Canon G1 X Mark III versus Canon 80D

The Canon PowerShot G1 X Mark III and the Canon EOS 80D are two enthusiast cameras that were officially introduced, respectively, in October 2017 and February 2016. The G1X Mark III is a fixed lens compact, while the 80D is a DSLR. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G1 X Mark III and the Canon 80D. Three consecutive perspectives from the front, the top, and the back are presented. 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 – the G1X Mark III – represents the basis or 100 percent across all the size and weight measures).

Body view (G1X Mark III on the left)

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 80D is considerably larger (148 percent) than the Canon G1 X Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build in, whereas the 80D 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 80D 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 comparisons there.

The listed 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

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tent to 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 80D is 2 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (G1X Mark III) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G1 X Mark III and Canon 80D sensor measures
Sensor size

Even though the 80D has a slightly larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the 80D has a lower pixel density and marginally larger individual pixels (with a pixel pitch of 3.75μm versus 3.72μm for the G1X Mark III), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the G1X Mark III is a somewhat more recent model (by 1 year and 7 months) than the 80D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the 80D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon G1 X Mark III and Canon 80D along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the G1X Mark III and the 80D are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 80D replaced the earlier Canon 70D, while the G1X Mark III followed on from the Canon G1 X Mark II.

Summary

So what conclusions can be drawn? Is the Canon G1 X Mark III better than the Canon 80D or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon PowerShot G1 X Mark III:

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Faster burst: Shoots at higher frequency (9 vs 7 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a build-in lens, while the 80D requires a separate lens.
  • More compact: Is smaller (115x78mm vs 139x105mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the 80D).
  • More modern: Is somewhat more recent (announced 1 year and 7 months after the 80D).

Advantages of the Canon EOS 80D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (960 versus 200) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (6 points each). 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.

G1X Mark III 06:06 80D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G1X Mark III and the 80D 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
