Canon IXUS 115 HS - Test shots: ISO performance

By Gavin Stoker



Our Score:


A selection of images taken at the camera's incremental light sensitivity settings, using only available daylight. The IXUS 115 HS ISO range just like that of the 220 HS is modest and straightforward, starting out at ISO100 and working its way up to ISO3200, though Canon does throw in an additional Low Light shooting mode for fully auto snapping, the caveat being a resolution drop to three megapixels. Let's see how well the Canon copes...



With the camera's Auto ISO setting aptly choosing the lowest manually selectable option of ISO100, the shot is amazingly clear and crisp for a budget snapper and there's no noise to report in shadow areas.


Same lack of noise to report at ISO200 thanks to a nigh identical result.


We're at ISO400, usually the setting at which noise begins to creep in on cheaper compacts. While we're not seeing noise, the shot is ever so slightly softer than the preceding two settings.


The same test subject at ISO800, and overall the image is still fairly clean if we're slightly losing edge definition on close inspection.


Slightly softer again when it comes to detail examining our test image under close scrutiny at ISO1600. But again most would be hard pressed to spot any deterioration when viewing the full frame.


A marginally grittier and the same time softer image at ISO3200 but not a pronounced jump in terms of degradation over ISO1600. Overall the Canon 115 HS has performed very respectably in this task, giving a near identical showing to the slightly more expensive 220 HS and 310 HS siblings.


...And so we've tried shooting our test image with Low Light mode selected, which effects an image drop to three megapixels. Here the camera has itself chosen a setting which equates to ISO400, so again, no apparent noise, but we are getting a pixellated effect when cropping in to the same degree as the shots above.

I bought one of these 2 weeks ago, and I am probably going to send it back. The Backlit CMOS sensor gives great low light performance, but in good light it gives worse pictures than my old CCD equipped IXUS 90 IS.
The focus is also slower, and it often fails to focus correctly. If you are going to shoot mainly in good light it it worth bearing this is mind.

Bought this two days ago. Have gone through all operational techniques.A nice handy camera with very good low light performance (considering the sensor size for this type). Image quality is quite good; so is its video recording capability. Cons:1. very scantily spaced control buttons; 2.cannot enter into digital (not optical) zoom for still images and video recording unless aspect ratio is set to 4:3, although the camera has shooting options in other desired aspect ratios.

Been playing with this camera for a couple of weeks. Mixed results. It's behaved well in a variety of conditions and I love that I can fit a camera of this quality in a trouser pocket. On the other hand, I'm really annoyed that pictures taken with digital zoom are enlarged to the currently selected resolution.

Update! Have you thought about - TOST ZON DISCOUNTS (should be on google have a look)? Ive heard some unbelievable things about it and my auntie saved tons of money with it.
