Leica M9 vs Olympus E-M5 II

The Leica M9 and the Olympus OM-D E-M5 Mark II are two enthusiast cameras that were officially introduced, respectively, in September 2009 and February 2015. The M9 is a fixed lens compact, while the E-M5 II is a rangefinder-style mirrorless. The cameras are based on a full frame (M9) and a Four Thirds (E-M5 II) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Olympus 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 Leica M9 and the Olympus OM-D E-M5 Mark II? 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.

Body comparison: Leica M9 vs Olympus E-M5 II

The side-by-side display below illustrates the physical size and weight of the Leica M9 and the Olympus E-M5 II. 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.

Both cameras are available in two different colors (black, silver).

Compare M9 versus E-M5 II top
Comparison M9 or E-M5 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 II is notably smaller (5 percent) than the Leica M9. Moreover, the E-M5 II is markedly lighter (20 percent) than the M9. It is noteworthy in this context that the E-M5 II is splash and dust-proof, while the M9 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 (M9) and the Micro Four Thirds Lens Catalog (E-M5 II).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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-M5 II was launched at a markedly lower price (by 86 percent) than the M9, 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.

 

Sensor comparison: Leica M9 vs Olympus E-M5 II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 M9 features a full frame sensor and the Olympus E-M5 II a Four Thirds sensor. The sensor area in the E-M5 II 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 M9 has a native 3:2 aspect ratio, while the one in the E-M5 II offers a 4:3 aspect.

Leica M9 and Olympus E-M5 II sensor measures

With 18.1MP, the M9 offers a higher resolution than the E-M5 II (15.9MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 3.76μm for the E-M5 II) due to its larger sensor. However, the E-M5 II is a much more recent model (by 5 years and 4 months) than the M9, 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 M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inch or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inch or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inch or 44.1 x 29.4 cm. The corresponding values for the Olympus E-M5 II are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

Unlike the M9, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Olympus OM-D E-M5 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

M9 versus E-M5 II MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the E-M5 II has a markedly higher DXO score than the M9 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.8 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The E-M5 II indeed provides for movie recording, while the M9 does not. The highest resolution format that the E-M5 II can use is 1080/60p.

 

Feature comparison: Leica M9 vs Olympus E-M5 II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 II has an electronic viewfinder (2360k dots), while the M9 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-M5 II has a higher magnification than the one of the M9 (0.74x vs 0.68x), 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 Leica M9 and Olympus E-M5 II 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 E-M5 II has a touchscreen, while the M9 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-M5 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the M9 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-M5 II 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-M5 II 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 M9 and the E-M5 II write their files to SDXC cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the M9 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Leica M9 vs Olympus E-M5 II

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 M9 and Olympus OM-D E-M5 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M9 does not offer wifi capability.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the M9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The E-M5 II is a recent model that features in the current product line-up of Olympus. In contrast, the M9 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M9 was succeeded by the Leica M Typ 240. 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.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M5 II is the clear winner of the contest (24 : 5 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 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.

M9 05:24 E-M5 II

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 M9 or the E-M5 II 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.

Expert reviews: Leica M9 vs Olympus E-M5 II

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.

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

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
