Canon XSi vs Olympus TG-4
The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Olympus Tough TG-4 are two digital cameras that were announced, respectively, in January 2008 and April 2015. The XSi is a DSLR, while the TG-4 is a fixed lens compact. The cameras are based on an APS-C (XSi) and a 1/2.3-inch (TG-4) sensor. The Canon has a resolution of 12.2 megapixels, whereas the Olympus provides 15.9 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 XSi and the Olympus Tough TG-4? 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 XSi and the Olympus TG-4 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 TG-4 can be obtained in two different colors (black, red), 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 Olympus TG-4 is considerably smaller (42 percent) than the Canon XSi. It is noteworthy in this context that the TG-4 is splash and dust-proof, while the XSi does not feature any corresponding weather-sealing. More than that, the TG-4 is water-proof up to 15m and can, thus, be used for underwater photography.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TG-4 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 XSi gets 500 shots out of its LP-E5 battery, while the TG-4 can take 380 images on a single charge of its LI-92B power pack. The power pack in the TG-4 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 TG-4 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.
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. 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 XSi features an APS-C sensor and the Olympus TG-4 a 1/2.3-inch sensor. The sensor area in the TG-4 is 91 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the XSi has a native 3:2 aspect ratio, while the one in the TG-4 offers a 4:3 aspect.
Despite having a smaller sensor, the TG-4 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the 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 1.33μm versus 5.19μm for the XSi). However, it should be noted that the TG-4 is much more recent (by 7 years and 2 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.
The resolution advantage of the Olympus TG-4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TG-4 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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 EOS Rebel XSi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus Tough TG-4 are ISO 100 to ISO 6400 (no boost).
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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but can also record movies. The TG-4 indeed provides for movie recording, while the XSi does not. The highest resolution format that the TG-4 can use is 1080/30p.
Beyond 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 TG-4 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon XSi and Olympus TG-4 along with similar information for a selection of comparators.

The Olympus TG-4 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 XSi writes its imaging data to SDHC cards, while the TG-4 uses SDXC cards. The TG-4 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.
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 XSi and Olympus Tough TG-4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the XSi has a hotshoe, while the TG-4 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Travel and landscape photographers will find it useful that the TG-4 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the XSi and the TG-4 have been discontinued, but can regularly be found used on eBay. The XSi was replaced by the Canon T1i, while the TG-4 was followed by the Olympus TG-5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So what is the bottom line? Which of the two cameras – the Canon XSi or the Olympus TG-4 – 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 EOS Rebel XSi:
- 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.

If the number of relative strengths (bullet points above) is taken as a guide, the TG-4 is the clear winner of the contest (17 : 10 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 XSi and the Olympus TG-4 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the XSi or the TG-4 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 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
