Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M9 and the Panasonic Lumix DMC-LX7? 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 M9 and the Panasonic LX7 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.

The M9 can be obtained in two different colors (black, silver), while the LX7 is also available in two color-versions, but different ones (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX7 is considerably smaller (32 percent) than the Leica M9. In this context, it is worth noting that neither the M9 nor the LX7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 has a lens built in, whereas the M9 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the M9 and their specifications in the Leica M Lens Catalog.

Concerning battery life, the M9 gets 550 shots out of its Leica BLI-312 battery, while the LX7 can take 330 images on a single charge of its Panasonic DMW-BCJ13 power pack.

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

Any camera decision will naturally be influenced heavily by the price. 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 LX7 was launched at a lower price than the M9, despite having a lens built in. 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M9 features a full frame sensor and the Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 95 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 4.65. The sensor in the M9 has a native 3:2 aspect ratio, while the one in the LX7 offers a 4:3 aspect. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

With 18.1MP, the M9 offers a higher resolution than the LX7 (10MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 2.05μm for the LX7) due to its larger sensor. However, the LX7 is a much more recent model (by 2 years and 10 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 inches or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inches or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.1 x 29.4 cm. The corresponding values for the Panasonic LX7 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 M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DMC-LX7 are ISO 80 to ISO 6400, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the M9 is build around a CCD sensor, while the LX7 uses a 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.

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"). Of the two cameras under review, the M9 provides substantially higher image quality than the LX7, with an overall score that is 19 points higher. This advantage is based on 1.8 bits higher color depth, and 2.6 stops in additional 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 are not only capable of taking still images, but can also record movies. The LX7 indeed provides for movie recording, while the M9 does not. The highest resolution format that the LX7 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the M9 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the LX7 relies on live view and the rear LCD for framing. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The table below summarizes some of the other core capabilities of the Leica M9 and Panasonic LX7 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 LX7 has one, while the M9 does not. While the built-in flash of the LX7 is not very powerful, it can at times be useful as a fill-in light.

The Panasonic LX7 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 LX7 write their files to SDXC cards.

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 M9 and Panasonic Lumix DMC-LX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the M9 and the LX7 have been discontinued, but can regularly be found used on ebay. The M9 was replaced by the Leica M Typ 240, while the LX7 was followed by the Panasonic LX10. Further information on the features and operation of the M9 and LX7 can be found, respectively, in the Leica M9 Manual (free pdf) or the online Panasonic LX7 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica M9 or the Panasonic LX7 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Leica M9:

• More detail: Offers more megapixels (18.1 vs 10MP) with a 37% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (19 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.8 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2.6 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (550 versus 330) 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 September 2009).

Arguments in favor of the Panasonic Lumix DMC-LX7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• 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 (920k vs 230k dots).
• Faster burst: Shoots at higher frequency (11 vs 2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the M9 necessitates an extra lens.
• More compact: Is smaller (111x68mm vs 139x80mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the M9).
• 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 at a lower price, despite coming with a built-in lens.
• More modern: Reflects 2 years and 10 months of technical progress since the M9 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the LX7 is the clear winner of the contest (14 : 10 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 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 M9 and the LX7 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

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

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
