Canon 450D vs G3X

The Canon EOS 450D (called Canon XSi in some regions) and the Canon PowerShot G3 X are two digital cameras that were announced, respectively, in January 2008 and June 2015. The 450D is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (450D) and an one-inch (G3X) sensor. The 450D has a resolution of 12.2 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 450D and the Canon G3 X. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Canon 450D vs Canon G3 X
Compare 450D versus G3X top
Comparison 450D 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 notably smaller (25 percent) than the Canon 450D. It is noteworthy in this context that the G3X is splash and dust-proof, while the 450D 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 450D 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 450D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 450D gets 500 shots out of its Canon LP-E5 battery, while the G3X can take 300 images on a single charge of its Canon NB-10L power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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.

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. 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 450D 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.

Technology-wise, the G3X uses a more advanced image processing engine (DIGIC 6) than the 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 450D and Canon G3 X sensor measures

Despite having a smaller sensor, the G3X offers a higher resolution of 20 megapixels, compared with 12.2 MP of the 450D. 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 5.19μm for the 450D). However, it should be noted that the G3X is much more recent (by 7 years and 4 months) than the 450D, 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 450D are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.

The Canon EOS 450D 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.

In terms of underlying technology, the 450D 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.

450D versus G3X MP

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 450D 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 450D and Canon G3 X along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X has a touchscreen, while the 450D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 450D does not have a selfie-screen.

The 450D writes its imaging data to SDHC cards, while the G3X uses SDXC cards. The G3X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 450D cannot take advantage of Ultra High Speed SD cards.

Review summary

So how do things add up? Which of the two cameras – the Canon 450D or the Canon G3 X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 450D:

  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (500 versus 300) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in January 2008).


Advantages of the Canon PowerShot G3 X:

  • More detail: Has more megapixels (20 vs 12.2MP), which boosts linear resolution by 28%.
  • 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 3).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") 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 3.5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 450D requires a separate lens.
  • More compact: Is smaller (123x77mm vs 129x98mm) and will fit more readily into a bag.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 7 years and 4 months of technical progress since the 450D 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 : 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.

450D 06:18 G3X

How about other alternatives? Do the specifications of the Canon 450D 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 450D or the G3X. 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 where reviews by experts come in. 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.

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

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
