Canon IXUS 140 Review

Image Quality


All of the sample images in this review were taken using the 16 megapixel Superfine JPEG setting, which gives an average image size of around 5Mb.

The Canon IXUS 140 produces images of above average quality. It recorded noise-free images at ISO 100-200, but trhere's already some noise and slight colour desaturation at ISO 400. ISO 800 shows more obvious noise and loss of colour but still remains perfectly usable, with the fastest speed of ISO 1600 worth avoiding if possible.

The Canon IXUS 140 handled chromatic aberrations fairly well, with some purple fringing effects appearing only in high contrast situations. The built-in flash worked well indoors, with just a hint of red-eye and good overall exposure, although there's noticeable vignetting at 28mm. The night photograph was excellent, with the maximum shutter speed of 15 seconds being long enough for most after-dark shots.

The image stabilisation system works well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. Macro performance is excellent, allowing you to focus as close as 1cm away from the subject. The images were a little soft straight out of the Canon IXUS 140 at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting.

Noise

There are 5 ISO settings available on the Canon IXUS 140. Here are some 100% crops which show the noise levels for each ISO setting.

ISO 100 (100% Crop)

ISO 200 (100% Crop)

   

ISO 400 (100% Crop)

ISO 800 (100% Crop)

   

ISO 1600 (100% Crop)

 
 

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level to suit your tastes via the My Colors menu option.

Chromatic Aberrations

The Canon IXUS 140 handled chromatic aberrations fairly well during the review, with some purple fringing present around the edges of objects in high-contrast situations, as shown in the examples below.

Macro

The Canon IXUS 140 offers a Macro setting that allows you to focus on a subject that is 1cm away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Canon IXUS 140 are Auto, Flash On, Slow Synchro, and Flash Off, with Red-eye Correction and Red-Eye Lamp settings available via the Flash Settings main menu option. These shots of a white coloured wall were taken at a distance of 1.5m.

Flash Off - Wide Angle (28mm)

Flash On - Wide Angle (28mm)

Flash Off - Telephoto (224mm)

And here are some portrait shots. Neither the Flash On or the Red-eye Correction settings could totally remove red-eye.

Night

The Canon IXUS 140's maximum shutter speed is 15 seconds in the Long Shutter mode, which is good news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 15 seconds at ISO 100. The camera takes the same amount of time again to apply noise reduction, so for example at the 5 second setting the actual exposure takes 10 seconds.

Anti Shake

The Canon IXUS 140 has an anti-shake mechanism, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, we took 2 handheld shots of the same subject with the same settings. The first shot was taken with anti shake turned off, the second with it turned on. Here are some 100% crops of the images to show the results. As you can see, with anti shake turned on, the images are much sharper than with anti shake turned off.
