Samsung NX20 vs Sony Cyber-shot DSC-H55: An Expert Comparison for Every Photographer’s Need
Choosing a camera isn’t easy, especially when two models hail from different categories yet promise enticing features. Here, I’m diving deep into the Samsung NX20, an advanced mirrorless camera launched in 2012, and the Sony Cyber-shot DSC-H55, a compact superzoom also from 2010. While both cameras come from reputable brands, their technological approaches, use cases, and capabilities differ widely. Having personally tested thousands of cameras, I want to guide you through what these two bring to the table, using a practical, hands-on lens - literally and figuratively.
Throughout this discussion, I’ll analyze their respective performances across all key photography disciplines, technical merits, handling qualities, and ultimately give clear recommendations. I’ve even integrated side-by-side image comparisons, detailed sensor analysis, and performance scores to illustrate my points.
Let’s start by looking at how they feel in the hand.
Feel, Size, and Ergonomics – Which One Fits Your Grip?
If you’re serious about photography, how a camera feels can make or break your day shooting. The Samsung NX20 sports a classic SLR-style mirrorless body, while the Sony H55 is a compact point-and-shoot.
Right away, you see the NX20 is larger and heavier (341g vs. 200g) and measures 122x90x40mm compared to the H55’s 103x58x29mm. That extra heft translates into an ingrained confidence - it’s substantial but not cumbersome. The comfortable grip on the NX20 means you can hold it steady for longer periods, especially with larger lenses attached. Meanwhile, the H55’s petite size makes it pocketable and discreet - ideal for travel or casual snapping.
However, the H55 leans more toward convenience over comfort, which you feel after prolonged use. The NX20 offers more physical controls and customizable buttons, a point we’ll expand on later. Its solid battery life (360 shots per charge) far exceeds the smaller compact’s unspecified longevity - a common trait for dedicated mirrorless bodies.
So, if you want a camera that feels like a tool designed for photography’s demands, NX20 is the clear winner ergonomics-wise. If portability and simplicity compel you, the Sony wins in that department.
Control Layout and Top-Panel Design: Handling in the Heat of The Moment
Once in use, how the controls respond determines your shooting flow. Here’s a peek at the top view of both cameras:
In the NX20, I appreciate the layout - shutter speed, exposure compensation, aperture priority, and manual mode dials sit conveniently within thumb and forefinger reach. There’s a dedicated mode dial and a popup flash button, plus a hot shoe for external flashes, expanding creative lighting options. The OLED electronic viewfinder (EVF) completes the package, providing near-instant framing, crucial for action or bright outdoor shooting.
On the Sony H55, there are no dedicated exposure modes like shutter or aperture priority, no manual exposure controls - which might disappoint enthusiasts wanting creative control. The lens zoom is powered (25-250mm), and the controls on top are minimal, mostly limited to the zoom toggle and shutter release. There is no EVF, so you compose primarily on the LCD.
For fast-paced photography or manual exposure adjustments, the NX20 takes the lead. For straightforward point-and-shoot, the H55 manages well enough.
Sensor Technology and Image Quality: The Heart of the Matter
Now let me tackle one of the most crucial aspects: sensor size and resulting image quality.
The Samsung NX20 packs a 20.3MP APS-C CMOS sensor measuring 23.5 x 15.7mm, giving it a sensor area of roughly 369mm² - a substantial size known to deliver superior image quality, especially in low light and with wider dynamic range.
The Sony H55, by contrast, uses a 14MP 1/2.3-inch CCD sensor measuring about 6.17 x 4.55mm (28mm² area). This tiny sensor imposes inherent limitations: less light-gathering ability, more noise at higher ISOs, and generally lower dynamic range.
What does this mean practically? The NX20 produces detailed, clean images with excellent color depth (DxO reported 23.4 bits), wide dynamic range (12.9 EV), and impressive low-light ISO performance (785 score). Its maximum ISO rings from 100 to 12,800, giving you flexibility in various lighting conditions.
The H55’s smaller sensor means it struggles beyond its native ISO 3200, with noticeable noise creeping in much earlier. Also, it shoots only JPEGs - no RAW support - which limits post-processing latitude.
If crisp, detailed images with flexibility in diverse lighting situations matter to you, the NX20's sensor is a big advantage. The H55 is more of a casual shooter’s companion, best for daylight scenarios.
LCD Screens and Viewfinder Experience: Framing and Reviewing Your Shots
Next up, user interface for composing and reviewing your images.
The NX20 features a 3” fully articulated OLED screen at 614K dots - that’s vivid, crisp, and viewable from all angles. This articulating design is superb for shooting subjects at different heights or angles, including selfies (Samsung marked it as selfie-friendly). The OLED tech yields deeper blacks and better color accuracy versus typical LCDs.
Sony’s H55 offers a fixed 3” LCD with 230K dots, a much more basic screen. It’s neither very bright nor detailed, making focusing and reviewing in bright light challenging. Lacking a viewfinder, you’re tethered to this fixed screen.
In practical terms: For street photography, landscapes, portraiture where composition flexibility matters, the NX20’s screen is a delight. For quick snapshots or travel, the H55’s screen suffices but is less inspiring.
Autofocus, Shooting Speed, and Burst Modes: Catching the Decisive Moment
If you photograph moving subjects - sports, wildlife, kids - the AF system and frame rate are critical.
The NX20 has a contrast-detection AF system with 15 focus points including face detection. It supports single, continuous autofocus but lacks advanced tracking or eye/animal detection AF technology developed later in the decade.
Burst speed on the NX20 hits up to 8 fps, allowing decent action capture with precise control for exposure and focus.
The H55, although it has 9 contrast-detection points, offers only single AF and a 10 fps burst mode. However, keep in mind the fixed lens and sensor limitations reduce image quality and buffer depth during continuous shooting.
For wildlife or sports, the NX20’s larger sensor coupled with faster burst and face detection is preferable, though it’s no flagship tracking hero. The H55’s burst speed is higher on paper but less usable for sharp action images due to slower AF and smaller sensor.
Lens Ecosystem and Versatility: Can the Camera Grow with You?
A significant upside of mirrorless systems is lens interchangeability. Samsung’s NX mount has 32 lenses available spanning wide-angle, telephoto, primes, and macro options.
The Sony H55’s fixed lens covers a 25-250mm equivalent zoom range with a maximum aperture of f/3.5-5.5. That’s versatile for casual shooting but locked in design and optical quality. No option for upgrades or attaching faster, specialized optics.
If you’re someone who appreciates upgrading lenses for specific needs - portrait bokeh, macro close-ups, sports telephotos - the NX20 offers a scalable investment path. The H55 is a grab-and-go camera, excellent for convenience but not long-term versatility.
Specialized Photography Use Cases - How Do They Perform Across Genres?
Let me break down performance tailored by genre and shooting scenario.
Portrait Photography
Skin tones rendered naturally by the NX20’s sensor and tonal gradation blow away the H55’s flatter JPEG outputs. Thanks to interchangeable lenses, you can opt for bright primes (like a 30mm f/1.4) to create creamy bokeh, isolating your subjects beautifully.
The H55’s zoom range lacks the shallow depth-of-field character and face detection autofocus, so portraits look flatter and less dimensional.
Landscape Photography
With 20MP detail, 12.9 EV dynamic range, and an articulating OLED display, the NX20 excels at landscapes, capturing subtle shadows and highlights. Add weather sealing and tripod compatibility, and you have a serious landscape tool.
The H55, with small sensor and limited resolution, can’t deliver the same fine details or shadow recovery, making it best for casual daytime sweeps rather than professional results.
Wildlife and Sports Photography
Thanks to faster 8 fps continuous shooting and face detection AF, the NX20 can manage casual wildlife or sports. Coupled with telephoto zoom lenses (available in NX mount), it’s flexible.
The H55 is handicapped by slower AF, fixed zoom, and smaller sensor. Its 10 fps burst speed is impressive, but continuous autofocus isn’t, often yielding missed focus at distance or for fast subjects.
Street Photography
Here’s where the H55’s compact form factor and silence shine. The small footprint and relative discretion allow candid shots without drawing attention. The NX20, while larger, has a quiet electronic shutter option (although limited in speed), making it usable too but less pocketable.
Macro Photography
Samsung’s NX20 supports macro lenses with precise manual focus - key for close-up detail. The larger sensor captures texture and intricate detail richly. The H55 offers a 5cm close-focus range, decent for casual macros but lacks manual focus and peerless detail capture.
Night and Astro Photography
The NX20’s higher ISO ceiling (up to 12,800) and larger pixel pitch greatly aid low-light and star photography, especially paired with fast prime lenses and tripod use. The smaller sensor and max ISO of 3200 on the H55 struggle in dim conditions, often resulting in noise and softer images.
Video Capabilities
Samsung’s NX20 shoots full HD 1080p at up to 30fps using H.264/MPEG-4 formats, with a microphone jack for external audio and built-in flash for fill light. The articulated screen helps framing video creatively.
The Sony H55 maxes out at 720p HD video at 30fps without external microphone support. Optical image stabilization helps handheld video but lacks resolution and connectivity features the NX20 offers.
Travel Photography
The H55 wins points for being pocket-friendly, lightweight, and simple to use on the go. It fits into a jacket or small bag without a fuss.
The NX20 is heavier and needs extra lenses for full versatility but offers superior image quality and creative options - ideal for serious travel photographers who prioritize image quality over minimalism.
Professional Work
For pro workflows, the NX20 supports RAW files, manual exposure, external flash control, and tethering via USB - essentials for studio or commercial work.
The H55's JPEG-only capture and basic exposure controls target casual users, not professional needs.
Build Quality and Weather Resistance
Neither camera offers extensive weather sealing, though the NX20 has a more robust build given its category. The lighter H55 is more fragile and better sheltered from elements.
For rough conditions, the NX20 fares better but neither is ideal for harsh environments compared to weatherized pro models.
Battery Life, Storage, and Connectivity
The NX20 uses Samsung’s BP1130 battery pack, rated at about 360 shots - the kind of stamina you’d expect from an advanced mirrorless system.
Sony’s H55 battery specifics are vague, but smaller compacts generally deliver fewer usable shots per charge.
Both camera models rely on a single card slot. The NX20 supports SD/SDHC/SDXC cards, whereas H55 handles multiple card formats including Memory Stick and SD variants, favorable for backward compatibility.
Connectivity on the NX20 includes built-in Wi-Fi, HDMI out for live video output, and USB 2.0. The H55 lacks wireless features (no Wi-Fi, Bluetooth, or NFC) and HDMI output, limiting its connectivity and file transfer flexibility.
Price-to-Performance Ratio: What Are You Really Paying For?
At launch, the NX20 MSRP was around $1100 for the body alone. Today, you might find used or refurbished models near or below this, but keep in mind the NX20 delivers a robust feature set matching its mid-advanced mirrorless class.
The Sony H55 went for about $235, making it far more affordable but aimed squarely at beginner or casual users.
If budget is tight and you want a versatile compact superzoom, the H55 offers reasonable value for travel or kids’ snapshots. But for quality, expandability, and professional features, the NX20 justifies the higher price with hands-down better performance and flexibility.
Visual Performance: Sample Images from Both Cameras
I captured these scenes under similar conditions to give you tangible evidence of their output:
Observe the richer detail and accurate tones from the NX20 images, especially in shadow areas and color rendition. The H55 photos appear softer and flatter, with less dynamic range.
Overall Performance and Ratings Summary
To wrap up my testing and data synthesis, here are the overall scores:
The NX20 scores a respectable 75 on DxOmark’s scale, bolstered by strong sensor performance and image quality. The H55 is untested on this scale but based on specs and experience, below the NX20 significantly.
Genre-Specific Camera Suitability and Scores
Breaking it down by photography genres:
The NX20 leads across nearly all categories except street and travel - where the H55’s portability balances the scales. For video, low light, and professional demands, NX20 is head and shoulders above. The H55 remains a solid casual option with its zoom range and ease of use.
Final Thoughts – Which One Should You Buy?
So, who is the Samsung NX20 for? If you’re a photography enthusiast or professional wanting superior image quality, manual controls, interchangeable lenses, and serious flexibility, the NX20 remains a worthy investment despite its age. Its APS-C sensor, articulating OLED display, and solid build are assets you won’t find in a compact.
If you’re a casual shooter, frequent traveler, or on a tight budget who prioritizes lightweight gear and simple operation over technical excellence, the Sony H55 can still serve you well.
My recommendation: For any serious photography task - portraits, landscapes, wildlife, video, or professional work - go with the NX20. For fun snapshots, vacations, or as a backup, the H55 is a pocketable companion.
Dear reader: the ideal camera is the one that matches your personal shooting style and goals. Consider how you prioritize image quality, control, portability, and budget - and use this comparison to guide your choice. Happy shooting!
