Choosing Between the Samsung NX300 and Sony A700: A Real-World Camera Showdown

As someone who’s spent over 15 years testing cameras across countless photography disciplines - from studio portraits to rugged wildlife shoots - I’ve encountered all manner of gear vying for photographers’ attention. Today, I’m sharing an in-depth, no-nonsense comparison of two distinct cameras: Samsung’s mirrorless NX300 and Sony’s advanced DSLR A700. With years between their releases and different design philosophies, they offer a unique study in contrasts that can help you pinpoint which fits your photography journey best.

I’ve shot thousands of images with both cameras in a variety of settings, using professional lenses and testing their capabilities under controlled and spontaneous circumstances. Here’s my experience, broken down into clear, practical sections covering everything from ergonomics to genre-specific performance, so you can make an informed choice.

First Impressions: Size, Build, and Handling

When I first handled the Samsung NX300 and Sony A700 side by side, their physical differences were immediately apparent.

The NX300 is a rangefinder-style mirrorless camera that’s compact - measuring 122x64x41 mm and weighing just 331 grams. It fits snugly in smaller hands and is highly portable, perfect for photographers who prioritize mobility. The body is sleek with a minimalist aesthetic and a clearly modern flair.

In contrast, the Sony A700 is an older yet sturdier mid-size DSLR with dimensions of 142x105x80 mm and tipping the scales at a hefty 768 grams. The more substantial grip and overall heft convey durability and enable a firm hold, especially beneficial for heavier lenses during extended shoots. Its magnesium alloy frame and environmental sealing make it a rugged tool built to last, something I’ve appreciated when shooting in challenging outdoor conditions.

The NX300’s streamlined top plate minimizes dials and buttons - ideal for beginners or those focusing on ease of use - while the A700’s traditional DSLR controls offer ample dedicated buttons and a mode dial for swift manual adjustments, suiting photographers who prefer tactile feedback and quick access to settings.

Ergonomic takeaway: If portability and discreetness appeal to you, the NX300 shines. For those wanting a commanding grip and robust build, especially for professional or outdoor use, the A700 is a winner.

Sensor Tech and Image Quality: Old vs. New CMOS Designs

At the heart of any camera is its sensor, directly influencing image quality and creative possibilities.

Both cameras house APS-C sized CMOS sensors (~23.5x15.7 mm), but the NX300’s 20 MP resolution takes a step up from the A700’s 12 MP. This resolution difference means the NX300 can capture finer detail, vital for large prints or cropping flexibility. Samsung’s DRIMe IV image processor aids in delivering clean images with punchy color rendition and responsiveness.

DxOMark data confirm the NX300's edge in key metrics: a higher overall score (76 vs. 66 for the A700), greater dynamic range (12.7 vs. 11.9 stops), improved color depth (23.6 vs. 22.3 bits), and better low-light sensitivity (ISO 942 vs. 581). In my practical tests, this corresponds to cleaner shadows, richer skin tones, and more usable detail preserved in highlights during bright landscapes.

The A700, despite its age, is no slouch. Its sensor performs well for a 2007-era release, particularly in good lighting conditions, and benefits from in-body sensor-shift stabilization to counteract camera shake - a major plus that the NX300 lacks. In lower light, however, noise becomes more apparent as ISO climbs past 1600, whereas the NX300 maintains smoother tonal gradations up to higher sensitivities.

LCD and User Interface: The Window to Your Creativity

Shooting experience hinges greatly on image preview and menu navigation.

The NX300 boasts a 3.3-inch tilting AMOLED touchscreen with 768k dots. The richness of the OLED technology results in vivid, high-contrast previews even under daylight glare. The touchscreen interface makes focusing and menu navigation highly intuitive - especially appreciated during quick on-the-fly framing or in street photography.

Conversely, the Sony A700 offers a fixed 3-inch TFT display with 920k dots - higher pixel count but less dynamic range and no touchscreen. There’s a dependable optical pentaprism viewfinder covering approximately 95% of the frame with 0.6x magnification, which I frequently prefer for its natural, lag-free viewing, especially during fast-paced action like sports or wildlife.

User interface insight: The NX300 caters well to modern, tactile shooting habits and those transitioning from compact cameras, whereas the A700 appeals to traditionalists who rely on optical viewfinders and physical controls.

Autofocus Systems: Speed, Precision, and Tracking

Autofocus can make or break a shoot, and these cameras belong to very different AF generations.

The NX300 employs a hybrid autofocus system combining 247 phase-detection points with contrast-detection, delivering fast, confident locking even in live view or video modes. Its face detection further enhances portrait shooting by accurately tracking eyes and faces. I found the NX300’s AF especially helpful in street and portrait sessions with moving subjects.

The Sony A700 uses a 11-point phase-detection AF system, common for mid-range DSLRs of its time. While reliable under well-lit conditions, it lacks continuous AF tracking capabilities for moving subjects and none of the newer face detection automation. In low light, the A700’s AF hunting is more noticeable compared to the NX300’s hybrid system.

Given this, the NX300 has the clear advantage for wildlife and sports shooters needing rapid acquisition and tracking, while the A700’s AF serves best in structured, controlled environments like studio or landscape.

Shooting Speed and Buffer Capacity

For photographers capturing fleeting moments, continuous shooting speed and buffer depth is paramount.

Samsung’s NX300 delivers up to 9 frames per second (fps), a remarkable rate typically reserved for pro-level bodies - coupled with a buffer that accommodates 22 RAW frames. This speed is impressive for an entry-level mirrorless, great for sparring fighters in a boxing match or birds in flight.

The Sony A700 tops out at 5 fps, which was respectable in its era and sufficient for many sports and action scenarios but less competitive today. Its buffer fills faster, limiting burst duration for RAW images.

Fast shooters will find the NX300 more flexible here; casual shooters may find both models adequate depending on subject matter.

Lens Ecosystem Compatibility: The Heart of Creative Potential

Lens availability and quality have a profound impact on fulfilling photographic vision.

Samsung’s NX mount is proprietary, offering 32 lenses including primes, zooms, and speciality optics like macro. While this is a decent selection, the ecosystem is far smaller than Sony’s and somewhat limited in third-party support - often requiring adapters to use popular lenses.

Sony’s Alpha (Minolta A-mount) benefits from a far more extensive collection - more than 140 lenses including legendary Minolta glass, Sony’s own modern G-series, and third-party manufacturers. This broad compatibility is priceless for professionals and hobbyists looking for specific focal lengths, apertures, or optical characteristics. The A700’s in-body image stabilization also complements any lens in use, enhancing handheld versatility.

Durability and Weather Resistance: Cameras That Work Harder

Sony’s A700 distinguishes itself with environmental sealing, designed to resist dust and moisture intrusion - a feature I’ve relied upon shooting in foggy, rainy conditions and dusty trails.

Conversely, the NX300 lacks any official weather sealing, so while it’s robust for urban and travel shooting, I would hesitate to take it into inclement or extreme conditions without protective covers.

If you often work outdoors where weather is unpredictable, the A700’s sealed body is a major advantage.

Battery Life and Storage Flexibility

The NX300 manages around 330 shots per charge via its BP1130 pack; the compact form factor limits battery size. I found that extended outings require carrying spares or portable chargers.

Sony A700 supports the older NP-FM500H battery that can typically stretch longer on a charge, aided by the absence of power-hungry live view and image stabilization features. Plus, its dual card slots (CompactFlash and Memory Stick) offer fail-safe redundancy for professionals - the NX300 uses a single SD/SDHC/SDXC slot.

Connectivity and Video Features

Samsung invested significantly in modern connectivity - built-in Wi-Fi and NFC for effortless sharing, plus HDMI and USB 2.0 ports. The NX300 delivers Full HD 1080p video recording with decent codec options, making it a versatile hybrid for casual videographers. Though there’s no external microphone input, the quality in good lighting is usable for YouTube creators or family moments.

The Sony A700, released pre-video era for DSLRs, offers no movie mode and lacks wireless features entirely. It’s a pure photography tool.
