Now that compact cameras are so light, it's actually made shaky images
slightly more likely in even bright light.
Pentax has faced up to this in its latest snazzy snapper, the
A30,
by including three anti-shake systems.
First, there’s the sensitivity option – it's nothing to do with being in
touch with your feminine side; this is the way the sensor automatically responds
to available light. By increasing sensitivity (the ISO setting) it’s possible to
make the shutter speed faster, thus reducing the possibility of camera shake.
Pentax calls this feature Digital SR. It adjusts the ISO up to a maximum of
3200, which is remarkably high, although it can only reach these heights when
the images are set to five megapixels, not the full 10-megapixel resolution the
camera can manage at lower ISO settings.
Secondly, the sensor itself is able to move. So if you shake the camera, the
sensor compensates for this by quickly shifting in the opposite direction in
order to stabilise the image. And third, there’s a shake-reduction feature for
when you’re shooting movies instead of still images, which compensates
electronically rather than mechanically, using the included software.
All of this comes at a price: with higher ISO settings image
noise
is often an issue and certainly here there’s plenty of that in all but the
brightest of light. The reason for much of this disappointing performance is the
10-megapixel sensor. While that many dots may sound alluring, the sensor is not
physically large enough to have to draw in enough light to prevent the resulting
image noise.
That aside, there’s a face-priority function which can recognise when there’s
a pair of eyes, a nose and a mouth in shot and focus on that. It’s a neat idea
that works well in the A30. This camera is also particularly compact and will
slip into the smallest pocket, as well as leaping into life satisfyingly fast
when switched on. There’s also very little trace of shutter lag, which often
bedevils less pricey cameras.
Pentax’s reputation for making solid, feature-heavy, attractive cameras while
keeping the cost down remains in place with this device – it's a snip at the
price, but it's not as accomplished as some seemingly less well-equipped models.
