Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX740 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

The side-by-side display below illustrates the physical size and weight of the Canon SX740 and the Canon XSi. 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 SX740 can be obtained in two different colors (black, silver), while the XSi 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 Canon XSi is considerably larger (80 percent) than the Canon SX740. In this context, it is worth noting that neither the SX740 nor the XSi are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX740 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 SX740 gets 265 shots out of its Canon NB-13L battery, while the XSi can take 500 images on a single charge of its Canon LP-E5 power pack. The power pack in the SX740 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 SX740 was launched at a lower price than the XSi, 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.

Sensor comparison

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 SX740 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 SX740 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 SX740 uses a more advanced image processing engine (DIGIC 8) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the Canon SX740 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the Canon XSi. 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 1.18μm versus 5.19μm for the XSi). However, it should be noted that the SX740 is much more recent (by 10 years and 6 months) than the XSi, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX740 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX740 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX740 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Canon XSi are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.

The Canon PowerShot SX740 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the SX740 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The SX740 indeed provides movie recording capabilities, while the XSi does not. The highest resolution format that the SX740 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the XSi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX740 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 SX740, the Canon XSi, and comparable cameras.

The Canon SX740 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The SX740 writes its imaging data to SDXC cards, while the XSi uses SDHC cards. The SX740 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the XSi cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 PowerShot SX740 HS and Canon EOS Rebel XSi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX740 offers wifi support, while the XSi does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the XSi has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the XSi was succeeded by the Canon T1i. Further information on the features and operation of the SX740 and XSi can be found, respectively, in the Canon SX740 Manual (free pdf) or the online Canon XSi Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon SX740 or the Canon XSi – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX740 HS:

• More detail: Offers more megapixels (20.2 vs 12.2MP) with a 26% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 3).
• Broader imaging potential: Can record not only still images but also 4K/30p movies.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 3.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the XSi requires a separate lens.
• More compact: Is smaller (110x64mm vs 129x98mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the XSi).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 10 years and 6 months of technical progress since the XSi launch.

Advantages of the Canon EOS Rebel XSi:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 265) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in January 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the SX740 is the clear winner of the match-up (19 : 11 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.

How about other alternatives? Do the specifications of the Canon SX740 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX740 or the XSi. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
