Canon 100D versus Canon G9 X

The Canon EOS 100D (called Canon SL1 in some regions) and the Canon PowerShot G9 X are two digital cameras that were officially introduced, respectively, in March 2013 and October 2015. The 100D is a DSLR, while the G9X is a fixed lens compact. The cameras are based on an APS-C (100D) and an one-inch (G9X) sensor. The 100D has a resolution of 17.9 megapixel, whereas the G9X provides 20 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 G9 X

An illustration of the physical size and weight of the Canon 100D and the Canon G9 X is provided 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. 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 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 G9 X is considerably smaller (47 percent) than the Canon 100D. In this context, it is worth noting that neither the 100D nor the G9X are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens build in, whereas the 100D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 100D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the G9X can take 220 images on a single charge of its NB-13L power pack.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G9X was launched at a lower price than the 100D, despite having a lens build in. 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 100D vs Canon G9 X

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 100D and Canon G9 X sensor measures

Despite having a smaller sensor, the G9X offers a higher resolution of 20 megapixel, compared with 17.9 MP of the 100D. 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 2.41μm versus 4.31μm for the 100D). However, it should be noted that the G9X is much more recent (by 2 years and 6 months) than the 100D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

100D versus G9X MP

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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60p, while the 100D is limited to 1080/30p.

 

Feature comparison: Canon 100D vs Canon G9 X

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon 100D, the Canon G9 X, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Canon 100D vs Canon G9 X

So what conclusions can be drawn? Which of the two cameras – the Canon 100D or the Canon G9 X – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 100D:

  • Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (380 versus 220) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in March 2013).


Reasons to prefer the Canon PowerShot G9 X:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Faster burst: Shoots at higher frequency (6 vs 4.9 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 100D requires a separate lens.
  • More compact: Is smaller (98x58mm vs 117x91mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 100D).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 2 years and 6 months of technical progress since the 100D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the G9X is the clear winner of the contest (10 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

100D 06:10 G9X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the G9X handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
