Most users prefer to choose a smaller and slick camcorder. Smaller camcorders
tend to have smaller lenses and imaging pick-up device, the CCD
(Charge-Coupled-Device). The recent advancement in electronics and optical
technology allows manufacturer to provide really small and light but capable
camcorders.
Take for instance, the Panasonic GS-200K and
Sony DCR-PC330 are both slim and feature-rich camcorders. They are small and
light enough for extended traveling and the quality is quite good, claimed to
match broadcast quality.
However, there are a few factors to consider
that could affect the overall image quality.
|
The Lens
Basically, choose a camcorder with a 'branded' lens. Not
necessarily very good, but better than ordinary ones.
Most manufacturers now engage famous lens makers for
their camcorders' optics. Sony uses Carl-Zeiss lens
whereas Panasonic leverage on Leica lens. Canon on the
other hand, uses their own lens since they are well
known for producing good lenses themselves.
A bigger lens diameter
permits more lights entry, thus producing better and
brighter pictures. 30-42mm in diameter lenses are quite
common among consumer camcorders today. Besides that,
also look out for the max aperture size, the "F-stop"
value. Most camcorders' apertures open-up max at F1.8,
and better if it goes smaller. The best seen so far for
lower end models is F1.6. Expect the latter to provide
brighter images.
Focus length or zoom is one
of the hottest feature most buyers demand. The more
times the zoom the better. 10X to 16X is quite common
and it's usually enough because zooming into the max end
risks instable/shaky pictures. |

The CCD (or imaging
device)
At the heart of the camcorder, is the imaging device,
the CCD. This device captures the images from the lens
and converts them to electrical signals to be further
processed and saved onto the tape or media.
Most consumer camcorders use one CCD with a color filter
to approximate colors, but the recent advancement in
technology and maturity in imaging sciences have allowed
some manufacturers like Panasonic and Sony to bring
3CCDs camcorders to home users.
Broadcast level camcorder
uses 3CCDs to capture true to life colors (to know more
about this technology

fidelity - rich and vibrant colors.
Another factor that dictate
the quality would be the size of CCD. Smaller CCD is
poorer in capturing light, which makes shooting in dim
or indoor events difficult. Often, such videos turn out
to be too dark and grainy, resulting in wash-out colors.
Choose a camcorder with bigger CCD if you shooting
indoor is your priority. For now, most manufacturers
tend to lean forward to smaller CCDs to create really
small camcorder.
Common CCD sizes:
-
1/3"
(bigger)
-
1/4"
-
1/4.7"
-
1/5"
-
1/6"
(smaller)
The
bigger the CCD, the more expensive the camcorder. For
superior low-light shooting, choose a model with a
bigger CCD.
The commonest size in the market now would be the
smallest : 1/6" which allows smaller camcorder to
be built and also lower in cost. |

Other features
Still (photo) capture
You might be amazed but confused about the product positioning
today. Are they selling a video or a still camera? Most digital
cameras now can take moving images and videos and of course, the
other way round, video cameras or camcorders now can snap pictures!
Please bear in mind that even the most
expensive camcorder now does not take still picture as good. Don't
be overly amazed and believe that a digital camera's video is good
enough, and it never was and it won't be, at least for the few years
to come. If you have limited budget, and you are only interested in
movie making, spend wisely. Look out for features that are important
to video making such as video quality, stabilizer, but not built-in
flash, still capture resolution, memory card types etc.
Stabilizer
Almost all camcorders now feature at least some form of
stabilizing mechanisms, but basically there are two major type :
1. Optical and
2. Electronics
Optical stabilizer is better but only
available in more expansive models. They are usually present in
prosumer range, that costs more that US$1,200 (RM 4000). The 2
cheapest models with optical stabilizer now are :
1. Panasonic PV-GS400 and
2. Sony DCR-HC1000
both being 3CCDs models. Optical stabilizer does not impair image
quality as the stabilizing mechanism works on the optical level,
adjusting the lenses on the fly to correct shakes.
Electronic Stabilizer are present in
most camcorders. It is effective but some models exhibit lower
quality images when it's switched on. The stabilizing feature is
done on captured video images through high-speed processing
circuitry. Since this applies another level of processing, the final
output might be of lower quality than without. However, the recent
advancement in digital signal processing technology has made
electronic and optical stabilizing comes very close in terms of
quality. Without thorough examination, it's hard to differentiate
the minor quality improvements the optical version offers. |
