Canon IXUS 275 HS Review

September 22, 2015 | Amy Davies | |

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 7Mb.

Directly from the Canon IXUS 275 HS, colours are bold and vibrant, and are basically typical of the warmth that Canon cameras are known for. If you want to alter the appearance of colours in your shot, you can do this via the MyColors setting, which is useful if you’re not getting quite the appearance you want - for instance, you might wish to boost the contrast of colours for flower shots, but keep them more neutral for general landscapes.

The overall impression of detail in shots taken with the Canon IXUS 275 HS is great when you’re viewing at normal printing or web sizes (such as A4 or below), but it’s possible to see image smoothing when you look closely at an image, even in low sensitivity shots, such as ISO 100. 

Looking at images taken at higher sensitivities, such as ISO 1600, it’s possible to see some loss of detail even when you’re viewing at A4 type sizes - but that’s pretty much to be expected from cameras like this. However, if you’re only sharing on Facebook and the like, you should be fine - and it’s certainly better to have a little loss of detail rather than a blurry shot.

In the majority of cases, the IXUS 275 HS’s general-purpose metering system does an excellent job of accurately measuring the scene to produce accurate exposures. If you need to add or reduce the brightness a little, you can adjust exposure compensation in Program mode. Similarly, automatic white balance produces generally accurate colours even when faced with artificial light - if you find that it’s producing slightly too warm tones, again, you can alter the white balance setting in Program mode.

Images taken at the far reach of the telephoto optic display a good level of detail. Although there’s a significant loss of detail when using the first of the digital zooms, it’s not too bad when viewing at small sizes. The second digital zoom is recommended only if you desperately want to get closer to the subject.

Noise

The Canon IXUS 275 HS has six sensitivity settings at full resolution. Auto mode uses a range between ISO 100 and ISO 3200, or you can switch to the Program shooting mode to manually select these settings.

Sharpening

We found that the Canon IXUS 275 HS images are already pretty sharp, but do benefit from a little touch up in post processing.

Focal Range

The Canon IXUS 275 HS' 12x zoom lens achieves a maximum wide-angle focal length equivalent to 25mm, and is capable of a telephoto reach of 300mm (in 35mm-camera terms).

Chromatic Aberrations

The Canon IXUS 275 HS handled chromatic aberrations fairly well during the review, with purple and green fringing present around the edges of objects in high-contrast situations, as shown in the examples below.

File Quality

Every image size option on the Canon IXUS 275 HS is accompanied by two quality settings: Fine and Super Fine. Going for the latter will up the file size of each image from 6MB to around 8MB.

SuperFine (8.22Mb) (100% Crop)

Fine (5.82Mb) (100% Crop)

Macro

The close focusing of the Canon IXUS 275 HS at wide-angle is a mere 1cm. It does mean that there's little light getting in when you do that and the edge definition drops off leaving around 50% of the image in focus.

Flash

The Canon IXUS 275 HS' flash can only manage a relatively weak 4m range and hence there's some fairly obvious vignetting in our wide-angle test shot taken at a distance of 1.5m. The flash has four modes: Auto, On, Off and Slow Synchro, plus a separate setting to enable or disable red-eye reduction. Whether this is active or not, the camera successfully avoids any trace of red-eye.

Flash Off - Wide Angle (24mm)

Flash On - Wide Angle (24mm)

Flash Off - Telephoto (300mm)

Flash On - Telephoto (300mm)

And here are some portrait shots.

Night

The Canon IXUS 275 HS's maximum shutter speed is 15 seconds, which is great news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 15 seconds at ISO 80.
