Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M11 (Typ 2416) and the OM System OM-3? 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

An illustration of the physical size and weight of the Leica M11 and the OM System OM-3 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.

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

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the OM System OM-3 is notably larger (11 percent) than the Leica M11. However, the OM-3 is markedly lighter (23 percent) than the M11. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 (M11) and the Micro Four Thirds Lens Catalog (OM-3).

Concerning battery life, the M11 gets 700 shots out of its Leica BP-SCL7 battery, while the OM-3 can take 590 images on a single charge of its OM System BLX-1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The OM-3 was launched at a markedly lower price (by 78 percent) than the M11, 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 M11 features a full frame sensor and the OM System OM-3 a Four Thirds sensor. The sensor area in the OM-3 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 M11 has a native 3:2 aspect ratio, while the one in the OM-3 offers a 4:3 aspect.

With 60.3MP, the M11 offers a higher resolution than the OM-3 (20.2MP), but the M11 nevertheless has larger individual pixels (pixel pitch of 3.79μm versus 3.34μm for the OM-3) due to its larger sensor. However, the OM-3 is a much more recent model (by 3 years) than the M11, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Leica M11 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M11 for good quality output (200 dots per inch) amounts to 47.6 x 31.6 inches or 121 x 80.4 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.8 x 64.3 cm, and for excellent quality (300 dpi) 31.8 x 21.1 inches or 80.7 x 53.6 cm. The corresponding values for the OM System OM-3 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The OM-3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the M11, the OM-3 has the capacity to capture high quality composite images (80MP) 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 M11 (Typ 2416) has a native sensitivity range from ISO 64 to ISO 50000. The corresponding ISO settings for the OM System OM-3 are ISO 80 to ISO 25600, with the possibility to increase the ISO range to 80-102400.

In terms of underlying technology, the M11 is build around a BSI-CMOS sensor, while the OM-3 uses a Stacked BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. 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 OM-3 indeed provides for movie recording, while the M11 does not. The highest resolution format that the OM-3 can use is 4K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the OM-3 has an electronic viewfinder (2360k dots), while the M11 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 M11 has a higher magnification than the one of the OM-3 (0.73x vs 0.69x), 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 M11 and OM System OM-3 along with similar information for a selection of comparators.

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

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, both cameras under consideration feature an 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 Leica M11 and the OM System OM-3 both have 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 M11 and the OM-3 write their files to SDXC cards. The OM-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M11 only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

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 Leica M11 (Typ 2416) and OM System OM-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the M11 and the OM-3 are recent models that are part of the current product line-up. The M11 replaced the earlier Leica M10, while the OM-3 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and OM System websites.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica M11 and the OM System OM-3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Leica M11 (Typ 2416):

• More detail: Offers more megapixels (60.3 vs 20.2MP) with a 77% higher linear resolution.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.69x).
• More detailed LCD: Has a higher resolution rear screen (2333k vs 1640k dots).
• Longer lasting: Can take more shots (700 versus 590) on a single battery charge.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in January 2022).

Advantages of the OM System OM-3:

• High quality composites: Can combine several shots after pixel-shifting its sensor.
• Broader imaging potential: Can capture not only stills but also 4K/60p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More framing info: Has an electronic viewfinder that displays shooting data.
• 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.
• Faster burst: Shoots at higher frequency (6 vs 4.5 flaps/sec) to capture the decisive moment.
• Less heavy: Has a lower weight (by 144g or 22 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 (78 percent cheaper at launch).
• More modern: Reflects 3 years of technical progress since the M11 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the OM-3 emerges as the winner of the match-up (13 : 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 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 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 M11 and the OM-3 in practical situations. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
