Tips On Buying A Digital SLR Camera
By
Russel Clark
Digital imaging
technology has improved dramatically over the past few years.
Previously, all serious photographers agreed that Digital
Single Lens Reflex (DSLRs) could not produce the same quality
and precision as conventional Single Lens Reflex (SLR) cameras
on a dollar-for-dollar basis. ie. a $1,000 SLR camera would be
far superior to a $1,000 DSLR camera.

Recently, the
technology has evolved to such an extent that Digital Single
Lens Reflex cameras are a great alternative for serious
amateurs or professionals. You actually now get more 'bang for
your buck' in that optically the lenses are equivalent and as
there are less moving parts in digital cameras, you are sure
to get fewer problems.
DSLR cameras
have a different imaging mechanism. Whilst the viewfinder is
similar to traditional cameras (optical viewfinder with
shuttered mirror), exposure is completely different. Standard
SLR cameras rely on mechanical or electric shutters which only
allow light in during the exposure cycle, DSLR cameras use a
light-sensitive sensor to capture the image. Light actually
comes in all the time, but the sensor only becomes 'active'
during the exposure cycle.
Most digital
cameras have a LCD on the back of the camera to activate of
change the camera's settings or features. You can now also use
the LCD to compose the shots. Non digital cameras don't have a
LCD and you will need to use the optical viewfinder to compose
the photograph.
In summary,
gives the best of both worlds. All the features of SLR
photography, which made it so popular such as precision
imaging and the ability to interchange lenses. Plus additional
benefits only available on digital cameras such as immediate
viewing of photographs and the ability to capture literally
thousands of photographs without 'changing spools'.
That said,
Digital Single Lens Reflex cameras may not be for you. These
are the key questions you should ask yourself before
purchasing a DSLR:
* How much can I
afford to spend? It's true that Digital cameras offer good
value, but as everyone is making the switch to digital, you
can usually find excellent traditional SLR cameras auctioned
off on ebay for a fraction of their true value.
* Do I really
need digital technology? The key benefit of digital technology
is the ability to immediately see your photo. This is
important if you're are a freelance news photographer, but not
that relevant if you specialize in still-life shots in a
studio setting
* Do I really
need interchangeable lenses. If not, consider a high quality
non-reflex digital camera. These cameras offer all the digital
advantages but come without the high price tag.
