What is a DSLR
DSLRs have built-in mirrors (reflex) so the image you see
bounces up to the viewfinder. It passes through a focusing screen and a
condenser lens, and then reflects off of a prism’s walls to reach your eye.
This allows you to see exactly what the lens sees through the viewfinder. When
you hit the shutter release the mirror flips up to get out of the way. Once
this happens, the shutter opens and let the light pass through the lens to
imaging sensor, which is rated in megapixels (MP).
Simply put, a DSLR is just a camera that uses mirrors and
interchangeable lenses. One of the best features of a DSLR is the ability to
switch lenses. Each delivers a new and invigorating view. There are telephoto
lenses, wide-angles, fisheyes and many more. A telephoto lens lets you see
farther so you can zoom in on a far away subject, a wide-angle lens allows a
wider field of view which is great for landscapes and a fisheyes are extra
wide-angle lenses that distort images in unique ways (try to remember you’re
sober). A DSLR is one type of interchangeable lens camera. Hold up: A new
category of mirror less Compact System Cameras (CSC) also utilize
interchangeable lenses, but as the name suggests, these cameras do not use a
mirror and are not DSLRs, even though they are often mistaken as such. (Micro
Four Thirds is one type of mirror less camera.)
Advantages
Beyond the ability to swap lenses, the biggest advantages of
DSLRs vs. a point-and-shoots are photo quality and response. The majority of
compact digicams cannot match the quality of a DSLR since the imaging sensors
are much larger. The bigger the sensor, the better the photograph – it’s pretty
simple. And no compact can match the response or speed of a DSLR. This figure
is rated in frames per second (fps) and most DSLRs can capture at least 4 fps.
What this means is you’re more likely to capture your kid’s antics on the
soccer field or maybe get a good picture of a crime taking place – which is
what you bought a camera for in the first place.
Dealing with low-lighting can be challenging for any
photographer. As noted, point-and-shoots have smaller image sensors and lose
quality when you increase the ISO (sensitivity). With a DSLR you get a bigger
image sensor and the increase creates less noise in the photograph. Not only that,
but DSLRs allow much more versatility in how long you expose the sensor by
leaving the shutter open longer. In the settings of many point-and-shoots you
can adjust how long the camera exposes the image sensor to light but often only
up to a minute. DSLRs, on the other hand, literally let you expose the image
sensor for as long as you want in most cases. Some experienced photographers
will take landscape/cityscape photographs at night that can require exposures
of more than five minutes and DSLRs allow this, and they do it well.

Lastly, DSLRs let you modify your equipment beyond just the
lens. With a DSLR you can attach external flashes, fit filters onto the end of
the lens to affect colors and contrast, plus you can upgrade your battery with
an extended battery pack. The name of the game with DSLRs is versatility. If
you just want a camera for birthday parties and holidays, then you might be
fine with your smartphone. If you want a camera that has seemingly limitless
capabilities, great quality and speed, then you want a DSLR. Go crazy.
