Samsung NX300M vs Sony Cyber-shot DSC-H55: An Expert Comparison for Serious Photographers and Enthusiasts

Choosing your next camera isn’t just about brand loyalty or flashy specifications on a spec sheet - it’s about how the gear performs in the real world, how it fits your photographic style, and the compromises you can live with. Having spent over 15 years rigorously testing hundreds of cameras, I know that any candid comparison must dig beneath the surface. So today, we're going head-to-head with two quite different camera models from Samsung and Sony: the Samsung NX300M, an entry-level mirrorless from 2013, and the Sony Cyber-shot DSC-H55, a small sensor compact released in 2010.

They might seem like apples and oranges - a dedicated interchangeable lens mirrorless versus a long-zoom compact - but this contrast is precisely what makes the comparison interesting. In this article, I’ll walk you through sensor performance, autofocus, handling, and strengths across major photography genres - portraits, landscapes, wildlife, sports, and more. Whether you’re on a tight budget looking for versatility or after tailored image quality in a mirrorless system, keep reading. By the end, you’ll know which camera truly suits your style and workflow.

The Physical Feel: Size, Ergonomics, and Controls

Before we pick apart technical specs, let’s talk about how these cameras feel and work in your hands - because trust me, ergonomics greatly influence the quality of your shooting experience. Here’s a size comparison between the two:

Samsung NX300M shows off the classic rangefinder-style mirrorless body, relatively compact but definitely bigger and heavier (331g) than the Sony. Measuring 122x64x41 mm, it has a solid, grippable feel, lending confidence especially during longer shoots. Its magnesium alloy frame (though not weather-sealed) has a sturdy yet refined build. You get a thoughtfully laid-out control scheme, including dedicated dials for shutter speed and exposure compensation, which I appreciate when shooting manually.

By contrast, the Sony H55 is a pocket-friendly compact weighing just 200g and fitting easily in one hand or a jacket pocket (103x58x29 mm). This ultra-portability is fantastic for casual travel, day-to-day street photography, or a quick grab-and-go scenario. However, the tiny controls and fixed lens can feel limiting if you want full creative flexibility.

Looking from the top view, you can see the Samsung’s more advanced control layout versus the simpler Sony:

Here, the NX300M impresses with its dual command dials and easy access to shooting modes. The Sony offers basic controls, focused on point-and-shoot ease.

Bottom Line: If handling and manual control interest you, the Samsung feels more like a fully-featured camera for serious photography. But the Sony leans into portability and simplicity.

Sensor Size and Image Quality: The Heart of the Matter

Image quality starts with the sensor - its size, technology, and resolution. The Samsung NX300M boasts a large APS-C CMOS sensor (23.5x15.7mm), common in many mid-level DSLRs and mirrorless bodies, while the Sony H55 uses a much smaller 1/2.3" CCD sensor (6.17x4.55mm).

Here’s the sensor size comparison to visually drive home that contrast:

Technically, the Samsung’s sensor area (about 369 mm²) eclipses the Sony’s tiny 28 mm², meaning it collects far more light - a crucial factor for image quality, noise performance, and depth of field control. The NX300M’s 20 megapixels offer a pleasant balance between resolution and noise control. The Sony’s 14 megapixels squeeze into a small sensor, resulting in tighter pixel pitch and more noise at high ISOs.

Over years of hands-on testing cameras with similar sensor setups, I can confidently say that in real-world shooting, the Samsung NX300M delivers finer details, enhanced dynamic range, and cleaner images in low light. The Sony H55’s sensor struggles beyond ISO 400, producing visibly softer and noisier JPEGs due to limited ISO range (max 3200) and smaller photosites.

Both cameras apply an anti-aliasing filter, slightly softening images to combat moiré, but the NX300M’s superior sensor provides better image fidelity, especially for printing or cropping.

What you’ll notice on portraits, landscapes, and high-res shots with the Samsung is that fine texture and tonal depth stand out - very gratifying to critical eyes.

Display and Interface: Putting Controls at Your Fingertips

The live preview and menu navigation can either make or break your shooting flow. Let’s compare the rear screens:

The Samsung NX300M offers a 3.3-inch, 768k-dot Active Matrix OLED tilting touchscreen - a standout feature even today. This delivers bright, vibrant colors, deep blacks, and excellent viewing angles outdoors. The tilting mechanism aids low or high-angle compositions. Touch responsiveness for autofocus and menu navigation enhances usability.

The Sony H55 has a smaller 3.0-inch, 230k-dot fixed LCD, noticeably dimmer and coarse in pixel density. It lacks touch input and tilting, hampering compositional flexibility and quick focusing adjustments.

While the Samsung interface was sometimes criticized for somewhat complex menus, once you get used to it, it feels powerful and intuitive with tactile feedback.

Autofocus Systems: Speed, Accuracy, and Tracking

If you crave fast, accurate autofocus, the choice here is clear - the technology gap just widens beyond the years these cameras were launched. The Samsung NX300M employs a hybrid system combining contrast and phase-detection autofocus across 247 points, which was cutting-edge for its class in 2013.

This system supports face detection, continuous AF, and even multi-area tracking, yielding sharp, consistent focus on moving subjects - crucial for wildlife and sports.

The Sony H55, in contrast, only uses contrast detection AF with merely 9 points. No face or eye detection, no tracking autofocus. It locks focus slower and hunts more, which can frustrate rapid-paced shooting scenarios.

From my practical tests, when capturing action or spontaneous moments, the Samsung’s AF confidence and speed are much better, reducing missed shots.

Lens Ecosystem and Compatibility: Creative Freedom Matters

The NX300M leverages the Samsung NX mount system, which, while niche, had about 32 lenses available covering focal lengths from ultra-wide to long telephoto, including options for primes, zooms, macros, and fast apertures. This was an uncommon offering among beginner mirrorless systems at the time.

That means you can adapt your gear for portraits using a fast f/1.4 prime, landscapes with a sharp wide-angle zoom, or wildlife with telephoto lenses - enabling true creative control.

The Sony H55’s fixed 25-250mm f/3.5-5.5 lens is versatile for general photography but has significant limitations in depth-of-field control, low-light performance, and optical quality compared to dedicated primes or pro zooms.

If building a lens collection appeals to you - and it usually should for serious photographers - the Samsung opens doors that this compact does not.

Handling Across Photography Genres

Let me break down how each camera performs in specific photographic situations I often test:

Portrait Photography

• Samsung NX300M: The APS-C sensor's larger size allows for beautiful subject-background separation with pleasing bokeh. The 247 focus points and face detection provide accurate eye focus. Colors are natural and skin tones render warmly, especially using manual white balance. The tilting OLED screen helps secure difficult angles.
• Sony H55: Portraits are serviceable but look flat due to the small sensor - hard to get creamy background blur. Face detection may be missing, making focusing on eyes hit-or-miss. Lower resolution and higher noise at wider apertures reduce detail in hair and textures.

Winner: Samsung for depth and focus precision.

Landscape Photography

• Samsung NX300M: Delivers high-resolution, wide dynamic range images with good shadow detail, ideal for stitching panoramas or large prints. No weather sealing, so add caution outdoors. The extensive lens options, including sharp wide-angle primes and ultrawides, give flexibility.
• Sony H55: Limited by smaller sensor and fixed lens. Dynamic range is compressed; highlights clip easily on bright skies. Optics can softening edges, especially at extreme zooms, hindering landscape with fine detail.

Winner: Samsung for detail and flexibility.

Wildlife Photography

• Samsung NX300M: Thanks to rapid continuous shooting (9 fps) and AF tracking, it keeps pace with moving animals. The possibility of pairing with long telephotos compensates for reach.
• Sony H55: The massive 10x zoom lens is handy for distant subjects but slow autofocus and lack of continuous AF make capturing action tricky.

Winner: Samsung for autofocus and optical adaptability.

Sports Photography

• Samsung NX300M: Burst mode and tracking AF allow for decent action capture. The exposure controls help manage challenging lighting in indoor venues.
• Sony H55: The slow max shutter speed (1/1600s), limited ISO range, and delay in focus chasing render it less capable.

Winner: Samsung hands down.

Street Photography

• Samsung NX300M: Bulkier, but the tilting screen enables candid low-angle shots. Silent electronic shutter missing though, so you might catch some shutter noise.
• Sony H55: Small size and zoom flexibility are perks on the street, letting you shoot unobtrusively at a distance.

Winner: Sony if discretion is priority, Samsung for image quality.
