Canon M3 vs Olympus E-300
The Canon EOS M3 and the Olympus Evolt E-300 are two digital cameras that were revealed to the public, respectively, in February 2015 and September 2004. The M3 is a mirrorless interchangeable lens camera, while the E-300 is a DSLR. The cameras are based on an APS-C (M3) 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 M3 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.
The side-by-side display below illustrates the physical size and weight of the Canon M3 and the Olympus E-300. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The M3 can be obtained in two different colors (black, white), while the E-300 is only available in black.
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 considerably larger (66 percent) than the Canon M3. Moreover, the E-300 is substantially heavier (70 percent) than the M3. In this context, it is worth noting that neither the M3 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 M3 was launched at a somewhat lower price (by 15 percent) than the E-300, which makes it more attractive for photographers on a tight budget. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 M3 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 M3 has a native 3:2 aspect ratio, while the one in the E-300 offers a 4:3 aspect.
With 24MP, the M3 offers a higher resolution than the E-300 (8MP), but the M3 has smaller individual pixels (pixel pitch of 3.72μm versus 5.30μm for the E-300). However, the M3 is a much more recent model (by 10 years and 4 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 M3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M3 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 M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M3 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 Evolt E-300 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.
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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The M3 indeed provides movie recording capabilities, while the E-300 does not. The highest resolution format that the M3 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-300 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M3 relies on live view and the rear LCD for framing. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Canon M3 and Olympus E-300 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M3 has a touchscreen, while the E-300 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M3 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-300 does not have a selfie-screen.
The M3 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 M3 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 M3 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 M3 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.
Both the M3 and the E-300 have been discontinued, but can regularly be found used on eBay. The E-300 was replaced by the Olympus E-330, while the M3 was followed by the Canon M6. 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 is the bottom line? Is there a clear favorite between the Canon M3 and the Olympus E-300? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the M3 is the clear winner of the match-up (20 : 4 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the M3 or the E-300 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.

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. 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.
