Canon 100D vs 300D
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 300D (labelled Canon Rebel 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 megapixels, whereas the 300D 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 100D and the Canon EOS 300D? 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.
An illustration of the physical size and weight of the Canon 100D and the Canon 300D 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.
The 100D can be obtained in two different colors (black, white), while the 300D is only available in silver.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 300D is notably larger (32 percent) than the Canon 100D. Moreover, the 300D is substantially heavier (59 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the 300D 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.

Any camera decision will obviously take relative prices into account. 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 300D, 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.
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 300D 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.
In terms of chip-set technology, the 100D uses a more advanced image processing engine (DIGIC 5) than the 300D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Canon 100D offers a higher resolution of 17.9 megapixels, compared with 6.3 MP of the Canon 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 4.31μm versus 7.38μm for the 300D). However, it should be noted that the 100D is much more recent (by 9 years and 7 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.
The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 300D are 15.4 x 10.2 inch or 39 x 26 cm for good quality, 12.3 x 8.2 inch or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inch or 26 x 17.3 cm for excellent quality prints.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 300D are ISO 100 to ISO 1600 (no boost).
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 300D (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 300D does not. The highest resolution format that the 100D can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 100D and the 300D 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 300D has a higher magnification than the one of the 100D (0.55x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 100D and Canon 300D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the 300D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The 100D writes its imaging data to SDXC cards, while the 300D uses 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 100D and Canon EOS 300D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the 300D have been discontinued, but can regularly be found used on eBay. The 300D was replaced by the Canon 350D, while the 100D was followed by the Canon 200D. 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 how do things add up? Is there a clear favorite between the Canon 100D and the Canon 300D? Which camera is better? 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).
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- 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.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- 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 300D launch.
Arguments in favor of the Canon EOS 300D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.54x).
- 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 (15 : 2 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 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.
How about other alternatives? Do the specifications of the Canon 100D and the Canon 300D 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D or the 300D. 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 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring 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.
