Canon G12 vs SX730
The Canon PowerShot G12 and the Canon PowerShot SX730 HS are two digital cameras that were announced, respectively, in September 2010 and April 2017. Both the G12 and the SX730 are fixed lens compact cameras that are based on a 1/1.7-inch (G12) and a 1/2.3-inch (SX730) sensor. The G12 has a resolution of 10 megapixels, whereas the SX730 provides 20.2 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 PowerShot G12 and the Canon PowerShot SX730 HS? 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 G12 and the Canon SX730. 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.
The SX730 can be obtained in two different colors (black, silver), while the G12 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX730 is notably smaller (17 percent) than the Canon G12. Moreover, the SX730 is markedly lighter (25 percent) than the G12. In this context, it is worth noting that neither the G12 nor the SX730 are weather-sealed.
Concerning battery life, the G12 gets 370 shots out of its NB-7L battery, while the SX730 can take 250 images on a single charge of its NB-13L power pack. The power pack in the SX730 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 SX730 was launched at a somewhat lower price (by 20 percent) than the G12, which makes it more attractive for photographers on a tight budget. 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 G12 features a 1/1.7-inch sensor and the Canon SX730 a 1/2.3-inch sensor. The sensor area in the SX730 is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, the SX730 uses a more advanced image processing engine (DIGIC 6) than the G12 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX730 offers a higher resolution of 20.2 megapixels, compared with 10 MP of the G12. 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 1.18μm versus 2.07μm for the G12). However, it should be noted that the SX730 is much more recent (by 6 years and 6 months) than the G12, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX730 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX730 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX730 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 Canon PowerShot G12 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Canon PowerShot SX730 HS are ISO 80 to ISO 3200 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX730 provides a better video resolution than the G12. It can shoot movie footage at 1080/60p, while the G12 is limited to 720/24p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G12 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX730 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G12 and Canon SX730 along with similar information for a selection of comparators.

Both the G12 and the SX730 have zoom lenses built in. The G12 has a 28-140mm f/2.8-4.5 optic and the SX730 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the SX730 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G12. The G12 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G12 and the SX730 write their files to SDXC 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 PowerShot G12 and Canon PowerShot SX730 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G12 has a hotshoe, while the SX730 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the G12 and the SX730 have been discontinued, but can regularly be found used on eBay. The G12 was replaced by the Canon G15, while the SX730 was followed by the Canon SX730 HS. 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? Which of the two cameras – the Canon G12 or the Canon SX730 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the SX730 is the clear winner of the contest (18 : 8 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G12 and the SX730 in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
