Canon T7 vs Olympus E-1
The Canon EOS Rebel T7 (called Canon 2000D in some regions) and the Olympus E-1 are two digital cameras that were officially introduced, respectively, in February 2018 and June 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T7) and a Four Thirds (E-1) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 4.9 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 T7 and the Olympus E-1? 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 side-by-side display below illustrates the physical size and weight of the Canon T7 and the Olympus E-1. 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-1 is notably larger (13 percent) than the Canon T7. Moreover, the E-1 is substantially heavier (55 percent) than the T7. It is noteworthy in this context that the E-1 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-1).

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 T7 was launched at a markedly lower price (by 74 percent) than the E-1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon T7 features an APS-C sensor and the Olympus E-1 a Four Thirds sensor. The sensor area in the E-1 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-1 offers a 4:3 aspect.
With 24MP, the T7 offers a higher resolution than the E-1 (4.9MP), but the T7 has smaller individual pixels (pixel pitch of 3.72μm versus 6.78μm for the E-1). However, the T7 is a much more recent model (by 14 years and 8 months) than the E-1, 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 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-1 are 12.8 x 9.6 inch or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inch or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inch or 21.7 x 16.3 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-1 are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 also of capturing video footage. The T7 indeed provides movie recording capabilities, while the E-1 does not. The highest resolution format that the T7 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The T7 and the E-1 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-1 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. On the other hand, the viewfinder of the T7 has a higher magnification (0.50x vs 0.48x), 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 T7 and Olympus E-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T7 has one, while the E-1 does not. While the built-in flash of the T7 is not very powerful, it can at times be useful as a fill-in light.
The T7 writes its imaging data to SDXC cards, while the E-1 uses Compact Flash or xD Picture cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T7 only has one slot.
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-1 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-1 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-1 (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-1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-1 was succeeded by the Olympus E-3. 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 conclusions can be drawn? Is the Canon T7 better than the Olympus E-1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS Rebel T7:
- More detail: Offers more megapixels (24 vs 4.9MP) with a 125% higher linear resolution.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.50x vs 0.48x).
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 134k dots).
- More compact: Is smaller (129x101mm vs 141x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 263g or 36 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.

Advantages of the Olympus E-1:
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in June 2003).
If the count of individual advantages (bullet points above) is taken as a guide, the T7 is the clear winner of the match-up (16 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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-1 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the T7 and the E-1 in practical situations. 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
