Canon D30 vs G12
The Canon EOS-D30 and the Canon PowerShot G12 are two digital cameras that were officially introduced, respectively, in May 2000 and September 2010. The D30 is a DSLR, while the G12 is a fixed lens compact. The cameras are based on an APS-C (D30) and a 1/1.7-inch (G12) sensor. The D30 has a resolution of 3.1 megapixels, whereas the G12 provides 10 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 EOS-D30 and the Canon PowerShot G12? 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.
An illustration of the physical size and weight of the Canon D30 and the Canon G12 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G12 is considerably smaller (47 percent) than the Canon D30. In this context, it is worth noting that neither the D30 nor the G12 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 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.
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 G12 was launched at a lower price than the D30, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon D30 features an APS-C sensor and the Canon G12 a 1/1.7-inch sensor. The sensor area in the G12 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.6. The sensor in the D30 has a native 3:2 aspect ratio, while the one in the G12 offers a 4:3 aspect.
Despite having a smaller sensor, the G12 offers a higher resolution of 10 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 2.07μm versus 10.29μm for the D30). However, it should be noted that the G12 is much more recent (by 10 years and 4 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 G12 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G12 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inches or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inches or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inches or 30.9 x 23.2 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 G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.
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"). 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 can also record movies. The G12 indeed provides for movie recording, while the D30 does not. The highest resolution format that the G12 can use is 720/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The D30 and the G12 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 G12, and comparable cameras.

One feature that is present on the D30, but is missing on the G12 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 D30 writes its imaging data to Compact Flash cards, while the G12 uses SDXC cards.
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 G12 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 G12) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D30 and the G12 have been discontinued, but can regularly be found used on eBay. The D30 was replaced by the Canon D60, while the G12 was followed by the Canon G15. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon D30 and the Canon G12? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of 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.

If the count of relative strengths (bullet points above) is taken as a measure, the G12 emerges as the winner of the match-up (12 : 10 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 D30 and the Canon G12 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 G12 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.
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.
