Canon 100D versus Canon G1 X Mark II

The Canon EOS 100D (called Canon SL1 in some regions) and the Canon PowerShot G1 X Mark II are two digital cameras that were officially introduced, respectively, in March 2013 and February 2014. The 100D is a DSLR, while the G1X Mark II is a fixed lens compact. The cameras are based on an APS-C (100D) and an 1.5-inch (G1X Mark II) sensor. The 100D has a resolution of 17.9 megapixel, whereas the G1X Mark II provides 13 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 G1 X Mark II

The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon G1 X Mark II. 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 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 G1 X Mark II is notably smaller (19 percent) than the Canon 100D. In this context, it is worth noting that neither the 100D nor the G1X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II 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 G1X Mark II can take 240 images on a single charge of its NB-12L power pack.

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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 G1 X Mark II

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Canon G1 X Mark II an 1.5-inch sensor. The sensor area in the G1X Mark II 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 Mark II offers a 4:3 aspect.

Canon 100D and Canon G1 X Mark II sensor measures

With 17.9MP, the 100D offers a higher resolution than the G1X Mark II (13MP), but the 100D has smaller individual pixels (pixel pitch of 4.31μm versus 4.49μm for the G1X Mark II). Moreover, the G1X Mark II is a somewhat more recent model (by 10 months) than the 100D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

100D versus G1X Mark II MP

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"). Of the two cameras under review, the 100D has a notably higher overall DXO score than the G1X Mark II (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.5 EV in additional dynamic range, and 0.5 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).

 

Feature comparison: Canon 100D vs Canon G1 X Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G1X Mark II 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 G1 X Mark II, and comparable cameras.

The G1X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 100D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 100D was succeeded by the Canon 200D.

Review summary: Canon 100D vs Canon G1 X Mark II

So how do things add up? Is the Canon 100D better than the Canon G1 X Mark II or vice versa? 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 13MP) with a 20% higher linear resolution.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (380 versus 240) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in March 2013).


Reasons to prefer the Canon PowerShot G1 X Mark II:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Ready to shoot: Comes with an integrated lens, while the 100D requires a separate lens.
  • More compact: Is smaller (116x74mm vs 117x91mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (10 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 100D emerges as the winner of the contest (7 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

100D 07:05 G1X Mark II

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 G1X Mark II. 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 hands-on reviews by experts are important.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
