Canon T7 vs Olympus E-3
The Canon EOS Rebel T7 (called Canon 2000D in some regions) and the Olympus E-3 are two digital cameras that were announced, respectively, in February 2018 and October 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T7) and a Four Thirds (E-3) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 10 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 T7 and the Olympus E-3? 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 T7 and the Olympus E-3. 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 dimensions 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 Olympus E-3 is notably larger (26 percent) than the Canon T7. Moreover, the E-3 is substantially heavier (84 percent) than the T7. It is noteworthy in this context that the E-3 is splash and dust-proof, while the T7 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 (T7) and the Four Thirds Lens Catalog (E-3).
Concerning battery life, the T7 gets 500 shots out of its Canon LP-E10 battery, while the E-3 can take 750 images on a single charge of its Olympus BLM-1 power pack.
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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T7 was launched at a markedly lower price (by 74 percent) than the E-3, which puts it into a different market segment. 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.
Sensor comparison
The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T7 features an APS-C sensor and the Olympus E-3 a Four Thirds sensor. The sensor area in the E-3 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 T7 has a native 3:2 aspect ratio, while the one in the E-3 offers a 4:3 aspect.
With 24MP, the T7 offers a higher resolution than the E-3 (10MP), but the T7 has smaller individual pixels (pixel pitch of 3.72μm versus 4.74μm for the E-3). However, the T7 is a much more recent model (by 10 years and 4 months) than the E-3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon T7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7 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 Olympus E-3 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.
The Canon EOS Rebel T7 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus E-3 are ISO 100 to ISO 3200 (no boost).
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.

Many modern cameras cannot only take still pictures, but also record videos. The T7 indeed provides movie recording capabilities, while the E-3 does not. The highest resolution format that the T7 can use is 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The T7 and the E-3 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the E-3 offers a wider field of view (100%) than the one in the T7 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-3 has a higher magnification (0.58x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T7, the Olympus E-3, and comparable cameras.

One feature that differentiates the E-3 and the T7 is in-body image stabilization (IBIS). The E-3 reduces the risk of handshake-induced blur with all attached lenses, while the T7 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The E-3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the T7 does not have a selfie-screen.The T7 writes its imaging data to SDXC cards, while the E-3 uses Compact Flash or xD Picture cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T7 only has one slot.
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 T7 and Olympus E-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7 offers wifi support, while the E-3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Olympus E-3 (unlike the T7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The T7 is a recent model that features in the current product line-up of Canon. In contrast, the E-3 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-3 was succeeded by the Olympus E-5. Further information on the features and operation of the T7 and E-3 can be found, respectively, in the Canon T7 Manual (free pdf) or the online Olympus E-3 Manual.
Review summary
So what is the bottom line? Is the Canon T7 better than the Olympus E-3 or vice versa? 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 T7 comes out slightly ahead of the E-3 (14 : 13 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 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 T7 and the Olympus E-3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 T7 or the E-3 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is why expert reviews are important. 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
