Canon D30 vs G3X
The Canon EOS-D30 and the Canon PowerShot G3 X are two digital cameras that were officially introduced, respectively, in May 2000 and June 2015. The D30 is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (D30) and an one-inch (G3X) sensor. The D30 has a resolution of 3.1 megapixels, whereas the G3X provides 20 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 G3 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.
The side-by-side display below illustrates the physical size and weight of the Canon D30 and the Canon G3 X. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G3 X is considerably smaller (41 percent) than the Canon D30. It is noteworthy in this context that the G3X is splash and dust-proof, while the D30 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 G3X 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 G3 X an one-inch sensor. The sensor area in the G3X is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the G3X offers a higher resolution of 20 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 2.41μm versus 10.29μm for the D30). However, it should be noted that the G3X is much more recent (by 15 years and 1 month) 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 G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 G3 X are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.
| DXO |
|2.||Canon G3 X||1-inch||20.0||5472||3648||1080/60p||21.4||12.3||521||63|
|7.||Canon G9 X||1-inch||20.0||5472||3648||1080/60p||21.5||12.3||495||63|

Many modern cameras are not only capable of taking still images, but can also record movies. The G3X indeed provides for movie recording, while the D30 does not. The highest resolution format that the G3X can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D30 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon D30, the Canon G3 X, and comparable cameras.
|2.||Canon G3 X||optional||n||3.2||1620||tilting||Y||1/2000s||5.9||Y||Y|
|7.||Canon G9 X||none||n||3.0||1040||fixed||Y||1/2000s||6.0||Y||Y|
|8.||Canon G7 X||none||n||3.0||1040||tilting||Y||1/2000s||6.5||Y||Y|
One feature that is present on the D30, but is missing on the G3X 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 G3X 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 G3X 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 G3 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|7.||Canon G9 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
|8.||Canon G7 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
It is notable that the G3X 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 G3X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G3X is a recent model that features in the current product line-up of Canon. In contrast, the D30 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D30 was succeeded by the Canon D60. 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 how do things add up? Which of the two cameras – the Canon D30 or the Canon G3 X – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- More modern: Reflects 15 years and 1 month of technical progress since the D30 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the G3X is the clear winner of the contest (18 : 7 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D30 and the G3X in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
