Leica M10 vs Panasonic GH4

The Leica M10 (Typ 3656) and the Panasonic Lumix DMC-GH4 are two enthusiast cameras that were revealed to the public, respectively, in January 2017 and February 2014. The M10 is a fixed lens compact, while the GH4 is a rangefinder-style mirrorless. The cameras are based on a full frame (M10) and a Four Thirds (GH4) sensor. The Leica has a resolution of 23.8 megapixels, whereas the Panasonic 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 M10 (Typ 3656) and the Panasonic Lumix DMC-GH4? 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 M10 vs Panasonic GH4

The physical size and weight of the Leica M10 and the Panasonic GH4 are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.

The M10 can be obtained in two different colors (black, silver), while the GH4 is only available in black.

Compare M10 versus GH4 top
Comparison M10 or GH4 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH4 is notably larger (11 percent) than the Leica M10. However, the GH4 is markedly lighter (15 percent) than the M10. It is noteworthy in this context that the GH4 is splash and dust-proof, while the M10 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 Micro Four Thirds Lens Catalog (GH4).

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 GH4 was launched at a markedly lower price (by 77 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Leica M10 vs Panasonic GH4

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 M10 features a full frame sensor and the Panasonic GH4 a Four Thirds sensor. The sensor area in the GH4 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 GH4 offers a 4:3 aspect.

Leica M10 and Panasonic GH4 sensor measures

With 23.8MP, the M10 offers a higher resolution than the GH4 (15.9MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.76μm for the GH4) due to its larger sensor. Moreover, the M10 is a much more recent model (by 2 years and 11 months) than the GH4, 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 inch or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inch or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inch or 50.4 x 33.8 cm. The corresponding values for the Panasonic GH4 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.

The Leica M10 (Typ 3656) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Panasonic Lumix DMC-GH4 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

M10 versus GH4 MP

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"). Of the two cameras under review, the M10 provides substantially higher image quality than the GH4, with an overall score that is 12 points higher. This advantage is based on 1.2 bits higher color depth, 0.4 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GH4 indeed provides for movie recording, while the M10 does not. The highest resolution format that the GH4 can use is 4K/30p.

 

Feature comparison: Leica M10 vs Panasonic GH4

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH4 has an electronic viewfinder (2359k dots), while the M10 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 M10 has a higher magnification than the one of the GH4 (0.73x vs 0.67x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Leica M10, the Panasonic GH4, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH4 has a touchscreen, while the M10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GH4 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 M10 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 GH4 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 Leica M10 and the Panasonic GH4 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 M10 and the GH4 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Leica M10 vs Panasonic GH4

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 Panasonic Lumix DMC-GH4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Panasonic GH4 (unlike the M10) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The M10 is a recent model that features in the current product line-up of Leica. In contrast, the GH4 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GH4 was succeeded by the Panasonic GH5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Panasonic websites.


Review summary: Leica M10 vs Panasonic GH4

So how do things add up? Which of the two cameras – the Leica M10 or the Panasonic GH4 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Leica M10 (Typ 3656):

  • More detail: Offers more megapixels (23.8 vs 15.9MP) with a 24% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.67x).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Reflects 2 years and 11 months of technical progress since the GH4 launch.

ilogo

Reasons to prefer the Panasonic Lumix DMC-GH4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • 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 (12 vs 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Less heavy: Has a lower weight (by 100g or 15 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (500 versus 210) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the GH4 is the clear winner of the contest (17 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

M10 09:17 GH4

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M10 or the GH4. 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: Leica M10 vs Panasonic GH4

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 (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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
