Sony's Cyber-shot DSC-H1
The first Sony camera with Optical Image Stabilizer ("Super Steady Shot"),
this handsome, rugged model is quite large but boasts a 2.5" LCD monitor
with anti-reflective coating and a Sony (not Carl Zeiss) 36-432mm f/2.8-3.7
zoom. Since the DSC-H1 targets experienced shooters Sony included many analog
controls plus numerous advanced capabilities in the electronic menu. A Function
button (on the handgrip but difficult to find) reduces the need for hunting
in the menu for frequently used overrides. Considering the huge LCD screen,
I don't understand why the icons and data numerals are so small. Even
with my reading glasses, I sometimes had difficulty deciphering the data. In
other respects, the DSC-H1 is convenient and logical to operate.
It's fast, too, in some respects, with 2-second start up and virtually
no shutter lag at wide angle zoom settings in outdoor shooting. At telephoto
focal lengths, shutter lag is about average (1/2 sec). Some "focus hunting"
does occur occasionally even in bright light, so pre-focusing can be a useful
technique. (Set focus on a spot that an action subject will reach, and trip
the shutter when it arrives.) The electronic viewfinder is clear and bright
in all conditions but produces a "tunnel vision" effect. Thanks
to the large/bright autofocus-assist lamp, autofocus was highly reliable indoors
(with nearby subjects) but was very slow at the longest zoom settings.
During action photography, I was not happy with the slow (1.3 fps) continuous
framing rate and the relatively long blackout time between frames. The latter
problem made it difficult to keep a moving subject within the frame during a
series of shots. When tracking horses approaching my position, the continuous
autofocus system had some difficulty in producing sharp focus, particularly
at long zoom settings. Of course, these factors are relevant only for those
who plan to shoot fast moving subjects.
In other respects, this is a highly desirable camera with a very effective Image
Stabilizer that corrects camera shake. Especially at ISO 64 and ISO 100, the
Sony DSC-H1 can make superb images with very rich colors (including stunning
reds), snappy contrast, warm skin tones, great smoothness, well-defined detail,
and very high sharpness. Only ISO 400 is disappointing, with an over-aggressive
auto noise reduction system making the images appears soft or plasticky, a problem
in prints larger than 5x7". The DSC-H1 is also compatible with an optional
tube for mounting 58mm filters and tele or wide angle adapters, accessories
that are useful for increasing its already great versatility.
Conclusion
A superzoom camera is not the ideal all-purpose model. Particularly for those
who often shoot indoors, or in other low-light situations, digicams with shorter
zooms and optical viewfinders would be preferable. Note, too, that only one
of the cameras tested features an 8-megapixel sensor while the others are 5-megapixel
cameras. (The new DiMAGE Z6 will raise Konica Minolta's ante to 6 megapixels.)
Meanwhile, an increasing number of digicams (of other types) are available with
7-, 8-, or 9-megapixel sensors. Admittedly, you don't need ultrahigh resolution
if you rarely make (or order) 8.5x11" prints, the most popular "large"
size.
For wildlife or action-photography enthusiasts, digital SLR systems are preferable
because of their greater versatility, speed, and more reliable tracking focus
systems. On the other hand, an SLR plus telephoto zoom lens is substantially
larger, heavier, and more expensive. For some photographers and for family photographers,
one of the superzoom cameras with Image Stabilizer would be a far more practical
alternative. Any of the models tested should let you get frame-filling photos
at the zoo and it will allow you to capture some nice pics of your children
on the baseball diamond or football field.
Pushing The Envelope: Panasonic Combines 8 Megapixels And 12x Zoom
Until the summer of 2005, not a single superzoom camera was available with a
sensor featuring more than 5-megapixel resolution. Most industry observers believed
that 5 megapixels was optimal in this category. Much higher resolution was possible
of course, but would require more sophisticated optical and sensor technology
to produce high edge-to-edge sharpness, great highlight and shadow detail as
well as fine ISO 400 quality. Then Samsung released the 8-megapixel Pro815 with
a 28-420mm zoom. (Since that model does not include a stabilizer, I did not
test it.) Two months later, Panasonic released the 8-megapixel Lumix DMC-FZ30
with built-in 35-420mm f/2.8-3.7 zoom and MEGA Optical Image Stabilizer.
Among the five cameras tested, the Lumix DMC-FZ30 was the most impressive, generating
beautiful images at all apertures and focal lengths. Shadow and highlight detail
are also very good, although the images are quite contrasty. The automatic noise
reduction system does produce a slight loss of the most intricate detail at
ISO 400. Still, the 8-megapixel Lumix FZ30 produced the best results of all
cameras tested at ISO 400.

There are several reasons for this impressive result, starting with higher
resolution, a slightly tweaked Venus Engine LSI II, and the new Leica-designed
"VARIO-ELMARIT" lens. The latter incorporates three aspherical plus
one ED (low dispersion) element. These are important but sensor size has also
been increased, from 5.76x4.29mm to 7.18x5.32mm. Consequently, the engineers
were not required to cram eight million miniscule photosites (pixels) on the
sensor. The larger size allows for greater light sensitivity and dynamic range
(highlight/shadow detail) and less digital noise (colored specks caused by electronic
interference) in shadow areas.
Granted, many other 8-megapixel cameras (with shorter zoom lenses) employ a
larger 8.8x6.6mm CCD made by Sony, with even larger photosites. Even so, the
Lumix FZ30 produces surprisingly fine image quality at ISO 400, probably due
to the other reasons mentioned earlier.
