Advanced
compact zoom cameras combine extended zoom ranges, large LCDs and key
SLR-like functions into small, highly portable packages. Theyre easy
to use, easy to carry and easy on the wallet. As a class, they provide
more performance per pound than any other type of digital camera and,
thanks to innovative features like image stabilization, produce results
that rival any system.
Although zoom cameras dont have
interchangeable lenses, and therefore dont fit into the D-SLR
category, they do allow users to view the subject through the lens via
an EVF (electronic viewfinder) or on an LCD monitor. Real SLRs allow
direct viewing through an optical viewfinder, but its not possible to
preview the subject or compose the image on the LCD (with the notable
exception of the Olympus Evolt E-330).
An EVF makes it easy to
shoot in both bright and extremely dark conditions. And it allows you
to preview digital effects like color shifting, black-and-white mode
conversion, contrast adjustment and so forththe things that cant be
seen through a D-SLRs eyepiece.
Zoom Range
Today, youll find cameras with 10x, 12x and now even a
boundary-busting 15x zoom. But the x-factor doesnt tell the whole
story. Check the wide-angle specification as well as the telephoto. A
zoom range that begins at 28mm (equivalent coverage) can be more useful
than one that begins at 35mmeven if the latter has a longer overall
range. A 10x zoom is typical, but go with a 12x or longer if youre
photographing wildlife or sports. When comparing cameras, look for the
35mm-equivalent specifications, which will translate the zoom factor
into a focal-length range, such as 35-350mm for a 10x zoom.
Samsung is the current leader in the longest category with a whopping
15x Schneider lens on its Pro815 model. The Sony DSC-R1 has a Carl
Zeiss zoom thats only 5x, but it covers a range from an extra-wide
24mm to 120mm, making it the ideal choice for many situations.
Image Stabilization
Image stabilization, whether optical or electronic, is most useful when
shooting with a long telephoto. Its one feature that truly enhances
the performance of any zoom camera. But this feature will help you
achieve better results in more situations than you may at first
imagine. Its very handy in low-light conditions, when shooting macro
or at any time you want to keep the ISO setting low. If you normally
can shoot handheld at 1⁄125 sec., youll be able to drop down to 1⁄30
sec. (or so) without ending up with a soft image. Roughly half of all
available zoom cameras have image stabilization. For the other half,
use a tripod or monopod.
Resolution
These days, you have more choices than ever when it comes to
resolution. The baseline is set at 6 megapixels, and cameras like the
Sony DSC-H2 and Canon S3-IS produce outstanding results. But you can go
all the way up to 10 megapixels with the Sony DSC-R1. Keep in mind that
as resolution increases, so does file sizeparticularly if you intend
to shoot a fair amount in the RAW format. Big files mean youll be
filling up memory cardsand maybe your hard drivequickly. Were not
selling high-resolution cameras short, just pointing out that sometimes
bigger is the enemy of big enough.
If your biggest prints
are typically 8x10 inches, a 6-megapixel camera will be more than
sufficient. However, if youre interested in creating larger prints or
want the flexibility to crop into an image and still maintain quality,
a higher-resolution camera would be recommended.
LCD Size
Heres one spec where bigger is always better. A large (two inches or
more) LCD monitor makes it easier to compose, review and show images to
others. Equally important, in particular to eyeglass wearers, is that
its easier to read the cameras command menu on a large LCD. So even
if you shoot mostly with the eye-level viewfinder, youll find that a
large LCD is a good thing to have.
Handling & Portability
When shopping for any camera, especially a D-SLR or zoom compact, make
sure it fits comfortably in your hands and that your fingers fall into
logical locations. Also, you should be able to switch from using the
LCD monitor to shooting at eye level without changing your grip.
One of the main attractions of zoom compact cameras is that, compared
to heavier D-SLRs, theyre easier on the neck. Theyre lightermany tip
the scales at under a poundas well as smaller. If you want to travel
light, be sure to check the weight.
Batteries & Memory
Battery performance is seldom an issue, but the type of battery is
something to consider. Lithium-ion cells lead the popularity polls, but
rechargeable NiMH AA cells, such as those found in the Sony DSC-H5 and
Olympus SP-510 UZ, are inexpensive, commonly available and, in a pinch,
can be supplemented by high-output disposable batteries.
Similarly, consider the type of memory card your new zoom camera uses.
If you already own a D-SLR that uses CF cards, try to stick to that
type. Whichever card format you choose, purchase as big a memory card
as you can afford. This is important if youre using a high-resolution
camera and expect to save images as RAW rather than JPEGs.
