Leica S1 Comparison Review

The Leica S1 Pro is a mirrorless interchangeable lens camera that was announced in August 1996 and is equipped with a medium format sensor. It offers a resolution of 26.4 megapixel.

Is the Leica S1 a good camera? The S1 has a Camera Elo of 741. This rating puts the S1 below average of all mirrorless interchangeable lens cameras. In terms of its sensor size category (medium format cameras), the S1 also ranks below average. Based on its within category standings, the camera earns a 2.5-star performance rating. – Well, the Leica S1 is more than 28 years old, and there have been many other good digital cameras released since 1996.

Read on to find out more about the camera's size, sensor, features, reception by expert reviewers, and how it compares to other digital cameras.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Leica S1 was launched in the US market at a price of $21,499. 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 with a 35mm slide

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

The Leica S1 features a medium format sensor and has a format factor (sometimes also referred to as "crop factor") of 0.85. Within the spectrum of camera sensors, this places the Leica S1 among the large-sensor cameras that aim for top notch image quality.

For most 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Connection 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, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the S1. 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 where reviews by experts come in. The adjacent 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]).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
