Leica SL2-S vs Samsung NX30: A Deep Dive into Two Distinct Mirrorless Worlds

Choosing your next camera can feel like navigating a labyrinth - especially when the contenders come from vastly different eras and brands, each with unique philosophies and technologies. Today, I’m taking you through a detailed comparison of two mirrorless cameras that, at first glance, publish very different stories: the modern Leica SL2-S, launched in late 2020 as a professional full-frame powerhouse, and the 2014 vintage Samsung NX30, a passionate “advanced mirrorless” with an APS-C sensor aimed at enthusiasts. Though these cameras cater to different segments, comparing them head-to-head shines light on how camera technology has evolved, and what practical impact that has across a variety of photographic disciplines.

I have spent hours testing both extensively under real-world conditions - feeling their ergonomics, probing autofocus in challenging scenarios, scrutinizing image quality, and considering factors such as workflow, ergonomics, and lens ecosystems. By the end, you’ll understand which one might fit your photographic style, budget, and creative ambitions.

A Tale of Two Designs: Size and Handling First

Before we dive into sensors and autofocus, it’s worth addressing how these cameras feel in the hand. Ergonomics shape your shooting experience more than many realize, especially on long assignments.

The Leica SL2-S is a substantial device, sporting an SLR-style mirrorless body with dimensions of 146 x 107 x 83mm and weighing a hefty 931 grams. Its robust magnesium alloy chassis incorporates extensive environmental sealing - dust and splash resistance included - to withstand professional use in challenging climates. The grip is deep and comfortable, balancing the lens weight nicely, which is crucial given Leica’s L-mount lenses tend to be premium glass with considerable heft.

Compare that to the Samsung NX30, which feels like a compact, lightweight camera by today’s standards (127 x 96 x 58mm, 375 grams). The leaner build fits perfectly into smaller bags and excels in situations where discretion and portability matter, such as street or travel photography. However, its plastic-heavy construction lacks weather sealing, limiting durability outside controlled environments.

If you prize solid build quality and weather resistance for professional use, the SL2-S takes a clear win here. Conversely, the NX30 serves well in nimble, casual shooting scenarios where a lightweight camera can go unnoticed.

User Interface: Control Layout Meets Modern Convenience

Handling isn’t just about size - the control layout can make or break your shooting flow. Leica’s SL2-S embraces a clean, minimalist design with logically placed dials and buttons flagship photographers expect, prioritizing a tactile experience without unnecessary clutter.

What stands out on the SL2-S is its illuminated, precise electronic viewfinder (EVF) offering a 5.76-million-dot resolution - one of the highest in the industry - with 0.78x magnification. The rear 3.2-inch, 2.1 million-dot fixed touchscreen delivers razor-sharp live view and intuitive menu navigation. The presence of dual card slots (both supporting fast UHS-II SD cards) is a boon for professionals handling high volumes or requiring instant backups.

The NX30, for its part, offers a fully articulating 3-inch AMOLED touchscreen with a decent 1.03 million dots. Its EVF is smaller and lower resolution (2.359 million dots with 0.66x magnification), reflective of its enthusiast-grade positioning. Storage is limited to a single SD card slot, which constrains workflow for heavy shooters.

Samsung’s addition of a selfie-friendly articulating screen and built-in flash caters to casual photographers and vloggers. However, the NX30's overall control scheme, while more complex than entry-level cameras, lacks dedicated buttons for frequently adjusted settings - a frustration for faster workflows.

In sum, the SL2-S delivers a more refined, professional control experience, while the NX30 offers convenience features that appeal to enthusiast and social shooters.

Sensor and Image Quality: Full Frame vs. APS-C – The Core Battle

When comparing cameras from different generations, the sensor remains the pillar affecting image quality, low-light capability, and depth of field control.

The Leica SL2-S features a full-frame CMOS sensor measuring 36 x 24mm (864 square mm) delivering 24 megapixels. While not the highest megapixel count in Leica’s lineup, the sensor’s architecture prioritizes superior dynamic range, tonal fidelity, and extremely clean high ISO performance - critical for professional portrait, landscape, and low-light work. Interestingly, Leica eschewed the anti-aliasing filter to maximize image sharpness, a bold choice that demands excellent lenses but rewards detail-hungry photographers.

On the other end, the Samsung NX30 houses a 20-megapixel APS-C CMOS sensor sized 23.5 x 15.7mm (369 square mm). Compared to full-frame, APS-C sensors naturally gather less light, which can affect noise performance and depth of field control. The NX30’s sensor includes an anti-aliasing filter, which reduces moiré but can slightly soften fine details. Despite the age and smaller sensor, Samsung's DRIMe IV processor provides respectable image quality with good color reproduction and dynamic range for its class.

Looking at raw ISO sensitivity, the Leica spans 50 to 50,000 native (expandable), while the NX30 extends up to ISO 25,600. However, in practical terms, the SL2-S manages high ISO shots with distinctly cleaner noise characteristics, making it a better pick for night, astro, or indoor low-light shooting.

For landscape photographers craving the broadest tonal latitude and the ability to print enormous gallery-quality prints, Leica’s larger sensor and bit-depth provide a decisive advantage. Enthusiasts shooting casual travel, street, or social subjects in good light may find the NX30’s sensor sufficient, albeit with less latitude in post.

Autofocus Systems Put to the Test: Speed, Accuracy, and Tracking

Autofocus (AF) performance is critical across numerous photography disciplines. I spent hours shooting both stills and video, tracking fast-moving subjects and confirming focus precision under challenging lighting.

The Leica SL2-S uses a 225-point contrast-detection AF system with face detection and touch-enabled AF - adapted for professional video and stills. Notably, the camera lacks phase detection AF points, which are traditionally superior for tracking. However, Leica’s algorithmic refinement means that continuous autofocus is impressively fluid and reliable for static subjects and moderately paced movement. Unfortunately, there is no animal eye AF - a minor downside for wildlife and pet photographers who rely on this cutting-edge feature in competing models.

The NX30 couples 247 cross-type phase-detect AF points with contrast detection for hybrid autofocus. Even in 2014, this system was quite advanced, and it delivers snappy focus acquisition in good light. Continuous AF tracking performs reasonably well for sports and casual wildlife, but the older technology sometimes struggles in low-contrast or low-light situations.

In summary, although the Samsung’s hybrid AF system allows faster initial focus lock, the Leica’s system is built for meticulous accuracy and smooth video AF. Fast-action sports shooters will likely find the NX30’s AF system more responsive; portrait and video shooters will appreciate the SL2-S’s precision and touch interface.

Shooting Speeds: Can They Keep Up with Your Action?

Burst shooting rates can make the difference between a missed opportunity and a gallery-worthy sequence.

The LEICA SL2-S can capture up to 20 frames per second using its electronic shutter - a remarkable speed for a pro full-frame mirrorless. This capability opens doors for dynamic sports, wildlife, or event shooting, where split-second timing is vital. The mechanical shutter tops out at 8 frames per second, still respectable for many professional use cases.

Samsung’s NX30 supports 9 frames per second continuous shooting. While not groundbreaking by today's standards, this is very good for the camera's category and era. Notably, the NX30 lacks a silent electronic shutter option, presenting limitations to discreet shooting in quiet surroundings.

From hands-on trials, when shooting fast sports or wildlife, the SL2-S’s higher FPS combined with large buffer capacity shines, giving you confidence to capture decisive moments continuously.

Video Capabilities: Beyond Stills for the Hybrid Shooter

Leica designed the SL2-S as a hybrid system targeted to professionals who want serious stills and video performance rolled into one.

It shoots 4K UHD (4096x2160 and 3840x2160) up to 60p, with high-quality H.264 codec and linear PCM audio, complete with microphone and headphone jacks for monitoring and input. Internal video bitrates can reach 400 Mbps, promising very detailed footage. The sensor-based image stabilization supports smoother hand-held footage.

The NX30, meanwhile, outputs 1080p Full HD video maxing out at 60p. It lacks 4K recording and doesn’t provide headphone output, which limits its appeal for professional videographers. The built-in microphone port allows audio input but without monitoring, underscoring its status as an enthusiast camera.

Thanks to Leica's advanced video-oriented features and hardware, the SL2-S is suitable for serious filmmaking projects and hybrid workflows. Samsung’s NX30 is more appropriate for casual video content and social media clips.

Lens Ecosystem: The Glass That Shapes Your Images

An often overlooked but vital factor is the lens mount and available lenses, which influence creative options and potential.

Leica’s SL2-S uses the L-mount, benefiting from the L-Mount Alliance among Leica, Panasonic, and Sigma - offering over 36 native lenses ranging from ultra-wide to super-telephoto primes and zooms, many crafted to high professional standards. These lenses are known for exquisite rendering, solid build, and weather sealing, matching the camera body’s pedigree.

The Samsung NX30 relies on the now-defunct Samsung NX mount with roughly 32 lenses developed during its brief lifespan - limited mostly to consumer-grade primes and zooms. With Samsung exiting the camera business, availability and future-proofing are concerns. While there are some adaptors to use other glass, native options are scarce and discontinued.

For longevity, creativity, and professional-quality optics, the Leica ecosystem vastly outclasses Samsung’s offering here.

Battery Life and Storage: Practicality on the Go

Battery life impacts how long you can shoot before hunting for a recharge. The SL2-S’s BP-SCL4 battery provides about 510 shots per charge, depending on usage - quite good for a full-frame mirrorless with a high-res EVF. Combined with dual UHS-II SD card slots, the camera suits extended professional use.

The NX30’s BP1410 battery delivers around 360 shots per charge - adequate but noticeably shorter than Leica’s. It has a single card slot supporting standard SD, SDHC, and SDXC, limiting backup options but fine for casual travel or street use.

If you often shoot all day or require uninterrupted sessions, Leica’s battery and dual card memory solution offer a more confident experience.

Connectivity and Wireless Functions: Tethered or Mobile

Connectivity options play a role for workflow efficiency, especially as mobile and IoT integration grows.

Leica equips the SL2-S with built-in Wi-Fi and Bluetooth for remote control, image transfer, and firmware updates. It also offers USB 3.2 Gen 1 (5 Gbps) for fast wired transfers and an HDMI port for external monitors.

Samsung’s NX30 has built-in Wi-Fi and NFC to pair with compatible devices for image transfers and remote control. USB 2.0 connectivity, while standard at its launch, is significantly slower than modern interfaces.

Leica's faster transfer speeds and better wireless integration support professional workflows better, especially when huge RAW files are involved.
