Body comparison

The physical size and weight of the Leica SL3 and the Sony A77 II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Leica SL3 vs Sony A77 II
Compare Leica SL3 versus A77 II top
Comparison Leica SL3 or A77 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A77 II is somewhat smaller (2 percent) than the Leica SL3. Moreover, the A77 II is markedly lighter (24 percent) than the Leica SL3. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the Leica SL3 gets 320 shots out of its Leica BP-SCL6 battery, while the A77 II can take 480 images on a single charge of its Sony NP-FM500H power pack. The power pack in the Leica SL3 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.

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 A77 II was launched at a markedly lower price (by 83 percent) than the Leica SL3, 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. 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 SL3 features a full frame sensor and the Sony A77 II an APS-C sensor. The sensor area in the A77 II is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica SL3 and Sony A77 II sensor measures

With 60.3MP, the Leica SL3 offers a higher resolution than the A77 II (24MP), but the Leica SL3 has smaller individual pixels (pixel pitch of 3.79μm versus 3.91μm for the A77 II). However, the Leica SL3 is a much more recent model (by 9 years and 10 months) than the A77 II, 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 Leica SL3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica SL3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL3 for good quality output (200 dots per inch) amounts to 47.6 x 31.7 inches or 120.9 x 80.5 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.7 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.6 x 53.6 cm. The corresponding values for the Sony A77 II are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Leica SL3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica SL3 has a native sensitivity range from ISO 100 to ISO 100000, which can be extended to ISO 50-100000. The corresponding ISO settings for the Sony Alpha SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 Leica SL3 has a touchscreen, while the A77 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The A77 II 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 Leica SL3 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 Leica SL3 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 SL3 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 Leica SL3 writes its imaging data to CFexpress (type B) or SDXC cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The Leica SL3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A77 II only has one slot. The Leica SL3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A77 II can use UHS-I cards (up to 104 MB/s).

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 SL3 and Sony Alpha SLT-A77 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Leica SL3 has a headphone jack, which is not present on the A77 II This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Sony A77 II (unlike the Leica SL3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The Leica SL3 is a recent model that features in the current product line-up of Leica. In contrast, the A77 II has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the A77 II from Sony. Further information on the features and operation of the Leica SL3 and A77 II can be found, respectively, in the Leica SL3 Manual (free pdf) or the online Sony A77 II Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the Leica SL3 is the clear winner of the match-up (25 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

How about other alternatives? Do the specifications of the Leica SL3 and the Sony A77 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 Leica SL3 or the A77 II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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 assessments were made in relation to similar cameras of the same technological generation. 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.
