Although Fujifilm and Hasselblad are credited with popularising medium format photography with their respective GFX 50S and X1D models, the Leica S, introduced back in 2008 is widely considered the first medium format camera that can be regarded as genuinely “portable.”
However, the S2 was the company’s last major upgrade. Considering the high cost and limited availability of Leica products, it is not surprising that the brand has partially fallen off of people’s radars.
But with the new Leica S3, introduced at Photokina 2018, the Leica S is back and better than ever. The sensor has a resolution of 64 megapixels, 14 megapixels more than the Fujifilm and Hasselblad cameras. Additionally, it can record 4K video without cropping the image, which is highly outstanding for a sensor of this size and resolution.
Unfortunately, Leica cannot provide us with any information on the price of the Leica S3. Still, considering that the body solely of the preceding Leica S2 sold for £16,000/$23,000, it is safe to assume that the S3 will not be inexpensive.
Leica S3 Build Quality
Mirrorless cameras may dominate the news, but Leica has stuck with a DSLR design for the S3. When you put the camera to your eye, you are immediately struck by the optical viewfinder’s size, clarity, and brightness. Mirrorless cameras may dominate the headlines, but Leica has stuck with a DSLR design.
The body of the S3 has the same refined, uncluttered, and rounded appearance as the model before it. There is a stark selection of unmarked buttons on the back of the device, a control dial (also unmarked), and a status panel on the top plate. The S3 is not an appropriate camera for novice photographers.
It is inherently more significant than a DSLR with a full frame, but the difference is not as significant as you might anticipate. The extra height in the body provides you with a solid hold around the body (the size of a grip is equally as crucial as its depth), and the relatively few buttons ensure that you can throw this camera about without accidentally pressing any of the button controls.
The design of the S3 is expected to provoke conflicting reactions from consumers. It is smooth, polished, sophisticated, and a joy to hold, but it is a camera that will require some learning.
Leica S3 Sensor & Video
The S3 has a 64-megapixel CMOS sensor that measures 30 x 45 millimeters to create a high degree of clarity, sensitivity, and a broad dynamic range certified for up to 15 stops. Its excellent resolution is one of its defining characteristics.
In addition, this “Leica ProFormat” sensor has no optical low-pass filter built into its design. This was done to achieve the highest possible level of sharpness. In addition to improving resolution, the modernized design enables a broad sensitivity range that extends from ISO 100 to ISO 50000 and supports continuous shooting at up to 3 frames per second.
In terms of focusing, a predictive phase-detection autofocus system is speedy, quiet, and advantageous for tracking moving subjects because it utilizes a single central cross-type point. This type of point can be found in the camera’s sensor.
The upgraded sensor allows for the taking of still photographs and enables impressive video capabilities. It can record in DCI 4K at 24 frames per second and Full HD at up to 30 frames per second, and both formats can utilize the entire width of the sensor.
The 3.5mm port allows for the connection of an external microphone, and the HDMI Type-C port enables external recording in 4:2:2 8-bit color sampling. In addition, it can support up to Full HD resolution.
Leica S3 Performance
For such a large lens, the Summarit-S 70 f/2.5 ASPH CS lens focuses incredibly quickly and smoothly, making it the most comparable lens to a “kit” lens that can be used with this camera.
Although the S3 model we tested was an early pre-production version, we look forward to evaluating the camera’s image quality as soon as a loan sample is made available to us. Leica is confident, however, that its S-series lenses quickly have the resolving power to match the 64MP sensor and could cope with future resolutions of 100MP and beyond.
Only connoisseurs and professionals with bottomless pockets will likely be able to afford a Leica S3, but the camera’s design, handling, and overall feel are quintessential Leica. If you can pay for it, you will find it well worth the money.
