Particularly in Extra Fine JPEG or raw capture, image quality is outstanding
at ISO 100-400, suitable for making gallery-quality 13x19" inkjet prints.
Photos made without overrides exhibit rich colors, snappy contrast, high sharpness,
and remarkable smoothness. Most of my friends considered the results to be "perfect"
while a couple would have preferred just a hint of a "grain" for
a more film-like effect. Switching to Raw Capture mode produced nearly identical
quality but the Sony Image Data Converter SR 2 software provided a wide range
of correction possibilities (without degrading the image), including control
over the NR level.
Auto White Balance (AWB) was very effective outdoors while multi-pattern metering
was often accurate, although some light-toned scenes required a +2/3 compensation
level. The Dynamic Range Optimizer was useful for increasing shadow detail,
but produced the most natural-looking effect when used at moderate intensity.
(When in doubt as to the optimal level, try DRO Bracketing.) In images made
at higher ISO levels, digital noise is very well controlled. Color saturation
and edge sharpness remain high even at ISO 3200; the images were suitable for
decent 8x10" glossies. (ISO 6400 is mostly for emergency use and for 4x6"
prints.) A stronger or weaker level of NR can be set in camera at ISO 1600 and
above. That allows for an even smoother effect (but with more smudging of fine
details) or for a more "grainy" look (with better definition).
The new Extra Fine Capture mode minimizes JPEG compression in order
to provide the very "cleanest" images possible, without
any noticeable JPEG artifacts. While raw capture offers a significant
benefit (great "correctability" in the Converter software),
actual image quality is just as high in Extra Fine JPEGs, a benefit
for photographers who do not want to spend extra time at a computer.

The original A100 remains a very fine 10-megapixel entry-level D-SLR but the
new enthusiast-level 12-megapixel model is even more desirable because of more
effective technology, much greater speed, more rugged construction, and a richer
feature set. It should be a strong contender in the mid-range category in spite
of fierce competition from other recent 10- and
12-megapixel models. While the A700 does not include a Live View mode, it's
a powerful camera, part of an extensive Sony system that should satisfy even
the semiprofessional photographer. Whether you already own Dynax lenses or are
considering a multi-talented, high-resolution D-SLR, be sure to ask for a demo
of the A700 while comparison shopping for your next camera.
