Olympus E-300 vs E-M10
The Olympus Evolt E-300 and the Olympus OM-D E-M10 are two digital cameras that were officially introduced, respectively, in September 2004 and January 2014. The E-300 is a DSLR, while the E-M10 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The E-300 has a resolution of 8 megapixels, whereas the E-M10 provides 15.9 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 Olympus Evolt E-300 and the Olympus OM-D E-M10? 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 Olympus E-300 and the Olympus E-M10 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 size dimensions are rounded to the nearest millimeter.
The E-M10 can be obtained in two different colors (black, silver), 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-M10 is notably smaller (22 percent) than the Olympus E-300. Moreover, the E-M10 is substantially lighter (37 percent) than the E-300. In this context, it is worth noting that neither the E-300 nor the E-M10 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-300) and the Micro Four Thirds Lens Catalog (E-M10). Mirrorless cameras, such as the E-M10, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will naturally be influenced heavily by the price. 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 E-M10 was launched at a somewhat lower price (by 13 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, the E-M10 uses a more advanced image processing engine (TruePic VII) than the E-300 (TruePic), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the E-M10 offers a higher resolution of 15.9 megapixels, compared with 8 MP of the E-300. This megapixels advantage translates into a 41 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 5.30μm for the E-300). However, it should be noted that the E-M10 is much more recent (by 9 years and 4 months) than the E-300, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Olympus E-M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 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 Olympus Evolt E-300 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Olympus OM-D E-M10 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The E-M10 indeed provides for movie recording, while the E-300 does not. The highest resolution format that the E-M10 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 has an electronic viewfinder (1440k dots), while the E-300 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the E-M10 offers a wider field of view (100%) than the one in the E-300 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M10 has a higher magnification (0.58x vs 0.5x), 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 Olympus E-300 and Olympus E-M10 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 E-M10 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 Olympus E-M10 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The E-300 writes its imaging data to Compact Flash or xD Picture cards, while the E-M10 uses SDXC cards. The E-300 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M10 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 Olympus Evolt E-300 and Olympus OM-D E-M10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-300 does not provide wifi capability.
Both the E-300 and the E-M10 have been discontinued, but can regularly be found used on eBay. The E-300 was replaced by the Olympus E-330, while the E-M10 was followed by the Olympus E-M10 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.
So what is the bottom line? Is the Olympus E-300 better than the Olympus E-M10 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus Evolt E-300:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 is the clear winner of the contest (20 : 5 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 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 Olympus E-300 and the Olympus E-M10 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains incomplete and does no justice, for example, to the way the E-300 or the E-M10 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
