Canon 30D vs G3X

The Canon EOS 30D and the Canon PowerShot G3 X are two digital cameras that were officially introduced, respectively, in February 2006 and June 2015. The 30D is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (30D) and an one-inch (G3X) sensor. The 30D has a resolution of 8.2 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 30D 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 30D and the Canon G3 X. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon 30D vs Canon G3 X
Compare 30D versus G3X top
Comparison 30D or G3X rear

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 (38 percent) than the Canon 30D. It is noteworthy in this context that the G3X is splash and dust-proof, while the 30D 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 30D 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 30D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 30D gets 750 shots out of its BP-511A battery, while the G3X can take 300 images on a single charge of its NB-10L power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons 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 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 30D, 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 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 30D 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 30D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 30D and Canon G3 X sensor measures

Despite having a smaller sensor, the G3X offers a higher resolution of 20 megapixels, compared with 8.2 MP of the 30D. 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 6.42μm for the 30D). However, it should be noted that the G3X is much more recent (by 9 years and 3 months) than the 30D, 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 30D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The Canon EOS 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. 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.

30D versus G3X MP

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"). Of the two cameras under consideration, the G3X has a markedly higher DXO score than the 30D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.1 bits lower color depth, 1.5 EV in additional dynamic range, and 0.5 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G3X indeed provides for movie recording, while the 30D does not. The highest resolution format that the G3X can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 30D 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 adjacent table lists some of the other core features of the Canon 30D and Canon G3 X along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the 30D, 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 30D does not have a selfie-screen.

The 30D writes its imaging data to Compact Flash cards, while the G3X 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 30D 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 30D does not provide wifi capability.

Studio photographers will appreciate that the Canon 30D (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 30D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 30D was succeeded by the Canon 40D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what conclusions can be drawn? Is the Canon 30D better than the Canon G3 X or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 30D:

  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • 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 (1/8000s vs 1/2000s) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (750 versus 300) 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 February 2006).


Advantages of the Canon PowerShot G3 X:

  • More detail: Has more megapixels (20 vs 8.2MP), which boosts linear resolution by 56%.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 2).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 30D requires a separate lens.
  • More compact: Is smaller (123x77mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 30D).
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 9 years and 3 months of technical progress since the 30D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G3X is the clear winner of the contest (20 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

30D 08:20 G3X

How about other alternatives? Do the specifications of the Canon 30D 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 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 30D 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Notes: (+ +) 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. 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, please note that some of the review sites have changed their methodology and reporting over time.
