The homely working of the Digital condenser and Film lens is one and the same. Both use the shutter, lens and aperture. The Lens captures the light and then it passes it into the aperture, which controls the light and the shutter opens and closes to control the duration of light, which enters.

The major difference is the technology of capturing the image. Digital lens does not use film to store the image. In digital achromatic lens an image sensor is used to score the image. It is a computer silicon chip. On the surface of this chip there are millions of pixels, which are photosensitive diodes.

The shutter chine of the digital hand lens activates a metering cell, which manages the shutter speed and passageway in tune to the expenditure of light apparition through the lens. When a person clicks on the glass shutter each and every pixel of the image sensor stores the intensity of the light, which falls on it by gathering an electrical charge. When strong light hits a pixel, it generates high weigh on and weak light generates low charge.

After the shutter closes maturity from every pixel is converted into digital numbers. This series of numbers creates an image on a computer screen.
