Canon 400D vs G1X
The Canon EOS 400D (called Canon XTi in some regions) and the Canon PowerShot G1 X are two digital cameras that were revealed to the public, respectively, in August 2006 and January 2012. The 400D is a DSLR, while the G1X is a fixed lens compact. The cameras are based on an APS-C (400D) and an 1.5-inch (G1X) sensor. The 400D has a resolution of 10.1 megapixels, whereas the G1X provides 14.2 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 400D and the Canon PowerShot G1 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 physical size and weight of the Canon 400D and the Canon G1 X are illustrated in the side-by-side display below. 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 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 G1 X is notably smaller (11 percent) than the Canon 400D. In this context, it is worth noting that neither the 400D nor the G1X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the 400D 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 400D 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. 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 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. 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. 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 400D features an APS-C sensor and the Canon G1 X an 1.5-inch sensor. The sensor area in the G1X is 20 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.85. The sensor in the 400D has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.
Technology-wise, the G1X uses a more advanced image processing engine (DIGIC 5) than the 400D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the G1X offers a higher resolution of 14.2 megapixels, compared with 10.1 MP of the 400D. 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 4.30μm versus 5.71μm for the 400D). However, it should be noted that the G1X is much more recent (by 5 years and 4 months) than the 400D, 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 G1 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X for good quality output (200 dots per inch) amounts to 21.8 x 16.3 inches or 55.3 x 41.5 cm, for very good quality (250 dpi) 17.4 x 13.1 inches or 44.2 x 33.2 cm, and for excellent quality (300 dpi) 14.5 x 10.9 inches or 36.8 x 27.6 cm. The corresponding values for the Canon 400D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G1 X are ISO 100 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
| DXO |
|2.||Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|5.||Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
Many modern cameras are not only capable of taking still images, but can also record movies. The G1X indeed provides for movie recording, while the 400D does not. The highest resolution format that the G1X can use is 1080/24p.
Beyond body and sensor, cameras can and do differ across a range of features. The 400D and the G1X 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 400D, the Canon G1 X, and comparable cameras.

The 400D writes its imaging data to Compact Flash cards, while the G1X 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 400D and Canon PowerShot G1 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 400D and the G1X have been discontinued, but can regularly be found used on eBay. The 400D was replaced by the Canon 450D, while the G1X was followed by the Canon G1X Mark II. 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? Which of the two cameras – the Canon 400D or the Canon G1 X – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS 400D:
- Faster burst: Shoots at higher frequency (3 vs 1.9 flaps/sec) to capture the decisive moment.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (370 versus 250) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Arguments in favor of the Canon PowerShot G1 X:
- More detail: Has more megapixels (14.2 vs 10.1MP), which boosts linear resolution by 16%.
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC II).
- Broader imaging potential: Can capture not only stills but also 1080/24p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Ready to shoot: Comes with an integrated lens, while the 400D requires a separate lens.
- More compact: Is smaller (117x81mm vs 127x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 400D).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Reflects 5 years and 4 months of technical progress since the 400D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G1X is the clear winner of the contest (11 : 4 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 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.
How about other alternatives? Do the specifications of the Canon 400D and the Canon G1 X 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 400D or the G1X. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
