Canon T6i versus Canon G5 X

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Canon PowerShot G5 X are two digital cameras that were revealed to the public, respectively, in February 2015 and October 2015. The T6i is a DSLR, while the G5X is a fixed lens compact. The cameras are based on an APS-C (T6i) and an one-inch (G5X) sensor. The T6i has a resolution of 24 megapixel, whereas the G5X 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 G5 X

An illustration of the physical size and weight of the Canon T6i and the Canon G5 X is provided 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 – the T6i – 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 G5 X is considerably smaller (36 percent) than the Canon T6i. In this context, it is worth noting that neither the T6i nor the G5X are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G5X 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 G5X can take 210 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 T6i vs Canon G5 X

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon T6i features an APS-C sensor and the Canon G5 X an one-inch sensor. The sensor area in the G5X 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 G5 X sensor measures

With 24MP, the T6i offers a higher resolution than the G5X (20MP), but the T6i nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G5X) due to its larger sensor. However, the G5X is a somewhat more recent model (by 8 months) than the T6i, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

T6i versus G5X MP

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 can also record movies. 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 T6i vs Canon G5 X

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G5X has an electronic viewfinder (2360k dots), while the T6i 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 T6i and Canon G5 X 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.

The G5X 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 G5 X

So what is the bottom line? Which of the two cameras – the Canon T6i or the Canon G5 X – 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.
  • 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 (440 versus 210) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).


Arguments in favor of the Canon PowerShot G5 X:

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Faster burst: Shoots at higher frequency (5.9 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 (112x76mm 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 modern: Was introduced somewhat (8 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (7 points each). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

T6i 07:07 G5X

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 G5X. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
