The Canon PowerShot SD870 IS Digital ELPH ($399) is an ultra-compact
camera with a wide-angle lens, huge 3-inch LCD display, and all the bells and
whistles that you'd expect on a point-and-shoot camera in 2007. The SD870 is
sort of a combination of the SD750 (for the LCD) and the SD800 (for the wide-angle
lens), though that's not "official".
Canon's model numbering is so confusing that I decided to
make two charts to help you make sense of it. First up, we have a Digital ELPH
family tree:

Canon's official line is that the SD870 is the replacement
to the SD800, though as I mentioned, it takes cues from the SD750 as well.
Now, here's a look at how the various Digital ELPH models
compare:

The biggest changes on the SD870 compared to its predecessor
include a higher resolution sensor (of course), a larger LCD, enhanced face
detection, and in-camera redeye removal. Unfortunately, the optical viewfinder
disappeared along the way.
I was a big fan of the PowerShot SD800. So much so, in fact,
that I bought one for myself. Is the SD870 a worthy successor? Find out now
in our review!
The PowerShot SD870 IS is known as the Digital IXUS 860 IS
in some countries.
What's in the Box?
The PowerShot SD870 has an average bundle. Inside the
box, you'll find:
- The 8.0 effective Megapixel PowerShot SD870 IS Digital
ELPH camera
- 32MB Secure Digital memory card
- NB-5L lithium-ion battery
- Battery charger
- Wrist strap
- USB cable
- A/V cable
- CD-ROM featuring Canon Digital Camera Solutions
- 241 page camera manual (printed)
Canon is one of the few camera manufacturers who still includes
a memory card in the box, instead of building it right into the camera.
The 32MB SD card that comes with the SD870 won't hold many photos (eight, to
be exact), so you'll want a larger card right away. The camera supports the
SD, SDHC, MMC, and MMCplus memory card formats, and I'd suggest starting out
with a 1GB card. It's worth spending the extra money for a high speed SD or
SDHC card.
The SD870 uses the same NB-5L lithium-ion battery as its predecessor.
This battery has 4.1 Wh of energy, which isn't bad for a camera of this size.

You can figure out who the SD870's main competitor is just
by looking at that chart -- it's the Panasonic Lumix DMC-FX55. It's this same
camera that just edges out the SD870 in terms of battery life. Don't worry
too much, though -- the SD870's numbers are still 27% above average.
I should mention a couple of "gotchas" regarding
the proprietary battery used by the SD870 (and every other camera on that list).
For one, they're fairly expensive -- an extra NB-5L will set you back at
least $40. Secondly, if that battery dies, you can't use an off-the-shelf battery
like you could on a camera that uses AAs. That said, you won't find a camera
this size that uses anything else.

When it's time to charge the battery, just snap it into the
included charger. This is my favorite type of charger: it plugs directly into
the wall. It takes around a little over two hours for a full charge.

Like all ultra-compact cameras, the SD870 has a built-in
lens cover, so there's no lens cap to deal with.
There are just a few accessories available for the PowerShot
SD870. The most interesting is probably the WP-DC17 underwater case ($185),
which lets you take the camera up to 40 meters below sea level. Next we have
the HF-DC1 external slave flash (priced
from $90), which attaches via the tripod mount and fires when the onboard
flash does, giving you more flash range and less redeye. Last, but not least,
we have the ACK-DC30 AC Adapter (priced
from $45), which lets you power the
camera without draining your battery.

CameraWindow in Mac OS X
You'll find version 31 of Canon's Digital Camera Solutions software inside the SD870's box. Canon has given their software a refresh, with the
ImageBrowser (Mac) and ZoomBrowser (Windows) products now up to version 6.
The Mac version is now Universal, so it runs at full speed on Intel-based Macs.
The first part of the Browser software that you'll probably
encounter is Camera Window, and you'll use it to download photos from your
camera.

ImageBrowser in Mac OS X
Once that's done you'll find yourself in either ImageBrowser
or ZoomBrowser, depending on your computer. Here you can view, organize, e-mail,
and print your photos. If you categorized any photos on the camera (more on
this later) then that information is transferred over to the Browser software.
ImageBrowser edit window in Mac OS X
Double-click on a thumbnail and you'll bring up the edit window.
Editing functions include trimming, redeye removal, and the ability to adjust
levels, color, brightness, sharpness, and the tone curve. There's also an auto
adjustment option for those who want a quick fix.

PhotoStitch in Mac OS X
A totally separate program called PhotoStitch can, well, stitch
together separate photos into one giant panorama. The interface is simple,
the process takes minutes, and the results are impressive, as you can see.
You can use the SD870's Stitch Assist feature to line up the photos side-by-side
with just the right amount of overlap.
Canon has combined the Basic and Advanced manuals from previous
PowerShots into a single, thick book on the SD870. The manual is quite detailed,
with every feature and option covered. At the same time, it's not terribly
user friendly. Still, as camera manuals go, it's better than most. Canon also
includes separate manuals describing direct printing and the software bundle.
Look and Feel
The PowerShot SD870 really is a combination of the SD750
and SD800 in terms of design. It has the shape and size of the SD800, and the
glossy black backside (and 3-inch LCD) of the SD750. It's a very compact (but
not tiny) camera made of a mixture of plastic and metal. It's generally well
put together, save for the flimsy plastic door over the memory card/battery
compartment and a plastic tripod mount.
Ergonomics are pretty good. The camera is easy to hold with
one hand, and the most important controls are right where you'd expect it.
I didn't care for the size of the four-way controller, nor the fact that my
right thumb ended up resting on it.

Like some of the other ELPHs, the SD870 comes in two "trims" --
silver and black.
