Going beyond this snapshot of core features and characteristics, what are the differences between the Leica SL (Typ 601) and the Fujifilm X-H1? 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 Leica SL and the Fujifilm X-H1 are illustrated 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 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 Fujifilm X-H1 is notably smaller (11 percent) than the Leica SL. Moreover, the X-H1 is markedly lighter (21 percent) than the Leica SL. 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 SL gets 400 shots out of its Leica BP-SCL4 battery, while the X-H1 can take 310 images on a single charge of its Fujifilm NP-W126S power pack. The power pack in the X-H1 can be charged via the USB port, 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-H1 was launched at a markedly lower price (by 75 percent) than the Leica SL, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica SL features a full frame sensor and the Fujifilm X-H1 an APS-C sensor. The sensor area in the X-H1 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.

Even though the Leica SL has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the Leica SL has a lower pixel density and larger individual pixels (with a pixel pitch of 6.00μm versus 3.92μm for the X-H1), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the X-H1 is much more recent (by 2 years and 3 months) than the Leica SL, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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 X-H1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica SL (Typ 601) has a native sensitivity range from ISO 50 to ISO 50000. The corresponding ISO settings for the Fujifilm X-H1 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 100-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the Leica SL uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-H1 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond 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 Leica SL offers a higher resolution than the one in the X-H1 (4400k vs 3690k dots). The following table reports on some other key feature differences and similarities of the Leica SL, the Fujifilm X-H1, and comparable cameras.

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

One feature that differentiates the X-H1 and the Leica SL is in-body image stabilization (IBIS). The X-H1 reduces the risk of handshake-induced blur with all attached lenses, while the Leica SL offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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 SL and the Fujifilm X-H1 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.

Concerning the storage of imaging data, both the Leica SL and the X-H1 write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. However, while the X-H1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s) on both slots, the Leica SL supports UHS-II only on its first slot and UHS-I (data transfer speed up to 104 MB/s) on the second one.

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 SL (Typ 601) and Fujifilm X-H1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Leica SL has a headphone jack, which is not present on the X-H1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the Leica SL has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the Leica SL and the X-H1 have been discontinued, but can regularly be found used on ebay. The Leica SL was replaced by the Leica SL2, while the X-H1 does not have a direct successor. Further information on the features and operation of the Leica SL and X-H1 can be found, respectively, in the Leica SL Manual (free pdf) or the online Fujifilm X-H1 Manual.

Review summary

So how do things add up? Which of the two cameras – the Leica SL or the Fujifilm X-H1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica SL (Typ 601):

• 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 sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (4400k vs 3690k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.80x vs 0.75x).
• Longer lasting: Can take more shots (400 versus 310) on a single battery charge.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in October 2015).

Reasons to prefer the Fujifilm X-H1:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
• Faster burst: Shoots at higher frequency (14 vs 11 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (140x97mm vs 147x104mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 174g or 21 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
• More modern: Reflects 2 years and 3 months of technical progress since the Leica SL launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Leica SL emerges as the winner of the contest (12 : 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 SL and the Fujifilm X-H1 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Leica SL or the X-H1. 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 where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
