Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 and the Olympus Stylus 1? 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 G15 and the Olympus Stylus 1. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus Stylus 1 is notably larger (24 percent) than the Canon G15. Moreover, the Stylus 1 is markedly heavier (14 percent) than the G15. In this context, it is worth noting that neither the G15 nor the Stylus 1 are weather-sealed.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the Stylus 1 can take 410 images on a single charge of its Olympus BLS-5 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 obviously take relative prices into account. 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 G15 was launched at a markedly lower price (by 29 percent) than the Stylus 1, which puts it into a different market segment. 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. 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.

Both cameras under consideration feature a 1/1.7-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 4.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the G15 offers a slightly higher resolution of 12 megapixels, compared with 11.8 MP of the Stylus 1. This megapixels advantage translates into a 0.8 percent gain in linear resolution. On the other hand, these sensor specs imply that the G15 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.89μm versus 1.91μm for the Stylus 1). Moreover, it should be noted that the Stylus 1 is a somewhat more recent model (by 1 year and 1 month) than the G15, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the Stylus 1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Olympus Stylus 1 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the G15 is build around a CMOS sensor, while the Stylus 1 uses a BSI-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 Stylus 1 has a markedly higher DXO score than the G15 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.1 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 Stylus 1 provides a faster frame rate than the G15. It can shoot movie footage at 1080/30p, while the Canon is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Stylus 1 has an electronic viewfinder (1440k dots), while the G15 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 G15, the Olympus Stylus 1, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Stylus 1 has a touchscreen, while the G15 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Olympus Stylus 1 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.

Both the G15 and the Stylus 1 have zoom lenses built in. The G15 has a 28-140mm f/1.8-2.8 optic and the Stylus 1 offers a 28-300mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Olympus provide the same view at the wide-angle end, but the Olympus has more tele-photo reach at the long end. The G15 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G15 and the Stylus 1 write their files to SDXC 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 Olympus Stylus 1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Stylus 1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G15 does not provide wifi capability.

Both the G15 and the Stylus 1 have been discontinued, but can regularly be found used on ebay. The G15 was replaced by the Canon G16, while the Stylus 1 was followed by the Olympus Stylus 1s. Further information on the features and operation of the G15 and Stylus 1 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Olympus Stylus 1 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon G15 and the Olympus Stylus 1? 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.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• More compact: Is smaller (107x76mm vs 116x87mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 50g or 12 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2012).

Reasons to prefer the Olympus Stylus 1:

• 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 video: Provides higher movie framerates (1080/30p versus 1080/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (7 vs 2.1 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the Stylus 1 is the clear winner of the contest (13 : 8 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 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 Olympus Stylus 1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G15 and the Stylus 1 in practical situations. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
