Canon 650D versus Canon G7 X
The Canon EOS 650D (called Canon T4i in some regions) and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in June 2012 and September 2014. The 650D is a DSLR, while the G7X is a fixed lens compact. The cameras are based on an APS-C (650D) and an one-inch sensor. The 650D has a resolution of 17.9 megapixel, whereas the G7X provides 20 MP.
The physical size and weight of the Canon 650D and the Canon G7 X are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 650D – 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 G7 X is considerably smaller (54 percent) than the Canon 650D. In this context, it is worth noting that neither the 650D nor the G7X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens build 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 find an overview of optics for the 650D 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 was launched at a lower price than the 650D, 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.
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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 650D features an APS-C sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X 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.
Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixel, compared with 17.9 MP of the 650D. This megapixel 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 is much more recent (by 2 years and 3 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.
For most cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under consideration, the G7X has a markedly higher DXO score than the 650D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1.3 bits higher color depth, 1.5 EV in additional dynamic range, 0.4 stops of reduced 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7X provides a faster frame rate than the 650D. It can shoot movie footage at 1080/60p, while the 650D is limited to 1080/30p.
Beyond 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 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 650D, the Canon G7 X, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 650D and the G7X have been discontinued, but can regularly be found used on ebay. The 650D was replaced by the Canon 700D, while the G7X was followed by the Canon G7 X Mark II.
So what is the bottom line? Is there a clear favorite between the Canon 650D and the Canon 650D? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS 650D:
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- 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 210) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in June 2012).
Arguments in favor of the Canon PowerShot G7 X:
- More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
- Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
- Faster burst: Shoots at higher frequency (6.5 vs 5 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with an integrated lens, while the 650D requires a separate lens.
- More compact: Is smaller (103x60mm vs 133x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens build in (unlike the 650D).
- More affordable: Was introduced at a lower price, despite coming with a build-in lens.
- More modern: Reflects 2 years and 3 months of technical progress since the 650D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the G7X is the clear winner of the contest (11 : 7 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 650D or the G7X. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
