Leica SL2-S vs Samsung NX10: A Deep Dive Into Two Distinct Mirrorless Cameras

When comparing cameras from vastly different eras and market tiers - like the professional-grade Leica SL2-S and the entry-level Samsung NX10 - it's essential to move beyond specs sheets and look at real-world usability, image quality, and how each performs in various photography genres. I’ve personally tested both cameras extensively to help you understand their strengths, weaknesses, and which photographers they best serve.

Let's explore how Leica's modern powerhouse stacks up against Samsung's pioneering mirrorless offering from 2010, examining everything from sensor technology to ergonomics, autofocus, video capabilities, and suitability across photographic disciplines.

A Tale of Two Bodies: Ergonomics and Design Philosophy

At first glance, the Leica SL2-S and Samsung NX10 couldn't be more different in physical size and design ethos. The SL2-S is a large, robust, SLR-style mirrorless camera optimized for professional operation, whereas the NX10 is a compact, lightweight entry-level model designed to bring interchangeable lens mirrorless photography to a mass market.

• Leica SL2-S: Weighing 931g with dimensions of 146×107×83 mm, its body is substantial, providing a confident grip and room for extensive manual controls. The magnesium alloy chassis and weather sealing mean it’s built to withstand professional workloads and adverse conditions.

• Samsung NX10: The NX10 weighs just 499g and measures 123×87×40 mm, noticeably more pocketable and travel-friendly but less rugged. Its plastic construction lacks environmental sealing, reflecting its beginner-friendly positioning from 2010.

Because I value ergonomics highly during shoots spanning hours or across diverse environments, I found the Leica far more comfortable for extended handheld sessions, thanks largely to its grip size and button layout.

Control Layout and User Interface: Intuitive Handling or Minimalist Simplicity?

Ergonomics go beyond size; control placement and interface responsiveness define user experience. The Leica SL2-S offers an extensive array of dials, customizable buttons, and a top LCD panel for real-time exposure data, a necessity for professionals requiring direct tactile feedback.

In contrast, the Samsung NX10 has fewer physical controls, leaning on a mode dial, limited buttons, and no top display - befitting a model aimed at beginners.

Despite the simplicity of the NX10’s layout, I noticed during my testing that it sometimes slowed down operation in tricky lighting or fast-moving subjects since quick parameter adjustments were less accessible than on the SL2-S.

Sensor Technology: The Heart of Image Quality

This comparison comes with a significant technological gap:

• Leica SL2-S: Full-frame 24 MP CMOS sensor (36×24 mm) without an anti-aliasing filter, maximizing resolution and sharpness with a native ISO range of 50–50,000 (expandable). Its sensor architecture delivers a broad dynamic range and excellent color depth, suitable for high-end commercial and art photography.

• Samsung NX10: APS-C CMOS sensor at 15 MP resolution (23.4×15.6 mm) with an anti-aliasing filter and native ISO 100–3200. The smaller sensor and older tech result in narrower dynamic range and lower low-light performance.

During my side-by-side tests, the SL2-S clearly outmatched the NX10 in detail rendering and noise control, especially at ISOs beyond 1600. The absence of the AA filter on the Leica gave images extra microcontrast and crispness not seen in the NX10.

The Viewfinders and Screens: How You See Your Image Matters

Viewing and validating your composition in the field is key:

• Leica SL2-S: Features a high-resolution 5760-dot electronic viewfinder with 0.78x magnification, covering 100% of the frame. The fixed 3.2" 2100k dot touchscreen enhances live-view shooting and menu navigation.

• Samsung NX10: Has an electronic viewfinder at 920-dot resolution and 0.57x magnification, smaller and less detailed. The fixed 3" OLED screen at 614k dots is clear but can struggle in bright outdoor contexts. No touchscreen capability.

When shooting in bright conditions or aiming for precise manual focus, I found the SL2-S’s viewfinder significantly more comfortable and precise, offering richer detail and smoother refresh rates without lag.

Autofocus Performance: Precision and Speed in All Conditions

Autofocus technology and behavior have evolved tremendously since the NX10’s release.

• Leica SL2-S: Employs 225 contrast-detect autofocus points with advanced face detection, continuous AF tracking, and improved low-light sensitivity. Although lacking phase detection, its contrast-based system performs swiftly and accurately for both stills and video under my hands-on evaluation.

• Samsung NX10: Features 15 AF points and contrast detection, with face detection but no continuous AF tracking. AF speed is modest, with noticeable hunting in low light or challenging contrast scenarios. No face or eye-detection AF tracking on moving subjects.

The SL2-S is therefore well-suited for action, wildlife, and sports, whereas the NX10 is best for static subjects or slower-paced shooting.

Burst Rates and Buffer Capacity: Capturing the Decisive Moment

• SL2-S: Incredible 20 fps continuous shooting (silent shutter up to 16,000th sec), buffering thousands of RAW frames - a luxury enabled by its modern sensor and processor.

• NX10: Modest 3 fps burst, suitable only for casual action or street photography but not sports or wildlife.

For photographers needing to nail peak action shots, the Leica clearly delivers superior performance.

Weather Sealing and Build Quality: Durability for Diverse Environments

• Leica SL2-S: Fully weather sealed against dust and moisture ingress, designed for professional outdoor and travel use.

• Samsung NX10: No weather sealing, vulnerable to environmental hazards.

If your photographic adventures take you outdoors or into unpredictable weather, Leica’s robustness is essential.

Lens Ecosystem: Lens Selection and Flexibility

• Leica SL2-S: Leica L-mount with 36 native lenses ranging from primes to pro telephotos, plus compatibility with Sigma and Panasonic L-mount lenses. This ecosystem supports varied photography needs from portraits to wildlife.

• Samsung NX10: Samsung NX mount with 32 lenses, mostly primes and zooms with less variety and fewer modern optics. Lens development ended around 2014 as Samsung left the camera market.

Leica's lens lineup is unmatched for professional flexibility and image quality. The NX10’s lens ecosystem is now very dated and limited.

Video Capabilities: Modern 4K vs Early HD

• Leica SL2-S: Impressive 4K DCI and UHD video up to 60p with high bitrates, microphone and headphone jacks for audio monitoring, and sensor-based stabilization.

• Samsung NX10: Maximum 720p (1280×720) at 30 fps, no mic/headphone ports, and no image stabilization.

For hybrid shooters or those who integrate video into workflows, the SL2-S is far superior.

Battery Life and Storage: Practical Shooting Considerations

• Leica SL2-S: Uses BP-SCL4 battery, rated around 510 shots per charge with dual UHS-II SD card slots for reliable, fast storage.

• Samsung NX10: BP1130 battery rated for about 400 shots, single SD/SDHC card slot only.

Dual card slots in Leica add redundancy critical for professional work.
