Canon T6s versus Canon G7 X Mark II

The Canon EOS Rebel T6s (called Canon 760D in some regions) and the Canon PowerShot G7 X Mark II are two digital cameras that were announced, respectively, in February 2015 and February 2016. The T6s is a DSLR, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (T6s) and an one-inch sensor. The T6s has a resolution of 24 megapixel, whereas the G7X Mark II provides 20 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon T6s and the Canon G7 X Mark II. 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. 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 T6s – represents 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 G7 X Mark II is considerably smaller (52 percent) than the Canon T6s. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. In this context, it is worth noting that neither the T6s 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 T6s 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 T6s 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. The G7X Mark II was launched at a lower price than the T6s, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T6s 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.

Sensor size

With 24MP, the T6s offers a higher resolution than the G7X Mark II (20MP), but the T6s nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G7X Mark II) due to its larger sensor. However, the G7X Mark II is a somewhat more recent model (by 1 year) than the T6s, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X Mark II provides a faster frame rate than the T6s. It can shoot movie footage at 1080/60p, while the T6s is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the T6s 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 following table reports on some other key feature differences and similarities of the Canon T6s, the Canon G7 X Mark II, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the T6s has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the T6s was succeeded by the Canon 77D.

Summary

So how do things add up? Is the Canon T6s better than the Canon G7 X Mark II or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS Rebel T6s:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has a 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 (440 versus 265) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

Advantages of the Canon PowerShot G7 X Mark II:

  • Better video: Provides higher movie framerates (1080/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the T6s requires a separate lens.
  • More compact: Is smaller (106x61mm vs 132x101mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the T6s).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the T6s emerges as the winner of the contest (9 : 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.

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 T6s or the G7X Mark II handle or perform in practice. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
