Canon G15 vs Olympus E-330

The Canon PowerShot G15 and the Olympus Evolt E-330 are two digital cameras that were revealed to the public, respectively, in September 2012 and January 2006. The G15 is a fixed lens compact, while the E-330 is a DSLR. The cameras are based on a 1/1.7-inch (G15) and a Four Thirds (E-330) sensor. The Canon has a resolution of 12 megapixels, whereas the Olympus provides 7.4 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 G15 and the Olympus Evolt E-330? 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 physical size and weight of the Canon G15 and the Olympus E-330 are illustrated in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

Size Canon G15 vs Olympus E-330
Compare G15 versus E-330 top
Comparison G15 or E-330 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-330 is considerably larger (50 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the E-330 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 E-330 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 E-330 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the G15 gets 350 shots out of its NB-10L battery, while the E-330 can take 750 images on a single charge of its BLM-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 G15 was launched at a lower price than the E-330, 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 imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G15 features a 1/1.7-inch sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Canon G15 and Olympus E-330 sensor measures

Despite having a smaller sensor, the Canon G15 offers a higher resolution of 12 megapixels, compared with 7.4 MP of the Olympus E-330. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.89μm versus 5.51μm for the E-330). However, it should be noted that the G15 is much more recent (by 6 years and 7 months) than the E-330, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G15 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G15 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 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 Olympus Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

Review summary

So how do things add up? Which of the two cameras – the Canon G15 or the Olympus E-330 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon PowerShot G15:

  • More detail: Offers more megapixels (12 vs 7.4MP) with a 28% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 1080/24p movies.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 215k dots).
  • Ready to shoot: Comes with a built-in lens, while the E-330 requires a separate lens.
  • More compact: Is smaller (107x76mm vs 140x87mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-330).
  • 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 modern: Reflects 6 years and 7 months of technical progress since the E-330 launch.

ilogo

Reasons to prefer the Olympus Evolt E-330:

  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (3 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 (750 versus 350) out of a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in January 2006).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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.

G15 10:10 E-330

How about other alternatives? Do the specifications of the Canon G15 and the Olympus E-330 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G15 or the E-330. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
