Canon XT vs Sony RX1
The Canon EOS Rebel XT (called Canon 350D in some regions) and the Sony Cyber-shot DSC-RX1 are two digital cameras that were announced, respectively, in February 2005 and September 2012. The XT is a DSLR, while the RX1 is a fixed lens compact. The cameras are based on an APS-C (XT) and a full frame (RX1) sensor. The Canon has a resolution of 8 megapixels, whereas the Sony provides 24 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-RX1? 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 XT and the Sony RX1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The XT can be obtained in two different colors (black, silver), while the RX1 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 RX1 is considerably smaller (38 percent) than the Canon XT. In this context, it is worth noting that neither the XT nor the RX1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1 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 RX1 can take 270 images on a single charge of its NP-BX1 power pack. The power pack in the RX1 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.

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. 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.
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 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 RX1 a full frame sensor. The sensor area in the RX1 is 159 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the RX1 offers a higher resolution than the XT (8MP), but the RX1 has smaller individual pixels (pixel pitch of 5.96μm versus 6.41μm for the XT). Yet, the RX1 is a much more recent model (by 7 years and 6 months) than the XT, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony RX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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-RX1 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 RX1 offers substantially better image quality than the XT (overall score 33 points higher). The advantage is based on 3.3 bits higher color depth, 3.5 EV in additional dynamic range, and 2 stops in additional 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 cannot only take still pictures, but also record videos. The RX1 indeed provides for movie recording, while the XT does not. The highest resolution format that the RX1 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the XT has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX1 relies on live view and the rear LCD for framing. That said, the RX1 can be equipped with an optional viewfinder – the FDA-EV1MK. The following table reports on some other key feature differences and similarities of the Canon XT, the Sony RX1, and comparable cameras.

The XT writes its imaging data to Compact Flash cards, while the RX1 uses SDXC or Memory Stick PRO Duo 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 XT and Sony Cyber-shot DSC-RX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XT and the RX1 have been discontinued, but can regularly be found used on eBay. The XT was replaced by the Canon Xti, while the RX1 was followed by the Sony RX1R. 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? Which of the two cameras – the Canon XT or the Sony RX1 – 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.
Arguments in favor of the Canon EOS Rebel XT:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (400 versus 270) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in February 2005).
Reasons to prefer the Sony Cyber-shot DSC-RX1:
- More detail: Has more megapixels (24 vs 8MP), which boosts linear resolution by 74%.
- Better image quality: Scores substantially higher (33 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.3 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3.5 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (2 stops ISO advantage).
- 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 (5 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 (113x65mm 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.
- More modern: Reflects 7 years and 6 months of technical progress since the XT launch.
If the count of relative strengths (bullet points above) is taken as a measure, the RX1 is the clear winner of the contest (14 : 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 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 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 RX1 perform in practice. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
