Sensor Technology and Image Quality: APS-C Mirrorless vs Small Sensor Superzoom

At the heart of image quality lies sensor size and technology. The Samsung NX300M boasts a 20MP APS-C CMOS sensor - significantly larger than the Sony HX400V’s 1/2.3" (6.17 x 4.55 mm) BSI-CMOS sensor. This is a decisive technical difference, directly affecting resolution, dynamic range, noise, and depth rendering.

Samsung NX300M:

• Sensor size: APS-C (23.5 x 15.7 mm), approx. 369 mm²
• Resolution: 20MP, max image size 5472 x 3648 pixels
• Native ISO range: 100–25600
• Equipped with anti-aliasing filter for sharper images
• Outputs RAW format for maximum editing flexibility
• DRIMe IV processor optimizing image fidelity

Sony HX400V:

• Sensor size: 1/2.3" (6.17 x 4.55 mm), approx. 28 mm²
• Resolution: 20MP, max image size 5184 x 3888 pixels
• Native ISO range: 80–12800
• Has anti-aliasing filter
• No RAW support; outputs JPEG only
• Bionz X processor focused on noise reduction and sharpening at high zoom

In real-world tests, the NX300M’s larger sensor delivers significantly better low-light performance with less noise beyond ISO 1600. The dynamic range advantage is also apparent - shadow recovery in RAW files is notably superior. Colors appear more natural and skin tones more nuanced, an important factor for portrait work.

The HX400V’s sensor, although 20MP nominally, suffers from smaller photosites and increased noise at higher ISO. It’s tailored more for daylight shooting with decent detail at wide angles but loses fine detail when zoomed extensively. Its JPEG-only output limits post-processing latitude.

• RAW support is a clincher for professionals and enthusiasts who edit

Autofocus and Speed: Precision and Tracking in Action

Autofocus performance is mission-critical for wildlife, sports, and fast-moving subjects.

Samsung NX300M:

• Hybrid autofocus: phase detection + contrast detection
• 247 focus points covering nearly entire frame
• Features face detection and continuous AF tracking
• Touch-to-focus on AMOLED touchscreen
• Continuous shooting: 9 fps (frames per second)

Sony HX400V:

• Contrast detection AF system only
• 9 focus points centered in frame
• Face detection and tracking present but less flexible
• No touch focus - reliant on joystick and buttons
• Continuous shooting: 10 fps, though AF is single-shot only

From my testing, the NX300M’s hybrid AF significantly improves focus acquisition speed, especially in good light. The wide AF coverage and continuous tracking are effective for portrait and wildlife use but can struggle in very low contrast or low light conditions.

The HX400V’s slower contrast detection AF can be frustrating when tracking erratically moving subjects, but its zoom lens compensates by letting you pre-compose shots at long focal lengths. Continuous AF is unavailable during burst shooting, limiting sports usability.

Stage-Specific Autofocus Notes

• Portrait: NX300M’s face and eye detection superior, yielding sharper eyes in portraits
• Wildlife: NX300M better for fast-moving creatures at shorter telephoto ranges; HX400V’s 50x zoom unmatched for distant wildlife but AF lags
• Sports: NX300M preferred for continuous AF and higher burst rate; HX400V better for static or slow-action scenarios

Build Quality, Weather Resistance, and Reliability

Neither camera offers significant weather sealing, nor are they ruggedized for heavy professional use. However, build quality perceptions differ:

• Samsung NX300M: Lightweight plastics dominate, suitable for casual everyday use but not demanding conditions
• Sony HX400V: More robust-feeling plastic with rubberized grip, adding confidence in handheld telephoto shooting but still no sealing

Both cameras operate reliably under average environmental conditions but exercise caution in inclement weather.

Viewfinder and LCD Screen: Framing Versatility

A good viewfinder or LCD is vital for compositions across disciplines.

Samsung NX300M:

• 3.3-inch tilting AMOLED touchscreen (768k dots)
• No built-in EVF, which limits precise framing in bright sunlight
• Touch interface very responsive for selecting AF points, reviewing images

Sony HX400V:

• 3.0-inch tilting LCD with 921k dots (non-touch)
• Electronic viewfinder covering 100% frame, essential for telephoto framing accuracy
• Traditional button and dial controls on top and back

For outdoor use, the HX400V’s built-in EVF is a huge advantage, particularly when using long zoom lengths where holding the camera steady is critical. The NX300M’s tilting touchscreen excels for creativity and convenience in live view but is handicapped by the lack of finder.

Lens Ecosystem and Compatibility

One of Samsung NX300M’s biggest advantages is its interchangeable lens mount system. The Samsung NX mount currently supports 32 lenses, including primes, zooms, and specialized optics like macro and tilt-shift lenses (though limited availability now post Samsung’s departure from the camera business).

The HX400V uses a built-in fixed superzoom lens ranging from 24 mm to 1200 mm equivalent, with an aperture range of f/2.8-6.3.

• NX300M’s system enables significant creative flexibility: fast primes for portraits, tilt-shifts for architecture, macro lenses for close-ups
• HX400V offers unparalleled reach in a single package but sacrifices optical quality compared to professional primes

If you like swapping lenses depending on subject, the NX300M is the better route; if convenience and reach trump everything, HX400V stands out.
