Canon Powershot A640

 

Canon is definitely one of the most respected names in the consumer digital camera market segment. The common belief is that you can't really go wrong with purchasing a Canon camera. Though I may not agree a hundred percent with that, I do know that...

In the end, the only complaints I have with the Canon A640 are mere nitpicks. The camera does everything it sets out to do and makes it easy. It has fun features for the more casual users, and it has enough manual settings to give a serious...

PowerShot A640

 

The Canon PowerShot A640 was introduced this fall as a 10-megapixel prospect for the holiday season. It replaces the 7.1-megapixel Canon A620 and is the first A-series camera to include a whopping 10 megapixels. The PowerShot A640 has a Digic II image...

Flip out LCD monitor with wide view ; Flash exposure compensation ; Only 10 MP compact cam with manual controls ; 4x optical zoom lens ; Manual controls ; Great movie mode

High noise levels ; Slow start-up and operation- Inaccurate viewfinder ; Only 115k on LCD ; Barrel distortion ; Heavy and clumsy camera body ; Expensive $399 price

The PowerShot A640 has more pros than cons. It has a lot of resolution at 10 megapixels, but that won't be necessary for most users of this camera. Point-and-shooters won't need to create life-size prints since most will make small prints with an...

Canon PowerShot A640 Camera

 

The versatile A640 caters to the auteur and amateur alike by cramming DSLR features into a point-and-shoot body. Continuous shooting, manual aperture and

Flip-out, 2.5-inch LCD can be angled to snap over crowds. Movie mode shoots at 30 frames per second. Included A/V cables for big-screen connectivity. Can shoot underwater with optional case. AA batteries means never having to wait for a charge

Not super portable at 4.3 x 2.6 x 2 inches and 12 ounces. Bundled with a rinky-dink and borderline useless 32MB memory card

Canon PowerShot A640

 

The PowerShot A640, launched in August, just before Photokina 06, replaces the popular A620 at the top of Canon's increasingly well-specified 'budget' A series range. The new model gets a bit of a facelift (and a new coat of black paint) as well as a...

Very good resolution, very clean results at lower ISO settings ; Bright, but natural colors ; Excellent handling ; Decent edge-to-edge lens performance ; Useful 35-140mm equiv. 4x zoom lens with decent F2.8-4.1 max aperture range ; Reliable focus in...

Clipped highlights in bright, contrasty conditions (not helped by high default contrast) ; Focusing at tele end in low light can hunt ; Zoom is not very smooth - only 7 steps from wide to tele ; No ISO button - WB, drive, metering etc only accessible...

Canon is one of the few companies still producing solid photographic feature-rich compact cameras like this, offering a genuine alternative for the serious photographer on a budget wanting SLR-level control.

The PowerShot A640 and A630 digital cameras are equipped with high resolution 10.0 and 8.0 Megapixel CCDs respectively. Both cameras feature the same body design, high-quality Canon 4x Optical Zoom lens, optical viewfinder as well as a 2.5-inch...

The A640's most striking feature is its pivoting 2.5-inch LCD. You can flip and twist it to help frame odd-angled shots or fold it against the camera for a more traditional feel. It's a handy feature, as the screen can tilt up for shooting at chest...

Lots of manual controls; flip-out LCD; accepts accessory lenses.

Noisy at ISO 800; no image stabilization.

It's not great in low light, but the A640 has plenty of features photographers will love.

Canon PowerShot A640 Digital Camera - Hands-On Preview

 

The Canon PowerShot A640 couples a 10 megapixel CCD imager sensor with a 4x optical zoom lens that offers a 35mm-equivalent focal range of 35 to 140mm. That's a moderate wide-angle that reaches to a somewhat more generous telephoto than you'll find on...

Excellent value for the money ; Bright, attractive color that stops short of seeming overdone ; Good skin tones ; Auto white balance handles a wide range of lighting well ; Better than average exposure accuracy ; Good lens, generally low distortion and...

Inaccurate optical viewfinder ; Flash vignetting in the corners at wide angle ; Too many manuals to find what you need when you need it ; Auto rotation not recognized by many other standard applications

Canon PowerShot A630/A640

 

The PowerShot A630 and A640 are two lower priced cameras that offer the manual controls and expandability usually reserved for more expensive cameras. Both cameras feature 4X zoom lens, a rotating 2.5" LCD display, a VGA movie mode, and unlimited...

Very good photo quality, noise levels stay low through ISO 200; ISO 400 still usable too, especially on the A640 ; A bit more zoom than your typical camera in this price range ; Large 2.5" LCD can flip out and rotate; screen is visible in low light ;...

Redeye a problem ; LCD resolution isn't great ; Current zoom setting not shown on LCD ; Can only record about 8 minutes of VGA video due to 1GB file size limit ; Plastic tripod mount; can't swap memory cards while camera is on tripod ; Included memory...

The Canon PowerShot A630 and A640 are two very capable digital cameras that are suitable to beginners and advanced users alike. They offer far more than most cameras in this price range, which is why they earn my enthusiastic recommendation. I would...

Canon PowerShot A640

 

Newer digital cameras offer more resolution than ever and, with a whopping 10 megapixels, the Canon PowerShot A640 is at the high end. Besides its high resolution, the A640's features are fairly standard. Like most Canon A-series cameras, the A640 has...

Product Specifications

The PowerShot A640 bursts with creative options. Use its 10.0 Megapixels to shoot poster size prints with fine detail. Discover new possibilities with the vari-angle LCD and optional accessories. Print high quality poster size images with all the incredible detail of 10.0 Megapixels. Crop and trim to create new compositions while keeping your photos extra large and razor sharp. A 4x optical zoom lens gives you the flexibility to frame shots up close or at a distance without sacrificing quality. The large 2.5" Vari-angle LCD twists in all directions - ideal for self-portraits and creative shots at unusual angles. Night Display mode aids visibility in low light while a selectable Grid Line display helps with composition. A useful 3: 2 ratio overlay indicates the printable area for standard photo prints. Canon's DIGIC II image processor manages all camera functions and processes images at high speed for excellent responsiveness and extended battery life. iSAPS is a built-in assistant that uses scene information to optimize camera settings before the shot is taken. Rely on 9-point AiAF to keep even off-center subjects sharply in focus or use FlexiZone AF/AE to manually select a focus point. 21 shooting modes include a full creative zone for manual control and 10 Special Scene modes for tricky lighting conditions including Snow, Beach and Underwater. My Colors allows color effects to be applied to images and movies. A high-speed ISO 800 setting allows you to shoot correctly exposed images in low light conditions without using a flash. ISO 800 also enables shooting at higher shutter speeds reducing the risk of image blur. Safety Zoom offers extra zoom magnification without affecting image quality. Use the Digital Tele-Converter for extra reach on every shot - just like adding a teleconverter lens to the camera. Focus as close as 1cm and capture all the intricate detail of tiny subjects. Shoot extra long 30fps VGA quality movies with full audio. View them on the camera's LCD screen or connect to a TV or PC for full screen playback.
