Canon 750D vs Olympus E-1
The Canon EOS 750D (called Canon T6i in some regions) and the Olympus E-1 are two digital cameras that were announced, respectively, in February 2015 and June 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (750D) 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 750D 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 physical size and weight of the Canon 750D and the Olympus E-1 are illustrated in the side-by-side display below. 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 size 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 (10 percent) than the Canon 750D. Moreover, the E-1 is markedly heavier (33 percent) than the 750D. It is noteworthy in this context that the E-1 is splash and dust-proof, while the 750D 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 (750D) and the Four Thirds Lens Catalog (E-1).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. 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 750D was launched at a markedly lower price (by 56 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.
The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 750D 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 750D has a native 3:2 aspect ratio, while the one in the E-1 offers a 4:3 aspect.
With 24MP, the 750D offers a higher resolution than the E-1 (4.9MP), but the 750D has smaller individual pixels (pixel pitch of 3.72μm versus 6.78μm for the E-1). However, the 750D is a much more recent model (by 11 years and 7 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 750D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 750D 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 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 750D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The 750D indeed provides movie recording capabilities, while the E-1 does not. The highest resolution format that the 750D can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 750D 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 750D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 750D has a higher magnification (0.51x 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 750D 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 750D has one, while the E-1 does not. While the built-in flash of the 750D is not very powerful, it can at times be useful as a fill-in light.The 750D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-1 does not have a selfie-screen.
The 750D 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 750D 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 750D 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 750D 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 750D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 750D and the E-1 have been discontinued, but can regularly be found used on eBay. The E-1 was replaced by the Olympus E-3, while the 750D was followed by the Canon 800D. 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 750D better than the Olympus E-1 or vice versa? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the 750D is the clear winner of the match-up (20 : 7 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 750D 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 750D or the E-1. 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.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
