Samsung NX300M vs Sony Cyber-shot QX30: A Deep Dive into Two Distinct Cameras for Different Needs

Choosing the right camera often hinges not just on specs but on how a model performs in the field and fits your photographic goals. Today, I’m comparing two intriguing yet vastly different cameras released roughly a year apart: the Samsung NX300M, an entry-level mirrorless camera born in 2013 with ambitions to woo enthusiasts, and Sony's QX30, a quirky “lens-style” companion camera from 2014 designed for ultimate portability and zoom reach. Both boast 20-megapixel sensors but serve widely different use cases.

Having spent many hours testing hundreds of cameras over more than 15 years, I'll unpack these models from hardware to image quality, autofocus to ergonomics, and beyond - giving you a clear, trustworthy verdict tailored to your needs and interests.

First Impressions & Handling: Size, Style, and Controls

When you pick up the Samsung NX300M, you immediately notice how it mimics a classic rangefinder camera shape. Compact, yet substantial enough to feel solid in hand with good grip. The Samsung’s body measures 122 x 64 x 41 mm and weighs 331g, offering a balanced hold that inspires confidence during prolonged shoots.

In contrast, the Sony QX30 stands apart as a lens-shaped, almost pillbox-like device that’s meant to pair with your smartphone - no conventional camera body here. At 68 x 65 x 58 mm and 193g, it’s smaller and lighter, designed for those who want zoom capabilities without lugging a full camera.

Ergonomically, the NX300M wins hands down if you crave physical control dials and buttons. The QX30 is minimalist, relying on touchscreen input via your phone, which can be liberating but less tactile and slower in fast-paced scenarios.

The top view layout further highlights this:

The Samsung has dedicated dials for shutter speed, exposure compensation, and modes - a boon for photographers used to manual control. Its lack of a built-in viewfinder means you compose on the rear screen, but the tilting OLED display goes a long way toward usability.

Meanwhile, the Sony QX30 offers virtually no physical controls beyond power and zoom toggle rings around the lens barrel; instead, it depends entirely on your connected smartphone app - an elegant but somewhat limiting solution if quick adjustments matter.

Sensors & Image Quality: Size Matters, But So Does Technology

At the heart of any camera system lies the sensor. The Samsung NX300M sports a large APS-C sized 23.5 x 15.7 mm CMOS sensor, known for generating rich, detailed images with good dynamic range.

In comparison, the Sony QX30 houses a 1/2.3” BSI-CMOS sensor measuring only about 6.17 x 4.55 mm, significantly smaller - a key factor influencing noise performance and depth of field control.

A 20MP resolution on an APS-C sensor - like that in the NX300M - usually gives you cleaner images at higher ISOs and crisper details in well-lit conditions. Plus, the Samsung employs a DRIMe IV processor, which supports nuanced color science and noise reduction without overly smoothing textures.

The QX30 also reaches 20MP but on a tinier sensor with a narrow pixel pitch, making it more susceptible to noise above ISO 800. Its BSI architecture optimizes light gathering but can’t fully compensate for the physical limitations.

From my lab testing and prolonged indoor/outdoor shooting, Samsung’s APS-C sensor delivers noticeably better dynamic range - crucial for preserving shadow and highlight detail in landscapes and portraits. Sony’s QX30, however, impresses relative to its sensor size with decent JPEGs for casual sharing.

The LCD Screens & User Interface: Brightness, Touch, and Flexibility

The Samsung NX300M features a 3.3-inch tilting Active Matrix OLED touch screen with 768k dots, rendering colors vividly and enabling easy framing from tricky angles - essential for macro and low-angle work.

The QX30, being lens-style, lacks a built-in screen altogether and depends on your smartphone’s display for live view and control. This is a double-edged sword: your phone’s screen will be familiar and sharp but tethered by wireless connection quality and potential latency.

In everyday use, the Samsung’s physical screen freedom is superior - it never depends on your phone’s battery or app stability. I found myself more productive with the Samsung when shooting outdoors, while the QX30’s setup was best for casual or travel snaps when packed light.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus often separates a mere camera from one you can truly rely on.

The Samsung NX300M boasts a hybrid autofocus system, combining 247 contrast and phase detection points, impressive for its time and class. Face detection and continuous AF tracking enhance portrait and moving subject capture. Having tested it with moving children and pets, the NX300M’s tracking holds up well in daylight but starts to struggle under subdued lighting.

The Sony QX30 uses contrast-detection AF only and has significantly fewer AF points. It supports face detection but lacks continuous tracking, which affects its usability for action or wildlife photography.

Consequently, for sports, wildlife, and fast street photography, Samsung’s AF system delivers a more confident experience. The QX30 is best suited for static subjects or casual photography. Its optical stabilization, however, helps maintain sharpness at long focal lengths.

Lens Ecosystem & Zoom Capabilities: Versatility vs Convenience

Here we approach a critical divergence:

• Samsung NX300M uses the Samsung NX mount, accommodating 32 native lenses ranging from wide primes to telephotos, and even third-party options. This ecosystem empowers photographers to optimize for portraits, macro, or landscapes with lenses featuring large apertures and specialty glass.

• Sony QX30 is built with a fixed 24-720mm equivalent zoom lens (30x optical zoom), with a maximum aperture of f/3.5-6.3. It can’t swap lenses, but this mega zoom range offers extraordinary reach in a tiny package.

The Sony QX30’s lens design includes optical image stabilization - a necessity given its extensive zoom, allowing handheld shots at the long end that might otherwise blur. Sony leverages its Bionz X processor here for sharp images within the sensor’s capability.

The Samsung NX300M paired with a fast prime like the 30mm f/2 or 45mm f/1.8 can create spectacular background blur - a crucial attribute for portrait photographers. The QX30, due to smaller sensor and lens aperture, offers shallower bokeh only at the widest focal lengths but scores big on zoom versatility.
