Canon T7 vs Olympus E-300

The Canon EOS Rebel T7 (called Canon 2000D in some regions) and the Olympus Evolt E-300 are two digital cameras that were officially introduced, respectively, in February 2018 and September 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T7) and a Four Thirds (E-300) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 8 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 Evolt E-300? 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-300. 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 measures are rounded to the nearest millimeter.

Size Canon T7 vs Olympus E-300
Compare T7 versus E-300 top
Comparison T7 or E-300 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-300 is somewhat smaller (4 percent) than the Canon T7. However, the E-300 is markedly heavier (31 percent) than the T7. In this context, it is worth noting that neither the T7 nor the E-300 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 (T7) and the Four Thirds Lens Catalog (E-300).

Concerning battery life, the T7 gets 500 shots out of its LP-E10 battery, while the E-300 can take 750 images on a single charge of its BLM-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 T7 was launched at a markedly lower price (by 44 percent) than the E-300, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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-300 a Four Thirds sensor. The sensor area in the E-300 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-300 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon T7 and Olympus E-300 sensor measures

With 24MP, the T7 offers a higher resolution than the E-300 (8MP), but the T7 has smaller individual pixels (pixel pitch of 3.72μm versus 5.30μm for the E-300). However, the T7 is a much more recent model (by 13 years and 5 months) than the E-300, 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-300 are 16.3 x 12.2 inches or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inches or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inches or 27.6 x 20.7 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 Evolt E-300 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

T7 versus E-300 MP

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 cannot only take still pictures, but also record videos. The T7 indeed provides movie recording capabilities, while the E-300 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 range of features. The T7 and the E-300 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%), as well as the same magnification (0.50x). The following table reports on some other key feature differences and similarities of the Canon T7, the Olympus E-300, and comparable cameras.

It is notable that the T7 offers wifi support, while the E-300 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The T7 is a recent model that features in the current product line-up of Canon. In contrast, the E-300 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-300 was succeeded by the Olympus E-330. 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.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon T7 and the Olympus E-300? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS Rebel T7:

  • More detail: Offers more megapixels (24 vs 8MP) with a 77% 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 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).
  • Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 149g or 24 percent) and hence easier to carry around.
  • 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.
  • More affordable: Was introduced into a lower priced category (44 percent cheaper at launch).
  • More modern: Reflects 13 years and 5 months of technical progress since the E-300 launch.

ilogo

Reasons to prefer the Olympus Evolt E-300:

  • Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
  • 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 September 2004).

If the count of relative strengths (bullet points above) is taken as a measure, the T7 is the clear winner of the match-up (14 : 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.

T7 14:03 E-300

How about other alternatives? Do the specifications of the Canon T7 and the Olympus E-300 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 says little about, for example, the shooting experience and imaging performance of the T7 and the E-300 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.

Expert reviews

This is why hands-on reviews by experts 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
