Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-D30 and the Canon PowerShot G1 X? 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 D30 and the Canon G1 X is provided in the side-by-side display below. 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.

Compare D30 versus G1X top
Comparison D30 or G1X rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X is considerably smaller (41 percent) than the Canon D30. In this context, it is worth noting that neither the D30 nor the G1X are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X 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 BP-511 battery, while the G1X can take 250 images on a single charge of its NB-10L power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Note: 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 G1X 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. 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. 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 D30 features an APS-C sensor and the Canon G1 X an 1.5-inch sensor. The sensor area in the G1X is 20 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.85. The sensor in the D30 has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.

Canon D30 and Canon G1 X sensor measures

Despite having a smaller sensor, the G1X offers a higher resolution of 14.2 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 4.30μm versus 10.29μm for the D30). However, it should be noted that the G1X is much more recent (by 11 years and 7 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 G1 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X for good quality output (200 dots per inch) amounts to 21.8 x 16.3 inches or 55.3 x 41.5 cm, for very good quality (250 dpi) 17.4 x 13.1 inches or 44.2 x 33.2 cm, and for excellent quality (300 dpi) 14.5 x 10.9 inches or 36.8 x 27.6 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 G1 X are ISO 100 to ISO 12800 (no boost).

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.

D30 versus G1X MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 are not only capable of taking still images, but also of capturing video footage. The G1X indeed provides for movie recording, while the D30 does not. The highest resolution format that the G1X can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D30 and the G1X 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 G1 X, and comparable cameras.

One feature that is present on the D30, but is missing on the G1X 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 G1X has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D30 does not have a selfie-screen.

The D30 writes its imaging data to Compact Flash cards, while the G1X 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 G1 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon D30 (unlike the G1X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D30 and the G1X have been discontinued, but can regularly be found used on ebay. The D30 was replaced by the Canon D60, while the G1X was followed by the Canon G1X Mark II. Further information on the features and operation of the D30 and G1X can be found, respectively, in the Canon D30 Manual (free pdf) or the online Canon G1 X Manual.

Review summary

So how do things add up? Is the Canon D30 better than the Canon G1 X or vice versa? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS-D30:

  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster burst: Shoots at higher frequency (3 vs 1.9 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 250) 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 G1 X:

  • More detail: Has more megapixels (14.2 vs 3.1MP), which boosts linear resolution by 110%.
  • Broader imaging potential: Can capture not only stills but also 1080/24p 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).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Ready to shoot: Comes with an integrated lens, while the D30 requires a separate lens.
  • More compact: Is smaller (117x81mm 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).
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 11 years and 7 months of technical progress since the D30 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G1X is the clear winner of the contest (13 : 6 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.

D30 06:13 G1X

How about other alternatives? Do the specifications of the Canon D30 and the Canon G1 X 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 remains incomplete and does no justice, for example, to the way the D30 or the G1X 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 why hands-on reviews by experts are important. 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
