Canon PowerShot SD 4000 IS/IXUS 300 HS Review

August 2010 | By Richard Butler

The SD/IXUS range is made up of Canon's 'style-orientated' compact cameras and, as the rest of the market has fragmented into innumerable niches, the range has grown to accommodate an increasing variety of needs. The SD4000 IS tops the current lineup, offering a 3.8x wide-angle zoom and (despite its underlying point-and-shoot disposition) aperture and shutter priority modes. In addition the SD4000 IS is the first of its family to be based around a back-lit CMOS sensor that enables several high speed modes and promises improved low-light performance.

The SD4000 IS's low-key styling belies the fact that it's actually a very well-specified compact camera. In addition to the relative novelty of a back-lit CMOS sensor, it also features a lens that starts at a 28mm equivalent F2.0 - impressive even if it ends up at a rather less noteworthy F5.3 at the 105mm equivalent end of its zoom range. We're curious to see the effect of using a back-side illuminated CMOS sensor in the SD4000 IS, because in our experience the promises made for the low-light capability of these sensors (which gather light from what would be the back of a conventional CMOS design and thus remove all the support circuitry from the light path), are not always obvious compared to some of the most modern CCD designs.

However, the SD4000 IS does capitalize on the CMOS sensor's faster readout compared to CCD, using it to offer 720p HD video, 3.7fps full resolution continuous shooting, 8.4fps reduced resolution images and even 240fps movies which are played back at 30fps to give a slow-motion effect. Being the top of Canon's style compact range, the SD4000 IS also has a selection of extra shooting modes such as fisheye and miniature (mock tilt/shift) modes.

Conclusion / Recommendation / Ratings are based on the opinion of the reviewer, you should read the ENTIRE review before coming to your own conclusions.

Images which can be viewed at a larger size have a small magnifying glass icon in the bottom right corner of the image, clicking on the image will display a larger (typically VGA) image in a new window.

DPReview calibrate their monitors using Color Vision OptiCal at the (fairly well accepted) PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the (computer generated) grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally A,B and C.
