Canon 100D vs G1X
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon PowerShot G1 X are two digital cameras that were announced, respectively, in March 2013 and January 2012. The 100D is a DSLR, while the G1X is a fixed lens compact. The cameras are based on an APS-C (100D) and an 1.5-inch (G1X) sensor. The 100D has a resolution of 17.9 megapixels, whereas the G1X provides 14.2 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 PowerShot G1 X? 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 G1 X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The 100D can be obtained in two different colors (black, white), while the G1X is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X is notably smaller (11 percent) than the Canon 100D. In this context, it is worth noting that neither the 100D nor the G1X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built 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 compare the optics available for the 100D and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.
(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.
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. 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.
The size of the imaging sensor is a crucial determinant 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 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 G1 X an 1.5-inch sensor. The sensor area in the G1X is 21 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.85. The sensor in the 100D has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.
With 17.9MP, the 100D offers a higher resolution than the G1X (14.2MP), but the 100D nevertheless has marginally larger individual pixels (pixel pitch of 4.31μm versus 4.30μm for the G1X) due to its larger sensor. Moreover, the 100D is a somewhat more recent model (by 1 year and 2 months) than the G1X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
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 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 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 PowerShot G1 X are ISO 100 to ISO 12800 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|Canon 7D II||APS-C||20.0||5472||3648||1080/60p||22.4||11.8||1082||70|
|Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|Panasonic G6||Four Thirds||15.9||4608||3456||1080/60p||21.3||11.5||639||61|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 100D provides a higher frame rate than the G1X. It can shoot video footage at 1080/30p, while the G1X is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The 100D and the G1X 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 100D, the Canon G1 X, and comparable cameras.
|Canon G1 X||optical||n||3.0||922||Swivel||n||1/4000s||1.9||Y||Y|
|Canon 7D II||optical||Y||3.0||1040||fixed||n||1/8000s||10.0||Y||n|
|Canon G1 X Mark II||optional||n||3.0||1040||tilting||Y||1/4000s||5.2||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 100D does not have a selfie-screen.
Concerning the storage of imaging data, both the 100D and the G1X write their files to SDXC cards. The 100D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1X cannot take advantage of Ultra High Speed SD 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 PowerShot G1 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D has a microphone port, which is missing on the G1X. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the 100D and the G1X have been discontinued, but can regularly be found used on eBay. The G1X was replaced by the Canon G1X Mark II, 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? Which of the two cameras – the Canon 100D or the Canon G1 X – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 14.2MP) with a 15% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k 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 1.9 flaps/sec) to capture the decisive moment.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (380 versus 250) on a single battery charge.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Is somewhat more recent (announced 1 year and 2 months after the G1X).
Reasons to prefer the Canon PowerShot G1 X:
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Ready to shoot: Comes with an integrated lens, while the 100D requires a separate lens.
- More compact: Is smaller (117x81mm vs 117x91mm) and will fit more readily into a bag.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More heavily discounted: Has been on the market for longer (launched in January 2012).
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 : 5 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 100D and the Canon G1 X place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings 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 incomplete and does no justice, for example, to the way the 100D or the G1X perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
