Leica M8 vs Panasonic G90

The Leica M8 and the Panasonic Lumix DC-G90 (labelled Panasonic G95 in some countries) are two digital cameras that were officially introduced, respectively, in September 2006 and April 2019. The M8 is a rangefinder-focusing mirrorless, while the G90 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (M8) and a Four Thirds (G90) sensor. The Leica has a resolution of 10.4 megapixels, whereas the Panasonic provides 20.2 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 M8 and the Panasonic Lumix DC-G90? 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

The side-by-side display below illustrates the physical size and weight of the Leica M8 and the Panasonic G90. 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.

The M8 can be obtained in two different colors (black, silver), while the G90 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 Panasonic G90 is notably larger (10 percent) than the Leica M8. However, the G90 is markedly lighter (9 percent) than the M8. It is noteworthy in this context that the G90 is splash and dust-proof, while the M8 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 (M8) and the Micro Four Thirds Lens Catalog (G90).

Concerning battery life, the M8 gets 550 shots out of its Leica BLI-312 battery, while the G90 can take 290 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the G90 can be charged via the USB port, 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 G90 was launched at a markedly lower price (by 82 percent) than the M8, 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

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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M8 features an APS-H sensor and the Panasonic G90 a Four Thirds sensor. The sensor area in the G90 is 54 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the M8 has a native 3:2 aspect ratio, while the one in the G90 offers a 4:3 aspect.

Despite having a smaller sensor, the G90 offers a higher resolution of 20.2 megapixels, compared with 10.4 MP of the M8. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 6.84μm for the M8). However, it should be noted that the G90 is much more recent (by 12 years and 6 months) than the M8, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 Panasonic G90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G90 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Leica M8 are 19.7 x 13.2 inches or 50 x 33.4 cm for good quality, 15.7 x 10.5 inches or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inches or 33.3 x 22.3 cm for excellent quality prints.

The Leica M8 has a native sensitivity range from ISO 160 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DC-G90 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the M8 is build around a CCD sensor, while the G90 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 also of capturing video footage. The G90 indeed provides for movie recording, while the M8 does not. The highest resolution format that the G90 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G90 has an electronic viewfinder (2360k dots), while the M8 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 adjacent table lists some of the other core features of the Leica M8 and Panasonic G90 along with similar information for a selection of comparators.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G90 has a touchscreen, while the M8 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 G90 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 Panasonic G90 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 M8 and the G90 write their files to SDXC cards. The G90 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the M8 cannot take advantage of Ultra High Speed SD 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 M8 and Panasonic Lumix DC-G90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G90 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M8 does not provide wifi capability.

Both the M8 and the G90 have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the G90 does not have a direct successor. Further information on the features and operation of the M8 and G90 can be found, respectively, in the Leica M8 Manual (free pdf) or the online Panasonic G90 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica M8 and the Panasonic G90? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica M8:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.

• Longer lasting: Can take more shots (550 versus 290) 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 2006).

Advantages of the Panasonic Lumix DC-G90:

• More detail: Has more megapixels (20.2 vs 10.4MP), which boosts linear resolution by 37%.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• 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 (1240k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

• Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
• More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
• More modern: Reflects 12 years and 6 months of technical progress since the M8 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G90 is the clear winner of the contest (20 : 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.

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 M8 or the G90 perform in practice. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
