Canon 800D versus Canon G1 X Mark III

The Canon EOS 800D (called Canon T7i in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were revealed to the public, respectively, in February 2017 and October 2017. The 800D is a DSLR, while the G1X Mark III is a fixed lens compact. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel. 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 800D vs Canon G1 X Mark III

The physical size and weight of the Canon 800D and the Canon G1 X Mark III are illustrated 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. 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 – the 800D – represents the basis or 100 percent 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 III is considerably smaller (32 percent) than the Canon 800D. It is noteworthy in this context that the G1X Mark III is splash and dust-proof, while the 800D does not feature any corresponding weather-sealing.

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 800D 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 800D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 800D gets 600 shots out of its LP-E17 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 800D vs Canon G1 X Mark III

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 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 800D and Canon G1 X Mark III sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixel. This similarity in sensor specs implies that both the 800D and the G1X Mark III have the same pixel density, as well as the same pixel size. It should, however, be noted that the G1X Mark III is a somewhat more recent model (by 7 months) than the 800D, and its sensor might have benefitted from technological advances during this time.

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 (1080/60p).

 

Feature comparison: Canon 800D vs Canon G1 X Mark III

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the 800D 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 table below summarizes some of the other core capabilities of the Canon 800D and Canon G1 X Mark III in connection with corresponding information for a sample of similar cameras.

Review summary: Canon 800D vs Canon G1 X Mark III

So what conclusions can be drawn? Is the Canon 800D better than the Canon G1 X Mark III or vice versa? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 800D:

  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • 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 (600 versus 200) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2017).


Advantages 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 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 800D requires a separate lens.
  • More compact: Is smaller (115x78mm vs 131x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 800D).
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III emerges as the winner of the match-up (8 : 6 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.

800D 06:08 G1X Mark III

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 800D or the G1X Mark III. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
