Like its stablemate, the PowerShot A540, the compact Canon PowerShot A700 offers abundant manual controls, respectable image quality and acceptable ISO 800 performance. Either camera should appeal to enthusiast photographers or serious beginners who want some control over exposure and focus. But the A700's biggest edge is its 6X zoom lens, a nice step up from the A540's 4X glass. Plus, the A700 includes macro focusing down to 0.4 inch, a higher-resolution 2.5-inch LCD, and a rear-sync flash that fires at the end of your exposure to keep car headlights from looking like laser beams.
Design
A tad larger than the A540 at 94.5mm by 66.5mm by 43.4mm and 200 grams ( including SD memory card and two AA batteries), the Canon PowerShot A700 is easier to shoot in one-handed mode, since it's easier to shift your forefinger between the shutter and the zoom lever, both of which are mounted atop the grip. The top panel also hosts a speaker and a recessed power button with a green power LED that doubles as a position indicator for the 11-notch knurled mode dial. The dial lets you choose from the standard auto, program, manual, aperture-priority, shutter-priority, and movie modes, plus Portrait, Landscape, Night Scene, and Stitch Assist scene modes. It also offers an SCN setting to access nine other scene modes, including the unusual Colour Swap. This mode lets you exchange one colour range in your scene for another.
The small optical viewfinder is useful for framing when bright light washes out the 115,000-pixel 2.5-inch LCD.
Back-panel controls include a slider for alternating between recording and playback modes as well as a print-sharing button to mark images for DPOF (digital print order format) output. As with many other cameras, the EV button lets you adjust exposure plus or minus 2EV in 1/3EV increments. Flash options (up) and macro or manual focus choices (down) are just a key-press away. Information, such as drive, meter, and flash modes; image size and compression; exposure compensation; and shots remaining can be turned on or off with the display button.
Frequently accessed shooting options and setup features are divided between the function/set and menu buttons, respectively. Activating the two- or 10-second self-timer requires a trip to the menu, but the setting is sticky, so you don't have to repeat the process to take several pictures in a row using the timer.
Features
The Canon PowerShot A700's 6X zoom range includes a moderately wide-angle 35mm (35mm equivalent) at the short end and a respectable 210mm telephoto at the long end. Fans of close-up photography will appreciate this camera's lens, which focuses down to 0.4 inch in macro mode. Manual focus activates an enlarged central LCD area and an indicator bar at the top of the frame. Most casual users will opt for either the nine-point automatic or the selectable single-point autofocus.
Exposure choices include evaluative, centre-weighted, or spot metering. In spot mode, you can grab exposure information from the centre of the frame or from your selected focus zone. Shutter speeds range from 15 seconds to 1/2,000 second, and f-stops cover f/2.8 to f/8 in automatic, manual, program, aperture-priority, and shutter-priority modes.
Dual automatic-ISO settings let you choose between standard Auto, which includes ISO 64 through ISO 400, and High ISO Auto, which uses ISO 800 when necessary. You can also manually select ISO settings between ISO 80 and ISO 800.
Canon's My Colours option lets you shift the colours via presets including Vivid, Neutral, Sepia, Black-and-White, Lighter Skin Tone, Darker Skin Tone, and Positive Film, which mimics film colour transparencies, plus a user-definable Custom Colour mode.
As with other A-series Canon PowerShot cameras, optional 1.75X telephoto and 0.75X wide-angle lenses as well as a 52mm filter adaptor can fasten to a bayonet mount around the lens. A plastic collar covers the mount when not in use. Canon also offers a beefier HF-DC1 flash, which fits on a bracket that screws into the tripod socket and fires as a slave in cordless mode.
Performance
Low shutter lag, fast response, the available shutter-priority mode and a speedy but limited burst mode make the Canon PowerShot A700 a decent choice for fast-moving action and sports. Its speedy autofocus system snapped off a shot under bright, high-contrast lighting a mere 0.4 second after we pressed the shutter, while it took just 0.7 second under low-contrast illumination with the red focus-assist lamp. Continuous-shooting mode clocked 2fps regardless of resolution or compression, with seemingly no limit to the number of shots.
That's not the only thing fast about this camera. It powered up and grabbed a first shot in 1.8 seconds and turned in shot-to-shot times of 2.1 seconds after that. Activating the flash slowed between-shot pauses to 4.9 seconds in our tests. Red-eye-prevention mode only partially tamed red pupils in our test subjects. The flash displayed roughly average power for cameras in this class, providing even illumination out to 11 feet at the wide-angle setting with ISO set to auto but only seven feet when the lens was zoomed out to telephoto. We occasionally saw ghosting when framing with the LCD, but it did a fine job of gaining up to maintain visibility under low light.

Image Quality
We liked the Canon PowerShot A700's images, which were very similar to those of the less expensive A540. Metering in both cameras sacrificed detail in highlights in order to preserve detail in shadows, both had well-saturated colours and neither had much noticeable purple fringing. The A700 produced slightly more neutral flesh tones than did the A540, plus its automatic white-balance systems kept colours pure under both daylight and incandescent light.
As you might expect, since both cameras feature the same sensor as well as Canon's Digic II image processor, they had similar noise performance. Noise was low at ISO 80 and increased noticeably at ISO 400. While noise was more abundant at ISO 800, images were still usable.
Canon's A700 is versatile. Optional accessories let the camera grow with you and, along with the camera's many manual controls, make the Canon PowerShot A700 a decent choice for anyone who wants to learn more about photography while reserving the right to go fully automatic when needed. However, if you think you can settle for a 4X zoom instead of the A700's 6X lens, then you may want to consider Canon's own A540 and put the cash saved toward accessories.

Good Compact Flexible Camera
Although I have owned 'Normal' (Film) Cameras - both SLRs and 'snapshot style' Cameras - and have used other peoples Digital Cameras this is the First Digital Camera I have owned.
I was shopping for a Camera with the following capabilties:
Decent optics (6x was actually the minimum zoom I was looking for however this camera appeared to be the best option in the Price range I had).
Optical Viewfinder - I have yet to see an LCD display on a Camera that is clearly viewable in direct sunlight. So I wanted a Camera with a regular, optical Viewfinder.
easy to use - My wife can be somewhat intimidated by the more upmarket cameras and it had to be a Camera she was comfortable with using - this Camera met this Criteria nicely.
Low shutter Lag - If you point and shoot then the Camera will suffer some apparent Lag while it Focuses also in lower Light Situations the Camera does not appear to charge the flash until you press the shutter.
In both of these Situations the Lag can be reduced significantly by half pressing the button - this will pre focus the Camera and charge the flash (if required) and after this point the shutter lag becomes insignificant.
Macro Focus - I often need to photograph Electronic circuits/Faults/assemblies so I needed a Camera with Macro capability - This leads to what is probably my biggest gripe with the Camera images taken using Macro focus come out curved - particularly towards the edges of the Picture - This would probably not be noticeable when taking pictures of objects such as flowers and insects etc however with objects with straight lines such as Circuit boards this does become noticeable.
The curvature decreases as you zoom in so the work around I have is to move the camera further away and zoom in on the subject - this usually requires the use of a Tripod which I usually use for these shots anyway
Pros: Easy to Use - even my Wife can drive it
Real Optics - the six Times zoom works well
Low shutter Lag
LCD is large enough to be useful and quite clear.
Flexible - it offers manual capability for those more 'unusual' situations
Clear Pictures in most situations
Cons: Macro images do suffer some curvature - although this can be mostly alleviated by moving the camera further back and zooming in on the subject it is trickier to find a nice distance at which the camera can focus.
The (optical) Viefinder shows less of the image than the Camera actually takes - this is actually not a major problem but may be annoying to some people.
As would be expected the LCD display shows exactly the picture the Camera takes.
