Zoom Range
Today, you’ll find cameras with 10x, 12x and now even a
boundary-busting 15x zoom. But the “x-factor” doesn’t 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 35mm—even if the latter has a longer overall
range. A 10x zoom is typical, but go with a 12x or longer if you’re
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 that’s “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. It’s 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. It’s 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., you’ll 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 size—particularly if you intend
to shoot a fair amount in the RAW format. Big files mean you’ll be
filling up memory cards—and maybe your hard drive—quickly. We’re 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 you’re 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.
