanRu directly within the shutter button, so when shooting can only use the shutter release control and no other choice, it is not convenient, so now the SLR cameras don't use of mechanical design most shutter.
The remote control, general SLRS CANON NB-2L Battery mostly have connection the shutter release of the design, but some model adopted the design of the remote control. It USES the same with the shutter release, also can prevent press the shutter release cause camera shake, and control the time B door, the biggest difference is not directly connected with the camera, so the photographer can have a camera and the distance outside shooting, such as record himself.
The remote control in connection to prevent other photographers use remote control near the shooting and of generation influence each other, so in the back of the remote control design setting device, will own the remote control and camera connection device of adjusting button behind become unity format, will let their remote control can control his camera CANON NB-3L Battery. And reduce the remote control of the confusion with others mistakes.

When the use of FangDou lens photography skills
FangDou lens. Manufacturers in the Digital Camera Battery low speed in order to improve the shutter, handheld camera taking pictures of the success rate, so the design FangDou mechanism. Have this kind of mechanism, even if security shutter reduce 2 to 3 class can also clap a clear picture. For example: in the security shutter is 1/60 seconds, if lens is FangDou lens, so even if the shutter speed decreased to 1/15 SEC or 1/8 SEC also can shoot the clear pictures.
Generally speaking FangDou mechanism is composed of two groups of sensors, and correct image of the optical lenses. When sensors canon nb-2l battery induction to lens vibration, will judge is up and down around or shock, then drive corrective lenses correction of the same direction, can reduce the degree of fuzzy pictures.
Lens has no vibration, the light accurately focused on sensitive components. Camera shake down, the light cannot accurately focused on photosensitive Canon EOS 1100D Battery components, produced as poor, blurry images. The function of hand shake, corrective lenses and follow the lens vibration direction correction, the correction that like poor after become smaller, fuzzy reduced.
