Leica M10-P vs Olympus E-P3
The Leica M10-P and the Olympus PEN E-P3 are two enthusiast cameras that were officially introduced, respectively, in August 2018 and June 2011. The M10-P is a fixed lens compact, while the E-P3 is a rangefinder-style mirrorless. The cameras are based on a full frame (M10-P) and a Four Thirds (E-P3) sensor. The Leica has a resolution of 23.8 megapixels, whereas the Olympus provides 12.2 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 Leica M10-P and the Olympus PEN E-P3? 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 Leica M10-P and the Olympus E-P3. 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 measures are rounded to the nearest millimeter.
The M10-P can be obtained in two different colors (black, silver), while the E-P3 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P3 is notably smaller (24 percent) than the Leica M10-P. Moreover, the E-P3 is substantially lighter (44 percent) than the M10-P. It is worth mentioning in this context that the M10-P is splash and dust resistant, while the E-P3 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. 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 Leica M Lens Catalog (M10-P) and the Micro Four Thirds Lens Catalog (E-P3).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-P3 was launched at a markedly lower price (by 90 percent) than the M10-P, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Leica M10-P features a full frame sensor and the Olympus E-P3 a Four Thirds sensor. The sensor area in the E-P3 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the M10-P has a native 3:2 aspect ratio, while the one in the E-P3 offers a 4:3 aspect.
With 23.8MP, the M10-P offers a higher resolution than the E-P3 (12.2MP), but the M10-P nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.29μm for the E-P3) due to its larger sensor. Moreover, the M10-P is a much more recent model (by 7 years and 1 month) than the E-P3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the M10-P has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica M10-P implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-P for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 cm. The corresponding values for the Olympus E-P3 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Leica M10-P has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Olympus PEN E-P3 are ISO 200 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 are not only capable of taking still images, but can also record movies. The E-P3 indeed provides for movie recording, while the M10-P does not. The highest resolution format that the E-P3 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the M10-P has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The table below summarizes some of the other core capabilities of the Leica M10-P and Olympus E-P3 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-P3 has one, while the M10-P does not. While the built-in flash of the E-P3 is not very powerful, it can at times be useful as a fill-in light.
The Leica M10-P 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.
Concerning the storage of imaging data, both the M10-P and the E-P3 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Leica M10-P and Olympus PEN E-P3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10-P offers wifi support, while the E-P3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The M10-P is a recent model that features in the current product line-up of Leica. In contrast, the E-P3 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-P3 was succeeded by the Olympus E-P5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Olympus websites.
So how do things add up? Is the Leica M10-P better than the Olympus E-P3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Leica M10-P:
- More detail: Offers more megapixels (23.8 vs 12.2MP) with a 42% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- 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.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 614k dots).
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 7 years and 1 month of technical progress since the E-P3 launch.
Advantages of the Olympus PEN E-P3:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- More compact: Is smaller (122x69mm vs 139x80mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 291g or 44 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (330 versus 210) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in June 2011).
If the count of individual advantages (bullet points above) is taken as a guide, the M10-P is the clear winner of the match-up (14 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the M10-P or the E-P3 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
