Canon SX50 vs XSi

The Canon PowerShot SX50 HS and the Canon EOS Rebel XSi (labelled Canon 450D in some countries) are two digital cameras that were announced, respectively, in September 2012 and January 2008. The SX50 is a fixed lens compact, while the XSi is a DSLR. The cameras are based on a 1/2.3-inch (SX50) and an APS-C (XSi) sensor. The SX50 has a resolution of 12 megapixels, whereas the XSi provides 12.2 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 PowerShot SX50 HS and the Canon EOS Rebel XSi? 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.

Body comparison

An illustration of the physical size and weight of the Canon SX50 and the Canon XSi is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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 XSi is notably larger (18 percent) than the Canon SX50. In this context, it is worth noting that neither the SX50 nor the XSi are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX50 has a lens built in, whereas the XSi 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 XSi and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the SX50 gets 315 shots out of its Canon NB-10L battery, while the XSi can take 500 images on a single charge of its Canon LP-E5 power pack.

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

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. The SX50 was launched at a lower price than the XSi, 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.

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. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX50 features a 1/2.3-inch sensor and the Canon XSi an APS-C sensor. The sensor area in the XSi is 1075 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX50 has a native 4:3 aspect ratio, while the one in the XSi offers a 3:2 aspect.

In terms of chip-set technology, the SX50 uses a more advanced image processing engine (DIGIC 5) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

With 12.2MP, the XSi offers a higher resolution than the SX50 (12MP), but the XSi nevertheless has larger individual pixels (pixel pitch of 5.19μm versus 1.53μm for the SX50) due to its larger sensor. However, the SX50 is a much more recent model (by 4 years and 7 months) than the XSi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Canon PowerShot SX50 HS has a native sensitivity range from ISO 80 to ISO 6400. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the SX50 is build around a BSI-CMOS sensor, while the XSi uses a 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.

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"). Of the two cameras under consideration, the XSi offers substantially better image quality than the SX50 (overall score 14 points higher). The advantage is based on 1.6 bits higher color depth, 0.4 EV of lower dynamic range, and 2 stops in additional 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 SX50 indeed provides movie recording capabilities, while the XSi does not. The highest resolution format that the SX50 can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX50 has an electronic viewfinder (202k dots), while the XSi has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Canon SX50, the Canon XSi, and comparable cameras.

Both the SX50 and the XSi have been discontinued, but can regularly be found used on ebay. The XSi was replaced by the Canon T1i, while the SX50 was followed by the Canon SX60. Further information on the features and operation of the SX50 and XSi can be found, respectively, in the Canon SX50 Manual (free pdf) or the online Canon XSi Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon SX50 or the Canon XSi – 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 PowerShot SX50 HS:

• Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 3).
• Broader imaging potential: Can record not only still images but also 1080/24p movies.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Ready to shoot: Comes with a built-in lens, while the XSi requires a separate lens.
• More compact: Is smaller (123x87mm vs 129x98mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years and 7 months of technical progress since the XSi launch.

Advantages of the Canon EOS Rebel XSi:

• Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
• Better low-light sensitivity: Can shoot in dim conditions (2 stops ISO advantage).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (3.5 vs 2.2 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 315) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in January 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the SX50 emerges as the winner of the contest (11 : 9 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 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.

How about other alternatives? Do the specifications of the Canon SX50 and the Canon XSi place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 SX50 or the XSi. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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.
