Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-D30 and the Canon PowerShot G16? 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 D30 and the Canon G16 are illustrated 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G16 is considerably smaller (48 percent) than the Canon D30. In this context, it is worth noting that neither the D30 nor the G16 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 has a lens built in, whereas the D30 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 D30 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the D30 gets 540 shots out of its Canon BP-511 battery, while the G16 can take 360 images on a single charge of its Canon NB-10L power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G16 was launched at a lower price than the D30, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon D30 features an APS-C sensor and the Canon G16 a 1/1.7-inch sensor. The sensor area in the G16 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.65. The sensor in the D30 has a native 3:2 aspect ratio, while the one in the G16 offers a 4:3 aspect.

Despite having a smaller sensor, the G16 offers a higher resolution of 12 megapixels, compared with 3.1 MP of the D30. 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 1.87μm versus 10.29μm for the D30). However, it should be noted that the G16 is much more recent (by 13 years and 3 months) than the D30, 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 G16 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G16 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 Canon D30 are 10.8 x 7.2 inches or 27.4 x 18.3 cm for good quality, 8.6 x 5.8 inches or 21.9 x 14.6 cm for very good quality, and 7.2 x 4.8 inches or 18.3 x 12.2 cm for excellent quality prints.

The Canon EOS-D30 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G16 are ISO 80 to ISO 12800 (no boost).

In terms of underlying technology, the D30 is build around a CMOS sensor, while the G16 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The G16 indeed provides for movie recording, while the D30 does not. The highest resolution format that the G16 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D30 and the G16 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 D30, the Canon G16, and comparable cameras.

One feature that is present on the D30, but is missing on the G16 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Canon G16 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 D30 writes its imaging data to Compact Flash cards, while the G16 uses 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 EOS-D30 and Canon PowerShot G16 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D30 does not provide wifi capability.

Studio photographers will appreciate that the Canon D30 (unlike the G16) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D30 and the G16 have been discontinued, but can regularly be found used on ebay. The D30 was replaced by the Canon D60, while the G16 does not have a direct successor. Further information on the features and operation of the D30 and G16 can be found, respectively, in the Canon D30 Manual (free pdf) or the online Canon G16 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon D30 and the Canon G16? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-D30:

• 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.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster burst: Shoots at higher frequency (3 vs 2.2 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (540 versus 360) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in May 2000).

Arguments in favor of the Canon PowerShot G16:

• More detail: Has more megapixels (12 vs 3.1MP), which boosts linear resolution by 93%.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (922k vs 114k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the D30 requires a separate lens.
• More compact: Is smaller (109x76mm vs 150x107mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the D30).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 13 years and 3 months of technical progress since the D30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G16 emerges as the winner of the match-up (13 : 10 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 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 D30 and the Canon G16 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 D30 and the G16 in practical situations. 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.

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

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. Thus, a score needs to be put into the context of the launch date and the launch price 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, please note that some of the review sites have changed their methodology and reporting over time.
