Pentax Q-S1 vs Samsung NX mini: A Thorough Comparison for Entry-Level Mirrorless Cameras in 2024

Choosing the right entry-level mirrorless camera can be a daunting task, especially when options come with diverse sensor sizes, lens ecosystems, and feature sets. Today, we dive deeply into a side-by-side comparison of two distinctive entry-level mirrorless cameras released in 2014: the Pentax Q-S1 and the Samsung NX mini. Although both aimed at casual photographers and beginners extending their photography journey, they took fundamentally different technical and design approaches that resonate distinctly today.

Drawing from over 15 years of exhaustive hands-on camera evaluations, I’ll provide a methodical, expert-driven comparison grounded in practical photography performance, sensor analysis, ergonomics, autofocus behavior, lens compatibility, and video capability, among other critical factors.

Sizing Up: Body Design and Ergonomics

First impressions often center on camera handling and size. Both the Pentax Q-S1 and Samsung NX mini employ a rangefinder-style mirrorless layout but differ noticeably in build and portabilities.

• Pentax Q-S1 measures a compact 105 x 58 x 34 mm, weighing 203 grams.
• Samsung NX mini is slightly slimmer and wider at 110 x 62 x 23 mm, coming in lighter at 196 grams.

While the narrower thickness of the NX mini makes it more pocketable (a key advantage for street and travel photographers), the Pentax Q-S1’s deeper body gives a more secure grip for extended handheld shooting, especially with the optional grips available for the Q mount.

Pentax’s more substantial hand feel can be vital for photographers transitioning from compact cameras to mirrors, offering tactile assurance missing from ultra-flat bodies which tend toward minimal controls. Meanwhile, NX mini’s slender profile prioritizes portability over ergonomics.

Control Layout & Usability: Navigating the Interface

Beyond physical dimensions, understanding how each camera lays out critical controls affects workflow speed and shooting comfort.

The Pentax Q-S1 incorporates a clear arrangement of physical dials and buttons, with dedicated mode dials and a well-placed shutter release. However, it lacks touchscreen capability, requiring menu navigation through buttons and directional pads - potentially slower for users accustomed to touch controls.

Conversely, the Samsung NX mini includes a tilting 3-inch touchscreen (with 461K dots), enhancing immediate access to focus points, menu options, and image review via intuitive taps and swipes. However, the NX mini trades off fewer physical controls, which some users might find less precise for rapid adjustments - especially in outdoor bright conditions where screen glare is a concern.

Both cameras include built-in flashes and hot shoes for external flash units, but only the NX mini offers expanded wireless connectivity (built-in Wi-Fi) for instant sharing - a significant feature for modern shooters prioritizing connectivity.

Sensor Technology: The Engine Behind Image Quality

Arguably the most critical determinant of image quality and photographic versatility is the sensor design and resolution.

• Pentax Q-S1: Features a 1/1.7-inch BSI-CMOS sensor measuring 7.44 x 5.58 mm (~41.5 mm²) with a resolution of 12 MP (4000 x 3000 pixels). The sensor includes an anti-aliasing filter for reducing moiré artifacts but inherently limits dynamic range and low-light performance due to its smaller size.

• Samsung NX mini: Utilizes a much larger 1-inch BSI-CMOS sensor sized 13.2 x 8.8 mm (~116.1 mm²) with 20.5 MP resolution (5472 x 3648 pixels). This larger sensor area inherently provides better noise control, wider dynamic range, and finer detail capture.

The sensor size difference is substantial: the NX mini’s sensor surface area is nearly three times larger than that of the Q-S1, offering a clear advantage in image fidelity, especially in low-light shooting or when cropping images.

Pentax’s Q-S1 sensor size is comparable to what you might find in premium compact cameras of that era, offering decent quality but clearly more limited dynamic range and ISO performance than the NX mini’s 1-inch sensor.

Impact in Practical Photography:

• Portraits & Bokeh: The larger sensor and higher megapixel count of the NX mini yield smoother, more natural bokeh and better tonal gradations for skin tones, crucial for portrait work.

• Landscape & Detail: More resolution and better dynamic range on the NX mini provide sharper landscape images with greater shadow recovery potential.

• Low-light & ISO: The NX mini, with an expanded ISO range up to 25600 (boosted), outperforms the Q-S1’s maximum ISO of 12800 due to sensor size and noise handling, leading to usable results in dim environments.

Autofocus Systems: Pinpoint Precision vs Simplicity

Autofocus performance significantly shapes user experience, especially when capturing moving subjects or performing critical focus tasks like portraits or macro photography.

• Pentax Q-S1: Equipped with a contrast-detection AF system with face detection and continuous AF capabilities. However, it lacks sophisticated tracking features such as animal eye AF or phase-detection autofocus. The Q-S1 supports AF area selection modes including center and multi-area, but no phase-detection alloys.

• Samsung NX mini: Also relies on contrast-detection AF but employed 21 focus points, offering more granular AF area coverage. It incorporates touch-to-focus functionality on its touchscreen, which facilitates fast, intuitive AF point selection. Despite being contrast-based, the NX mini does not offer continuous tracking AF (confirmed lack of AF tracking in specs).

In my testing, the NX mini’s AF system locks focus somewhat faster and more reliably under adequate light than the Q-S1. However, in low light or challenging contrast scenarios, both cameras exhibit hunting due to contrast detection without dedicated phase-detection sensors.

Neither is ideal for wildlife or fast sports due to autofocus limitations, but for general photography and casual video use, the NX mini offers a slight edge with its touchscreen AF.

Image Stabilization: Sensor-Based vs None

The Pentax Q-S1 boasts sensor-shift image stabilization, which is a rare feature in entry-level mirrorless cameras from 2014, allowing effective blurring control during handheld shooting and video capture without relying solely on stabilized lenses.

The Samsung NX mini does not incorporate in-body image stabilization; instead, stabilization depends on the lens’ features, though NX-M mount lenses offered very limited options for optical stabilization.

For photographers frequently shooting handheld, indoors, or in low light, the Q-S1's built-in stabilization offers tangible benefits by improving sharpness at slower shutter speeds or while filming video.

Lenses and System Expandability: Ecosystem Depth and Compatibility

An often-overlooked but critical aspect in long-term camera choice is the available lens ecosystem.

The Pentax Q mount system, while small sensor-focused, provided a modest selection of lenses including standard and wide-angle primes and zoom options designed for easy portability.

Samsung’s NX mini system was much more limited with just two native lenses optimized for ultra-compact use - a severe constraint for users who want variety or specialty optics like macro or telephoto.

Neither system offers the extensive third-party lens support enjoyed by more mainstream mirrorless mounts like Sony E or Micro Four Thirds. However, Pentax users benefit somewhat from third-party adapters for legacy Pentax and other manual lenses, granting greater creative lens choices.

User Interface and Screen Quality

The Samsung NX mini hands-down offers a better viewing and interaction experience thanks to its 3-inch tilting touchscreen with 461K-dot resolution. The 180-degree tilt is perfect for vloggers and selfies (despite official specs not labeling it “selfie-friendly” with a front screen, the tilt still enables front viewing). Touch focus and shutter release simplify operation.

The Pentax Q-S1’s fixed 3-inch LCD with 460K-dot resolution lacks touch input, restricting UI navigation to physical buttons and dials, which still cater well to seasoned photographers who prefer tactile controls.

Both cameras lack electronic viewfinders – a notable omission that may limit compositional flexibility in bright sunlight.

Burst Shooting and Shutter Speeds

Performance in capturing action hinges on continuous shooting speed and shutter capabilities.

• Pentax Q-S1 maxes out at 5 fps with shutter speeds ranging from 30s up to 1/8000s.
• Samsung NX mini offers a slightly faster 6 fps burst and goes even faster on maximum shutter speed up to 1/16000s, useful for bright light or wide aperture shooting without ND filters.

Neither camera features an electronic shutter or silent shutter options, which modern mirrorless favor for discrete shooting.

NX mini’s faster shutter range and rapid burst rates present advantages for casual sports or street photography where freezing motion is important.

Video Capabilities: Resolution, Frame Rates, and Audio

Both cameras capture Full HD (1920x1080) video at up to 30fps, with Samsung NX mini supporting additional resolutions including 720p and VGA modes at the same frame rate options.

Key differences:

• The NX mini includes a microphone input jack, a substantial plus for videographers wanting better sound quality with external microphones.
• Pentax Q-S1 lacks both mic and headphone ports; in-camera sound recording is limited.
• Neither camera supports 4K video or advanced video features like log profiles or high frame rate slow motion.
• Both use MPEG-4/H.264 encoding typical for the era but limited in bitrates.

For casual video creators, especially those venturing into vlogging or social sharing, the NX mini’s mic port and touchscreen ease of focus represent key benefits.

Battery Life and Storage

A practical consideration for travel or all-day shoots is power and storage.

Samsung NX mini impresses with a long-lasting battery rated for 650 shots per charge, significantly outpacing the short-lived Pentax Q-S1’s 250 shots. This makes NX mini better suited for extended travel or event coverage without carrying multiple batteries.

On storage, Pentax uses the standard full-sized SD cards, which are more widely available and sometimes cheaper, while Samsung requires microSD cards typically used in smartphones, which may pose slight inconvenience for photographers who already pack larger SD cards.

Durability and Weather Resistance

Neither camera carries weather sealing, dustproofing, or freezeproofing – expected for entry-level bodies of their release era and segment. If you need ruggedness, other lines or more modern cameras should be explored.

Price and Value Proposition in 2024

• Pentax Q-S1: Priced around $250, represents an ultra-budget entry-level option with stabilized sensor and compact lenses but with compromises in sensor size and ecosystem.
• Samsung NX mini: Significantly higher at $530 MSRP (current street prices may vary), reflecting improved sensor performance, touchscreen, better battery life, and video mic support.
