What is DSLR? Digital single-lens reflex cameras (also called digital SLR or DSLR) are digital cameras combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to viewfinder.

History Who invented DSLR cameras? In 1969 Willard S. Boyle and George E. Smith invented the first successful imaging technology using a digital sensor, a CCD (Charge-Coupled Device). CCD would allow the rapid development of digital photography. Willard S. Boyle George E. Smith

For their contribution to digital photography Boyle and Smith were awarded the Nobel Prize for In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild 100×100 pixel CCD. CCD

What are the different lens sizes available for a DSLR camera?

Conclusion Photography nowadays is somewhat considered to be a kind of art. There is no art if there is no materials to use on. DSLR cameras are the materials used by artists of photography (also called photographers).
