Digital Camera: Optical Zoom Vs. Digital zoom | What is the difference between them ??
You must have digital zoom and optical zoom when you buy a digital camera or a camcorder; Hear these two terms. In addition to the number of megapixel sensors used in the camera, as well as any type of zoom used in the camera is also important. You must know the details of the zoom in these two types, because they are completely different from each other.
Optical zoom
Optical zoom is the actual focal length measurement of the camera lens. Focal length in photography is a very important term. Simply put, it's the viewpoint of the camera lens.
The simplest way to get the middle distance between the lens and the camera sensor. When the camera lens will be physically mounted in front, zoom will increase from the sensor, when the camera will reach the camera sensor smaller than the scene.
Digital zoom
Digital zoom is actually a type of technology that crashes a part of a digital photo, with magnifying effect that part is shown larger. Here no camera lens physically moves. Actually digital photos are made up of many small parts, called pixels. Simply put a digital zoom, using a technology, small pixels from any image are sorted and their size is enlarged, so that it can be expanded.
Fix lens camera
In particular, the digital SLR cameras have fixed lenses, which means that the lens can not be changed, so the company offers a digital zoom feature. The DSLR lenses can be changed, they are much more expensive than the fixed lens model. You can put the better or wide angle lens in just like the choice.
Most DSLR lenses do not have zoom ratings with "X" and numbers, but the focal length is measured. But with a simple figure you can easily zoom in. Use your camera's focal length, suppose it is 300 mm and the original focal length of your camera is 50 mm; This means that your lens has 6x zoom.
This is a very informative post.I was thinking about buying a camera but i had not much technical knowledge about lens,this will help me a lot.Thank's for sharing.
