The usage of an SLR camera it seems is much hassle free as when compared to that of a DSLR. All that a photographer needs to do is just press the shutter button usually situated on the camera head and a very simple mechanism starts acting where the camera mirror flips to release the sensor along with providing an adequate amount of exposure to the image to be captured.

DSLR And Its Functions:

A DSLR or a Digital Single Lens Reflex camera is much more advanced when compared to its counterpart, the SLR. The DSLR gives a much higher digitalized and good quality image as compared to SLR cameras.

The mechanism of a DSLR camera again is much more complex in nature and requires a lot of expertise in order to capture a good quality image with the various use and help of features available with the camera. Some of the very common and important features of a DSLR camera are as follows:

The Aperture

The aperture is a hole in the lens which allows for light to pass through the diaphragm. An aperture consists of various f-stops which would determine the exposure of the image and generally ranges from 1 to 16.

Image Sensor

An image sensor converts the image from digital signals to electronic signals to be sent to the memory card.


The body of a DSLR camera is much heavier as compared to the SLR which is lightweight and can easily be carried in a pocket.
