Canon XT vs Sony RX100
The Canon EOS Rebel XT (called Canon 350D in some regions) and the Sony Cyber-shot DSC-RX100 are two digital cameras that were officially introduced, respectively, in February 2005 and June 2012. The XT is a DSLR, while the RX100 is a fixed lens compact. The cameras are based on an APS-C (XT) and an one-inch (RX100) sensor. The Canon has a resolution of 8 megapixels, whereas the Sony 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 Rebel XT and the Sony Cyber-shot DSC-RX100? 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 XT and the Sony RX100. 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.
The XT can be obtained in two different colors (black, silver), while the RX100 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 is considerably smaller (50 percent) than the Canon XT. In this context, it is worth noting that neither the XT nor the RX100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 has a lens built in, whereas the XT 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 XT and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the XT gets 400 shots out of its NB-2LH battery, while the RX100 can take 330 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 RX100 was launched at a lower price than the XT, 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 imaging sensor is a crucial determinant 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 XT features an APS-C sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 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 RX100 offers a higher resolution of 20 megapixels, compared with 8 MP of the XT. 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 6.41μm for the XT). However, it should be noted that the RX100 is much more recent (by 7 years and 3 months) than the XT, 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 RX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 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 XT are 17.3 x 11.5 inches or 43.9 x 29.3 cm for good quality, 13.8 x 9.2 inches or 35.1 x 23.4 cm for very good quality, and 11.5 x 7.7 inches or 29.3 x 19.5 cm for excellent quality prints.
The Canon EOS Rebel XT has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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 RX100 has a markedly higher DXO score than the XT (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1.6 EV in additional dynamic range, and 0.7 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 also of capturing video footage. The RX100 indeed provides for movie recording, while the XT does not. The highest resolution format that the RX100 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the XT has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX100 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 XT, the Sony RX100, and comparable cameras.

It is notable that the XT has a hotshoe, while the RX100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the XT and the RX100 have been discontinued, but can regularly be found used on ebay. The XT was replaced by the Canon Xti, while the RX100 was followed by the Sony RX100 II. Further information on the features and operation of the XT and RX100 can be found, respectively, in the Canon XT Manual (free pdf) or the online Sony RX100 Manual.
So how do things add up? Which of the two cameras – the Canon XT or the Sony RX100 – 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 Rebel XT:
- Better low-light sensitivity: Requires less light for good images (0.7 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 (400 versus 330) on a single battery charge.
- 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 February 2005).
Arguments in favor of the Sony Cyber-shot DSC-RX100:
- More detail: Has more megapixels (20 vs 8MP), which boosts linear resolution by 58%.
- 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 (1.6 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1229k vs 115k dots).
- Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with an integrated lens, while the XT requires a separate lens.
- More compact: Is smaller (102x58mm vs 127x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the XT).
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 7 years and 3 months of technical progress since the XT launch.
If the number of relative strengths (bullet points above) is taken as a guide, the RX100 is the clear winner of the contest (14 : 7 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.
How about other alternatives? Do the specifications of the Canon XT and the Sony RX100 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the XT or the RX100 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
