Leica S1 vs Nikon Zf

The Leica S1 Pro and the Nikon Zf are two digital cameras that were revealed to the public, respectively, in August 1996 and September 2023. Both the S1 and the Zf are mirrorless interchangeable lens cameras that are based on a medium format (S1) and a full frame (Zf) sensor. The Leica has a resolution of 26.4 megapixels, whereas the Nikon provides 24.3 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 S1 Pro and the Nikon Zf? 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

An illustration of the physical size and weight of the Leica S1 and the Nikon Zf is provided 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.

The Zf can be obtained in seven different colors (black, grey, brown, blue, red, orange, green), while the S1 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Zf is considerably smaller (80 percent) than the Leica S1. Moreover, the Zf is substantially lighter (72 percent) than the S1. It is noteworthy in this context that the Zf is splash and dust-proof, while the S1 does not feature any corresponding weather-sealing.

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 power pack in the Zf 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. 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The Zf was launched at a markedly lower price (by 91 percent) than the S1, 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. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica S1 features a medium format sensor and the Nikon Zf a full frame sensor. The sensor area in the Zf is 34 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.85 and 1.0. The sensor in the S1 has a native 1:1 aspect ratio, while the one in the Zf offers a 3:2 aspect.

With 26.4MP, the S1 offers a slightly higher resolution than the Zf (24.3MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 7.01μm versus 5.94μm for the Zf) due to its larger sensor. However, the Zf is a much more recent model (by 27 years) than the S1, 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 S1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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

Unlike the S1, the Zf 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 S1 Pro has a native sensitivity range from ISO 50 to ISO 1600. The corresponding ISO settings for the Nikon Zf are ISO 100 to ISO 64000, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the S1 is build around a CCD sensor, while the Zf uses a BSI-CMOS imager. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The Zf indeed provides for movie recording, while the S1 does not. The highest resolution format that the Zf can use is 4K/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the Zf has an electronic viewfinder (3690k dots), while the S1 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 following table reports on some other key feature differences and similarities of the Leica S1, the Nikon Zf, and comparable cameras.

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

One feature that differentiates the Zf and the S1 is in-body image stabilization (IBIS). The Zf reduces the risk of handshake-induced blur with all attached lenses, while the S1 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, the Zf 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 Nikon Zf 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 S1 writes its imaging data to external storage, while the Zf uses SDXC cards.

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 S1 Pro and Nikon Zf and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Zf offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the S1 does not provide wifi capability.

The Zf is a recent model that features in the current product line-up of Nikon. In contrast, the S1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the S1 was succeeded by the Leica S2. 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 how do things add up? Is the Leica S1 better than the Nikon Zf or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Leica S1 Pro:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in August 1996).

Arguments in favor of the Nikon Zf:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• High quality composites: Can combine several shots after pixel-shifting its sensor.
• Broader imaging potential: Can capture not only stills but also 4K/60p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Rear screen: Has a backside LCD (3.2") for image review and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (14 vs 0.01 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (144x103mm vs 339x214mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 1790g or 72 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
• More modern: Reflects 27 years of technical progress since the S1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the Zf is the clear winner of the contest (22 : 4 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 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 S1 and the Nikon Zf 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 S1 or the Zf 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 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
