Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M8 and the Sony Alpha A7R II? 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 M8 and the Sony A7R II 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 A7R II 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 Sony A7R II is notably larger (10 percent) than the Leica M8. Moreover, the A7R II is markedly heavier (6 percent) than the M8. It is noteworthy in this context that the A7R II 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 (A7R II).

Concerning battery life, the M8 gets 550 shots out of its Leica BLI-312 battery, while the A7R II can take 290 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A7R II can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 A7R II was launched at a markedly lower price (by 42 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 M8 features an APS-H sensor and the Sony A7R II a full frame sensor. The sensor area in the A7R II is 77 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.

With 42.2MP, the A7R II offers a higher resolution than the M8 (10.4MP), but the A7R II has smaller individual pixels (pixel pitch of 4.52μm versus 6.84μm for the M8). Yet, the A7R II is a much more recent model (by 8 years and 8 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 A7R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 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 A7R II 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 A7R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the M8 is build around a CCD sensor, while the A7R II uses a BSI-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 consideration, the A7R II offers substantially better image quality than the M8 (overall score 39 points higher). The advantage is based on 4.9 bits higher color depth, 2.6 EV in additional dynamic range, and 2.4 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 also of capturing video footage. The A7R II indeed provides for movie recording, while the M8 does not. The highest resolution format that the A7R II can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7R II has an electronic viewfinder (2400k 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 table below summarizes some of the other core capabilities of the Leica M8 and Sony A7R II in connection with corresponding information for a sample of similar cameras.

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

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 A7R II 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 M8 writes its imaging data to SDXC cards, while the A7R II uses SDXC or Memory Stick PRO Duo cards. The A7R II supports UHS-I cards (Ultra High Speed data transfer of up to 104 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 Sony Alpha A7R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R II 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 A7R II have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the A7R II was followed by the Sony A7R III. Further information on the features and operation of the M8 and A7R II can be found, respectively, in the Leica M8 Manual (free pdf) or the online Sony A7R II Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica M8 or the Sony A7R II – 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 M8:

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

If the count of individual advantages (bullet points above) is taken as a guide, the A7R II is the clear winner of the contest (21 : 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.

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 A7R II. 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 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, please note that some of the review sites have changed their methodology and reporting over time.
