Canon XTi vs Olympus E-M1
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Olympus OM-D E-M1 are two digital cameras that were officially introduced, respectively, in August 2006 and September 2013. The XTi is a DSLR, while the E-M1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (XTi) and a Four Thirds (E-M1) sensor. The Canon has a resolution of 10.1 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 XTi and the Olympus OM-D E-M1? 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 XTi and the Olympus E-M1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The E-M1 can be obtained in two different colors (black, silver), while the XTi 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 E-M1 is notably larger (15 percent) than the Canon XTi. However, the E-M1 is markedly lighter (11 percent) than the XTi. It is noteworthy in this context that the E-M1 is splash and dust-proof, while the XTi does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (XTi) and the Micro Four Thirds Lens Catalog (E-M1). Mirrorless cameras, such as the E-M1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the XTi gets 370 shots out of its Canon NB-2LH battery, while the E-M1 can take 350 images on a single charge of its Olympus BLN-1 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 XTi was launched at a markedly lower price (by 43 percent) than the E-M1, which puts it into a different market segment. 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 size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Olympus E-M1 a Four Thirds sensor. The sensor area in the E-M1 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the XTi has a native 3:2 aspect ratio, while the one in the E-M1 offers a 4:3 aspect.
Despite having a smaller sensor, the E-M1 offers a higher resolution of 15.9 megapixels, compared with 10.1 MP of the XTi. 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 3.76μm versus 5.71μm for the XTi). However, it should be noted that the E-M1 is much more recent (by 7 years) than the XTi, 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 E-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Olympus E-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M1 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 XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The E-M1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus OM-D E-M1 are ISO 200 to ISO 25600, 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.
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 E-M1 offers substantially better image quality than the XTi (overall score 11 points higher). The advantage is based on 0.9 bits higher color depth, 1.7 EV in additional dynamic range, and 0.2 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 are not only capable of taking still images, but can also record movies. The E-M1 indeed provides for movie recording, while the XTi does not. The highest resolution format that the E-M1 can use is 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M1 has an electronic viewfinder (2360k dots), while the XTi 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 viewfinder in the E-M1 offers a wider field of view (100%) than the one in the XTi (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M1 has a higher magnification (0.74x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon XTi and Olympus E-M1 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The XTi has one, while the E-M1 does not. While the built-in flash of the XTi is not very powerful, it can at times be useful as a fill-in light.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Olympus E-M1 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 XTi writes its imaging data to Compact Flash cards, while the E-M1 uses SDXC 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 EOS Rebel XTi and Olympus OM-D E-M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the XTi does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-M1 (unlike the XTi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the XTi and the E-M1 have been discontinued, but can regularly be found used on ebay. The XTi was replaced by the Canon Xsi, while the E-M1 was followed by the Olympus E-M1 II. Further information on the features and operation of the XTi and E-M1 can be found, respectively, in the Canon XTi Manual (free pdf) or the online Olympus E-M1 Manual.
Review summary
So what conclusions can be drawn? Is there a clear favorite between the Canon XTi and the Olympus E-M1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M1 is the clear winner of the contest (24 : 6 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 XTi and the Olympus E-M1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the XTi or the E-M1. 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
