Canon XTi vs Sony RX0
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Sony Cyber-shot DSC-RX0 are two digital cameras that were officially introduced, respectively, in August 2006 and August 2017. The XTi is a DSLR, while the RX0 is a fixed lens compact. The cameras are based on an APS-C (XTi) and an one-inch (RX0) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Sony provides 15.4 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 Rebel XTi and the Sony Cyber-shot DSC-RX0? 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 XTi and the Sony RX0. 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 Sony RX0 is considerably smaller (77 percent) than the Canon XTi. It is noteworthy in this context that the RX0 is splash and dust-proof, while the XTi does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 has a lens built in, whereas the XTi 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 XTi and their specifications in the Canon EF Lens Catalog.
The power pack in the RX0 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The RX0 was launched at a lower price than the XTi, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 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 RX0 offers a higher resolution of 15.4 megapixels, compared with 10.1 MP of the XTi. 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 2.74μm versus 5.71μm for the XTi). However, it should be noted that the RX0 is much more recent (by 11 years) than the XTi, 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 Sony RX0 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX0 for good quality output (200 dots per inch) amounts to 24 x 16 inches or 61 x 40.6 cm, for very good quality (250 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm, and for excellent quality (300 dpi) 16 x 10.7 inches or 40.6 x 27.1 cm. The corresponding values for the Canon XTi 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 Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 RX0 has a markedly higher DXO score than the XTi (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 0.3 stops of reduced low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The RX0 indeed provides for movie recording, while the XTi does not. The highest resolution format that the RX0 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the XTi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX0 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon XTi, the Sony RX0, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The XTi has one, while the RX0 does not. While the built-in flash of the XTi is not very powerful, it can at times be useful as a fill-in light.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX0 only has electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The XTi writes its imaging data to Compact Flash cards, while the RX0 uses micro SDXC or Memory Stick Micro 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 Rebel XTi and Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the XTi has a hotshoe, while the RX0 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the XTi and the RX0 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the RX0 was followed by the Sony RX0 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what conclusions can be drawn? Is there a clear favorite between the Canon XTi and the Sony RX0? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS Rebel XTi:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Larger screen: Has a bigger rear LCD (2.5" vs 1.5") for image review and settings control.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (370 versus 240) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Reasons to prefer the Sony Cyber-shot DSC-RX0:
- More detail: Has more megapixels (15.4 vs 10.1MP), which boosts linear resolution by 23%.
- Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- Faster burst: Shoots at higher frequency (5.5 vs 3 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Ready to shoot: Comes with an integrated lens, while the XTi requires a separate lens.
- More compact: Is smaller (59x41mm 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 XTi).
- Easier travel charging: Can be conveniently charged via its USB port.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 11 years of technical progress since the XTi launch.
If the count of relative strengths (bullet points above) is taken as a measure, the RX0 is the clear winner of the contest (16 : 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 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.

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 XTi and the RX0 in practical situations. 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 why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
