If you are deciding to buy a new digital SLR camera, and would like to know about three new features recently available in the Digital SLR cameras, read on.
These three new features are:
- Dust Control
- Live View Mode
- Built in Image Stabilizer
Dust Control
In digital SLRs, or in fact in any SLR camera, the photographer has the ability to change the lenses in order to make the most out of type of photography involved. This feature means that when changing the lens, the interior of the camera, including the sensor is exposed to dust particles.
When dust enters the interior of a camera, it will land on the sensor and so blocks the light to reach the sensor in those dots.
The Anti Dust technology , or Integrated Cleaning System is a new technology that automatically shakes off the dust by using variety of techniques, such as shake, or static charges to repel the dust particles, or even software to identify the dots and remove them before processing.
Live View Mode
Until recently this feature which is widely used in compact digital cameras, was not available for digital SLRs. The reason is the difference between the build of a SLR and a compact camera and the way pictures are taken.
In order to be able to see a live view of a picture before the shoot, light has to be reflected to the sensor. As digital SLRs use a mirror to reflect the image from the viewfinder and meanwhile the mirror blocks the sensor, the live view is not possible, unless the camera is equipped with the new Live View LCD technology.
In Live View Mode technology a second sensor is build in the way of the light in order to transmit the light to the LCD.
Built in Image Stabilizer
This is not something new for a lens, but a new feature for the camera body. So why image stabilizer. This is equivalently called Anti Shake and is required if photographer requires to take pictures in low natural light, without using a flash particularly if they are moving objects, like children playing in living room.
Basically when the shutter speed is low in order to absorb more light, any slight movement will result in producing blurry pictures. High ISO setting will produce more noise or grain and if the lens is not equipped with a required wide aperture settings, then the only way to stop the blur is to have a camera with Anti Shake technology built in.
This technology is based on a simple concept of making sure that the camera sensor doesn't move and so cameras with this feature have sensors built in a certain way to stop them moving when handled by a shaky hand or when shutter speed is low.
