Canon IXUS 150 Review

June 3, 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

There are 5 ISO settings available on the Canon IXUS 150. Here are some 100% crops which show the noise levels for each ISO setting.

The IXUS name is synonymous with good quality in all aspects. Therefore when we perform the tests, we expect to see a good performance. Still, it has to be remembered that this is a camera at around £100 so it's not going to be a top dog. However, we were still disappointed to see some speckles of noise showing at ISO 100. It needs bearing in mind that we're being hyper critical because we're noticing this only when viewed at full magnification. In fact, if you were to view the pictures at normal size on your computer, noise doesn't really show up until around ISO 800. Even then it's tolerable. The range of the IXUS 150 is ISO 100-1600 which is limited by today's standards.

Colour noise doesn't affect the image at full magnification until ISO 400 where some blobs of green are noticeable in the darker areas. At ISO 800, the colour noise increases as noise reduction fails to cope with the barrage and salt and pepper starts to make things awkward too. Sharp lines begin to break up and look fuzzy while details are smudging out.

Sharpening

It can be said that adding sharpening to the pictures taken on this camera is noticeable, but it's not necessarily the best course of action. We noticed that if you shoot over ISO 100 and there's any noise showing through, it simply gets made worse with sharpening. However, low ISO images certainly do benefit from a boost in sharpening.

Focal Range

The Canon IXUS 150's 8x zoom lens provides a focal length of 28-224mm in 35mm terms, as demonstrated below.

Chromatic Aberrations

One of the areas we're most disappointed in is the quality of the lens. We found chromatic aberration all over the place.

Macro

The close focusing of the IXUS 150 is 1cm. It can certainly come in very useful, although we found that image drop off comes in very early. There's only a small sweet spot in the centre of the frame. Focusing on small items is also quite difficult.

Flash

Adding flash to a picture will stabilise available light and because it's an intelligent flash, won't bleach out subjects unless they're far too close. There's some harsh vignetting at the wide-angle setting but this does dissipate as you move out to full zoom.

We did get some red-eye when taking portraits. Using the red-eye correction function does reduce it, but a correction system suggests it removes it. However, it does this digitally, so will be programmed to look for certain colours and it's quite possible that this was outside of the gamut.

Night

There are two modes that you can take pictures in low light. Program mode will allow exposures of up to 1sec, but if it can't cope with the amount of available light, then you can choose the Long exposure mode.

In Long exposure, you can select various shutter speeds up to 15sec. The great news is that the camera will select a low ISO of around 100 to increase image quality.
