Video Camera Review of the Panasonic NVGS280 Digital Camcorder
This review assumes a basic understanding of the
appropriate technology. Reviewed October 2006.
Background to our purchase
Just the day before our 2005 Dorset holiday
we discovered that our trusty JVC DV1 digital camcorder recorded no sound,
forcing us to drag out of mothballs our aged 12 year old Sony analogue Hi8
model. So a few weeks prior to our 2006 Somerset
holiday we researched a suitable replacement on the Internet and in the
consumer press. We wanted to stick with the Mini DV tape format -
footage is easier to transfer and edit on the computer and we need to play
our existing tape collection - plus we required something lightweight.
The Panasonic NVGS280 digital video camera seemed to fit the bill, we
particularly liked the high quality credentials and hybrid built-in digital
stills camera which we hoped would save us from carrying and operating two
cameras - video and still - on our travels...

better performance can be achieved by removing the lens cap!
Internet order
Searching the Internet turned up a number of suppliers, unfortunately
with the model out of stock at many. We then discovered it in stock at
a retailer we've used in the past - PRC
Direct, and at a good price too, so we ordered. While waiting the
few days for delivery we downloaded the instruction manual from the Panasonic
website to familiarise ourselves with it. We thought it prudent to
have a second rechargeable battery, so another online search for a supplier
and we ordered from Battery
Force (and at one-third the Panasonic price!) - it arrived next
day. We did the same for some DV tapes, found Postfree.biz
and got branded Panasonic tapes at half High Street prices. Finally we
ordered some SD memory cards, a UV filter and lens cap from 7
Day Shop.com, a dealer we use regularly.
Panasonic NVGS280 hybrid digital camcorder features
Panasonic makes much of the camera's high quality credentials - 3CCD's,
Leica Dicomar lens and Crystal Engine. Other major features include an
Optical Image Stabiliser (OIS), Anti-Ground Shooting (AGS), 10x optical zoom,
manual overrides, colour night view, and a 3.1 megapixal (mpx) digital stills
mode using SD card media. It has a foldout 2.7 inch dynamic LCD screen
and viewfinder (both colour), zoomable mic with wind cut filter, widescreen
recording and two tape speeds. Connections are provided for USB and DV
(FireWire), S-Video and stereo sound out and external mic in.
Setting up decisions
We like to get the best out of our kit, so we spent some time
experimenting with the various video, sound and stills settings on our new
camcorder:
SP/LP - The LP speed allows a 60 min Mini DV tape
to run for 90 mins. The user guide indicates there's no quality drop at
the lower speed, but warns of possible pixel blocking, particularly with non
Panasonic tape and of poor slow motion playback. We tried it on LP with
another DV tape brand (ooh er!) and even during rapid pans and zooms of
buildings (a good stress test of digital video encoding), there were no
picture or playback problems. However, we noticed the sound (16 bit)
seemed a bit more woolly and there were sound glitches at some stop/start
points. We set the speed to SP as the Mini DV tapes are
inexpensive. These days data storage is plentiful and cheap, we have
tons of hard disk capacity and save edited video to DVD anyway.
PCM 16 bit/12 bit sound - The lower 12 bit sound
quality allows a second stereo track to be dubbed to tape after filming, eg
to add a commentary. As we can edit footage during post production on
the computer, we had no need for this feature so set this to 16 bit.
Wide/4:3 - The camcorder can record both video and
stills with a 16:9 widescreen aspect ratio. We found the image actually
wasn't any wider, just shorter. Although it looked good, in fact it
records less data to tape or SD card. With 16:9 the digital stills
pixels reduce from 3.1 to 2.4 megapixels, a serious reduction here.
Again, we can easily crop video or stills during post production if
necessary, so we set this to 4:3.
Mic settings - The on-board microphone has a wind
noise reduction and zoom function. We found the wind cut only
marginally effective (see later) and the zoom mic - it supposedly zooms in
the sound to the subject with the picture - rather useless as it had an
adverse effect on sound quality. We decided to only use these when
necessary and investigate using a stick-on wind jammer or an external mic -
with fluffy wind gag - clipped onto the accessory shoe.
OIS -The camera has an Optical Image Stabiliser
which works well at reducing camera shake so we set this on.
Zoom ratio - The optical zoom runs up to 10x, the
digital zoom can be set to max out at 25x or 700x. Needless to say the
700x looks like a blurry blancmange! Normally we steer clear of digital
zooms, but the picture does stay reasonably vivid up to 25x so set this as
the maximum. Of course we don't have to zoom this far, but it's
available if needed.
Scene mode - The camcorder has five program
exposure modes, the only effective one seemed to be low light mode, the
others either over exposed or caused focusing problems.
Other settings - We decided to try out the manual
overrides for exposure, focus and white balance, the colour night view,
backlight mode, AGS, Quick Start and others during live usage.
Digital stills settings and quality
The hybrid nature of the camcorder with a built-in 3.1 megapixel digital
stills camera was a big influence in our buying decision, so we experimented
with this fully. We took pictures of the same mixed scene at various
settings from the basic 640x480px (0.3mpx) to 2048x1512px (3.1mpx) and the
two JPEG compression settings. Our mixed scene on a sunny summer's day
looked across a road and included, er, the road, trees, grass, a car, a brick
wall and a house with name sign. Not very exciting, but a good
test. We analysed the resulting images on the computer.
Initially the images looked good on screen at all settings except the
lowest, especially with the higher compression. However, in reality you
wouldn't take pictures at 640x480px unless for emailing. All the images
looked a little over-exposed (taken on auto exposure) on our gamma calibrated
system. Closer inspection revealed a drop off in quality across our
images as you would expect dependant on the quality settings. We then
zoomed in and started finding problems. Even on the highest possible
quality setting there was a lack of definition, with highlights bleached out
and shadow areas with no detail. We couldn't read the well-lit house
sign. Further, we noticed a speckled effect (image noise) on areas of
solid colour, such as the blue sky. In case we were expecting too much,
we took the same scene on our ageing 2 megapixel camera and compared.
The 2 mpx image (file size 756KB) was rather better than our 3.1 mpx (1324KB)
one, none of the highlight/shadow issue, it was sharper, better exposed and
no speckling was evident on the sky. Even the house sign was almost
readable! This result was disappointing and didn't correspond with the
good reviews in the magazines. Now we know 3.1 mpx hardly sets the
pulse racing these days, but it should be better than this! Hmmm...
Now you may wonder why we haven't displayed our images on this page to
demonstrate our findings. At the time we were so disappointed we
deleted the images, in any case web images are much smaller and highly
compressed so the effects wouldn't be seen anyway. However, we do have
plenty of images taken with the camera among our Somerset
holiday images and across our post June 2006 image
gallery pages.
In conclusion we set the camera to the highest possible quality, 3.1 mpx
and minimum compression. As with video media, data storage is cheap and
plentiful and more pixels means more headroom for image manipulation
later. We archive our digital images to CD-R and so re-use the SD
cards. Incidentally, only basic EXIF information is embedded in the
JPEG files unlike a dedicated digital camera.
DV Video quality
In contrast to the stills quality we had no such problems with video,
more on this next...
We have a number of video clips available to view where referred to in the
following text.
In
use on holiday
So off to Somerset then, and with some trepidation after the poor digital
stills results. On our first day we used the camcorder visiting Street
and Glastonbury. The joystick controls the often needed functions
while the menu button the less used ones. In use the controls fall
readily to hand which makes it a doddle to make changes when out and
about. Switching between video and stills was just a click on the mode
dial. The camera can save digital stills to card during videoing or playback,
but only at 640x480px resolution - adequate to prepare web images but not for
print. As we prefer not to risk spoiling our video by trying to
multitask (even Belinda has a problem and she's a woman!), we tried saving
some stills from video later. The image shown here - Mike doing a
gorilla impression(!) outside the Information Centre in Street - was obtained
in this way as were others in our Somerset image gallery (identified by a
letter appended to the file name, eg 'b', 'c').

Problems with light
On day two we toured the Fleet Air
Arm Museum and several problems manifested. The mixed 'effect
lighting' inside the museum caused the auto white balance to get confused
and we resorted to setting it manually. No great sweat, but
Belinda's Canon digital camera had no such problem. The bigger issue
was with low light. We found the Panasonic just couldn't take a
decent still picture under lighting which was not a problem for the
Canon. We tried using the low light setting and backlight
compensation, but with only partial success. Analysing the images
after we came home it transpired that it couldn't set a shutter speed
lower than 1/50th and after it ran out of iris it increased the video
gain, and for gain read grain! Not looking good for the digital
stills again then! We can enhance our images on the computer of
course, but it's better to take good ones in the first place. Our Fleet
Air Arm video clip demonstrates the video performance in the museum.

Every night at the cottage we assessed the battery charge situation.
We were finding one fully charged battery would last the day out, despite
using the power zapping LCD screen. A typical day's use for us involved
taking around 40 stills and collecting around 15 minutes of video with
perhaps twice that time (30 mins) spent in rec standby. No complaints
about battery life then! Another good point was the ability to play our
footage back in camera with sound as there's a miniature speaker. Then
it could be set to locate the next sequence of unrecorded tape ready to
continue shooting using the blank search feature.
Problems
with wind (and it wasn't the curry the night before!)
We walked across the Brean Down
peninsula to an old fort on a hot, sunny but windy day. It was no
problem using such a small and light camcorder under those conditions and our
footage was excellent visually. Later
playback would show the auto-focus to be quick and decisive and the complete
lack of handling and camcorder operational noise (our fingers on the camera
and motors running) was a refreshing change from our previous video cameras.
However, we discovered just how good the mic was at picking up wind noise, it
often blew away our commentary (see our Brean
video clip) and this despite the wind cut filter on! Back to the
good points though, the LCD screen can be twisted round 180 degrees and this
enabled us to capture ourselves on the beach enjoying an ice cream after the
walk. Yum!
No problems with shaking
Now Mike makes out he's not a steam buff, but he did spend a lot of time
filming the steam train on the West
Somerset Railway! The OIS (Optical Image Stabiliser) came into its
own here - on the old train it effectively reduced the inevitable camera
shake (WSR video clip). Just
got to sort Mike out now then!
The
Cheddar Gorge Caves proved a severe
test of the camera's low light and colour balance capabilities and tended to
confirm our earlier findings. Of course we can use the built-in flash,
but this only illuminates a few meters in front of the camera and rather
spoils the moody cave lighting. We tried out the colour night view (it
sets a 1/2sec shutter speed) and while it allowed us to capture well exposed
video, any movement either with the subject or camera caused a severe ghostly
effect (Cheddar video clip). This
ruled out camera panning or people movement in the shot, an impossibility at
a tourist attraction! The colour night view setting doesn't extend to
digital stills unfortunately, if it did this would help with the photo's
exposure problem.
We thought the camcorder had developed a fault when it stopped while
filming the vertical Gorge face, it took a while before we realised the AGS
(Anti-Ground Shooting) was cutting in. It seems this feature prevents
filming when aiming up as well as down! After this we left the AGS off
as it spoiled our shot!

The Power LCD button was useful in bright sunshine.

Beeping and zooming
Our hot climb up to the top of Glastonbury
Tor in the bright sunlight caused us to use the Power LCD
button. This increases the screen brightness and proved very
effective at enabling us to see the LCD in the direct summer
sunshine. After the hot climb down we visited the Chalice
Well Gardens and it's such a silent, peaceful place we were
embarrassed by the various beeps and shutter effect noise made by the
camcorder. The ability to switch them off in the menu was a godsend
here!
Later
still we looked round Glastonbury Abbey
and tried the zoom mic, zooming in on a tour guide in the middle distance
taking a group round - see final video
clip. Although the sound did appear to close in, the reduction
in quality was quite objectionable. In fact, the sound proved a
little disappointing generally as it lacked stereo separation - what the
audiophiles would term soundstage. We've experienced better from our
previous video cameras.
|
To finish on a good point though, the proportional zoom was
excellent. It allows a variable zoom speed dependent on the pressure
applied to the lever. Have to be careful not to suddenly change
pressure and hence speed half way through a zoom though.
Any other points
We've not covered or tried all the features offered by the Panasonic
NVGS280 camcorder. For instance it has a continuous photoshoot, but
this is of little interest to us as the images can only be captured at the
lowest picture size of 640x480px. Similarly the Quick Start is of
little interest as we rarely need to film instantly.
We did try the self-timer, flash red eye reduction, fade in/out and the
remote control which all work as expected. We also tried the manual
settings, particularly using the shutter/iris to reduce the digital stills
exposure as on auto it tends to over-expose outdoors. The manual focus
is so imprecise to use we try to avoid it, but fortunately the auto focus is
decisive so there's no need anyway. The only time it's been needed was
when trying to shoot through fence netting at Monkey
World, the auto tended to focus on the netting and not the monkey beyond.
We've not loaded the supplied PC video editing software. It's not Mac
compatible and looks fairly basic, but our existing editing suite is
undoubtedly better anyway.

Overall conclusions
While the Panasonic NVGS280 digital camcorder packs in an excellent video
performance, no way can the same be said with its digital stills
abilities. The photos taken by this hybrid model just don't cut the
mustard. We later had an opportunity to try out the higher end NVGS500,
with 4.1 mpx stills and we saw the same defects. So this looks like a
general failing of the model series. At the end of the day, we feel
hybrid camcorders are predominately a video camera and the incorporated
digital stills camera a poor value 'bonus'. Hmmm...
Not all is rosy with on video side however. The sound can disappoint
with its lack of stereo effect and poor wind cut abilities. This would
more than likely be resolved by using an external mic clipped onto the
accessory shoe, although this makes it all more cumbersome to carry around
for casual use.

video clips taken with the camcorder.
Update - one year on. Living with our
digital camcorder
So how do we find the Panasonic NVGS280 digital camcorder now after
living with it for the past year? In fact we didn't use it during the
winter months (Nov-Mar) except to capture some digital still from our 1999
and 2000 holidays' DV tape to create our Peak
District and Yorkshire image
galleries.
We've discovered a few more camcorder quirks. One such is the
digital stills, no, not the image noise this time but the image size which is
slightly wider than the 4:3 aspect ratio. Not really a problem, but it
does mean we have to crop our web images to our 240x180px size rather than
just set the pixel size. The aforementioned picture noise remains,
however this doesn't seem to manifest itself when printing or with our web
images. The digital stills also seem to exhibit an over saturated
green/yellow (confirmed by looking at the histogram). While on the
subject of the digital stills, the over-exposure on auto continues to be an
issue. We've taken to switching to manual and knocking it down by a
stop, however this extra fiddling means we risk missing shots. Worse,
we then forget to switch back to auto-exposure, the manual setting is
retained next time we use the camera (either on video or stills) resulting in
an incorrectly exposed image! Arrggh, why o why can't the digital
stills be better on this camera?
The best bit has to be the camcorder's battery charge life which has held
up after a year. Even over the non-use winter months the batteries
still retained plenty of the previous charge. The clock had lost
several minutes though. In fact the user guide warns it's not very
accurate, although subsequent testing revealed this 'inaccuracy' to be only
10 seconds a week, we think we can live with that! Another good thing
is the sound glitch we experienced between shots on LP speed seems to have
vanished.
One
annoyance is the camera's cassette housing opens quite forcefully, so much so
we've taken to damping it down with our finger (see picture) for fear
something'll dislodge and fly off! Another issue we've noticed is some
irritating lens reflections under certain lighting conditions. This
appears be caused by the ND lens filter we use, but then again the camcorder
has a screw thread for just this purpose so Panasonic presumably expect its
use. One more gripe - the LCD screen smears easily and is then
difficult to clean. This became apparent when using the video camera in
drizzle on holiday in Shropshire in
the wet 2007 (unlike the hot and dry 2006!). We dabbed the screen dry,
but it left smears that needed some firm rubbing with a lens cloth to
remove. The camcorder's LCD is made of soft material, it would be
better if it were harder like our Sat Nav screen.
Panasonic continued the NVGS280 digital camcorder model well into 2007, a
sign that it's successful. It's since been superseded by the NVGS320
camcorder with broadly similar features, according to the user guide we
downloaded from the Panasonic website. The new video camera looses the
shoulder strap and mic in jack, but gains a lens cap (wow!) and ability to
capture higher (1 mpx) resolution stills from the DV tape. The
auto/manual switch has been moved from behind the LCD screen to the top
right. We wouldn't consider this model now - the lack of a mic socket
would prevent the use of an accessory shoe external mic, a serious omission
in view of the poor inbuilt mic. Also we'd miss the shoulder strap
which forms a useful secondary security method, as we discovered when the
hand strap broke on a camcorder in the early 90s, the camera being saved from
a watery grave by having the shoulder strap on!
Hmm, more gripes than likes. Perhaps we've outgrown consumer
products and should consider semi-pro models...
