Canon 300D vs 100D

The Canon EOS 300D (called Canon Rebel in some regions) and the Canon EOS 100D (labelled Canon SL1 in some countries) are two digital cameras that were officially introduced, respectively, in August 2003 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 300D has a resolution of 6.3 megapixels, whereas the 100D provides 17.9 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 300D vs 100D

The side-by-side display below illustrates the physical size and weight of the Canon 300D and the Canon 100D. 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 dimensions 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 100D is notably smaller (24 percent) than the Canon 300D. Moreover, the 100D is substantially lighter (37 percent) than the 300D. In this context, it is worth noting that neither the 300D nor the 100D 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.

Concerning battery life, the 300D gets 400 shots out of its BP-511 battery, while the 100D can take 380 images on a single charge of its LP-E12 power pack.

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

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.

 

Sensor comparison: Canon 300D vs 100D

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. 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 100D is 3 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.

Technology-wise, 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.

Canon 300D and Canon 100D sensor measures

Despite having a slightly smaller sensor, the 100D offers a higher resolution of 17.9 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 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 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS 300D has a native sensitivity range from ISO 100 to ISO 1600 The corresponding ISO settings for the Canon EOS 100D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..

300D versus 100D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 100D has a markedly higher DXO score than the 300D (overall score 8 points higher), which will translate into better image quality. The 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 are not only capable of taking still images, but can also record movies. The 100D indeed provides for movie recording, while the 300D does not. The highest resolution format that the 100D can use is 1080/30p.

 

Feature comparison: Canon 300D vs 100D

Apart from body and sensor, cameras can and do differ across a variety of features. The 300D and the 100D 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 following table reports on some other key feature differences and similarities of the Canon 300D, the Canon 100D, and comparable cameras.

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 300D writes its imaging data to Compact Flash cards, while the 100D uses SDXC cards.

Review summary: Canon 300D vs 100D

So how do things add up? Which of the two cameras – the Canon 300D or the Canon 100D – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 300D:

  • More heavily discounted: Has been available for much longer (launched in August 2003).


Arguments in favor of the Canon EOS 100D:

  • More detail: Has more megapixels (17.9 vs 6.3MP), which boosts linear resolution by 69%.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie 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: Has a touchscreen to facilitate handling and shooting adjustments.
  • 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 will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 242g or 37 percent) and is thus easier to take along.
  • 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.

If the count of individual advantages (bullet points above) is taken as a guide, the 100D is the clear winner of the contest (15 : 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.

300D 01:15 100D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 300D and the 100D in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
