Kodak EasyShare V705Dual Lens (available
in Pink, Silver and Black models)
IMAGE QUALITY
The Kodak EasyShare V705 Dual Lens is
a digital camera targeted to Point-and-Shoot (P&S)
photographers. It has 7.1 megapixel resolution,
a Schneider-Kreuznach C-Variogon 39-117mm (35
mm equivalent) 3x optical zoom lens, and an ultra-wide
angle 23mm (35 mm equivalent) fixed-lens for wide
landscape vistas.
We find the overall image quality of the Kodak
V705 to be good to very good with low noise at
ISO 50, but we would have preferred images to
retain more details. Image compression is quite
high producing file sizes that are between 1MB
to 2MB; we've had a couple of images that approached
3MB. The Kodak V705 produces images that are rich
in colours straight out of the camera. More advanced
photographers might object to the high colour
saturation.

The Kodak V705 provides 3x optical zoom. In the
above pictures, we show the coverage for 39mm
and then 117mm (35mm equivalent). It takes about
3 sec. to zoom from wide-angle to telephoto. The
zooming progression is very smooth; however I
counted only 5 steps between wide-angle to tele,
and so stopping precisely at the zoom position
you want is not easy.

 |
Ultra-wide angle 23mm
(35mm equivalent) |
And above, we show why the second ultra-wide
angle 23mm lens on the Kodak V705 is such a big
deal. The area enclosed in the yellow rectangle
approximates the coverage of the 39mm. The 23mm
lens also allows you to take only 3 panorama pictures
(stitched in-camera) to cover a full 180°.
[Editor's Note: While there are other digital
cameras that have wide-angle lenses, they are
more commonly at 28mm. Two other digital cameras
that come as close to the V705 are the Nikon
Coolpix 8400 [Specs] and the Kodak
EasyShare P880 [Specs], each with a 24mm lens.]
Note that the Panorama feature does not save
the images separately but stitch them together
and saves them as one panoramic image.
Kodak bills the V705 to be 5x zoom, but it's
not all optical. Digital zoom is used to bridge
the gap between the fixed focal length 23mm ultra-wide
angle lens and the 39mm starting focal length
of the zoom lens. It's easy to verify this: go
into MENU - Setup - Digital Zoom = Off, and you
can't zoom anymore from 23mm to 39mm. We recommed
that you disable digital zoom (MENU - Setup Menu
- Digital Zoom = Off), and use the camera as a
regular 3x optical zoom with the added bonus of
a wonderful 23mm wide-angle.
The Kodak V705 has Auto (really, Programmed Auto)
mode and 20 easy-to-use Scene Modes (21, if you
count Custom as a scene mode). There is no Program
Shift available in Auto mode.
The camera also provides exposure compensation
(though, no Auto Bracketing) but no Manual White
Balance. Advanced photographers will welcome the
live Histogram which can also be displayed in
Playback mode.
Shutter speed ranges from 1/8-1/1448 sec. in
Auto mode. Slow shutter speeds from 0.5 to 8 sec.
can be manually selected (MENU - Long Time Exposure).
You can set WB but, regretably, not ISO, when
using Long Time Exposure.

The Kodak V705 can focus as close as 5cm (2 in.)
at wide-angle. AF locks precisely and fast, even
in low-light. Since the AF works on detecting
contrast changes, subjects with low contrast might
be difficult to get a focus lock in low-light.
Note that macro and AF-assist do not apply to
the ultra-wide angle lens since it is a fixed
lens and no focusing is therefore needed.
There is no AF Area, i.e. you cannot manually
move the AF Frame around on the screen to where
you want it to focus.
There are three metering modes: Multi-Pattern,
Center Weight and Center-Spot. Exposure and focus
lock are achieved thru a half-press of the shutter
release button.

As the above pictures show, the auto white balance
is not quite accurate indoors under artificial
tungsten light. It is not possible to set the
WB manually. Outdoors, under natural light, the
AWB works quite well.

You can set the ISO on the Kodak V705 from 50
to 1000. The 100%
crops above (area delimited by the white square)
demonstrate that noise at ISO 50 and 100 are under
control. Noise starts to be slightly visible at
ISO 200 and up to ISO 400 is usable. At ISO 800
and ISO 1000, the presence of noise takes the
form of coloured splotches.
[Editor's Note: Since we are most interested
in ISO when using high ISOs in low-light situations,
the above images are therefore usually taken in
a low-light situation where long shutter speeds
are necessary to correctly expose the images.
However, on the Kodak V705, Long Time Exposure
is only possible when ISO is set to Auto. Therefore,
we have used flash to obtain the above images.
If you look at the EXIF info, you'll notice that
though the ISO changes, the exposure settings
do not -- it seems that the Kodak V705 varies
the flash output instead to obtain correct exposure.]
| Chromatic
Aberrations |

We were not able to find CA in everyday shots.
An example is the high contrast picture above
where you normally gets CA among the leaves. Instead
we get highlights clipping in high contrast shots.

The Kodak V705 allows the use of a long shutter
speed of up to 8 sec. in Manual mode, therefore
allowing some limited night photography. It seems
to use ISO 50 most (if not all) of the time, probably
to keep noise levels in check. Generally, with
CCD image sensors, noise usually becomes more
prominent at slow shutter speeds. The kodak V705
has noise reduction (NR) algorithm that automatically
kicks in at shutter speeds slower than 0.5 sec.
and you'll notice a longer processing time (approx.
twice the exposure time) before the next picture
can be taken.
To test this noise reduction algorithm, we take
a low-light indoors shot using a long shutter
speed of 8 sec. The NR works quite well, though
the image appears very soft and dark (obviously
even 8 sec. is not enough).
| Long Shutter
Speed - PERFECT TOUCH Technology |

| Same picture as above but
with PERFECT TOUCH Technology applied |
To correct underexposed images as the one above,
the Kodak V705 has a PERFECT TOUCH Technology
feature that brightens the image in-camera. The
above picture is the result. Not bad, eh?
Overall, the Kodak V705 is capable of producing
good to very good image quality with good image
detail overall (though some detail loss is very
apparent depending on the subject matter). Images
also look soft. One area needing improvement is
that highlights tend to be easily blown in high
contrast situations.
The pictures in the Kodak EasyShare V705 Dual
Lens Photo Gallery page provide a good sample
of what the camera is capable of. I have provided
samples at 800x600 pixels (compressed to Quality
60/100 in Photoshop Elements) as well as the 7.1MP
3072× 2304 pixels original size. Click on
the image for the original version.
You can safely assume that most macro shots
and slow shutter speed shots required the use
of a tripod. Any image that is adjusted for levels
in Photoshop has "_adjusted" appended
to the file name (though the original sized image
is, of course, not adjusted). The navigation images
at the top are usually adjusted (levels and sharpening).
I have defaulted the image size to 800x600 pixels.
For those who have their monitor resolution set
to 1024x728 pixels, everything should snugly fit
and you should not have to scroll to see the whole
image. If your monitor is set to 800x600 pixels
resolution, start the slide show and then scroll
to the right to position the image within your
screen width. Then, press F11 (if you are using
Internet Explorer) to switch to full screen mode,
and the image should fill your screen nicely.
Press F11 again at any time to switch your monitor
display back to normal mode.

Please open and download the original size version
only if you need to and only once
to your hard drive -- and save me some precious
bandwidth. Thanks!
