Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 650D and the Canon PowerShot G7 X Mark II? 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.

Body comparison

An illustration of the physical size and weight of the Canon 650D and the Canon G7 X Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 G7 X Mark II is considerably smaller (51 percent) than the Canon 650D. In this context, it is worth noting that neither the 650D 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 built in, whereas the 650D 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 650D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 650D gets 440 shots out of its Canon LP-E8 battery, while the G7X Mark II can take 265 images on a single charge of its Canon NB-13L power pack. The power pack in the G7X Mark II can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 G7X Mark II was launched at a lower price than the 650D, despite having a lens built 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 650D 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.

Technology-wise, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the 650D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the G7X Mark II offers a higher resolution of 20 megapixels, compared with 17.9 MP of the 650D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.31μm for the 650D). However, it should be noted that the G7X Mark II is much more recent (by 3 years and 8 months) than the 650D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G7 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon 650D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The 650D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 650D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot G7 X Mark II are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

In terms of underlying technology, the 650D is build around a CMOS sensor, while the G7X Mark II 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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. 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 650D. It can shoot movie footage at 1080/60p, while the 650D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 650D 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 650D and Canon G7 X Mark II along with similar information for a selection of comparators.

The Canon G7 X Mark II has 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 650D and the G7X Mark II 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.

Connectivity comparison

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 650D and Canon PowerShot G7 X Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 650D has a hotshoe, while the G7X Mark II does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the 650D and the G7X Mark II have been discontinued, but can regularly be found used on ebay. The 650D was replaced by the Canon 700D, while the G7X Mark II was followed by the Canon G7 X Mark III. Further information on the features and operation of the 650D and G7X Mark II can be found, respectively, in the Canon 650D Manual (free pdf) or the online Canon G7 X Mark II Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 650D and the Canon G7 X Mark II? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS 650D:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• 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 (440 versus 265) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in June 2012).

Advantages of the Canon PowerShot G7 X Mark II:

• More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
• Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 5).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the 650D requires a separate lens.
• More compact: Is smaller (106x61mm vs 133x100mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 650D).
• 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.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 3 years and 8 months of technical progress since the 650D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark II comes out slightly ahead of the 650D (14 : 13 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 650D and the Canon G7 X Mark II 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 650D and the G7X Mark II in practical situations. 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.

Expert reviews

This is where reviews by experts come in. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
