Canon 30D vs Rebel
The Canon EOS 30D and the Canon EOS Digital Rebel (labelled Canon 300D in some countries) are two digital cameras that were officially introduced, respectively, in February 2006 and August 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 30D has a resolution of 8.2 megapixels, whereas the Rebel provides 6.3 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 30D and the Canon EOS Digital Rebel? 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.
The physical size and weight of the Canon 30D and the Canon Rebel are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon Rebel is notably smaller (8 percent) than the Canon 30D. Moreover, the Rebel is markedly lighter (17 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the Rebel 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 compare the optics available in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Rebel was launched at a markedly lower price (by 36 percent) than the 30D, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 Rebel is 1 percent bigger. 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a slightly smaller sensor, the Canon 30D offers a higher resolution of 8.2 megapixels, compared with 6.3 MP of the Canon Rebel. 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 6.42μm versus 7.38μm for the Rebel). However, it should be noted that the 30D is much more recent (by 2 years and 6 months) than the Rebel, 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 30D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 30D for good quality output (200 dots per inch) amounts to 17.5 x 11.7 inches or 44.5 x 29.7 cm, for very good quality (250 dpi) 14 x 9.3 inches or 35.6 x 23.7 cm, and for excellent quality (300 dpi) 11.7 x 7.8 inches or 29.7 x 19.8 cm. The corresponding values for the Canon Rebel 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 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS Digital Rebel are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 30D has a notably higher overall DXO score than the Rebel (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, and 0.4 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.
Apart from body and sensor, cameras can and do differ across a variety of features. The 30D and the Rebel 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 30D has a higher magnification than the one of the Rebel (0.56x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 30D and Canon Rebel in connection with corresponding information for a sample of similar cameras.
One feature that is present on the 30D, but is missing on the Rebel is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
Concerning the storage of imaging data, both the 30D and the Rebel write their files to Compact Flash cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 30D and Canon EOS Digital Rebel and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the Rebel) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 30D and the Rebel have been discontinued, but can regularly be found used on eBay. The Rebel was replaced by the Canon XT, while the 30D was followed by the Canon 40D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon 30D or the Canon Rebel – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 30D:
- More detail: Offers more megapixels (8.2 vs 6.3MP) with a 14% higher linear resolution.
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.55x).
- Easier setting verification: Features an LCD display on top to control 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 (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 2.5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 400) on a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More modern: Reflects 2 years and 6 months of technical progress since the Rebel launch.
Advantages of the Canon EOS Digital Rebel:
- Less heavy: Has a lower weight (by 136g or 17 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2003).
If the count of relative strengths (bullet points above) is taken as a measure, the 30D is the clear winner of the match-up (13 : 3 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 30D and the Canon Rebel place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 says little about, for example, the shooting experience and imaging performance of the 30D and the Rebel 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 provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
