Leica M8 vs Sony A7 III

The Leica M8 and the Sony Alpha A7 III are two enthusiast cameras that were officially introduced, respectively, in September 2006 and February 2018. The M8 is a fixed lens compact, while the A7 III is a rangefinder-style mirrorless. The cameras are based on an APS-H (M8) and a full frame (A7 III) sensor. The Leica has a resolution of 10.4 megapixels, whereas the Sony provides 24 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 Sony Alpha A7 III? 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 Sony A7 III. 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 M8 can be obtained in two different colors (black, silver), while the A7 III is only available in black.

Compare M8 versus A7 III top
Comparison M8 or A7 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 III is notably larger (10 percent) than the Leica M8. Moreover, the A7 III is markedly heavier (10 percent) than the M8. It is noteworthy in this context that the A7 III 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 Sony FE Lens Catalog (A7 III).

The power pack in the A7 III can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 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 A7 III was launched at a markedly lower price (by 64 percent) than the M8, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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. 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 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 Sony A7 III a full frame sensor. The sensor area in the A7 III is 74 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica M8 and Sony A7 III sensor measures

With 24MP, the A7 III offers a higher resolution than the M8 (10.4MP), but the A7 III has smaller individual pixels (pixel pitch of 5.94μm versus 6.84μm for the M8). Yet, the A7 III is a much more recent model (by 11 years and 5 months) than the M8, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 Sony A7 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 III for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Leica M8 are 19.7 x 13.2 inch or 50 x 33.4 cm for good quality, 15.7 x 10.5 inch or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inch or 33.3 x 22.3 cm for excellent quality prints.

The A7 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica M8 has a native sensitivity range from ISO 160 to ISO 2500. The corresponding ISO settings for the Sony Alpha A7 III are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

M8 versus A7 III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A7 III offers substantially better image quality than the M8 (overall score 37 points higher). The advantage is based on 3.9 bits higher color depth, 3.4 EV in additional dynamic range, and 2.5 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 A7 III indeed provides for movie recording, while the M8 does not. The highest resolution format that the A7 III 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 A7 III has an electronic viewfinder (2359k 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A7 III 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 A7 III 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 Sony A7 III 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.

The M8 writes its imaging data to SDXC cards, while the A7 III uses SDXC or Memory Stick PRO Duo cards. The A7 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the M8 only has one slot. The A7 III supports UHS-II cards on its first slot and UHS-I on its second one, 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 Sony Alpha A7 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 III 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 offer wifi capability.

The A7 III is a recent model that features in the current product line-up of Sony. In contrast, the M8 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M8 was succeeded by the Leica M9. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Sony websites.


Review summary

So how do things add up? Is the Leica M8 better than the Sony A7 III or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Leica M8:

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

ilogo

Reasons to prefer the Sony Alpha A7 III:

  • More detail: Has more megapixels (24 vs 10.4MP), which boosts linear resolution by 52%.
  • Better image quality: Scores substantially higher (37 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3.9 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p 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.
  • 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 (922k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (10 vs 2 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.

  • Faster buffer clearing: Supports Ultra High Speed (UHS-II and UHS-I) SDXC cards.
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More modern: Reflects 11 years and 5 months of technical progress since the M8 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 III is the clear winner of the contest (25 : 3 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 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.

M8 03:25 A7 III

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M8 or the A7 III. 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 why hands-on reviews by experts are important. 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
