The digital era has created a new, growing class of consumer-grade digital SLR (DSLR) cameras.
Single Lens Reflex (SLR) is a complicated term for a complicated machine. It refers to the prism and flip-up reflex mirror system that allows users to accurately focus and frame their shots directly through a cameras optics, rather than through a separate view finder. Until recently, most SLRs were the province of pros, requiring experience and training to master. But the digital era has created a new, growing class of consumer-grade digital SLR (DSLR) cameras that are easier to learn and use, yet still deliver pro-level photos. These days, the most complicated aspect of DSLR cameras is figuring out which one fits your needs.

Like most digital point-and-shoot cameras, digital SLRs have LCD displays the largest of which are about 7,5 cm, measured diagonally. Older model DSLRs didnt let you preview your shot using the LCD. Newer cameras with live view functionality leave the shutter open and allow light to bypass the reflex mirror. With most of these cameras, users have to choose between framing shots with the LCD or the viewfinder.
DSLRs have image sensors that are 10 to 20 times the size of sensors on point-andshoot cameras. This gives DSLRs far superior light sensitivity, which is arguably more important to overall image quality than megapixels. Most DSLR cameras can vibrate the sensor to remove dust particles that often enter the camera when changing lenses.
CompactFlash memory cards used to be the data storage capacity kings, but the far more popular Secure Digital High-Capacity (SDHC) format now has cards with up to 32 GB, and newer DSLRs are trending toward it.
