Canon 10D vs G3X
The Canon EOS 10D and the Canon PowerShot G3 X are two digital cameras that were revealed to the public, respectively, in February 2003 and June 2015. The 10D is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (10D) and an one-inch (G3X) sensor. The 10D has a resolution of 6.3 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 10D 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.
An illustration of the physical size and weight of the Canon 10D and the Canon G3 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 measures 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 10D. It is noteworthy in this context that the G3X is splash and dust-proof, while the 10D 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 10D 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 10D 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.

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 G3X was launched at a lower price than the 10D, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 10D features an APS-C sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 66 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.
Technology-wise, the G3X uses a more advanced image processing engine (DIGIC 6) than the 10D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the G3X offers a higher resolution of 20 megapixels, compared with 6.3 MP of the 10D. 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 7.38μm for the 10D). However, it should be noted that the G3X is much more recent (by 12 years and 3 months) than the 10D, 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 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.
The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. 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.
In terms of underlying technology, the 10D is build around a CMOS sensor, while the G3X 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the G3X has a markedly higher DXO score than the 10D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 1.4 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. 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 G3X indeed provides for movie recording, while the 10D 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 range of features. For example, the 10D 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 table below summarizes some of the other core capabilities of the Canon 10D and Canon G3 X in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 10D, 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 10D does not have a selfie-screen.
The 10D 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 10D and Canon PowerShot G3 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 10D does not provide wifi capability.
Studio photographers will appreciate that the Canon 10D (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 10D has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 10D was succeeded by the Canon 20D. Further information on the features and operation of the 10D and G3X can be found, respectively, in the Canon 10D Manual (free pdf) or the online Canon G3 X Manual.
So what is the bottom line? Which of the two cameras – the Canon 10D 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.
Advantages of the Canon EOS 10D:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.

- More modern: Reflects 12 years and 3 months of technical progress since the 10D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G3X is the clear winner of the contest (21 : 7 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 10D and the Canon G3 X place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 10D or the G3X. 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 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], 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
