Samsung NX3000 vs. Sony RX10 III: A Deep Dive into Two Distinct Cameras

When it comes to choosing a camera, especially for photography enthusiasts or pros seeking a reliable tool, understanding the real-world capabilities beyond just spec sheets is critical. Today, I'll pit the Samsung NX3000 - a budget-friendly, entry-level mirrorless model from 2014 - against the more recent Sony Cyber-shot RX10 III, a feature-rich, large sensor superzoom camera launched in 2016. Both offer 20-megapixel sensors but cater to very different users and shooting styles.

Having spent years testing thousands of cameras, with hands-on evaluations spanning image quality tests, autofocus trials, ergonomics assessments, and workflow compatibility checks, I’ll walk you through how these two cameras stack up head-to-head. We’ll cover technical details, usability, genre-specific performance, and ultimately, who should consider each camera.

Before getting into the nitty-gritty, let’s scope out their physical design and ergonomics, a key factor as it impacts daily shooting comfort and handling.

First Impressions: Size, Handling, and Design Philosophy

Here’s where the fundamental difference between these two cameras really jumps out. The Samsung NX3000 is lightweight and compact with a rangefinder-style mirrorless body that measures 117 x 66 x 39 mm and weighs only 230 grams. Its minimalist design appeals to casual shooters and content creators who prioritize portability and straightforward operation. The absence of a viewfinder keeps the profile slim, making it easy to toss in a bag or even a large pocket.

By contrast, the Sony RX10 III is a much beefier, SLR-style bridge camera, coming in at 133 x 94 x 127 mm and tipping the scales at 1051 grams. This heft is partly due to its large zoom lens (24-600mm equivalent) and substantial build quality which includes environmental sealing. While not pocketable by any means, it feels impressively solid in the palm and sports an extensive set of controls that will please photographers who want direct access to settings on the fly.

Checking out the top view reinforces these points. The NX3000 keeps control clusters minimal, favoring simplicity, which some may find limiting but also user-friendly. The RX10 III, however, boasts dedicated dials, buttons for ISO, exposure compensation, drive modes, and a top LCD - features often expected in advanced cameras. For users who want a club for every thumb and finger, the RX10 III’s layout will feel like a dream.

Ergonomics Summary:

• Samsung NX3000: Lightweight, minimal controls, ideal for beginners or casual everyday shooting.
• Sony RX10 III: Larger, weather-sealed, multi-dial setup suited for pros or serious enthusiasts who want grip and control.

Inside the Box: Sensor Technology and Image Quality Breakdown

Both cameras sport a 20MP sensor, but here’s where sensor size and design impact image quality heavily. The Samsung NX3000 features a 23.5 x 15.7 mm APS-C CMOS sensor, considered a generous size in mirrorless cameras, enabling excellent light-gathering and dynamic range for an entry-level model.

The Sony RX10 III houses a smaller 1” (13.2 x 8.8 mm) back-illuminated CMOS sensor, about a third the area of the NX3000’s. Despite this, Sony’s BSI sensor design helps it squeeze out respectable noise performance and color depth.

Technical Image Quality Metrics:

• Samsung NX3000 sensor area: 368.95 mm²
• Sony RX10 III sensor area: 116.16 mm²
• DxO Mark Scores (RX10 III only): Overall 70, Color Depth 23.1 bits, Dynamic Range 12.6 EV, Low Light ISO 472

Because DXO Mark hasn’t tested the NX3000, I made comparisons through hands-on shooting, focusing on dynamic range, high-ISO noise, and color reproduction. APS-C generally beats 1” sensors in all three, especially in low light, thanks to its superior pixel pitch.

So, in landscapes with wide dynamic range needs or portraits requiring smooth skin tones, the NX3000 edge is significant. The RX10 III compensates with amazing versatility in focal length, letting you capture distant subjects crisply without changing lenses.

Summary:

• NX3000: Larger APS-C sensor equals better low-light, shallower depth of field (good for portraits), and richer image data.
• RX10 III: Smaller but advanced 1” sensor with outstanding dynamic range for its class; excellent detail in daylight, less forgiving at high ISO.

Viewing and Interface: Display Screens and EVF Comparison

The NX3000 equips a 3” tilting LCD screen with a modest 461k-dot resolution and no electronic viewfinder (EVF). For some, this feels limiting - manual focus and framing sometimes get tricky without a viewfinder, especially in bright daylight.

Sony’s RX10 III ups the ante with a 3” tilting LCD at 1229k dots and a high-res EVF (2359k dots, 0.7x magnification, 100% coverage). This dual-display setup caters to varied shooting styles and lighting conditions - you can compose with your eye to the camera or via the LCD screen comfortably, a big ergonomic plus for long sessions or fast action.

From a workflow perspective, the RX10 III’s EVF eliminates the muck physics of glare during sunny outdoor shoots - a huge advantage for wildlife and sports shooting. The NX3000’s reliance on LCD alone may leave some scratching their heads under bright conditions.

Autofocus Systems and Performance Under Pressure

When it comes to autofocus, both cameras bring contrast-detection AF systems with face detection:

• NX3000: 35 AF points, contrast detect only, face detection present, continuous autofocus possible, no phase detection.
• RX10 III: 25 contrast detect AF points, face detection, continuous AF, no phase detection.

From my testing, the RX10 III’s autofocus is noticeably quicker and more reliable, aided by its Bionz X processor performing real-time calculations faster. The continuous AF mode locks on to subjects and tracks movement well, ideal for wildlife and sports. Meanwhile, the NX3000’s AF can be slower to lock and occasionally hunts in low contrast or backlit scenes.

Though neither camera supports advanced eye-detection or animal eye AF found in newer models, both handle stationary subjects well. For portraits where eye sharpness matters, the RX10 III edges out for precision due to faster acquisition and tracking.

Lens Systems and Optical Versatility

Lens ecosystems define how versatile a camera really is.

The Samsung NX3000 uses the Samsung NX mount, with 32 available lenses ranging from primes to zooms. While not enormous compared to Canon or Nikon ecosystems, it covers most bases at affordable prices. Since this is a mirrorless interchangeable lens camera, you have flexibility to switch lenses tailored to your genre - from wide-angle landscapes to macro photography.

The Sony RX10 III features a fixed 24-600mm (25x) zoom lens with an impressive fast aperture range (F2.4–4.0). The optics here are excellent for a superzoom, handling everything from expansive landscapes at 24mm to close-ups of distant wildlife at 600mm without switching lenses. Plus, the macro focus range reaches as close as 3cm, a benefit for nature and close detail shots.

The tradeoff? You’re limited to this one lens design - with no option for wider apertures or specialized glass. Yet, for traveling light or quick action without juggling gear, the RX10 III does a stellar job.

Build Quality and Environmental Resilience

The RX10 III trumps the NX3000 in build quality without a doubt. It is robust, weather-sealed, and designed to handle light rain and dusty environments - a feature I’ve tested during outdoor shoots with mixed weather. This makes it a reliable companion for serious outdoor photographers and wildlife shooters.

On the flip side, the NX3000 has no weather sealing, making it more vulnerable to elements. It’s best suited for controlled or mild environments rather than rugged adventures.

Burst Shooting and Video Capabilities

For action shooters, continuous shooting speed and video specs often seal the deal.

• NX3000: 5 fps continuous shooting, Full HD 1080p video at 30fps, no microphone/headphone jacks, no image stabilization.
• RX10 III: 14 fps burst rate, 4K UHD (3840 x 2160) video at 30/25/24fps, Full HD up to 60fps, microphone and headphone ports, optical image stabilization included.

The RX10 III shines clearly here. Its burst rate accommodates fast-moving wildlife or sports, coupled with sophisticated video capabilities - essential for hybrid shooters who demand quality footage. The mic jack also enables pro audio capture onsite.

NX3000’s video is serviceable for casual videographers but lacks advanced features or stabilization, thus less suitable for smooth handheld video or demanding productions.

Battery Life and Storage Practicalities

Battery life is often overlooked, yet crucial for extended shoots.

• Samsung NX3000’s rated battery life is approximately 370 shots per charge.
• Sony RX10 III offers roughly 420 shots, which is impressive given the EVF and heavier processing demands.

Both cameras take single battery packs, but the RX10 III’s juice lasts longer likely due to more efficient power management despite its heavier system components.

Storage-wise, the NX3000 supports microSD cards (microSD/HC/XC), which can be slower and more fragile. RX10 III offers SD card slots compatible with high-speed formats, better suited for 4K video and large burst JPEG/RAW files.

Diving Deeper: Genre-Specific Insights

Let’s break down performance through the lenses of different genres - both subjective based on my shooting experiences as well as grounded in specs.

Portraiture

Samsung NX3000 excels at portraits thanks to APS-C sensor providing creamy bokeh and better subject-background separation. Skin tones look natural with its larger sensor and decent color depth, especially using primes available for the NX mount.

RX10 III’s smaller sensor yields less shallow depth of field but the built-in zoom gives framing flexibility. Its fast lens helps in low light, but background blur isn’t as smooth. For casual portraits, it’s fine - but if portraits are your main focus, go NX3000.

Landscape

APS-C’s edge in dynamic range and image resolution (20 MP fully used) means NX3000 offers more latitude for breathtaking landscapes. The lack of weather sealing is a concern though.

RX10 III’s lens versatility (24mm wide angle) makes it handy, but the smaller sensor limits dynamic range and ultimate detail. However, for casual to mid-level landscape shooters wary of hauling multiple lenses, RX10 III still delivers good results.

Wildlife

Here, the RX10 III is a clear winner. Its superzoom range (24-600mm), fast autofocus, decent burst rate, and weather sealing provide a flexible, reliable system to track and shoot animals in often challenging environments.

NX3000’s shorter lens selection requires investing in telephoto lenses and might be slower to react. So serious wildlife shooters will appreciate the RX10 III’s integrated package.

Sports

Fast AF and 14 fps bursts make the RX10 III suitable for sports photography. Plus, its EVF allows accurate tracking under difficult lighting.

The NX3000’s 5 fps and slower AF response make it less ideal; it’s a better fit for posed or static scenes.

Street Photography

The NX3000 is compact, lightweight, and discreet with minimal noise, appealing for street photography purists. Lack of viewfinder can be a drawback in bright streets, though.

RX10 III is bulkier, making it less stealthy. But if you want zoom flexibility and ruggedness on street adventures, it’s still a contender - just less portable.

Macro Photography

RX10 III’s 3cm macro focusing is a big plus and provides impressive close-up sharpness out of the box.

NX3000 can do macro via dedicated lenses, but this means extra investment and gear weight.

Night/Astro Photography

Bigger pixels on APS-C sensor in the NX3000 produce cleaner images at high ISO and excel in long exposures.

RX10 III can handle well-lit night scenes but noise creeps in earlier due to smaller sensor.

Video

RX10 III takes this category by storm with true 4K recording, high frame rates at 1080p, mic/headphone inputs, and image stabilization.

NX3000 is basic 1080p, no audio inputs, and no stabilization - adequate for casual videos but not serious productions.

Travel Photography

For travel, the choice hinges on priorities:

• NX3000’s slim profile and lens interchangeability offer versatility with minimal bulk.
• RX10 III’s all-in-one zoom reduces the need for multiple lenses but adds weight and size.

Battery life slightly favors RX10 III.

Professional Workflows

The RX10 III’s more advanced connectivity, RAW support, and pro-level controls integrate better with professional workflows. The NX3000 is fine for hobbyists but lacks the robustness and options demanded in demanding professional shoots.

Connectivity, Storage, and Extras

Both cameras offer wireless connectivity with built-in Wi-Fi and NFC, enabling easy image transfers. USB 2.0 ports in each limit transfer speeds by today’s standards.

RX10 III adds HDMI and stereo mic/headphone jacks for pro video users; NX3000 only HDMI and lacks audio jacks.

Storage-wise, the RX10 III supports SD cards and Sony’s proprietary Memory Stick formats, providing more options and faster write speeds compared to NX3000’s microSD slot.

Price and Value: What Are You Getting for Your Bucks?

The NX3000, priced around $900, is an affordable stepping stone into APS-C mirrorless photography. It gets much right for casual shooters or cheapskates seeking solid image quality in a lightweight design, but with limited pro features.

The RX10 III costs about $1400, reflecting its versatile superzoom lens, advanced video capabilities, weather-sealing, and superior controls. While pricier, it delivers a one-body solution for many scenarios, reducing the cost and hassle of multiple lenses.
