Canon G12 vs Sony A7S

The Canon PowerShot G12 and the Sony Alpha A7S are two digital cameras that were announced, respectively, in September 2010 and April 2014. The G12 is a fixed lens compact, while the A7S is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (G12) and a full frame (A7S) sensor. The Canon has a resolution of 10 megapixels, whereas the Sony provides 12 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 Sony Alpha A7S? 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 side-by-side display below illustrates the physical size and weight of the Canon G12 and the Sony A7S. 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 measures are rounded to the nearest millimeter.

Compare G12 versus A7S top
Comparison G12 or A7S rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S is notably larger (40 percent) than the Canon G12. It is noteworthy in this context that the A7S is splash and dust-proof, while the G12 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 has a lens built in, whereas the A7S 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 A7S and their specifications in the Sony FE Lens Catalog.

The power pack in the A7S 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 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 camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 A7S, 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 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 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 Sony A7S a full frame sensor. The sensor area in the A7S is 1891 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.0. The sensor in the G12 has a native 4:3 aspect ratio, while the one in the A7S offers a 3:2 aspect.

Canon G12 and Sony A7S sensor measures

With 12MP, the A7S offers a higher resolution than the G12 (10MP), but the A7S nevertheless has larger individual pixels (pixel pitch of 8.45μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the A7S is a much more recent model (by 3 years and 6 months) than the G12, and its sensor will 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 A7S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7S for good quality output (200 dots per inch) amounts to 21.2 x 14.2 inch or 53.8 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inch or 43.1 x 28.8 cm, and for excellent quality (300 dpi) 14.1 x 9.4 inch or 35.9 x 24 cm. The corresponding values for the Canon G12 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch 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 A7S are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

G12 versus A7S MP

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 consideration, the A7S offers substantially better image quality than the G12 (overall score 40 points higher). The advantage is based on 3.5 bits higher color depth, 2 EV in additional dynamic range, and 4.5 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7S provides a better video resolution than the G12. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/24p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S has an electronic viewfinder (2400k 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.

One difference between the cameras concerns the presence of an on-board flash. The G12 has one, while the A7S does not. While the built-in flash of the G12 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The G12 writes its imaging data to SDXC cards, while the A7S uses SDXC or Memory Stick PRO Duo cards. The A7S 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.

 

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 PowerShot G12 and Sony Alpha A7S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G12 does not offer wifi capability.

Both the G12 and the A7S have been discontinued, but can regularly be found used on eBay. The G12 was replaced by the Canon G15, while the A7S was followed by the Sony A7S II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.


Review summary

So what is the bottom line? Which of the two cameras – the Canon G12 or the Sony A7S – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages 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 A7S requires a separate lens.
  • More compact: Is smaller (112x76mm vs 127x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the A7S).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in September 2010).

ilogo

Reasons to prefer the Sony Alpha A7S:

  • More detail: Has more megapixels (12 vs 10MP), which boosts linear resolution by 12%.
  • Better image quality: Scores substantially higher (40 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (4.5 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while 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 shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 1.1 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 3 years and 6 months of technical progress since the G12 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7S is the clear winner of the contest (20 : 9 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.

G12 09:20 A7S

How about other alternatives? Do the specifications of the Canon G12 and the Sony A7S 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 A7S. 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
