Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G12 and the Sony Alpha NEX-7? 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

The physical size and weight of the Canon G12 and the Sony NEX-7 are illustrated in the side-by-side display below. 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 measures 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 Sony NEX-7 is notably smaller (6 percent) than the Canon G12. In this context, it is worth noting that neither the G12 nor the NEX-7 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 NEX-7 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 NEX-7 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the G12 gets 370 shots out of its Canon NB-7L battery, while the NEX-7 can take 430 images on a single charge of its Sony NP-FW50 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 G12 was launched at a lower price than the NEX-7, 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 size of the imaging sensor is a crucial determinant 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. 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 more expensive and 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 Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 749 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.5. The sensor in the G12 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.

With 24MP, the NEX-7 offers a higher resolution than the G12 (10MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the NEX-7 is a somewhat more recent model (by 11 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 pixel-units.

The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 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 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 Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).

In terms of underlying technology, the G12 is build around a CCD sensor, while the NEX-7 uses a 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.

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"). Of the two cameras under consideration, the NEX-7 offers substantially better image quality than the G12 (overall score 34 points higher). The advantage is based on 3.7 bits higher color depth, 2.2 EV in additional dynamic range, and 2.7 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the NEX-7 provides a better video resolution than the G12. It can shoot movie footage at 1080/60i, while the Canon is limited to 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the NEX-7 has an electronic viewfinder (2359k dots), while the G12 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 G12, the Sony NEX-7, and comparable cameras.

It is notable that the NEX-7 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G12 does not feature such a mic input.

Both the G12 and the NEX-7 have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the NEX-7 does not have a direct successor. Further information on the features and operation of the G12 and NEX-7 can be found, respectively, in the Canon G12 Manual (free pdf) or the online Sony NEX-7 Manual.

Review summary

So what is the bottom line? Is the Canon G12 better than the Sony NEX-7 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot G12:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Ready to shoot: Has a lens built-in, whereas the NEX-7 requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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).

Reasons to prefer the Sony Alpha NEX-7:

• More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
• Better image quality: Scores substantially higher (34 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (3.7 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.2 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.7 stops ISO advantage).
• Better video: Provides higher definition movie capture (1080/60i vs 720/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (921k vs 461k dots).
• Faster burst: Shoots at higher frequency (10 vs 1.1 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (430 versus 370) out of a single battery charge.
• More modern: Was introduced somewhat (11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the NEX-7 is the clear winner of the contest (14 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

How about other alternatives? Do the specifications of the Canon G12 and the Sony NEX-7 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G12 or the NEX-7. 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 why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
