Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark II and the Leica SL3? 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 physical size and weight of the Canon 5D Mark II and the Leica SL3 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.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica SL3 is notably smaller (12 percent) than the Canon 5D Mark II. However, the Leica SL3 is slightly heavier (0 percent) than the 5D Mark II. 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 5D Mark II gets 850 shots out of its Canon LP-E6 battery, while the Leica SL3 can take 320 images on a single charge of its Leica BP-SCL6 power pack. The power pack in the Leica SL3 can be charged via the USB port, which can be very convenient when travelling.

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 5D Mark II was launched at a markedly lower price (by 50 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. 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.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the Leica SL3 offers a higher resolution of 60.3 megapixels, compared with 21 MP of the 5D Mark II. This megapixels advantage translates into a 70 percent gain in linear resolution. On the other hand, these sensor specs imply that the Leica SL3 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.79μm versus 6.41μm for the 5D Mark II). However, it should be noted that the Leica SL3 is much more recent (by 15 years and 5 months) than the 5D Mark II, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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 Canon 5D Mark II are 28.1 x 18.7 inches or 71.3 x 47.5 cm for good quality, 22.5 x 15 inches or 57.1 x 38 cm for very good quality, and 18.7 x 12.5 inches or 47.5 x 31.7 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 Canon EOS 5D Mark II has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Leica SL3 are ISO 100 to ISO 100000, with the possibility to increase the ISO range to 50-100000.
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.

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").

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Leica SL3 provides a better video resolution than the 5D Mark II. It can shoot movie footage at 8K/30p, while the Canon is limited to 1080/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the Leica SL3 has an electronic viewfinder (5760k dots), while the 5D Mark II 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 viewfinder in the Leica SL3 offers a wider field of view (100%) than the one in the 5D Mark II (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Leica SL3 has a higher magnification (0.76x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 5D Mark II and Leica SL3 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Leica SL3 has a touchscreen, while the 5D Mark II 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 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 5D Mark II writes its imaging data to Compact Flash cards, while the Leica SL3 uses CFexpress (type B) or SDXC cards. The Leica SL3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 5D Mark II only has one slot.
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 Canon EOS 5D Mark II and Leica SL3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Leica SL3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 5D Mark II does not provide wifi capability.
Studio photographers will appreciate that the Canon 5D Mark 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 5D Mark II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 5D Mark II was succeeded by the Canon 5D Mark III. Further information on the features and operation of the 5D Mark II and Leica SL3 can be found, respectively, in the Canon 5D Mark II Manual (free pdf) or the online Leica SL3 Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the Leica SL3 is the clear winner of the contest (26 : 6 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.
How about other alternatives? Do the specifications of the Canon 5D Mark II and the Leica SL3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 5D Mark II or the Leica SL3 perform in practice. 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 expert reviews are important. 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.

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.
