Canon 77D vs G5X
The Canon EOS 77D and the Canon PowerShot G5 X are two digital cameras that were announced, respectively, in February 2017 and October 2015. The 77D is a DSLR, while the G5X is a fixed lens compact. The cameras are based on an APS-C (77D) and an one-inch (G5X) sensor. The 77D has a resolution of 24 megapixels, whereas the G5X provides 20 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 77D and the Canon PowerShot G5 X? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Canon 77D and the Canon G5 X. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
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 (35 percent) than the Canon 77D. In this context, it is worth noting that neither the 77D 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 built in, whereas the 77D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 77D and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the 77D gets 600 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 power pack in the G5X can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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. The G5X was launched at a lower price than the 77D, despite having a lens built in. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 77D 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.
In terms of chip-set technology, the 77D uses a more advanced image processing engine (DIGIC 7) than the G5X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the 77D offers a higher resolution than the G5X (20MP), but the 77D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the 77D is a somewhat more recent model (by 1 year and 4 months) than the G5X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 77D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 77D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon G5 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 77D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Canon PowerShot G5 X are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.
In terms of underlying technology, the 77D is build around a CMOS sensor, while the G5X uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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"). Of the two cameras under review, the 77D provides substantially higher image quality than the G5X, with an overall score that is 16 points higher. This advantage is based on 2.2 bits higher color depth, 1 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. 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).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5X has an electronic viewfinder (2360k dots), while the 77D 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 following table reports on some other key feature differences and similarities of the Canon 77D, the Canon G5 X, and comparable cameras.

One feature that is present on the 77D, but is missing on the G5X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The Canon 77D and the Canon G5 X both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the 77D and the G5X write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 77D and Canon PowerShot G5 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D has a microphone port, which is missing on the G5X. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the 77D and the G5X have been discontinued, but can regularly be found used on ebay. The G5X was replaced by the Canon G5 X Mark II, while the 77D does not have a direct successor. Further information on the features and operation of the 77D and G5X can be found, respectively, in the Canon 77D Manual (free pdf) or the online Canon G5 X Manual.
So what is the bottom line? Is the Canon 77D better than the Canon G5 X or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 77D:
- More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
- Better image quality: Scores substantially higher (16 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.2 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (600 versus 210) on a single battery charge.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Is somewhat more recent (announced 1 year and 4 months after the G5X).
Reasons to prefer the Canon PowerShot G5 X:
- More framing info: Has an electronic viewfinder that displays shooting data.
- Ready to shoot: Comes with an integrated lens, while the 77D requires a separate lens.
- More compact: Is smaller (112x76mm vs 131x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 77D).
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (15 : 8 points). 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 77D and the Canon G5 X place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 77D or the G5X 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 why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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.
