Canon A3100 IS - New cheap model for family

Give up lumpish figure of line A, the line PowerShot A3100 IS  close to IXUS  fashion than by using compact lithium.


PowerShot A3100 IS is a version cheap for travel to basic parameters of 12.1 million pixel sensor, image processor DIGIC III, anti-vibration lens with 4x optical zoom and 2.7 inch LCD screen . Release replaces the A1100 IS, we can say this is the first line A has strongly retired from the AA batteries instead of lithium as other tourist lines. Larger screen by previous optical sight bracket should be removed also. Card slot is updated with the ability to support high capacity SDXC cards up to 32GB .

Same batch released this innovative line of A can also always the computer, including the A3000 IS, because the two virtually identical all parameters, except the A3000 IS has a lower resolution, only 10 million pixels.

Do not use the battery should state in the shape of A3100 IS looks more compact, although the actual size and weight is similar. Left hand to the collapse than the A1100 IS does not make sense not so sure. The button layout is quite reasonable for your situation and adjust with one hand easily.

However roundabout in Edit mode on very hard, so to switch modes are best held hands. Although a bit inconvenient but designed to avoid this roundabout prone to move suddenly during influenza machine.

Although imaging button and power switch placed next to each other by design, but should work reasonably hard to press the wrong place. Zoom button instead of resolve in to button press the back , quite similar to the compact version of the Canon recently but may be more inconvenient for some people familiar with the mechanism dupe tradition.

The back button is also a little easier thanks to the removal button to print directly, perhaps because the period studied the market, Canon see some people do not use this feature. But to get familiar, the airline has arranged this feature built-in navigation buttons adjust the mode on the back.

Basically, the mode control is quite familiar with the Func Set button in the center of the ring to navigate, allowing access and change the parameters of film sensitivity, white balance, color correction, brightness, sequence or resize images ... Also helped the navigation buttons for quick access to exposure compensation parameters, lights, automatic capture and macro mode.

Compact flash to capture the far left corner for up to 4 meters. Through the transition to using lithium-time feedback so light has improved significantly with the slow speed of the line before are using AA batteries (sometimes to 7 seconds). Recovery time of the A3100 IS are located within about 3 seconds, longer if you switch to continuous shooting, the shooting can maintain lights at speeds of about 2 seconds / image.

However, switching to compact lithium line also revealed only one clear advantage in the recovery time lights, also other functions also do not have outstanding compared to previous versions. Duration of the battery is only about 240 types / times for charging, less than the predecessor, the A1100 IS and the same time the A490 IS and A495 IS.







PowerShot A3100 IS is equipped with a 4x optical zoom, equivalent to 35 - 140mm with aperture f / 2.7 to 5.5 anti-vibration mechanism and tradition of Canon optics. When boot lens out of about 24mm. Startup time which is about 2 seconds, not too fast but enough for most cases. Zoom is divided into seven levels with time from wide angle to full telephoto takes about 1.5 seconds.

The auto mode of the Canon works pretty perfect, especially the mechanism automatically Face Face Detection AiAF with very high adhesion ability. Although still limited in speed of identification in low light, but if more than faces (for example: taken collectively), the weakness also easily be overcome.

LCD screen on the A3100 IS in comparison with standard cameras now popular with 2.7 inch width and resolution of 230,000 pixels. Was eliminated by optical frame should watch this screen will play a vital role in taking photos of this model, so the screen is designed display good at all angles although still quite limited under sunlight directly.

Designed towards the user should simply preferred modes of automation A3100 IS up instead support the main features hand. Only the capture mode Program can intervene to parameters such as ISO, also the parameters of exposure will make the whole machine. Support the mechanism of this intelligent system automatically receive default Intelligent Auto scene.

In order to reduce the price to suit the average user of the object, although the new version is released but was able to remove HD video mode, instead of recording VGA standard mode 640 x 480 pixels at a rate of 30 frames per second. Compressed MPEG movies and save the common AVI format. Recording time is not limited to the full optical zoom and memory card is blocked when the film is activated, instead of using only the digital zoom.


Time sequence of versions A3100 IS in fact better than the specifications with the speed of 0.9 frames per second resolution and highest image quality (parameter of 0.8 frames / second). Unlike the mechanism of sequence of other manufacturers are likely to increase as lower-resolution version A3100 IS kept relatively stable rate in most resolutions. The continuous shooting mode in low light conditions (Low Light Mode), speeding up the camera a bit to 2.6 frames per second at a resolution of 2 million pixels.

On A3100 IS ISO range 80-1600, but no mode click on 3200 as a version number of this company. Shutter speed extends from 1 to 1 / 1500 sec and can last up to 15 seconds (in some modes).

When comparing the actual shooting at low ISO with two versions of the same level PowerShot A490/A495 and the Nikon Coolpix l22, A3100 IS results do not matter but not in the version now travel by Canon (the A490 is a typical example). In return, the colors shown in the panoramic scene and has been showing good crop though not sufficient clearness. With high ISO and light conditions indoors and one lens was extended, the quality of the A3100 IS can be improved even more still "below the" A490. At ISO 200 the quality, nothing censurable the noise under control quite well. ISO 400 noise starts to increase markedly over the color display is quite stable. From ISO 800 to 1600 particles is much noise and should be permanently taken in cases of real need.

A current version is the first to use lithium batteries instead of AA tradition, Canon PowerShot A3100 IS close to the IXUS line with the big screen and compact body. Unfortunately, the new battery also improve feedback speed of light, also is not revealing the premium features including Vietnam, especially when calculating the duration. Although the lens is not wide enough but also a range of government is quite reasonable and integrate the anti shake. As CameraLab, A3100 IS's image quality is even less than the same time, the A490 can say is too good compared to other competitors in the market, especially at the price announced only 180 USD.
