Canon T100 vs Olympus E-300

The Canon EOS Rebel T100 (called Canon 4000D 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 (T100) and a Four Thirds (E-300) sensor. The Canon has a resolution of 17.9 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 T100 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

An illustration of the physical size and weight of the Canon T100 and the Olympus E-300 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon T100 vs Olympus E-300
Compare T100 versus E-300 top
Comparison T100 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 notably smaller (5 percent) than the Canon T100. However, the E-300 is substantially heavier (43 percent) than the T100. In this context, it is worth noting that neither the T100 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 (T100) and the Four Thirds Lens Catalog (E-300).

Concerning battery life, the T100 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The T100 was launched at a markedly lower price (by 50 percent) than the E-300, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 T100 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 T100 has a native 3:2 aspect ratio, while the one in the E-300 offers a 4:3 aspect.

Canon T100 and Olympus E-300 sensor measures

With 17.9MP, the T100 offers a higher resolution than the E-300 (8MP), but the T100 has smaller individual pixels (pixel pitch of 4.31μm versus 5.30μm for the E-300). However, the T100 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 T100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T100 for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 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 T100 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.

In terms of underlying technology, the T100 is build around a CMOS sensor, while the E-300 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

T100 versus E-300 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 also of capturing video footage. The T100 indeed provides movie recording capabilities, while the E-300 does not. The highest resolution format that the T100 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The T100 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 adjacent table lists some of the other core features of the Canon T100 and Olympus E-300 along with similar information for a selection of comparators.

The T100 writes its imaging data to SDXC cards, while the E-300 uses Compact Flash or xD Picture cards. The E-300 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T100 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 T100 and Olympus Evolt E-300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T100 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 T100 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 features and operation of the T100 and E-300 can be found, respectively, in the Canon T100 Manual (free pdf) or the online Olympus E-300 Manual.

Review summary

So what conclusions can be drawn? Is the Canon T100 better than the Olympus E-300 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Canon EOS Rebel T100:

  • More detail: Offers more megapixels (17.9 vs 8MP) with a 53% 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 (2.7" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k 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 188g or 30 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 (50 percent cheaper at launch).
  • More modern: Reflects 13 years and 5 months of technical progress since the E-300 launch.

ilogo

Arguments in favor of 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 individual advantages (bullet points above) is taken as a guide, the T100 is the clear winner of the match-up (14 : 3 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 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.

T100 14:03 E-300

How about other alternatives? Do the specifications of the Canon T100 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 T100 and the E-300 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 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.
