Canon IXUS 145 Review

July 31, 2014 | Matt Grayson | |

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.

Noise

The ISO range on the IXUS 145 is fairly limited from ISO 100-1600. Noise performance at low sensitivity is very good. ISO 100 shows no discernible noise in shadows areas. There's plenty of detail and edge sharpness is great.

Looking at the pictures at full magnification, noise does start to show through at ISO 200, but this can't be seen at normal viewing distance. In fact you can't really see noise at normal distances until around ISO 800 which is pretty good. By that stage, noise control is really suffering. Detail has been lost as noise is blurred to keep it out. However, blobs of green still remain in shadow areas.

Sharpening

The IXUS 145 does provide very sharp pictures. However, we did also discover that adding some basic sharpening in an editing suite certainly improved the overall sharpness of the picture.

Focal Range

The Canon IXUS 145 has an 8x optical zoom. The range starts at 28mm which means it stretches up to 224mm in 35mm terms.

Chromatic Aberrations

One area that the IXUS 145 suffers badly in is chromatic aberration. It occurs when not all colours focus on the sensor and appear as thin lines on sharp edges. They usually manifest as purple lines on contrasting colours. It happens usually towards the far edges of the frame where the image quality isn't as sharp, but on the 145, we found evidence in the centre.

Macro

Close focusing on the IXUS 145 is 1cm. That's great for a small digital compact camera such as this. Be aware when using this mode because there's a steep image quality drop off from the centre spot.

Flash

The flash on the Canon IXUS 145 has a range of 50cm – 3m at wide-angle and 1.3-1.5m at full zoom. At the widest setting, the lens does pick up some vignetting but this disappears once the camera is zoomed in.

Red-eye reduction does appear using the IXUS 145. We switched on the red-eye reduction feature in the Main menu and it does reduce.  It's important to remember that this is a red-eye reduction, not red-eye removal.

Night

For the majority of night or low light shots, the Program mode should cope with the majority of situations. Program will expose up to a maximum of 1sec, so if you find yourself in a situation where you need a longer exposure, you can switch to the IXUS 145's Night mode which is actually called Long exposure. It's pretty cool, because it allows you to determine the length of the shutter speed to a maximum of 15seconds. It means that it's not just limited to night shots, but you can also do star trails or car light streaks, for example. The Long exposure mode also uses a low ISO because it's apparent that you'll be steadying the camera to prevent blurring.
