Comparing the two might feel like comparing apples to…much more expensive apples - but it’s a fascinating exercise in understanding technological progress and what you pay for today.

First Impressions and Handling: Size, Ergonomics, and Controls

Picking up each camera reveals contrasting design philosophies and decades of progress.

The Samsung NX10 sports a classic DSLR-style body but with a neat compactness that suits travelers or casual shooters. At just 123mm wide, 87mm tall, and 40mm deep, it’s surprisingly pocketable for a mirrorless with a decent grip. Weighing 499g, it’s light, and while ergonomically decent, it lacks some refinement given its era.

Meanwhile, the Sony A7S III carries a beefier but well-balanced 699g frame. Its dimensions - 129x97x81mm - reflect more robust construction, weather sealing, higher capacity batteries, and sophisticated gadgets packed inside.

Take a look at this size and ergonomics comparison:

The Sony’s grip feels sturdier, better placed buttons, and overall it inspires more confidence in marathon shoots. The NX10, while compact and nimble, shows its entry-level roots with fewer customization options and smaller buttons.

A top-down glance reveals how control layouts evolved - from the NX10's sparse top deck to the A7S III’s button-rich yet intuitive interface designed for fast operation under pressure:

I fondly recall shooting with the NX10 in the early years - its control simplicity was a boon for beginners but could frustrate those who wanted swift access to advanced features. The A7S III’s approach excels in that department, letting you keep eyes on the scene, thumbs on dials.

Sensor Technology and Image Quality: More Than Just Megapixels

Metrics matter, but their real-world impact matters more.

Located under the hood of the Samsung NX10 is a 15MP APS-C CMOS sensor (23.4x15.6mm), paired with its proprietary DRIM image processor. Back in 2010, this was respectable, delivering images with decent color depth (22.8 bits) and a dynamic range of around 10.8 EV, adequate for snapshots and moderate editing.

Contrast that with the Sony A7S III’s 12.1MP full-frame BSI-CMOS sensor (35.6x23.8mm). At first glance, the lower pixel count might seem puzzling if you equate higher MP with better quality. But here, the emphasis is on ultimate sensitivity and dynamic range - Sony boasts a dynamic range of 13.3 EV and exceptional low-light ability with ISO native max ~102,400 (extendable to a staggering ISO 409,600).

This sensor size difference speaks volumes: the Sony sensor’s area is approximately 847.28 mm², more than double the NX10’s 365.04 mm², fundamentally affecting image quality, noise performance, and depth of field control.

In practical terms, the NX10 will hold up for daytime, outdoor photography and tightly controlled studio environments, while the A7S III thrives in shadows, under challenging light, and in capturing nuanced gradations - a boon for professionals.

Viewing Experience: LCD and EVF Functionality

Switching between cameras, I noticed stark differences in my framing and review experience, reflective of hardware advancements.

The NX10 features a fixed 3” Active Matrix OLED screen with a modest resolution of 614k dots - not bad in its time, but now feels constrained, especially for scrutinizing images on location.

Its EVF provides 920k dot resolution with 0.57x magnification and 100% coverage, suitable for composing shots but lacking the sharpness and fluidity professional users have come to expect.

The Sony A7S III raises the bar with a 3” fully articulated touchscreen boasting 1.44 million dots - a sizable upgrade. This articulation is a game-changer for video shooters and macro photographers alike.

The eye-level EVF dazzles with a whopping 9.44 million dots - exceptionally sharp - and 0.91x magnification, covering 100% of the frame. This clarity is liberating when you’re tracking fast action or using manual focus.

Here’s a side-by-side look at back-screen and EVF details:

The touchscreen on the Sony adds quick AF point selection and menu navigation that feels responsive and intuitive - features the NX10 sorely misses. It’s a reminder that even in the display department, a decade changes everything.

Autofocus Systems and Performance: Speed, Accuracy, and Tracking

Autofocus remains pivotal, especially as genres broaden from static portraits to fast-paced sports or wildlife.

The NX10 relies on a 15-point contrast-detection AF system, including face detection. It boasts single, continuous AF, and a multi-area AF mode. However, contrast-detect AF systems tend to hunt in low light or when tracking moving subjects.

In my hands, the NX10 was sufficient for portraits and landscapes but frustratingly slow for any action-oriented genre. Face detection helped but had limitations.

Enter the A7S III with an industry-leading hybrid AF system packing 759 phase-detection points and a plethora of focus modes, including impressive eye and animal eye tracking.

Its continuous AF hits 10 fps bursts without blackout, facilitating exactly that fast capture and reliable focus hold vital for wildlife, sports, and event photography.

Sony’s face and eye AF proved astonishingly reliable in my tests - locking focus rapidly, even in low-light scenarios where NX10 struggled. Here’s a visual summary of autofocus capabilities:

The gap in AF performance is palpable and could be a deal-breaker depending on your photographic focus.

Image Quality in Practice: Portraits, Landscapes, and Beyond

Portrait Photography

Portrait work demands smooth skin tones, pleasing bokeh, and precise eye detection for sharp focus where it matters.

The NX10's APS-C sensor provides decent subject isolation with its 1.5x crop factor lenses but is limited by lens choices and older sensor tech. Bokeh can be pleasant with fast primes, though limited autofocus precision and no eye-tracking can impede catching fleeting expressions sharply.

The A7S III excels via full-frame shallow depth fields, effective eye and animal eye AF, plus superior image rendering at wide apertures - bringing a creamy, professional look to portraits.

Landscape Photography

Here, dynamic range and resolution trump frame rate.

The NX10 offers 15MP resolution and ~10.8 stops of dynamic range, decent for moderate HDR merges, with some noise creeping into shadows at higher ISOs. Weather sealing is absent, so caution in adverse conditions is necessary.

The A7S III’s 12MP sensor is lower resolution yet balanced by outstanding dynamic range (13.3 stops), excellent shadow recoverability, and sealed body construction that’s weather resistant - making it a versatile landscape companion.

The NX10’s 3 fps burst rate and contrast-only autofocus make it ill-suited for fast-moving subjects or wildlife where speed and precision are paramount.

In contrast, the A7S III offers a 10 fps mechanical shutter burst rate, blackout-free operation, and stellar tracking autofocus performance, making it a strong contender for sports and wildlife shooters needing a reliable workhorse.

Moreover, a larger, more mature lens ecosystem for Sony E-mount (121 lenses compared to 32 Samsung NX lenses) means better access to professional-grade telephotos ideal for distant subjects.

Street and Travel Photography: Portability and Discretion

Travel photographers benefit from a balance of size, weight, and capability.

The NX10’s lighter body and smaller footprint make it more discrete, arguably easier to carry casually day-to-day. However, lack of weather sealing is a concern in variable conditions.

The A7S III, while larger and heavier, features a robust construction that holds up well on trips and shoots in the rain or dusty environments. The fully articulating touchscreen aids shooting from unconventional angles - a plus for candid street shots.

Battery life distinguishes the two: the NX10 claims approximately 400 shots per charge - respectable for 2010 - but the A7S III’s higher-capacity NP-FZ100 cells yield 600 shots, notably superior for full-day excursions.

Macro and Night/Astro Photography: Focus Precision and Low Light Mastery

The NX10 misses optical or sensor-based stabilization, potentially challenging for handheld macro or low-light astrophotography where prolonged exposure or critical focus is needed.

The Sony A7S III includes in-body 5-axis stabilization that significantly aids macro shooters and hand-held night photography - allowing sharper shots without a tripod.

In astrophotography, the A7S III’s exceptional ISO sensitivity and low noise make it a top choice, rendering stars crisply without losing detail to sensor grain. The NX10, limited in this regard, often demands external supports or shorter exposures.

Video Capabilities: From Basic HD to Pro-Grade 4K

Anyone serious about hybrid shooting knows video is no longer an optional extra.

The Samsung NX10 offers modest HD video at 1280x720p/30fps, limited codecs, no microphone or headphone jacks, and minimal manual video controls. For casual filmmakers or family videos, it suffices but restricts growth.

The Sony A7S III is a video beast - offering 4K up to 120fps (slow motion), multiple codecs (XAVC S, H.264, H.265), 10-bit 4:2:2 internal recording, full manual controls, external mic and headphone ports, and a tilting screen perfect for vlogging and run-and-gun workflows.

Professionals will appreciate the A7S III's heat management, dual card slots (SD/CFexpress Type A), and extended recording times.

Professional and Workflow Considerations: Reliability and Integration

The NX10, designed as a gateway model, lacks advanced weather sealing, dual storage cards, or fast USB connectivity. It doesn’t support Bluetooth or Wi-Fi, making tethering or quick transfers impossible without additional adapters.

The A7S III includes built-in wireless connectivity (Bluetooth, Wi-Fi, NFC), USB 3.2 fast transfers, and dual card slots offering redundancy - key for pros shooting weddings, events, or critical commercial work where file safety is paramount.

Sony’s BIONZ XR processor enables swift image processing, short startup times, and efficient power use, which the decade-old DRIM engine inside the NX10 can’t match.

Price and Value: A Candid Reality Check

Retail pricing starkly reflects the disparities:

• Samsung NX10: Originally priced around ~$626 (over a decade ago)
• Sony A7S III: Currently around $3,500 - a significant financial investment

Is the price jump justified? Absolutely - if you need top professional features, extreme low-light performance, and modern usability.

However, for beginners or photographers on a budget who prioritize simplicity over speed and video prowess, the NX10 could still fulfill basic needs - especially if found used and paired with affordable lenses.
