Samsung NX5 vs Sigma fp: An Expert Hands-On Comparison You Can Trust

Choosing a mirrorless camera is never straightforward, especially when models come from brands with vastly different heritage and design philosophies. The Samsung NX5 and Sigma fp sit almost a decade apart, yet both target serious photographers wanting versatile mirrorless systems. I’ve put these two through their paces - testing image quality, autofocus, handling, and more - to help you decide which one fits your shooting style, budget, and creative ambitions.

I’ve tested thousands of cameras during my 15+ years as a reviewer, so I’ll cut through marketing fluff and give you seasoned, practical insights based on real-world use rather than just specs on paper. Whether you’re a beginner stepping up from a smartphone or a pro looking for a reliable workhorse, this detailed comparison will serve you well.

First Impressions: Size, Build, and Handling

At first glance, these cameras couldn't be more different. The Samsung NX5 wields a traditional SLR-style mirrorless design - chunky, with a strong grip and familiar button layout. In contrast, the Sigma fp is almost chameleon-like: a tiny, rangefinder-style box with minimalist controls that beg you to accessorize.

Samsung NX5: Weighing in at 499g and measuring 123x87x40mm, the NX5 feels substantial without being overly heavy. Its SLR-style body gives it that comfortable, well-rounded grip, ideal for those of us who like our cameras to nestle into the hands like a trusted club. Buttons and dials are logically placed and provide decent tactile feedback, perfect for shooting in changing conditions or when wearing gloves.

Sigma fp: This compact gem is lighter at 422g and smaller overall (113x70x45mm), making it one of the smallest full-frame mirrorless cameras around. It’s essentially a modular firearm for your fingers - you won’t find a built-in grip or many controls. The lack of a built-in viewfinder nudges you toward using the LCD constantly, and the absence of dedicated buttons means you’ll need to rely more on touchscreen menus or external accessories.

Long story short, if you favor ergonomics and intuitive physical controls, the NX5 feels more comfortable and familiar. Meanwhile, the Sigma fp is a flexible, minimalist platform, perfect if you like building your own rig or prefer stealthy, lightweight shooting.

Sensor Tech and Image Quality: APS-C vs Full-Frame Showdown

Digital sensor technology is where these cameras inhabit different universes altogether.

Samsung NX5: Features a 15MP APS-C CMOS sensor (23.4x15.6mm) with a 1.5x crop factor. Back in 2010, 15 megapixels was fairly standard, and the DRIM Engine processor helped produce decent JPEGs with reasonable dynamic range. However, the sensor’s age shows in its limited ISO range (100-3200 native), and image quality can degrade noticeably in low light.

Sigma fp: This is where the fp truly shines - a 25MP full-frame BSI-CMOS sensor (35.9x23.9mm). Being back-illuminated (BSI) means it gathers light more efficiently, boosting high-ISO performance. The fp supports an impressive 100–25600 native ISO, expandable to 6–102400, giving you great flexibility in dim environments or astrophotography. The larger sensor area of 858 mm² (versus 365 mm² on the NX5) means better noise control, richer tonality, and superior depth of field control.

Results? The fp produces stunningly clean, detailed images with wider dynamic range and better color depth - a professional-grade advantage. The NX5 still can hold its own under bright, well-lit situations but struggles in contrasty scenes and higher ISO shooting.

Controls and User Interface: Buttons, Screens, and Menus

How a camera controls and interacts with you can make or break your shooting experience.

Samsung NX5: The control layout is approachable - the NX5 offers discrete dials for shutter speed and exposure compensation, plus a traditional PASM mode dial. Its interface is simple but effective, particularly for beginner or enthusiast shooters transitioning from DSLRs. The 3-inch OLED screen with a resolution of 230k dots is small by modern standards but produces vibrant colors and good viewing angles. However, it lacks touch functionality.

Sigma fp: Ditching physical dials for an austerity approach, the fp relies on a 3.2-inch LCD touchscreen boasting an extraordinary 2.1 million dots, delivering ultra-sharp previews and easy menu navigation. The touchscreen adds a modern feel, letting you tap focus and swipe through settings swiftly. But the lack of a built-in EVF can be limiting outdoors or for fast-paced shooting, pushing you to either an optional external viewfinder or just live view mode.

The difference here boils down to preference: do you want physical dials for direct access, or sleek minimalism paired with a superb touchscreen? If you’re used to classic SLR controls, the NX5 feels more natural; if you crave a futuristic, stripped-down interface with step-up screen real estate, the fp excels.

Autofocus Performance: Tracking, Speed, and Accuracy

Autofocus is where user experience frequently wins or loses in real-world photography.

Samsung NX5:

• Contrast-detection system with 15 focus points (no PDAF)
• Face detection enabled but no eye/animal tracking
• AF speed maxes out at a modest 3fps continuous shooting
• Lags behind modern systems in tracking moving subjects, prone to hunting in low light

Sigma fp:

• Contrast-detection only but significantly enhanced with 49 autofocus points and AF tracking features
• Face detection included, plus eye detection - very handy for portraits
• Full HD live view autofocus shows greater precision
• Burst shooting at 12fps with AF tracking improves chances for sharp wildlife and sports shots (even if buffer isn't deep)

Neither camera employs phase-detection autofocus, which is common in modern mirrorless systems, so neither handles extreme action shooting perfectly. However, the Sigma fp's higher frame rate and better AF tracking software provide a big edge for sports and wildlife photographers.

Lens Ecosystem and Compatibility

Samsung NX5: The NX mount system comes with around 32 native lenses covering standard zooms, primes, and some specialty optics. Samsung’s lineup (now discontinued) was respectable for an entry-level system, with reasonable autofocus performance. However, since Samsung exited the camera business after this generation, the ecosystem is stagnant, limiting lens options and future investment.

Sigma fp: Uses the Leica L-mount, benefiting from the alliance between Leica, Panasonic, and Sigma. This mount offers compatibility with a growing range of high-quality lenses from all three manufacturers, as well as adapters for third-party glass. This ecosystem advantage means the fp’s lens options are more expansive, future-proof, and premium quality.

Summary: For variety and long-term viability, the Sigma fp has the distinct advantage thanks to the L-mount alliance.

Build Quality and Weather Sealing

Samsung NX5: Plasticky but decent build quality. No environmental sealing or ruggedization; vulnerable to dust and moisture. Fit for casual use in controlled environments.

Sigma fp: Surprisingly robust aluminum body with IP52 environmental sealing (dust and splash resistant). Not rugged, but definitely more durable than the NX5. This makes the fp a better choice for outdoor, travel, and event shooters who need reliability in tougher weather.

Battery Life and Storage

Samsung NX5: Uses a BP1130 battery rated for around 400 shots per charge. No surprise here - it aligns well with cameras of its era. Single SD/SDHC slot.

Sigma fp: Battery life is notoriously short - often under 250 shots per charge - due to the high-res sensor and 4K capabilities. It accepts SD/SDHC/SDXC UHS-II cards, enabling speedy data rates for video. Single card slot remains a downside for professionals needing backup.

Battery-wise, the NX5 wins on endurance, but the fp demands carrying spares or using external power solutions for longer shoots or extensive video.

Video Capabilities: From HD to 4K Pro-Quality

Video is an area where the Sigma fp leaps ahead.

Samsung NX5:

• Max HD video resolution at 1280x720p at 30fps
• Uses H.264 codec, no 4K support
• No microphone/headphone jacks
• Limited video recording features (no timelapse, no 4K photo modes)
• Good for casual family or travel video, nothing more

Sigma fp:

• Full 4K UHD (3840x2160) video at 30p, encoded in MPEG-4/H.264 with Linear PCM audio
• Equipped with microphone and headphone jacks for audio monitoring and professional sound capture
• Supports timelapse recording directly in-camera
• Minimal internal stabilization; best used with gimbals or lens-stabilized optics

This makes the Sigma fp an excellent choice for hybrid shooters who prioritize top-notch video alongside stills. The Samsung NX5 just can’t match its quality or features here.

Versatility Across Photography Genres

Let’s break down how each camera performs for specific photography styles and needs:

Portraits

• Samsung NX5: Polycarbonate body and modest sensor make for decent portraits; facial detection helps but no eye AF. APS-C crop limits shallow depth of field effects but acceptable with fast lenses. Bokeh is pleasant but basic.
• Sigma fp: Full-frame sensor and eye detection autofocus give a professional edge: cleaner skin tones, creamy bokeh, and better subject isolation. A dream for portrait studios or lifestyle photographers.

Landscapes

• Samsung NX5: 15MP resolution somewhat limiting; moderate DR and dynamic range gap visible especially in shadows/highlights. No weather sealing makes outdoor shooting riskier.
• Sigma fp: 25MP + full-frame + strong DR and ISO latitude create exquisitely detailed landscape files. Weather sealing adds shoot-anywhere confidence.

Wildlife

• Samsung NX5: Slow AF and 3fps burst rate not ideal; lens selection limited for telephoto reach; suitable only for casual wildlife enthusiasts.
• Sigma fp: 12fps continuous with AF tracking is a big plus; L-mount ecosystem includes tele lenses. Great for serious wildlife photographers in terms of speed and quality.

Sports

• Samsung NX5: Autofocus lags behind rapid movement; frame rates slow; better suited to slower action.
• Sigma fp: Higher burst speed with more focus points makes it a plausible option for amateur sports shooters; pro sports shooters probably want more specialized gear but fp stands out for hybrid needs.

Street

• Samsung NX5: SLR body less discreet; decent low light but bulkier.
• Sigma fp: Compact and lightweight - top marks for street candidness, portability, and discreet shooting.

Macro

• Both support manual focussing, but the larger sensor and better live view zoom on the fp help nail precise focus. NX5’s limited resolution and no stabilization options hold it back.

Night & Astro

• Samsung’s low max ISO hampers shooting stars or neon-lit cityscapes.
• Sigma’s massive ISO range and clean output dominate this genre.

Travel

• NX5 heavier but more battery life.
• Sigma fp win with weight and image quality but demands battery planning.

Professional Work

• NX5 aimed more at amateurs.
• Sigma fp: Full RAW, 4K video, pro connectivity (mic, headphone jack), and solid build make it a contender for professional hybrid work even if EVF is missing.

Display and Viewfinder Quality

Samsung’s 3” OLED screen is decent but small and low-res by today’s standards - fine for basic framing but limited for focus checking or high-res playback. The NX5 includes a 100% coverage electronic viewfinder, which many still swear by for composing and shooting in bright light.

The Sigma fp, on the other hand, lacks any built-in EVF but compensates with a stunning 3.2" 2.1M-dot touchscreen. This screen is bright and detailed enough to shoot in place of a viewfinder, but outdoor usability can suffer in strong sunlight. Many users opt for the optional loupe-style external EVF Sigma offers.

Connectivity and Extras

Neither camera features Wi-Fi, Bluetooth, or NFC for wireless image transfer or remote control - Samsung’s NX5 lacks wireless entirely. This absence limits modern workflows that rely on smartphone tethering or rapid sharing.

Both have HDMI ports but only the fp has microphone/headphone jacks for serious audio/video use.
