Canon 300D vs G12

The Canon EOS 300D (called Canon Rebel in some regions) and the Canon PowerShot G12 are two digital cameras that were revealed to the public, respectively, in August 2003 and September 2010. The 300D is a DSLR, while the G12 is a fixed lens compact. The cameras are based on an APS-C (300D) and a 1/1.7-inch (G12) sensor. The 300D has a resolution of 6.3 megapixels, whereas the G12 provides 10 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 300D and the Canon PowerShot G12? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Canon 300D and the Canon G12 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

Compare 300D versus G12 top
Comparison 300D or G12 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G12 is considerably smaller (39 percent) than the Canon 300D. In this context, it is worth noting that neither the 300D nor the G12 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 has a lens built in, whereas the 300D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 300D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 300D gets 400 shots out of its BP-511 battery, while the G12 can take 370 images on a single charge of its NB-7L power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G12 was launched at a lower price than the 300D, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 300D features an APS-C sensor and the Canon G12 a 1/1.7-inch sensor. The sensor area in the G12 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.6. The sensor in the 300D has a native 3:2 aspect ratio, while the one in the G12 offers a 4:3 aspect.

Technology-wise, the G12 uses a more advanced image processing engine (DIGIC 4) than the 300D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 300D and Canon G12 sensor measures

Despite having a smaller sensor, the G12 offers a higher resolution of 10 megapixels, compared with 6.3 MP of the 300D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.07μm versus 7.38μm for the 300D). However, it should be noted that the G12 is much more recent (by 7 years) than the 300D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G12 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G12 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inches or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inches or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inches or 30.9 x 23.2 cm. The corresponding values for the Canon 300D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.

The Canon EOS 300D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

300D versus G12 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 300D has a notably higher overall DXO score than the G12 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.4 EV of lower dynamic range, and 1.8 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G12 indeed provides for movie recording, while the 300D does not. The highest resolution format that the G12 can use is 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 300D and the G12 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The adjacent table lists some of the other core features of the Canon 300D and Canon G12 along with similar information for a selection of comparators.

Both the 300D and the G12 have been discontinued, but can regularly be found used on eBay. The 300D was replaced by the Canon 350D, while the G12 was followed by the Canon G15. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what is the bottom line? Is the Canon 300D better than the Canon G12 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 300D:

  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (1.8 stops ISO advantage).
  • Faster burst: Shoots at higher frequency (2.5 vs 1.1 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • More heavily discounted: Has been available for much longer (launched in August 2003).


Advantages of the Canon PowerShot G12:

  • More detail: Has more megapixels (10 vs 6.3MP), which boosts linear resolution by 24%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC).
  • Broader imaging potential: Can capture not only stills but also 720/24p video.
  • Larger screen: Has a bigger rear LCD (2.8" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (461k vs 118k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Ready to shoot: Comes with an integrated lens, while the 300D requires a separate lens.
  • More compact: Is smaller (112x76mm vs 142x99mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 300D).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 7 years of technical progress since the 300D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G12 is the clear winner of the contest (13 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

300D 05:13 G12

How about other alternatives? Do the specifications of the Canon 300D and the Canon G12 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 300D or the G12 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
