View this as your authoritative guide to understand how they perform beyond just specs, aiding you in making a confident purchase decision tailored to your photography ambitions.

Size, Ergonomics, and Handling - First Impressions Matter

The Samsung NX30 presents itself as a mid-sized mirrorless with an ergonomically friendly grip and SLR-style body design. Measuring 127 x 96 x 58 mm and weighing around 375 grams, it feels substantial without being unwieldy. Notably, its extensive physical controls provide tactile responsiveness prized by users who prefer manual adjustments without fumbling through menus.

Conversely, the Sony RX100 V epitomizes pocket-friendly, compact camera engineering with dimensions of just 102 x 58 x 41 mm and a featherweight 299 grams. Its design targets discreet street and travel photography without compromising technical cutting-edge features.

Both cameras include tilting or fully articulating LCD screens vital for creative composition angles (more on displays later), but the NX30’s larger body notably allows for a bigger handgrip and a more comfortable shooting experience over long sessions. The RX100 V’s compactness caters well to photographers prioritizing ultra-portability and stealth.

Controls and Interface - Navigating the Camera in Action

Looking top-down, the NX30 reveals a classic mirrorless control scheme: dedicated dials for shutter speed, ISO, and exposure compensation, combined with tactile buttons that facilitate quick mode and focus point changes. This arrangement scaffolds rapid manual shooting - a crucial advantage for demanding portrait and landscape work - or any scenario necessitating precision settings.

On the RX100 V, control allocation is necessarily minimalistic. While it includes a mode dial and a multi-function control ring around the lens for aperture or zoom, it relies more on menu navigation and the intelligent autofocus system to simplify user interaction. This design suits users who prefer a streamlined interface or those transitioning from smartphone photography.

From personal testing, the NX30’s interface speeds workflows in complex lighting or fast-action scenes where dial-and-button immediacy reduces missed shots, whereas the RX100 V’s setup suits spontaneous shooting with minimal user input.

Sensor Technology and Image Quality - Where Detail and Dynamic Range Compete

At the heart of any camera is its sensor. The Samsung NX30 sports an APS-C sized CMOS sensor measuring 23.5 x 15.7 mm with a 20 MP resolution, accompanied by an anti-aliasing filter to balance sharpness and moiré suppression. This sensor size (roughly 369 mm² surface area) significantly outperforms the RX100 V’s 1-inch BSI-CMOS sensor measuring 13.2 x 8.8 mm (~116 mm²), albeit both offering equivalent nominal pixel counts.

In practical terms, this sensor size advantage translates to better light gathering ability for the NX30, enhancing low-light image quality, noise control, and dynamic range. DxOMark testers registered a DXO overall score of 77 for the NX30, versus 70 for the RX100 V. Both deliver around 12.4 EV dynamic range at base ISO, but the NX30’s color depth (23.5 bits vs. 22.8 bits) and low light ISO performance (1014 versus 586) underscore the advantages of larger physical pixels.

From experience shooting both cameras under varied conditions (studio portraits, landscapes at golden hour, and dim interiors), the NX30 consistently offers richer color rendition and cleaner shadows when pushing ISO values. The RX100 V, while impressive for a compact, reveals noise and detail loss sooner when shooting above ISO 3200.

Rear LCD and Electronic Viewfinder - Composing the Perfect Shot

Both models feature 3-inch screens with high resolution, yet differing technologies affect usability. The Samsung NX30 adopts a fully articulated 1,036k-dot AMOLED touchscreen, striking a rare balance between vibrant color reproduction, deep blacks, and touch interactivity for focus or menu navigation. This is a boon for video shooters or vloggers needing versatile screen positioning for self-recording.

The Sony RX100 V, meanwhile, has a tilting LCD of slightly higher 1,229k dots but lacks touch sensitivity - a nod to its more traditional control approach. Its OLED electronic viewfinder (EVF) matches the NX30’s resolution at 2,359k dots but offers a smaller 0.59x magnification compared to NX30’s 0.66x. While both EVFs cover 100% frame, the NX30’s EVF provides a marginally larger view, enhancing manual focus precision under challenging conditions.

Practical testing underscores the NX30’s articulating touchscreen as advantageous during macro work or awkward angles, while the RX100 V’s tilt screen and EVF combo suffice for street and travel photographers accustomed to rapid framing without live preview touch inputs.

Autofocus – Speed, Precision, and Reliability in Varied Scenarios

Autofocus systems underpin a camera’s responsiveness in real shooting. The NX30 features a hybrid autofocus combining 247 focus points leveraging both phase-detection and contrast detection, delivering fast and accurate focus acquisition and low hunting. The system also supports touch-AF for intuitive focusing on the AMOLED screen and effectively tracks subjects with continuous AF modes.

In contrast, the RX100 V’s autofocus employs 315 phase-detection points covering approximately 65% of the frame, further augmented by contrast detection. This sophisticated system enables extremely fast shutter lag and accurate tracking, particularly beneficial during burst shooting at 24 fps, a marquee feature of the RX100 V.

However, the NX30’s extensive AF system paired with interchangeable lenses provides greater flexibility in autofocus behavior adjustments, especially in portraiture where eye detection (not supported in either camera) is less critical than reliable center or multi-area lock.

During wildlife and sports shoots - areas demanding rapid acquisition and tracking - the RX100 V’s 24 fps burst and advanced AF outperform the NX30’s more modest 9 fps continuous shooting rate. Yet, for slower-paced but precise focus tasks (macro, landscape), the NX30’s hybrid AF system offers confidence and control.

Lens Ecosystem and Optical Versatility - A World of Choices vs. Fixed Convenience

One of the primary divergences arises from lens compatibility. The Samsung NX30 utilizes the Samsung NX mount, supported by 32 native lenses ranging from wide-angle primes to telephoto zooms. The availability of diverse focal lengths and apertures empowers photographers to tailor optical setups to specialized genres such as macro, portrait, or sports photography. This modularity, however, comes with added bulk and cost for acquiring lenses.

Conversely, the Sony RX100 V comes equipped with a fixed 24-70mm equivalent zoom lens with a bright aperture range of f/1.8 to f/2.8. While this eliminates the need to swap lenses - streamlining portability and battery economy - it limits optical reach and depth-of-field control compared to interchangeable lens systems.

For example, achieving creamy bokeh and ultra-shallow depth-of-field portraits is more attainable on the NX30 paired with a fast prime lens, whereas the RX100 V’s smaller sensor and lens bayonet constrain background blur smoothness.

In macro photography, the NX30 combined with dedicated close-focusing lenses excels in the sub-1:1 magnification domain, while the RX100 V's 5cm macro focal range offers good close-up performance, suitable for occasional close focusing but less specialized.

Burst Shooting and Video Capabilities - Fast Action and Moving Pictures

Delivering on both stills and video demands, these cameras take divergent paths. The RX100 V excels in burst shooting at an astonishing 24 fps with continuous autofocus - remarkable for a compact - making it ideal for sports and wildlife photography requiring precise timing and subject tracking. Video recording capabilities are also strong, with UHD 4K @ 30p capture supported alongside high bitrate XAVC S codec, enabling superb sharpness and gradation.

The NX30 lags in these departments with a maximum continuous shooting speed of 9 fps and 1080p Full HD video recording capped at 60p, without 4K options. It offers microphone input for enhanced audio capture, an element attractive to serious video creators, but lacks headphone output for audio monitoring - a notable omission.

Image stabilization is another distinguishing factor: RX100 V integrates optical image stabilization crucial for steady video and handheld shooting, whereas the NX30 lacks in-body or lens stabilization, relying on lens-based stabilization if available.

In essence, for high-frame-rate action photography and cutting-edge video recording (including 4K), the RX100 V stands out as the superior tool despite fixed optics. For casual video or stills, the NX30 still delivers professional exposure controls and flexible recording options.

Build Quality, Weather Resistance, and Durability - Handling the Elements

While neither camera is weather sealed, the NX30’s more substantial body and robust construction lend confidence to sustained outdoor use, especially in moderate conditions. Its shutter mechanism rated for about 100,000 actuations and traditional DSLR-like ergonomics instill durability and reliability for professional workflows.

The RX100 V’s compactness inherently limits ruggedness and offers no environmental sealing; its mechanical complexity (pop-up EVF, folding screen) requires careful handling. That said, Sony’s engineering quality ensures resilience for travel photographers who value size and refinement over ruggedness.

Battery Life and Storage - Practical Concerns for Extended Use

Operating endurance is a key consideration in fieldwork. The NX30 provides approximately 360 shots per charge using its BP1410 battery, surpassing the RX100 V’s 220-shot rating with the smaller NP-BX1 battery. While real-world performance varies depending on screen use and connectivity, the mirrorless system’s larger battery physically supports longer sessions before recharging.

Both cameras utilize a single card slot: NX30 supports SD/SDHC/SDXC, while RX100 V is compatible with SD and Sony’s proprietary Memory Stick formats. For professional shooting, carrying extra cards and batteries is advisable regardless.

Connectivity and Wireless Features

Both cameras incorporate NFC and built-in Wi-Fi for image transfer and remote triggering, significant conveniences for instant sharing or controlling the camera with smartphones. USB 2.0 speeds suffice for general file transfer but lag behind modern USB 3.0 or higher alternatives.
