Canon Powershot SD980 IS
The Canon PowerShot SD980 IS is a bit of a reworking of the SD960 IS. That model's design and features were sort of a letdown. The SD980 turns things around, though, by using a wider lens with longer zoom range, a bigger and now touch-screen LCD, and some improved physical controls. Photo and video quality and performance remain very good for its class, but there's room for improvement, too. The SD980 is worth the extra money above the SD960, especially if you're interested in the touch-based controls.

Typical of the Digital Elph series, the SD980 is reasonably small, good-looking, and available in different colors--silver, gold, blue, and purple. Canon used a 3-inch wide-screen touch-screen display, which makes sense for the HD video capture, but less so for taking photos. If you shoot at the SD980's top resolution of 12 megapixels, you're left with roughly 2.5 inches diagonally of screen for your viewfinder. The only way to take advantage of the full screen for framing shots is to drop the resolution to 4,000x2,248.
For a first effort, the SD980's touch-panel controls are reasonably well executed and the screen is fairly responsive and can be calibrated to your touch. Much like Panasonic's Lumix FX500, Canon only uses the touch screen for a handful of shooting features, while a majority of its functions and menu navigation are still handled by physical buttons. And actually, if you don't want to use the touch interface, you don't have to at all. The best use for a touch screen is for focusing on specific subjects by tapping on them, which this Canon does. It also lets you quickly change scene modes, adjust exposure, and choose your flash mode. Those used to shooting with a camera phone might appreciate the onscreen shutter release that you can set to appear whenever the camera is turned vertically.
In Playback mode, the touch screen can be used for flipping through or scrolling between images, selecting photos to delete or mark as favorites, starting a slideshow, and magnifying a section of a photo by tapping on the part you want to see more closely. Canon also includes its Active Display technology letting you move back and forth between photos, playing and pausing videos, and checking focus on still images by tilting the camera. Don't want to use either of those methods for playing photos? You can always use the buttons and navigation dial.
All of the SD980's physical controls closely resemble those on the SD960, except for the directional pad/scroll wheel, which is similar to the one on the SD880. The combination works well together so that even if you decided to use the buttons instead of the touch screen, shooting, playback, and menu and setting navigation are all easy.
General shooting options Canon PowerShot SD980 IS
ISO sensitivity (full resolution) Auto, 80, 100, 200, 400, 800, 1,600
White balance Auto, Daylight, Cloudy, Tungsten, Fluorescent, Fluorescent H, Custom
Recording modes Auto, Program/Scene, Movie
Focus modes Face AF, Center AF, Touch AF, Macro, Normal, Infinity
Metering Evaluative, Center-weighted, Spot
Color effects Vivid, Vivid Blue, Vivid Green, Vivid Red, Neutral, Sepia, Black & White, Positive Film, Lighter Skin Tone, Darker Skin Tone, Custom
Burst mode shot limit (full resolution) Continuous unlimited
The SD980 is limited to three shooting modes and none of them allows you to tweak shutter speed or aperture; it's very much a point-and-shoot. A small switch on top moves you between Canon's put-it-there-leave-it-there shooting mode called Smart Auto; a Program/Scene mode option; and a Movie mode. The Smart Auto picks from 22 different scenes, so the bases are well covered. In Program you can control things such as ISO, white balance, light metering, and exposure compensation or you can switch to a handful of scene options like Portrait and Indoors and Specialty Scene selections including Aquarium, Long Shutter, and ISO 3,200. The Movie Mode lets you capture clips up to 10 minutes in length at an HD quality of 720p and the results are very good. (For quickly connecting to an HDTV, there's a miniHDMI output behind a small door on the right side of the body.) But sadly, the 5x optical zoom doesn't function while recording. The optical image stabilization does, however.
If you're the type to get impatient waiting between shots, the SD980 might disappoint you with its 3.1-second shot-to-shot time; turning on the flash drags that out to 4.5 seconds. Also, there's no burst mode on this model, just continuous unlimited shooting capable of 0.6 frame per second. Start-up time is decent, however, at 1.6 seconds and shutter lag is OK, too: 0.5 second in well-lit conditions and 0.8 in more challenging dim light.
As with most compacts, photos are best from the SD980 at ISO sensitivities below ISO 200. At ISO 400, fine detail starts degrading as shots turn less sharp, more smooth, and fuzzy. For a majority of my testing the camera remained in Canon's Smart Auto mode, which was really reliable at picking the correct scenes, but plays things safe by going with higher ISOs. At the two highest full-resolution sensitivities--ISO 800 and ISO 1,600--noise/artifacting and softening from noise suppression are both visible, but the balance is good so all detail isn't lost. However, there is some color shifting and yellowing, which makes shots at ISO 1,600 of questionable use.
Color, white balance, and exposure are generally very good at ISO 400 and below, though highlights have a tendency to blow out--typical of compact cameras. Despite the wide-angle lens there is little barrel distortion at the lens' widest position and no discernable pincushion distortion when the lens is fully extended. Photos exhibit an average amount of purple/blue fringing in high-contrast areas. Depending on the shot there is a chance it will be noticeable at print sizes of 8x10 inches and above.
The PowerShot SD980 IS is Canon's first attempt at a touch-screen interface for a Digital Elph and it feels like it. That's not necessarily a bad thing because the result is a camera with useful touch-based functions that doesn't completely abandon comfortable, familiar physical buttons. The SD980 lets you get a touch-screen camera and decide for yourself whether you want to use it without the fear of having to use it.

Self Portraits
Compact and practical, digital cameras have become a primary feature on many modern cell phones. First introduced commercially around 2002, camera phones allow users to take (and share) photos quickly, easily, and unobtrusively. While this is highly convenient for many, the availability of such powerful technology does raise certain privacy concerns.
The near-omnipresence of these devices has had a profound social impact, as taking someone's photo is no longer an easily identifiable act. Camera phones allow people to take photos without drawing attention to themselves, as they may appear to be talking, browsing the Web, or otherwise merely using their phone. With such information so easily gathered, shared, and sometimes made public, an impact on privacy is inevitable.
One can travel all over the world and one of the most common used technological devices besides cellphones and laptops are digital cameras. It is a device that connects people of different languages and countries. Citizens from all different types of cultures can comprehend this device without using language. It is a technological device that can connect the world and capture it in a photograph all at the same time.
Because of these issues, certain organizations and places have, on occasion, placed bans or restrictions on the use of cell phones. Government organizations, schools, and certain companies where personal or credit card information is viewed on a daily basis, often have outright bans on the use of camera phones. Unfortunately, such bans are very difficult to enforce, as cell phones are often small and easily hidden or disguised.
One common use of the camera is that of self photography and it allows the taking of photos that would be difficult to do in the past without someone else having access to the photos during the processing. But standing in front of a bathroom mirror witha digital camera allows you to take your own picture.
