Canon T7i versus Canon G7 X Mark II

The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Canon PowerShot G7 X Mark II are two digital cameras that were officially introduced, respectively, in February 2017 and February 2016. The T7i is a DSLR, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (T7i) and an one-inch (G7X Mark II) sensor. The T7i has a resolution of 24 megapixel, whereas the G7X Mark II 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 T7i vs Canon G7 X Mark II

The physical size and weight of the Canon T7i and the Canon G7 X Mark II 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 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 T7i – 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 G7 X Mark II is considerably smaller (51 percent) than the Canon T7i. In this context, it is worth noting that neither the T7i nor the G7X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens build in, whereas the T7i 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 T7i and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the T7i gets 600 shots out of its LP-E17 battery, while the G7X Mark II can take 265 images on a single charge of its NB-13L power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark II was launched at a lower price than the T7i, 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 T7i vs Canon G7 X Mark II

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 T7i features an APS-C sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II 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 T7i and Canon G7 X Mark II sensor measures

With 24MP, the T7i offers a higher resolution than the G7X Mark II (20MP), but the T7i nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the T7i is a somewhat more recent model (by 11 months) than the G7X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. 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: Canon T7i vs Canon G7 X Mark II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the T7i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon T7i and Canon G7 X Mark II along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

Both the T7i and the G7X Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G7X Mark II replaced the earlier Canon G7 X, while the T7i followed on from the Canon T6i.

Review summary: Canon T7i vs Canon G7 X Mark II

So how do things add up? Is there a clear favorite between the Canon T7i and the Canon G7 X Mark II? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon EOS Rebel T7i:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • 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 265) on a single battery charge.
  • More modern: Is somewhat more recent (announced 11 months after the G7X Mark II).


Advantages of the Canon PowerShot G7 X Mark II:

  • Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the T7i requires a separate lens.
  • More compact: Is smaller (106x61mm 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 T7i).
  • 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 heavily discounted: Has been on the market for longer (launched in February 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the T7i comes out slightly ahead of the G7X Mark II (8 : 7 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.

T7i 08:07 G7X Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the T7i or the G7X Mark II. 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 review scores listed above should be treated with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
