Review: Panasonic SDR-SW20 SDHC Camcorder
For years we've been telling people to keep their
camcorders away from sand and water - only to find that
Panasonic's SDR-SW20 is happy lying on a windy beach or
swimming with the fish. Has the world gone mad?
Since the dawn of civilisation we've been warning
camcorder users of the risks involved in taking a camcorder
onto a beach or letting it get anywhere near water. It's one
of the things no self-respecting camcorder owner would ever
do. Until now, that is.
Such advice still holds true for pretty much all camcorders
past and present, but Panasonic has now gone and thrown a
spanner in the proverbial works by bringing us a camcorder
that you can not only cover in sand but which can actually
withstand a dunking in the rolling surf or swimming pool. At
the outset, this seems completely barmy - but no. Panasonic's
"tough, active" solid-state SD video camera really is
shockproof, waterproof and dustproof. All within reason, of
course.
First impressions
Let me say right up front that I really like the form factor.
It's a neat, compact yet ruggedly-built device that feels
pretty much like a reasonably large (OK - very large) mobile
phone when closed up and carried in the hand. Shove it into a
pocket or bag when not in use and you hardly know it's there.
Furthermore, if you see something you want to grab on video
right away then all you have to do is open the LCD screen,
switch it on, and you're ready to roll in less than a second.
0.6 seconds, to be precise. Why? Because the whole thing
relies on solid-state recording technology based around
high-capacity SD cards (SDHC) and has no moving parts
whatever. It comes in two colour-ways - an eye-catching red
and also silver.
Perhaps the best thing about it, apart from its rugged good
looks, is the lack of controls around its slinky body; open
the LCD screen and you have a main power dial, a large
circular function dial with buttons placed around and within
it and - most importantly - a "Trash" button with which to
delete the stuff you really don't want your parents to see
when you get back home.
Features
What I particularly like about the SW20 is its lack of
physical features. However, before I get accused of having
sold out completely and am now giving in to the pressures of
rampant consumerism where I would once have been critical of
such things, let me explain that I'm looking at this from the
viewpoint of the all-important target user, as always. So, as
a reminder, this camera is not aimed at serious video-makers,
it's aimed at those people who would otherwise use their
camera phones to grab quick, snappy and fun clips whilst out
on the town or taking a holiday. Moreover, those same users
are more likely to squirt clips up to YouTube and MySpace
rather than spend hours carefully honing their project into a
60-minute holiday DVD complete with titles, mood music and
commentary. In that context, the SW20 strikes me as being
ideal for its market.
It shoots onto SDHC (high capacity) cards - of which
Panasonic and others are now offering capacities of 32GB -
and these slot into the underside of the camcorder where the
super-slim battery also lives. The only connectivity with the
outside world comes in the form of a USB 2.0 mini-B socket
and AV-output socket (cables for both included) which are
found sharing a compartment with the DC input socket behind a
plastic door on the outer rear of the cam. And that's about
it.
I've mentioned already that the SW20 is waterproof and even
shockproof, so let's examine this a bit more closely. You can
take it into water - fresh water and even sea-water - but to
a depth of 1.5 metres only, so if you're a scuba diver or
deep-sea diver you'll still need to make other arrangements.
Furthermore, its shock-proof capabilities are limited to its
being dropped from a height of no more than 1.2 metres,
although even that is pretty good in that it can slip off a
table or out of your pocket without your having to confess
the fact to its rightful owner. Such resistance to shocks is
partly due to the fact that there are no moving parts
whatever outside or in - another plus for cameras that use
flash memory cards. Being dustproof, you can actually record
in places where other camcorders dare not venture - onto
windy beaches or arid deserts being just two. I can't think
of any more but I'm sure you get my drift.
Image Sensor, Lens and Other Stuff
The SW20 uses a single 1/6", 800,000 pixels, CCD image
sensor to generate pictures with an effective resolution of
400,000 pixels in the tradition 4:3 aspect ratio and 350,000
pixels in 16:9 widescreen. You can choose which mode you want
in its very well-designed and easy-to-navigate graphical menu
system. The zoom lens offers an optical zoom ratio of 10x
(2.3mm to 23mm) using a F1.8 to F2.4 Panasonic video lens.
Digital zoom (in which electronics are used to magnify the
image) options are 25x and 700x. The camera can be used to
shoot movies and digital stills to an SD or SDHC card in
light as low as 12 lux, although the "Colour Night View"
function will enable you to get low-resolution pictures in
light as low as 2 lux.
Performance
Well, it's not high definition, but we're not asking it to
be. Its single CCD doesn't even record what we might refer to
as "proper" widescreen either; the CCD generates an image
measuring 704x576 in PAL (UK, Europe, Australasia, etc) and
704x480 in NTSC (North America, Japan, etc). It produces
widescreen by squeezing the image into the 4:3 image space
and then un-squeezing it on playback (this is quite normal
for non high-definition spec consumer camcorders). In optimum
lighting conditions, the SW20 produces remarkably good
pictures, although it's fair to say that shooting in low
light (indoors, at night, with normal domestic lighting)
produces pictures that lack colour definition and are
somewhat grainy. However, we should again consider the
product with its target market in mind - and in that respect
it's very good indeed.
Connectivity and Sharing - YouTube too!
Movie clips and digital stills pictures can be exported to
either a Windows/Vista PC or Apple Mac using the supplied USB
cable for a direct connection, or the SD/SDHC card can be
removed and placed into a separate card reader for onward
importation. Panasonic has bundled MotionSD Studio 1.3E
software to enable movies to be imported and very simply
edited in PCs, but for Mac users it's easier because it
should simply be a case of importing direct into iMovie,
providing that the Mac is running on MacOSX (10.4 Tiger) or
upwards. We tested the output of the SW20 by importing
directly into iMovie '08 running on Mac OSX 10.5 (Leopard)
without any problems, and with very acceptable results.
Users can also burn DVDs without using a computer by
acquiring the optional Panasonic VW-BN1 DVD Burner. This
connects direct to the SW20 using its own USB cable and
allows DVDs to be made thanks to the camcorder's built-in USB
Host software. With it, you can make copy of all of your
clips (depending on the capacity of the memory card, of
course) or selected clips assembled into a playlist. This is
useful for making backups of card contents whilst away from
home, for instance (although the VW-BN1 does require AC mains
connection to operate).
We've established already that the target market is likely to
want to share, quickly and effortlessly, their movie clips
online using YouTube and the like, so I'm impressed to see
Panasonic working with both Pinnacle and YouTube in making it
easy for users to shoot clips with their SW20, perform simple
editing using the optional (and free to download)
Pinnacle
VideoSpin software and then upload the results to
YouTube in a single workflow.
VideoSpin is an interesting new venture by Pinnacle in
that they're offering beginners' video editing and online
sharing software completely free for the basic operations.
What costs money is the upgrade to wider functionality - such
as the ability to upload, in a single click, clips to YouTube
and the like. Purchasers of the SW20 can take advantage of a
special deal that enables them to access wider functionality
- such as the ability to upload their finished project to
their YouTube account - without having to pay the usual
$15.00 upgrade. This is a good example of "joined-up
thinking" on the part of camcorder and software companies -
it's what people want to do, so why not?
The analogue AV playback option produces impressive results
when showing on a 28" non-HD TV screen, and even the sound is
good. Like many comparable consumer cams, the built-in
electret microphone does tend to react to wind noise, but for
the large part it does a good job and stereo definition and
separation are pretty reasonable.
Conclusion
The SDR-SW20 isn't what we might call a "serious videomaker's
camcorder" but then again it isn't intended to be by any
stretch of the imagination. What it is, though, is a
lightweight, no-nonsense, video camera that you can take
anywhere and shoot fun clips quickly and easily without all
the hassle involved in using what might be termed
conventional digital video camcorders.
Not only might some people find it immensely useful to be
able to take a camcorder onto the beach without having to
worry about grains of sand rendering it useless, but the fact
that it can shoot under water to a reasonable depth will make
this very attractive to many people. The fact that there are
no moving parts and that it records movies and pictures to SD
memory cards is a major plus point, of course.
Pictures and sound are very good in optimum conditions - just
don't expect brilliant images in dark corners. However, given
the fact that Panasonic is looking seriously at how users
might gain access to fuss-free methods of importing, editing
and uploading their favourite clips to the web with the
minimum of hassle, I have to say that the SW20 looks like
being a winner. And going by the reaction to the red model by
members of my household, I have to say that it has a fair
chance of being considered "cool" by members of its target
market. Who am I to argue? Good stuff, Panasonic.
