Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G12 and the Nikon D3200? 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 Nikon D3200. 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 D3200 can be obtained in two different colors (black, red), 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 Nikon D3200 is notably larger (41 percent) than the Canon G12. In this context, it is worth noting that neither the G12 nor the D3200 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 D3200 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 D3200 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the G12 gets 370 shots out of its Canon NB-7L battery, while the D3200 can take 540 images on a single charge of its Nikon EN-EL14 power pack.

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

Any camera decision will obviously take relative prices into account. 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 D3200, 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. 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 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 D3200 an APS-C sensor. The sensor area in the D3200 is 730 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 D3200 offers a 3:2 aspect.

With 24.1MP, the D3200 offers a higher resolution than the G12 (10MP), but the D3200 nevertheless has larger individual pixels (pixel pitch of 3.85μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the D3200 is a somewhat more recent model (by 1 year and 7 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 Nikon D3200 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3200 for good quality output (200 dots per inch) amounts to 30.1 x 20 inches or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inches or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inches or 50.9 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 Nikon D3200 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the G12 is build around a CCD sensor, while the D3200 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 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 D3200 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 EV in additional dynamic range, and 2.8 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D3200 provides a better video resolution than the G12. It can shoot movie footage at 1080/30p, 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. The G12 and the D3200 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 G12, the Nikon D3200, and comparable cameras.

It is notable that the D3200 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 D3200 have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the D3200 was followed by the Nikon D3300. Further information on the features and operation of the G12 and D3200 can be found, respectively, in the Canon G12 Manual (free pdf) or the online Nikon D3200 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G12 or the Nikon D3200 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot G12:

• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Ready to shoot: Comes with a built-in lens, while the D3200 requires a separate lens.
• More compact: Is smaller (112x76mm vs 125x96mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D3200).
• 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).

Arguments in favor of the Nikon D3200:

• More detail: Has more megapixels (24.1 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 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.8 stops ISO advantage).
• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• 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 (921k vs 461k dots).
• Faster burst: Shoots at higher frequency (4 vs 1.1 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (540 versus 370) out of a single battery charge.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the D3200 is the clear winner of the contest (14 : 7 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 Nikon D3200 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the G12 and the D3200 in practical situations. 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 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], 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 review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
