Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-3 and the Olympus E-M10 III. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The E-M10 III can be obtained in two different colors (black, silver), while the E-3 is only available in black.

Compare E-3 versus E-M10 III top
Comparison E-3 or E-M10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 III is considerably smaller (38 percent) than the Olympus E-3. Moreover, the E-M10 III is substantially lighter (53 percent) than the E-3. It is worth mentioning in this context that the E-3 is splash and dust resistant, while the E-M10 III does not feature any corresponding weather-sealing.

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-3) and the Micro Four Thirds Lens Catalog (E-M10 III). Mirrorless cameras, such as the E-M10 III, 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.

Concerning battery life, the E-3 gets 750 shots out of its Olympus BLM-1 battery, while the E-M10 III can take 330 images on a single charge of its Olympus BLS-50 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Note: 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 E-M10 III was launched at a markedly lower price (by 62 percent) than the E-3, 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. 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 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 III uses a more advanced image processing engine (TruePic VIII) than the E-3 (TruePic III), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-3 and Olympus E-M10 III sensor measures

While the two cameras under review share the same sensor size, the E-M10 III offers a higher resolution of 15.9 megapixels, compared with 10 MP of the E-3. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 III has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.74μm for the E-3). However, it should be noted that the E-M10 III is much more recent (by 9 years and 10 months) than the E-3, 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 III 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 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 III 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-3 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-3 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Olympus OM-D E-M10 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-3 versus E-M10 III 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 III has an electronic viewfinder (2360k dots), while the E-3 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the E-M10 III has a higher magnification than the one of the E-3 (0.62x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-3 and Olympus E-M10 III in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the E-3, but is missing on the E-M10 III is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The E-3 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-M10 III does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M10 III is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M10 III 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-3 writes its imaging data to Compact Flash or xD Picture cards, while the E-M10 III uses SDXC cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M10 III 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 Olympus E-3 and Olympus OM-D E-M10 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-3 does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-3 (unlike the E-M10 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-3 and the E-M10 III have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the E-M10 III was followed by the Olympus E-M10 IV. Further information on the features and operation of the E-3 and E-M10 III can be found, respectively, in the Olympus E-3 Manual (free pdf) or the online Olympus E-M10 III Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-3 or the Olympus E-M10 III – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Olympus E-3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Longer lasting: Can take more shots (750 versus 330) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in October 2007).


Reasons to prefer the Olympus OM-D E-M10 Mark III:

  • More detail: Has more megapixels (15.9 vs 10MP), which boosts linear resolution by 26%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better jpgs: Has a more modern image processing engine (TruePic VIII vs TruePic III).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.58x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (8.6 vs 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (122x84mm vs 142x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 466g or 53 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (62 percent cheaper at launch).
  • More modern: Reflects 9 years and 10 months of technical progress since the E-3 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 III is the clear winner of the contest (18 : 11 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.

E-3 11:18 E-M10 III

How about other alternatives? Do the specifications of the Olympus E-3 and the Olympus E-M10 III 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-3 or the E-M10 III perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
