Leica SL2 vs Sony A6500
The Leica SL2 and the Sony Alpha A6500 are two enthusiast cameras that were revealed to the public, respectively, in November 2019 and October 2016. Both the SL2 and the A6500 are mirrorless interchangeable lens cameras that are based on a full frame (SL2) and an APS-C (A6500) sensor. The Leica has a resolution of 46.7 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 SL2 and the Sony Alpha A6500? 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.
The side-by-side display below illustrates the physical size and weight of the Leica SL2 and the Sony A6500. 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 measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6500 is considerably smaller (49 percent) than the Leica SL2. Moreover, the A6500 is substantially lighter (52 percent) than the SL2. 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.
The battery packs of both cameras can be charged via USB, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 A6500 was launched at a markedly lower price (by 77 percent) than the SL2, 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 SL2 features a full frame sensor and the Sony A6500 an APS-C sensor. The sensor area in the A6500 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.
With 46.7MP, the SL2 offers a higher resolution than the A6500 (24MP), but the SL2 nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 3.91μm for the A6500) due to its larger sensor. Moreover, the SL2 is a much more recent model (by 3 years and 1 month) than the A6500, 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 SL2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica SL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Sony A6500 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 A6500 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the A6500, the SL2 has the capacity to capture high quality composite images (187MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Leica SL2 has a native sensitivity range from ISO 100 to ISO 50000, which can be extended to ISO 50-50000. The corresponding ISO settings for the Sony Alpha A6500 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
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"). 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL2 provides a higher frame rate than the A6500. It can shoot video footage at 4K/60p, while the Sony is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the SL2 offers a substantially higher resolution than the one in the A6500 (5760k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Leica SL2, the Sony A6500, and comparable cameras.
|12.||Pentax K-1 II||optical||Y||3.2||1037||full-flex||n||1/8000s||4.4||n||Y|
|14.||Sony A99 II||2400||Y||3.0||1229||full-flex||n||1/8000s||12.0||n||Y|
One feature that is present on the SL2, but is missing on the A6500 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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, both cameras under consideration feature an 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 SL2 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 SL2 writes its imaging data to SDXC cards, while the A6500 uses SDXC or Memory Stick PRO Duo cards. The SL2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A6500 only has one slot. The SL2 supports UHS-II cards (on both slots), while the A6500 can use UHS-I cards.
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 SL2 and Sony Alpha A6500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL2 has a headphone jack, which is not present on the A6500 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 Leica SL2 (unlike the A6500) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The SL2 is a recent model that features in the current product line-up of Leica. In contrast, the A6500 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the A6500 was succeeded by the Sony A6600. 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.

If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the match-up (24 : 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.
How about other alternatives? Do the specifications of the Leica SL2 and the Sony A6500 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SL2 or the A6500. 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.
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], 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 above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
