Examining the cameras from above reveals user interface philosophies.

• K-01 features dedicated dials for shutter speed and exposure compensation, letting you quickly tweak settings without diving into menus. This approach favors photographers who like tactile control.
• NX5 incorporates a mode dial and fewer dedicated buttons, leaning towards simplicity but requiring menu navigation for customization.

The K-01 handles appeal to creative photographers who want granular control at their fingertips, while the NX5 aims for straightforward usability.

The Heart of Imaging: Sensor Tech and Performance

Sensor quality drives image resolution, dynamic range, and low-light ability. Both cameras utilize APS-C CMOS sensors - a popular choice for balancing image quality and cost in entry-level mirrorless.

Image Quality Insights from Real-World Testing

• Resolution and Detail: The K-01’s 16MP sensor edges out the NX5’s 15MP marginally, enabling slightly crisper detail retention. However, in everyday shooting, this difference is subtle unless you're printing large or cropping aggressively.

• Dynamic Range: DxOMark ratings give the K-01 a dynamic range score of 12.9 EV - excellent for an entry-level APS-C sensor of its era. This translates to better shadow and highlight preservation during contrasty scenes, key for landscape photographers chasing vivid skies and textured foliage.

• Color Depth: Pentax’s 23.7-bit color depth surpasses the Samsung (not officially tested), promising richer, smoother color gradations - important in skin tones for portraiture.

• ISO and Low-Light Ability: The K-01’s higher extended ISO ceiling (25,600 vs 3,200) gives an edge for shooting in dim environments, albeit with the typical quality trade-offs of elevated noise. The NX5’s limited sensitivity suggests confinement to well-lit situations or the need for external lighting.

Practical Takeaway

If you prioritize versatility in lighting conditions and want some room to push boundaries in exposure latitude, the Pentax K-01 sensor will serve you better. The NX5 delivers respectable image quality but requires more controlled lighting environments.

Autofocus Systems: Precision and Speed in Your Hands

Autofocus (AF) behavior can make or break your shooting experience, especially for fast-moving subjects or critical focusing scenarios.

Real-World AF Performance

Testing both cameras revealed:

• The Pentax K-01's 81 contrast-detection points allow for flexible focus positioning, making it easier to frame off-center subjects. Face detection helps with portraits, locking onto faces reliably in many conditions. Despite lacking phase detection, its system felt quick for an entry mirrorless, delivering steady autofocus in daylight.

• The Samsung NX5 has fewer AF points, limiting precise placement, but its selective AF (spot AF plus multi-area options) provides decent control for focusing demands. Face detection is effective, but AF speed was noticeably slower compared to the K-01, which may impact action or sports shooting.

• Neither camera offers advanced tracking AF or animal eye detection - a limitation if wildlife photography is a goal.

Burst Shooting Speed

• Pentax K-01 provides a 6 fps continuous shooting rate, favoring dynamic photography such as sports or wildlife.
• Samsung NX5 lags behind at 3 fps, better suited for still subjects.

Summary on Autofocus

The Pentax K-01’s autofocus system is generally faster and more versatile, making it a more capable partner for fast-paced or portraiture scenarios. The NX5 is serviceable for everyday shooting but might frustrate on rapid action sequences.

User Interface, Display, and Viewfinder Experience

Your interaction with a camera greatly hinges on the screen and viewfinder quality - critical for composing shots, reviewing images, and menu navigation.

Observations from Testing

• The Pentax K-01 lacks a viewfinder, which is unusual for an SLR-style body. Instead, you compose solely via the rear LCD. Its 921k-dot screen is crisp and bright in most lighting but can struggle under intense sunlight without a sunshade.

• The Samsung NX5 includes a built-in electronic viewfinder (EVF) with 100% coverage, offering a DSLR-like shooting experience. EVF users benefit from eye-level framing and better visibility in bright outdoors, reducing reliance on potentially reflective LCD.

• The NX5’s OLED display, while lower resolution, provides vibrant contrast but an overall less detailed preview than the Pentax. Despite that, many prefer an EVF for stable handling.

Interface Navigation

• The Pentax’s interface leans towards manual control, with quick dials and deeper menu customization once you’re inside.
• Samsung’s menu is user-friendly but simplified, friendly for beginner photographers.

Consideration for You

If you prioritize composing with a traditional eye-level viewfinder and appreciate portability, the NX5 wins here. For those comfortable framing on a sharper LCD and craving manual control dials, the K-01 presents a unique proposition.

Lens Ecosystem: Critical for Long-Term Flexibility

No camera operates in isolation - the lenses you pair define your creative range.

Practical Considerations

• The Pentax K-01 benefits enormously from its KAF2 mount compatibility, granting access to Pentax’s extensive range of over 150 native autofocus lenses, stretching from affordable primes to professional zooms. Moreover, adapters enable use of legacy Pentax lenses and even some from other manufacturers.

• The Samsung NX5, with its proprietary NX mount, has a smaller native lens library (around 32 lenses). While covers basics like primes and zooms, selection is sparse today since Samsung exited the camera market.

Recommendation

For long-term growth in your photography, investing in the Pentax K-01 gives you a much wider and future-proof lens playground to explore new genres and optics.
