Going beyond this snapshot of core features and characteristics, what are the differences between the Leica SL3-S and the Nikon Z50 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

The side-by-side display below illustrates the physical size and weight of the Leica SL3-S and the Nikon Z50 II. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions 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 Nikon Z50 II is notably smaller (19 percent) than the Leica SL3-S. Moreover, the Z50 II is substantially lighter (35 percent) than the Leica SL3-S. 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Convert to Imperial

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Z50 II was launched at a markedly lower price (by 83 percent) than the Leica SL3-S, 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 SL3-S features a full frame sensor and the Nikon Z50 II an APS-C sensor. The sensor area in the Z50 II is 57 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 24MP, the Leica SL3-S offers a higher resolution than the Z50 II (20.7MP), but the Leica SL3-S nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.22μm for the Z50 II) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 Leica SL3-S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL3-S 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 Nikon Z50 II are 27.8 x 18.6 inches or 70.7 x 47.1 cm for good quality, 22.3 x 14.8 inches or 56.6 x 37.7 cm for very good quality, and 18.6 x 12.4 inches or 47.1 x 31.4 cm for excellent quality prints.

Unlike the Z50 II, the Leica SL3-S has the capacity to capture high quality composite images (96MP) 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 SL3-S has a native sensitivity range from ISO 100 to ISO 50000, which can be extended to ISO 50-100000. The corresponding ISO settings for the Nikon Z50 II are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 100-204800.

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.

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"). 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Leica SL3-S provides a higher video resolution than the Z50 II. It can shoot video footage at 6K/30p, while the Nikon is limited to 4K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the Leica SL3-S offers a substantially higher resolution than the one in the Z50 II (5760k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Leica SL3-S, the Nikon Z50 II, and comparable cameras.

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

One feature that is present on the Leica SL3-S, but is missing on the Z50 II 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 SL3-S and the Nikon Z50 II both have 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-S writes its imaging data to CFexpress (type B) or SDXC cards, while the Z50 II uses SDXC cards. The Leica SL3-S features dual card slots, which can be very useful in case a memory card fails. In contrast, the Z50 II only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 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-S and Nikon Z50 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the Leica SL3-S and the Z50 II are recent models that are part of the current product line-up. The Z50 II replaced the earlier Nikon Z50, while the Leica SL3-S followed on from the Leica SL2-S. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Nikon websites.

Review summary

So what is the bottom line? Is the Leica SL3-S better than the Nikon Z50 II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Leica SL3-S:

• More detail: Offers more megapixels (24 vs 20.7MP) with a 8% higher linear resolution.
• High quality composites: Can combine several shots after pixel-shifting its sensor.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher definition movie capture (6K/30p vs 4K/60p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.68x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (2333k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (30 vs 11 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (315 versus 250) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.

Reasons to prefer the Nikon Z50 II:

• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (127x97mm vs 141x108mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 302g or 35 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (83 percent cheaper at launch).

If the number of relative strengths (bullet points above) is taken as a guide, the Leica SL3-S is the clear winner of the match-up (18 : 6 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.

How about other alternatives? Do the specifications of the Leica SL3-S and the Nikon Z50 II 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 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 Leica SL3-S or the Z50 II perform in practice. 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.

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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
