Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G12 and the Nikon 1 V3? 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

An illustration of the physical size and weight of the Canon G12 and the Nikon 1 V3 is provided 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 Nikon 1 V3 is notably smaller (15 percent) than the Canon G12. In this context, it is worth noting that neither the G12 nor the V3 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 V3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the G12 gets 370 shots out of its Canon NB-7L battery, while the V3 can take 310 images on a single charge of its Nikon EN-EL20a power pack.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G12 was launched at a lower price than the V3, despite having a lens built in. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 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 Nikon 1 V3 an one-inch sensor. The sensor area in the V3 is 170 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 2.7. The sensor in the G12 has a native 4:3 aspect ratio, while the one in the V3 offers a 3:2 aspect.

With 18.2MP, the V3 offers a higher resolution than the G12 (10MP), but the V3 nevertheless has larger individual pixels (pixel pitch of 2.52μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the V3 is a much more recent model (by 3 years and 5 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. Coming back to sensor resolution, it should be mentioned that the V3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon 1 V3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the V3 for good quality output (200 dots per inch) amounts to 26.2 x 17.4 inches or 66.4 x 44.3 cm, for very good quality (250 dpi) 20.9 x 14 inches or 53.2 x 35.4 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.3 x 29.5 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 V3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 Nikon 1 V3 are ISO 160 to ISO 12800 (no boost).

In terms of underlying technology, the G12 is build around a CCD sensor, while the V3 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.

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 V3 has a markedly higher DXO score than the G12 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.5 EV of lower dynamic range, and 1.3 stops in additional 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 V3 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

Beyond 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 V3 relies on live view and the rear LCD for framing. That said, the V3 can be equipped with an optional viewfinder – the DF-N1000. The following table reports on some other key feature differences and similarities of the Canon G12, the Nikon 1 V3, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The V3 has a touchscreen, while the G12 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 V3 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 Nikon 1 V3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The G12 writes its imaging data to SDXC cards, while the V3 uses micro SDXC cards. The V3 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 Nikon 1 V3 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 V3 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G12 and the V3 have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the V3 does not have a direct successor. Further information on the features and operation of the G12 and V3 can be found, respectively, in the Canon G12 Manual (free pdf) or the online Nikon 1 V3 Manual.

Review summary

So what is the bottom line? Is the Canon G12 better than the Nikon 1 V3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon PowerShot G12:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 V3 requires a separate lens.
• Longer lasting: Can take more shots (370 versus 310) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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).

Advantages of the Nikon 1 V3:

• More detail: Has more megapixels (18.2 vs 10MP), which boosts linear resolution by 38%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
• Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• 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 (1037k vs 461k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (60 vs 1.1 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (111x65mm vs 112x76mm) and will fit more readily into a bag.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 5 months of technical progress since the G12 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the V3 is the clear winner of the contest (18 : 9 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 before making a camera decision. 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 Nikon 1 V3 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G12 or the V3 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

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 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.
