Canon 100D versus Canon Rebel

The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS Digital Rebel (labelled Canon 300D in some countries) are two digital cameras that were announced, respectively, in March 2013 and August 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 100D has a resolution of 17.9 megapixel, whereas the Rebel provides 6.3 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 100D vs Canon Rebel

An illustration of the physical size and weight of the Canon 100D and the Canon Rebel is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 100D – 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 Rebel is notably larger (32 percent) than the Canon 100D. Moreover, the Rebel is substantially heavier (59 percent) than the 100D. In this context, it is worth noting that neither the 100D 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 find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the Rebel can take 400 images on a single charge of its BP-511 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was launched at a markedly lower price (by 39 percent) than the Rebel, 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 100D vs Canon Rebel

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 3 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.

Canon 100D and Canon Rebel sensor measures

Despite having a slightly smaller sensor, the Canon 100D offers a higher resolution of 17.9 megapixel, compared with 6.3 MP of the Canon Rebel. 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 4.31μm versus 7.38μm for the Rebel). However, it should be noted that the 100D is much more recent (by 9 years and 7 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.

100D versus Rebel MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the 100D has a notably higher overall DXO score than the Rebel (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The 100D indeed provides movie recording capabilities, while the Rebel does not. The highest resolution format that the 100D can use is 1080/30p.

 

Feature comparison: Canon 100D vs Canon Rebel

Apart from body and sensor, cameras can and do differ across a range of features. The 100D 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 adjacent table lists some of the other core features of the Canon 100D and Canon Rebel along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the Rebel has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

Both the 100D and the Rebel have been discontinued, but can regularly be found used on eBay. The Rebel was replaced by the Canon XT, while the 100D was followed by the Canon 200D.

Review summary: Canon 100D vs Canon Rebel

So how do things add up? Is there a clear favorite between the Canon 100D and the Canon Rebel? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 100D:

  • More detail: Offers more megapixels (17.9 vs 6.3MP) with a 69% higher linear resolution.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (4.9 vs 2.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (117x91mm vs 142x99mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 242g or 37 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
  • More modern: Reflects 9 years and 7 months of technical progress since the Rebel launch.


Arguments in favor of the Canon EOS Digital Rebel:

  • 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 100D is the clear winner of the match-up (12 : 1 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.

100D 12:01 Rebel

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 100D or the Rebel. 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 hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
