Sony A7 III vs Leica M8

The Sony Alpha A7 III and the Leica M8 are two enthusiast cameras that were officially introduced, respectively, in February 2018 and September 2006. The A7 III is a mirrorless interchangeable lens camera, while the M8 is a rangefinder-focusing mirrorless. The cameras are based on a full frame (A7 III) and an APS-H (M8) sensor. The Sony has a resolution of 24 megapixels, whereas the Leica provides 10.4 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Sony A7 III and the Leica M8 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 M8 can be obtained in two different colors (black, silver), while the A7 III is only available in black.

Size Sony A7 III vs Leica M8
Compare A7 III versus M8 top
Comparison A7 III or M8 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M8 is notably smaller (9 percent) than the Sony A7 III. Moreover, the M8 is markedly lighter (9 percent) than the A7 III. It is worth mentioning in this context that the A7 III is splash and dust resistant, 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 Sony FE Lens Catalog (A7 III) and the Leica M Lens Catalog (M8).

The power pack in the A7 III can be charged via the USB port, so that it is not always necessary to take the battery charger along 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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons 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 A7 III was launched at a markedly lower price (by 64 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. 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. 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 Sony A7 III features a full frame sensor and the Leica M8 an APS-H sensor. The sensor area in the M8 is 43 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7 III and Leica M8 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). However, 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 pixels. Coming back to sensor resolution, it should be mentioned that the M8 has no anti-alias filter installed, so that it can capture all the detail its 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 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 A7 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A7 III has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Leica M8 are ISO 160 to ISO 2500 (no boost).

In terms of underlying technology, the A7 III is build around a BSI-CMOS sensor, while the M8 uses a CCD 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.

A7 III versus M8 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the A7 III provides substantially higher image quality than the M8, with an overall score that is 37 points higher. This 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range 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. The adjacent table lists some of the other core features of the Sony A7 III and Leica M8 along with similar information for a selection of comparators.

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 A7 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the M8 uses SDXC 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.

It is notable that the A7 III offers wifi support, while the M8 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

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 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 features and operation of the A7 III and M8 can be found, respectively, in the Sony A7 III Manual (free pdf) or the online Leica M8 Manual.

ilogo

Advantages of the Leica M8:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More heavily discounted: Has been around for much longer (launched in September 2006).

If the number of relative strengths (bullet points above) is taken as a guide, the A7 III is the clear winner of the match-up (27 : 4 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.

A7 III 27:04 M8

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A7 III or the M8 perform in practice. 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 expert reviews are important. 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.

The review scores listed above should be treated with care, 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.
