DSLR Camera Full-form
To own a DSLR is quite common and predominantly trendy nowadays. The question is, do all the DSLR owners know what is the full form of DSLR? The full form of DSLR - Digital Single-Lens Reflex camera.
DSLR gives us high quality, good pictures, youth almost have an obsession to own a DSLR of their own, besides one must wonder from where this acronym comes from. Well, this is a digital SLR or the DSLR which combines the optics and the mechanism of a single-lens reflex camera coupled with a digital imaging sensor.
Next time, when you go on for an adventure or have set an event at home make sure your DSLR is ready to click the moments. Before that, let us know more about this fancy gadget.

DSLR full name is elaborated as a Digital single-lens reflex, it refers to a digitalized-based camera. This specially featured camera integrates the optics and the mechanism of the single-lens reflex camera with the help of a digital imaging sensor. To put it in simpler words, DSLR full meaning is a digital camera that uses the mirror to direct the light from the lens into the viewfinder. The viewfinder is actually a hole that lies on the back of the camera. This is used to preview the image before it gets captured. The DSLR camera also comes with interchangeable lenses. The interchangeable lenses enable the swapping of the lenses to get varied views of a scene.
The reflex design scheme is the basic difference between a DSLR and other digital cameras. In this reflex design, light travels via the lens and then towards the mirror, these alternates while sending the image to either a prism, that generally shows the image in the viewfinder, or this is the image when the shutter release button is then pressed. The viewfinder of a DSLR in reality presents an image that does not differ greatly from what is being captured by the camera’s sensor. The image presents as a direct optical view via the main camera lens. This is different from showing an image through a separate and secondary lens.
DSLR Camera Parts

Like the SLRs, DSLRs generally use interchangeable lenses coupled with a proprietary lens mount. This is a movable mechanical mirror system that gets switched down (exact at a 45-degree angle) to direct the light from the lens over a type of matte focusing screen via the condenser lens and by a pentaprism or pentamirror, this is an optical viewfinder eyepiece. This is mostly of the entry-level DSLRs that are used as a pentamirror instead of the traditional pentaprism.
Focusing can be done manually, by twisting the focus which is on the lens. This can also be done automatically by activating and by pressing halfway of the shutter release or a dedicated auto-focus (AF) button. In order to take an image, the mirror then swings upwards in the direction of the arrow, that is the focal-plane shutter that opens, and then the image is projected and is captured on the image sensor. After the actions, the shutter closes, and then the mirror returns to the 45-degree angle. This being the built-in drive mechanism that re-tensely processes the shutter for the next period of exposure.
This has been compared with the new concept as found of the mirrorless interchangeable-lens cameras. Here the mirror or the prism system has the characteristic which provides the different direct, accurate optical preview which separates the autofocus and the exposure metering sensors. These are the essential parts of all the digital cameras, which are the electronics like the amplifier, analogue-to-digital converter, image processor, and other microprocessors in order to process the digital image, also performing the data storage or driving an electrostatic display.
How does a DSLR work?
In this section, we will know about the workings of the DSLR. To proceed with:
The light enters the camera through the lens and then it strikes the reflex mirror.
The reflex mirror after which reflects the light vertically upward for focusing the screen.
Light passes through the focusing screen and then it enters the pentaprism which is a block of glass.
The pentaprism after which redirects the light through two separate mirrors then it gets diverted towards the viewfinder.
The viewfinder also gives you the live preview of the image that will be clicked.
Now when the button is clicked to take a photo the reflex mirror flips upward and thereby blocking the vertical path of light to keep it straight towards the image sensor.
Then, the shutter opens up and the light reaches the image sensor.

FAQs on DSLR Full Form
Q1. How Interchangeable Lenses Work in a DSLR?
Ans. There are actually these lens adapters that allow a lens for one lens which mounts to be used on the camera body with different other lens mounts but which is often reduced in terms of functionality. Many of these lenses are mountable, "diaphragm-and-meter-compatible". In modern DSLRs, and on the older film SLRs used the same lens mount.
Most of the SLR and the DSLR cameras provide an option to change the lens. While there are only a few exceptions from the MZ and ZX series of the Pentax film cameras which do not work with some of these older lenses. As is being implied by the above, the lenses are only directly interchangeable within the "mount system" on which they are being built.
Q2. What are Microprocessors?
Ans. A microprocessor can be defined as an electronic component that is generally used by a computer to perform its functions. This is a central processing unit on a single integrated circuit chip that contains millions of very small components which include transistors, diodes, and resistors that work altogether.
A Microprocessor is any type of miniature electronic device that does contain the arithmetic, logic, and even control circuitry that is necessary to perform the functions required to be functioned by a digital computer's central processing unit (CPU).
Q3. What is a Viewfinder?
Ans. A viewfinder is generally that part of a camera that displays the image to be taken and is only the part that is visible when the camera is held to the photographer's eye while taking the snap.
