Canon T7i vs Olympus E-330
The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Olympus Evolt E-330 are two digital cameras that were announced, respectively, in February 2017 and January 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T7i) and a Four Thirds (E-330) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 7.4 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 T7i and the Olympus Evolt E-330? 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.
An illustration of the physical size and weight of the Canon T7i and the Olympus E-330 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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-330 is notably smaller (7 percent) than the Canon T7i. However, the E-330 is markedly heavier (20 percent) than the T7i. In this context, it is worth noting that neither the T7i nor the E-330 are weather-sealed.
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 (T7i) and the Four Thirds Lens Catalog (E-330).
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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T7i was launched at a somewhat lower price (by 25 percent) than the E-330, which makes it more attractive for photographers on a tight budget. 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. 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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T7i features an APS-C sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 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 T7i has a native 3:2 aspect ratio, while the one in the E-330 offers a 4:3 aspect.
With 24MP, the T7i offers a higher resolution than the E-330 (7.4MP), but the T7i has smaller individual pixels (pixel pitch of 3.72μm versus 5.51μm for the E-330). However, the T7i is a much more recent model (by 11 years) than the E-330, 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 T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i 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-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.
The T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T7i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.
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"). 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 T7i indeed provides movie recording capabilities, while the E-330 does not. The highest resolution format that the T7i can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The T7i and the E-330 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the T7i has a higher magnification than the one of the E-330 (0.51x vs 0.47x), 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 T7i and Olympus E-330 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T7i has a touchscreen, while the E-330 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T7i 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-330 does not have a selfie-screen.
The T7i writes its imaging data to SDXC cards, while the E-330 uses Compact Flash or xD Picture cards. The E-330 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T7i 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 T7i and Olympus Evolt E-330 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i offers wifi support, while the E-330 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the T7i and the E-330 have been discontinued, but can regularly be found used on eBay. The T7i was replaced by the Canon T8i, while the E-330 does not have a direct successor. 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 T7i better than the Olympus E-330 or vice versa? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been around for much longer (launched in January 2006).
If the number of relative strengths (bullet points above) is taken as a guide, the T7i is the clear winner of the match-up (20 : 3 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 T7i and the Olympus E-330 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 incomplete and does no justice, for example, to the way the T7i or the E-330 perform in practice. 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 hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
