Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 and the Nikon D3300? 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 G15 and the Nikon D3300 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The D3300 can be obtained in three different colors (black, grey, red), while the G15 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 D3300 is considerably larger (49 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the D3300 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the D3300 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 D3300 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the D3300 can take 700 images on a single charge of its Nikon EN-EL14a power pack.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. 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 G15 features a 1/1.7-inch sensor and the Nikon D3300 an APS-C sensor. The sensor area in the D3300 is 753 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 G15 has a native 4:3 aspect ratio, while the one in the D3300 offers a 3:2 aspect.

With 24MP, the D3300 offers a higher resolution than the G15 (12MP), but the D3300 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.89μm for the G15) due to its larger sensor. Moreover, the D3300 is a somewhat more recent model (by 1 year and 3 months) than the G15, and its sensor might 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 D3300 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D3300 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3300 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 G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon D3300 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 D3300 offers substantially better image quality than the G15 (overall score 36 points higher). The advantage is based on 4.4 bits higher color depth, 1.3 EV in additional dynamic range, and 3.1 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D3300 provides a faster frame rate than the G15. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G15 and the D3300 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 adjacent table lists some of the other core features of the Canon G15 and Nikon D3300 along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the G15 and the D3300 write their files to SDXC cards. The D3300 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G15 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 G15 and Nikon D3300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D3300 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G15 does not feature such a mic input.

Both the G15 and the D3300 have been discontinued, but can regularly be found used on ebay. The G15 was replaced by the Canon G16, while the D3300 was followed by the Nikon D3400. Further information on the features and operation of the G15 and D3300 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Nikon D3300 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon G15 and the Nikon D3300? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot G15:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Ready to shoot: Comes with a built-in lens, while the D3300 requires a separate lens.
• More compact: Is smaller (107x76mm vs 124x98mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D3300).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been on the market for longer (launched in September 2012).

Advantages of the Nikon D3300:

• More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (36 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4.4 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (3.1 stops ISO advantage).
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Faster burst: Shoots at higher frequency (5 vs 2.1 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 (700 versus 350) 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 3 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the D3300 is the clear winner of the contest (13 : 6 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 G15 and the Nikon D3300 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 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 G15 or the D3300 perform in practice. 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 where reviews by experts come in. 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.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
