Canon T6i versus Canon G7 X Mark II

The Canon EOS Rebel T6i (called Canon 750D 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 T6i is a DSLR, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (T6i) and an one-inch (G7X Mark II) sensor. The T6i 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 T6i vs Canon G7 X Mark II

The physical size and weight of the Canon T6i and the Canon G7 X Mark II are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 T6i – 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 T6i. In this context, it is worth noting that neither the T6i 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 T6i 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 T6i and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the T6i gets 440 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 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. The G7X Mark II was launched at a lower price than the T6i, 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: Canon T6i vs Canon G7 X Mark II

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

Of the two cameras under consideration, the Canon T6i 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 T6i and Canon G7 X Mark II sensor measures

With 24MP, the T6i offers a higher resolution than the G7X Mark II (20MP), but the T6i 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 T6i, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon T6i vs Canon G7 X Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T6i 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 table below summarizes some of the other core capabilities of the Canon T6i and Canon G7 X Mark II in connection with corresponding information for a sample of similar 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 T6i has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the T6i was succeeded by the Canon T7i.

Review summary: Canon T6i vs Canon G7 X Mark II

So what is the bottom line? Which of the two cameras – the Canon T6i or the Canon G7 X Mark II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS Rebel T6i:

  • 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.
  • 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 (440 versus 265) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).


Reasons to prefer the Canon PowerShot G7 X Mark II:

  • 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 T6i 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 T6i).
  • 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 modern: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the T6i 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.

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 T6i or the G7X Mark II. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
