Canon 650D vs G12
The Canon EOS 650D (called Canon T4i in some regions) and the Canon PowerShot G12 are two digital cameras that were revealed to the public, respectively, in June 2012 and September 2010. The 650D is a DSLR, while the G12 is a fixed lens compact. The cameras are based on an APS-C (650D) and a 1/1.7-inch (G12) sensor. The 650D has a resolution of 17.9 megapixels, whereas the G12 provides 10 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 650D and the Canon PowerShot G12? 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 650D and the Canon G12. 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 the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G12 is considerably smaller (36 percent) than the Canon 650D. In this context, it is worth noting that neither the 650D nor the G12 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 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.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 G12 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 G12 a 1/1.7-inch sensor. The sensor area in the G12 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.6. The sensor in the 650D has a native 3:2 aspect ratio, while the one in the G12 offers a 4:3 aspect.
In terms of chip-set technology, the 650D uses a more advanced image processing engine (DIGIC 5) than the G12 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 17.9MP, the 650D offers a higher resolution than the G12 (10MP), but the 650D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the 650D is a somewhat more recent model (by 1 year and 8 months) than the G12, 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 650D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 650D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 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 G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 review, the 650D provides substantially higher image quality than the G12, with an overall score that is 15 points higher. This advantage is based on 1.3 bits higher color depth, and 2.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 650D provides a higher video resolution than the G12. It can shoot video footage at 1080/30p, while the G12 is limited to 720/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The 650D and the G12 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Canon 650D, the Canon G12, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 650D has a touchscreen, while the G12 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The 650D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the G12 does not have a selfie-screen.
Concerning the storage of imaging data, both the 650D and the G12 write their files to SDXC cards. The 650D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G12 cannot take advantage of Ultra High Speed SD cards.
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 G12 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 microphone port, which is missing on the G12. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the 650D and the G12 have been discontinued, but can regularly be found used on eBay. The G12 was replaced by the Canon G15, while the 650D was followed by the Canon 700D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Is there a clear favorite between the Canon 650D and the Canon G12? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 650D:

- More modern: Is somewhat more recent (announced 1 year and 8 months after the G12).
Reasons to prefer the Canon PowerShot G12:
- Ready to shoot: Comes with an integrated lens, while the 650D requires a separate lens.
- More compact: Is smaller (112x76mm 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).
- 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 September 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the 650D is the clear winner of the match-up (17 : 6 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 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 650D or the G12 perform in practice. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
