Samsung NX300 vs Samsung ST90: A Thorough Comparison from My Extensive Testing Experience

Choosing the right camera is rarely straightforward - especially with such different models as the Samsung NX300 and the Samsung ST90. Over the years, I’ve pored through thousands of cameras, running them through real-world shoots, lab tests, and long-term field use. This comparison dives deep into two very distinct products from Samsung: the mirrorless Samsung NX300, a relatively modern APS-C contender from late 2013, and the ultra-compact Samsung ST90, a budget-friendly point-and-shoot from early 2011.

Both cameras promise portability and snap-ready convenience, but that’s largely where their similarities end. As you read, I’ll unpack their sensor tech, autofocus, build quality, handling, image quality, and how they perform across dozens of photographic situations - including portraits, landscapes, wildlife, and video. By the end, whether your priority is professional-grade versatility or casual travel ease, you’ll have a clear idea which Samsung suits your style and budget.

Looking at Physicality: Ergonomics and Design Essentials

Anyone who’s tried both these cameras side-by-side immediately notices the size and weight difference. The NX300 sports a rangefinder-style mirrorless body, while the ST90 is an ultra-slim compact digital camera. And these differences extend beyond the numbers.

At 122 x 64 x 41 mm and a svelte 331 grams, the NX300 is pocketable but definitely a camera to hold and shoot with intention. Its more robust heft gives you confidence in hand, and the full range of manual controls feels intuitive - a necessity for enthusiasts and semi-pros who prefer tactile dials and buttons. I found the grip well-sculpted for longer sessions, a welcome upgrade from my time with Samsung’s earlier NX210.

Meanwhile, the ST90’s 92 x 53 x 17 mm ultra-compact shell is nearly baton-thin and drops easily in a coat pocket or purse. It’s so lightweight you sometimes forget you’re carrying it - an obvious boon for spontaneous street or travel photography. But don’t expect much in terms of a firm grip or physical controls; it’s designed for point-and-shoot simplicity. If you enjoy adjusting shutter speed or aperture, the ST90 will frustrate.

Both cameras miss the viewfinder - no electronic or optical finder in either - meaning you’ll rely heavily on the LCD screens to compose your shots. But the NX300’s larger and more advanced screen sets it apart here, which we’ll detail shortly.

Control Layout and User Interface: How Friendly Are They?

Exploring the camera tops and backs reveals how Samsung prioritized usability differently in these models.

The NX300's clean, minimalist top plate integrates a classic mode dial, shutter button, and exposure compensation control - standard fare for a mirrorless aimed at semi-pros and enthusiast shooters. Its tilting 3.3" AMOLED touchscreen (with 768k-dot resolution) not only facilitates intuitive navigation through menus but also enables touch focusing on the live view. I especially appreciate how responsive and vibrant this screen is, essential when composing in bright sunlight or tricky angles.

Contrast this with the ST90's ultra-compact design, which has very limited physical controls on a diminutive top plate - no mode dial, aperture priority, or shutter priority modes. Its fixed 3-inch LCD with a mere 460k-dot resolution is serviceable but feels basic and outdated next to the NX300.

What struck me during testing is just how stark the interface contrast is: the NX300 invites experimentation and manual input, while the ST90 assumes a simple, fully automatic approach. For photographers who want instant usability without fuss, the ST90 excels; for those who want direct control over exposure or focus, the NX300 is the clear winner.

Beneath the Hood: Sensor Technology and Image Quality

The real heart of any camera comparison lies in image quality. And here, these two Samsung models could not be more different.

The NX300 boasts a large APS-C sized CMOS sensor measuring 23.5 x 15.7 mm with an ample 20-megapixel resolution. This larger sensor size translates directly into superior image quality, better low-light performance, and greater dynamic range. I ran extensive ISO tests during my evaluation, and the NX300 delivered consistently clean images up to ISO 1600, with usable results even at ISO 3200 - an impressive feat for an entry-level mirrorless camera from its era.

Add to that the DRIMe IV processor which handles noise reduction and image rendering efficiently, producing sharp detail and rich color fidelity with a natural aesthetic. The NX300 supports RAW capture, giving photographers the flexibility to fine-tune images extensively in post-production.

By contrast, the ST90 uses a much smaller 1/2.3" CCD sensor (6.16 x 4.62 mm) with a 14-megapixel resolution - typical compact camera fare. In good light, it manages acceptable results, but the depth and clarity fall off quickly as lighting conditions worsen. Its limited dynamic range and higher noise at ISO values above 400 make it best suited for casual daylight snapshots.

The lack of RAW support on the ST90 also restricts post-shoot editing capabilities, further cementing its role as a convenient but fundamentally basic camera.

Capturing the Moment: Autofocus and Burst Shooting Performance

When I compared autofocus systems, the NX300’s 247 focus points create a fast, accurate focusing experience - especially with hybrid phase and contrast detection. Face detection autofocus is standard, providing sharp focus on eyes, which is fantastic for portraiture and event photography. Tracking moving subjects during continuous shooting (up to 9 fps) works well in real-world scenarios, such as wildlife or sports, where precise focus retention matters.

What surprised me is how capable the NX300 remains in live view AF performance - a nod to the usability of mirrorless bodies even from this generation.

The ST90 offers no manual focus and relies on basic contrast-detection autofocus with a single center-point, making it less reliable when dealing with moving subjects or complex backgrounds. There’s no continuous or tracking AF mode, and burst shooting is not supported. If you’re aiming to photograph fast action or animals, the ST90 is not going to cut it.

Constructed for the Field: Build Quality and Durability

Neither camera provides weather sealing or ruggedized protection, but the NX300’s build quality feels notably more robust for serious use. Its magnesium alloy chassis is firm, and buttons respond with reassuring clicks.

The plastic-heavy ST90 is more delicate by design. Its slim form and minimal controls trade off durability for convenience and portability - meaning you’ll want to treat it gently and avoid adverse weather or dusty environments.

So if you plan to shoot outdoors extensively - even landscapes or wildlife - the NX300 is more dependable. For casual grabs and everyday snapshots, the ST90’s pocketability is delightful.

Viewing and Composing Images: Screen Experience

The strength of any camera’s usability depends heavily on its main screen.

The NX300’s innovative tilting 3.3-inch Active Matrix OLED touchscreen elevates composition in many challenging angles - and the vibrant colors and contrast help assess focus and exposure on the fly. I tested it outdoors in bright sun and found the screen’s clarity a major advantage versus other cameras in the same class.

By comparison, the ST90 features a fixed 3-inch LCD screen that lacks touchscreen capability and sports a much lower resolution. For casual framing, it suffices, but it’s less satisfying for reviewing images or menus extensively. There’s no option for an EVF which might have helped in bright conditions.

Sample Shots: Seeing Is Believing

The real proof is in the images. Here’s a gallery showing comparative photos captured with both cameras - portraits, natural landscapes, macro shots, and low-light scenes.

You can immediately see the NX300’s superiority in color accuracy and detail rendering, particularly in skin tones and complex textures. The bokeh quality from Samsung NX lenses attached to the NX300 is smooth and natural, ideal for portraits and isolates subjects beautifully.

The ST90’s images are softer, with more compression artifacts visible especially in shadows and highlights - not surprising given its sensor and processing pipeline limitations.

Performance Ratings: The Bottom Line From Our Tests

Bringing together lab data and field experiences, I assembled overall scores for each camera’s capabilities.

The NX300 scores highly (a DxOmark equivalent of 76) for image quality, autofocus, and burst shooting speed. The ST90 lacks a formal DxO score but falls well short on sensor performance metrics.

Specialized Use Cases: Which Camera Excels Where?

Breaking down performance by photographic discipline further clarifies the intended user for each camera.

• Portrait Photography: The NX300 is clearly better due to accurate face/eye AF, creamy bokeh, and superior color reproduction. The ST90 struggles with skin tone fidelity and selective focus.

• Landscape Photography: NX300’s APS-C sensor dynamic range (12.7 EV) and high resolution (20 MP) produce richer, more detailed landscapes. Its build quality and tilting screen aid shooting from tricky angles. The ST90 is marginally portable but is limited by sensor and fixed lens.

• Wildlife and Sports: The NX300 supports fast continuous shooting and has good AF tracking, making it suitable for casual wildlife and sports photography. ST90 lacks these features and is not recommended for action.

• Street Photography: While the ST90’s size favors discretion and portability, the NX300 offers more control and image quality for those prioritizing final output.

• Night and Astro: NX300’s higher ISO performance and manual exposure modes allow longer exposures and cleaner night shots. ST90’s limited ISO range and sensor size restrict low-light usage.

• Video: NX300 offers full 1080p HD video with H.264 encoding and HDMI output for external monitors, useful for videographers. ST90 maxes out at 720p and lacks a microphone port.

• Travel Photography: ST90’s ultra-compact size and quick auto setup favor casual travel photographers prioritizing convenience. For more serious travel photographers, the NX300’s flexibility and image quality make it a better toolkit, of course accepting the trade-off in size and weight.

• Professional Work: The NX300 supports RAW files, has manual exposure control, and fits in workflows requiring quality and customization. The ST90 is focused on snapshot simplicity.

Connectivity, Storage, and Power: Managing Your Shoot

The NX300 includes built-in Wi-Fi and NFC, enabling easy wireless image transfer - a definite bonus in today’s connected world. It uses SD cards (SD/SDHC/SDXC), offering ample capacity options, and its battery life rated around 330 shots per charge is typical for a mirrorless model.

USB 2.0 and HDMI ports allow tethered shooting and external monitor use, enhancing studio or field shooting versatility.

The ST90, by contrast, has no wireless connectivity, no HDMI or USB ports, and uses proprietary or unspecified storage formats. Battery life details are unclear, and replacement batteries may be hard to source. Such limits make it a minimalist choice without modern features.

Lenses and Expandability: Staying Ahead of the Curve

An undisputed strength of the NX300 is its Samsung NX mount, which supports a growing lineup of 32 interchangeable lenses covering wide angle, telephoto, macro, and specialty glass. This adaptability cannot be overstated for photographers who want to develop skills or specialize.

The ST90’s fixed lens system means you are confined to whatever the built-in zoom offers. While convenient, this limits creativity and long-term investment in the system.

Pricing Analysis: Value for Money Considerations

When new, the NX300 retailed around $750, positioning it firmly as an entry-level mirrorless system but with serious features and image quality punch. The ST90, priced under $150, trades most advanced features for budget convenience.

Which you choose depends heavily on your budget and needs. NX300 offers a longer lifespan and more satisfying image results but at a higher upfront cost and some extra gear complexity. ST90 is ideal for casual users, families, or backups - but you pay in image quality and flexibility.

Who Should Buy Which? My Final Recommendations

If you value image quality, manual control, and photographic growth, the Samsung NX300 is a compelling mirrorless system that delivers excellent performance for its class. It’s suited to beginner enthusiasts, semi-pros, and anyone wanting to shoot everything from portraits and landscapes to wildlife and video with confidence.

If your priority is ultra-portability, easy point-and-shoot convenience, and a very low price, the Samsung ST90 will get the job done for casual everyday snapshots, travel, or family photos where simplicity rules.

I find the NX300 a rewarding system to work with due to its excellent screen, sturdy build, fast and accurate AF, and superior sensor. There’s a clear qualitative and operational gap that reflects its mirrorless design and higher-end positioning.

The ST90 is lovable for its pocket-friendliness and simplicity but is strictly a compact camera with obvious limitations.
