Canon 300D versus Canon 30D

The Canon EOS 300D (called Canon Rebel in some regions) and the Canon EOS 30D are two digital cameras that were announced, respectively, in August 2003 and February 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 300D has a resolution of 6.3 megapixel, whereas the 30D provides 8.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 300D vs Canon 30D

The side-by-side display below illustrates the physical size and weight of the Canon 300D and the Canon 30D. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 300D – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 30D is notably larger (9 percent) than the Canon 300D. Moreover, the 30D is markedly heavier (21 percent) than the 300D. In this context, it is worth noting that neither the 300D nor the 30D are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 300D gets 400 shots out of its BP-511 battery, while the 30D can take 750 images on a single charge of its BP-511A power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 300D was launched at a markedly lower price (by 36 percent) than the 30D, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison: Canon 300D vs Canon 30D

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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 30D is 1 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 300D and Canon 30D sensor measures

Despite having a slightly smaller sensor, the 30D offers a higher resolution of 8.2 megapixel, compared with 6.3 MP of the 300D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.42μm versus 7.38μm for the 300D). However, it should be noted that the 30D is much more recent (by 2 years and 6 months) than the 300D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

300D versus 30D MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the 30D has a markedly higher DXO score than the 300D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, and 0.4 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Neither the 300D nor the 30D offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison: Canon 300D vs Canon 30D

Apart from body and sensor, cameras can and do differ across a range of features. The 300D and the 30D 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 table below summarizes some of the other core capabilities of the Canon 300D and Canon 30D in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Canon 300D vs Canon 30D

So how do things add up? Is the Canon 300D better than the Canon 30D or vice versa? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 300D:

  • Less heavy: Is lighter (by 136g or 17 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2003).

Reasons to prefer the Canon EOS 30D:

  • More detail: Has more megapixels (8.2 vs 6.3MP), which boosts linear resolution by 14%.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 2.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (750 versus 400) out of a single battery charge.
  • More modern: Reflects 2 years and 6 months of technical progress since the 300D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 30D is the clear winner of the contest (10 : 3 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.

300D 03:10 30D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 300D and the 30D in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
