Canon PowerShot A640 Review

His screen tilted to catch sight of its original 10-megapixel resolution providing impressions tall not counting its ability to make manual adjustments Canon PowerShot A640 aircraft quite attractive.

Verdict Canon PowerShot A640
the A640 is no miracles in low-light conditions, but it offers many features that photographers will appreciate.

Fort many manual settings and a relatively modest price, the PowerShot A640 from Canon seems quite attractive. Even if it does not offer the flexibility of some cameras more upscale and n’arbore not stylish design more compact models, this 10-megapixel camera is a model elegant and rich in functionality, which presents some surprising benefits.

The most striking of the A640 is its LCD screen that pivots of 6.35 cm. It can be turned tilted to the framing in unusual positions, or folded against the aircraft for a shooting classic. It’s convenient because you can tilt the screen up to take shots at the chest, slopin g down to photograph above the crowd, or even return completely to achieve self. Canon has equipped several of its aircraft of this type of pivoting screen, including the A630 and A620, versions lowest range of the A640. The screen door was also used on many high-end models outside Canon DSLRs, such as PowerShot G6 and S3 IS. Curiously, the latest avatar of the series PowerShot G, the G7, is lacking. If the screen is not enough, the A640 is also equipped with an optical viewfinder standard, which allows to frame your photos to the old mode.

Its retractable screen aside, the A640 looks like a mid-size automatic rather ordinary. Measuring 4.3 cm thick with a weight of 340 g, it is too large to fit easily into a pocket. However, it is no evil box in a bag or jacket. The device works with four AA batteries that fits into the right handle, which gives it a slightly more rounded than most aircraft of this size. The controls consist of a wheel selection of modes, a control pad, a toggle button zoom and other standard buttons but combined ergonomic way. The various buttons and reagents are relatively easy to locate with the thumb, but one for shooting and reading is difficult to handle because of his flat.

The A640 is full of features that should please the most discerning photographers. In addition to the automatic modes and predefined scene, the camera offers the full range of modes P (scheduled), A (Aperture-priority), S (priority to the shutter speed) and M (manual), offering and the possibility of photographing a full manual mode. The A640 uses a 35-140 mm (equivalent to a 35 mm camera) without pretension, which gives capabilities zoom slightly higher than those devices standard 3x zoom. If the 4x zoom is not enough, remember that this camera accepts additional optics. On its website, Canon currently offers a converter focal wide-angle and a telephoto lens. The A640 has produced performance rather fast, only the burst mode a little disappointing just wear a dark side. After a time which starts at 1.5 seconds, the time between every shot was 1.7 seconds under a bright light and 2.4 seconds when the flash was activated. The time of the shutter (time lag between the moment you press the shutter and when the picture is taken) has been pleasantly short, ceiling to less than 0.5 seconds. Unfortunately, the burst mode of this 10-megapixel camera could not take just 44 shots in 34.5 seconds, representing a rate of only 1.3 scrolling image per second (fps). To be honest, it is likely that it takes the high resolution of the A640: it takes longer to deal with shots of 10 megapixels only 7 megapixels.

The sharpness of photos taken with a low ISO sensitivity is sufficient for prints well beyond size 20 x 25, but the camera tends to blur the bright areas. Noise begins to emerge from 200 ISO, but up to 400 ISO, it is limited to a regular grain and discreet. A 800 ISO, it exceeds the regular stage of grain and manifests itself in the form of speckles and bright spots. If we add to this the absence of noise image stabilizer, the A640 is not the best choice for shooting a burst or low-light conditions.

Apart from the problems encountered in these conditions, pictures of the A640 were sharp and detailed. We have noticed little effect fringe or distortion, and fine details emerge fairly clear, especially with the ISO sensitivity settings lowest. The colors seem generally eased a little and pale, but otherwise, the pictures are very beautiful.
