Leica M10 vs Olympus E-520
The Leica M10 (Typ 3656) and the Olympus E-520 are two digital cameras that were announced, respectively, in January 2017 and May 2008. The M10 is a rangefinder-style mirrorless camera, while the E-520 is a DSLR. The cameras are based on a full frame (M10) and a Four Thirds (E-520) sensor. The Leica has a resolution of 23.8 megapixels, whereas the Olympus provides 10 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 (Typ 3656) and the Olympus E-520? 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 and the Olympus E-520. 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.
The M10 can be obtained in two different colors (black, silver), while the E-520 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-520 is notably larger (13 percent) than the Leica M10. However, the E-520 is markedly lighter (19 percent) than the M10. It is worth mentioning in this context that the M10 is splash and dust resistant, while the E-520 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) and the Four Thirds Lens Catalog (E-520).

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-520 was launched at a markedly lower price (by 89 percent) than the M10, 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.
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Leica M10 features a full frame sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 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 has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 23.8MP, the M10 offers a higher resolution than the E-520 (10MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.74μm for the E-520) due to its larger sensor. Moreover, the M10 is a much more recent model (by 8 years and 8 months) than the E-520, 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 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 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-520 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 Leica M10 (Typ 3656) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).
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"). Of the two cameras under review, the M10 provides substantially higher image quality than the E-520, with an overall score that is 31 points higher. This advantage is based on 3 bits higher color depth, 2.8 EV in additional dynamic range, and 2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Apart from body and sensor, cameras can and do differ across a variety of features. The M10 and the E-520 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 viewfinder in the M10 offers a wider field of view (100%) than the one in the E-520 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the M10 has a higher magnification (0.73x vs 0.46x), 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 Leica M10 and Olympus E-520 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-520 has one, while the M10 does not. While the built-in flash of the E-520 is not very powerful, it can at times be useful as a fill-in light.
The Leica 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 M10 writes its imaging data to SDXC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 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 Leica M10 (Typ 3656) and Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10 offers wifi support, while the E-520 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The M10 is a recent model that features in the current product line-up of Leica. In contrast, the E-520 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-520 from Olympus. 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 there a clear favorite between the Leica M10 and the Olympus E-520? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Leica M10 (Typ 3656):
- More detail: Offers more megapixels (23.8 vs 10MP) with a 57% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (31 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (3 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.8 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.46x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 215k dots).
- Faster burst: Shoots at higher frequency (5 vs 3.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (139x80mm vs 136x92mm) and thus needs less room in the bag.
- 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 8 years and 8 months of technical progress since the E-520 launch.
Arguments in favor of the Olympus E-520:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Less heavy: Has a lower weight (by 125g or 19 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (750 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.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in May 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the M10 is the clear winner of the match-up (17 : 8 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the M10 and the E-520 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.
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 (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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
