Canon IXUS 300 HS - Test Shots - ISO Performance

By Cliff Smith



Our Score:


Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using shaded natural light.

This is the full frame at the minimum of 125 ISO.

At 125 ISO the image quality is virtually flawless.

Still no problems at 200 ISO.


Canon IXUS 300 HS test photo

Almost noise free at 400 ISO.


Canon IXUS 300 HS test photo

Noise reduction has blurred some detail at 800 ISO, but image quality is still very good.


Canon IXUS 300 HS test photo

Slightly less detail at 1600 ISO, but still very little noise.

Even at 3200 ISO the image is still printable.

Isn't this camera basically the S90 without the ability to shoot RAW?

The very excellent (I bought one!) Panasonic TZ7 can now be had for under £200 which has to be a stonking bargain for a camera which would probably equal or better this one for image quality.

How does the reader interpret the image quality score of 9 for 300 HS vs for thirds vs dslr aps sensor equipped products? Would be useful, in my opinion, to get a relative image score (against other compacts in its class) & also an absolute image quality score.

For example, does the Canon EOS 550D and Canon IXUS 300 HS (both score 9) have identical image quality if you review the output without regard for the device?

The image quality score interpretation will become even more confusing as future cameras do not fit comfortably into the existing categories, e.g. Sony NEX-5.

GerryD: IMO it would be impossible to have an "absolute" score for image quality; it can only be relative. For example if you were to use digital medium format cameras costing many thousands of pounds as the standard, then even the highest-end full-frame dSLRs would end up with a relatively average IQ score - which would hardly be fair.

Your review makes for interesting reading. I was looking forward to this review with anticipation, especially as it's the 1st compact Canon have used a CMOS sensor in so was expecting good things. I was disappointed to read the auto focus feature on this model as being 'sluggish' in low light conditions, as this is partly what this model was hailed as by Canon.AlsoI feel ( probably as will most member of the public who are interested in purchasing a compact), that the price this has debued at is just too high to be competative at present.I also feel Canon could have made the zoom more versatile, i.e. zooming in more than 3.8x, the wide angle bit is probably about right to avoid barrel distortion. Maybe they'll introduce a DIGIC 5 processor?!to speed opeartion up. I think these are my main bones of contention and until Canon improve on the overall perfromance of this camera, my money stays where it is! Come on Canon, i want to buy an IXUS with CMOS sensor as they're good, but just no way at this price for that tech spec!

"Isn't this camera basically the S90 without the ability to shoot RAW?"

While I can see why you might think that, it's not. The manual controls aren't as extensive or as accessible as on the S90 and this has HD video as well as a host of other modes made for the ixus user over more technical users. The sensors are also different, this is CMOS (like in SLRs), the S90 is a special CCD made for low light scenarios. Basically - this is for everyone (all be it a rich everyone), the S90 is more prosumer in my opinion.

Having used this out and about, it's stonking at low-light shots.

I've got an S90 and was very interested to see how the CMOS would work out in comparison and it does a great job. Easily one of the best low-light performers I've seen. Yes, it's expensive, but Canon always put a crazy entry price then slash it after not long at all.

I didn't get any lag with focus to be honest though did most of my shooting in a restaurant, so my tests weren't rigorous. It was just great having a pocketable, reasonable megapixeled camera that handles low-light and has stereo HD video. I really liked the size as well - MUCH more pocketable than my S90.

Oh, and having had a TZ7 before - yes, £200 is a good price for it, but this delivers MONUMENTALLY better low-light performance and I found it quite a bit zippier too.

I have had this a month now and found it a excellent point and shoot with just enough to temp you into photography. I think it is awesome for the size. Lacks in the optical Zoom but has everything else, good low light performance and HS means exactly that it is fast. I have never been so excited after buying a product as i have this. I am now looking at photography totally in a differnet way. and have started playing with all the settings. Never been bothered before. This has made me want to get a Super-Zoom camera or even a beginners DSLR. :)
