First Impressions: Size, Build, and Handling

Physically, these cameras reveal their era and design philosophies at a glance. The Samsung NX30 boasts a compact, mirrorless setup with SLR-style ergonomics, designed for travel and versatility. In stark contrast, the Sigma SD10's mid-size DSLR body feels more substantial and traditional, reflecting 2004 engineering priorities.

At 375 grams and dimensions of 127x96x58mm, the NX30 is notably lighter and smaller than the hefty SD10, weighing 950 grams and measuring 152x120x79mm. In my hands, the NX30’s grip feels nimble yet secure, making it easy to carry around all day without fatigue - a critical factor for event or travel photographers. The SD10’s weight, while offering a solid, reassuring heft, can be cumbersome on longer shoots, though it provides stability when paired with large lenses.

Ergonomically, the NX30’s body benefits from a fully articulated 3-inch AMOLED touchscreen, which feels responsive and bright even in sunlight. The Sigma’s 1.8-inch fixed LCD pales in comparison - both in size and resolution - making image review and menu navigation less intuitive.

Comparing the top controls gives even more insight:

The NX30 features thoughtfully placed dials and buttons that are fully customizable, suited for quick in-the-moment adjustments. The SD10 keeps to a minimal, dated layout lacking the modern convenience of illuminated buttons or touch functionality. For photographers who prioritize palpable tactile control and a modern user interface, the NX30 emerges ahead clearly here.

Sensor Technology and Image Quality: A Tale of Two Designs

Image quality differences are often the heart of any camera comparison, and here the story is rich with technology contrasts.

Sensor Specifications - Size, Resolution, and Type

• The Samsung NX30 sports a 20MP APS-C CMOS sensor (23.5x15.7mm), paired with a DRIMe IV image processor.
• The Sigma SD10 holds a 3MP APS-C Foveon X3 sensor (20.7x13.8mm). Despite the low megapixel count on paper, its layered Foveon sensor captures RGB color data at each pixel depth, offering unique color fidelity.

In practical use, the NX30’s sensor resolution - 5,472 x 3,648 pixels - translates into sharp, high-detail images ideal for larger prints and cropping. The SD10’s output is considerably lower (2,268 x 1,512), limiting enlargements but rewarding with extraordinary color depth and tonality.

Dynamic Range and ISO Performance

Though Sigma’s Foveon sensor is lauded for color rendition, its dynamic range and high ISO capability trail significantly behind the NX30. Samsung’s sensor achieves a DXO-marked 12.4 EV dynamic range and performs well up to ISO 25600 (native max), delivering cleaner images in shadows and highlights. The SD10 maxes out at ISO 800 (boostable to 1600), with noise becoming intrusive beyond ISO 400.

For landscape photographers who demand wide dynamic range to capture rich skies and deep shadow detail, the NX30 is clearly superior. However, for controlled studio portraits where lighting is carefully managed, the SD10’s color depth can deliver lovely skin tone gradients.

Autofocus Systems and Speed: Hybrid vs Contrast Detection

Autofocus (AF) performance is a decisive factor depending on shooting style, especially for action, wildlife, or street work.

The Samsung NX30 employs a hybrid AF system with 247 focus points combining phase detection and contrast detection. It supports touch-to-focus on the AMOLED screen and features face detection. In live tests, the NX30 locks focus swiftly and tracks moving subjects with reliability, handling sudden changes in distance quite well.

The Sigma SD10, however, offers only contrast-detection AF with no phase-detection points and a significantly fewer number of focus points. AF speed is slower and less forgiving in low light or on moving subjects. There’s no face or eye detection assist.

This makes the NX30 markedly more versatile for sports, wildlife, and fast-paced event photography. The SD10’s AF can work well for deliberate, static shooting but may frustrate photographers needing responsive focus.

Displays, Viewfinders, and Interface Usability

The NX30 integrates a high-resolution electronic viewfinder (EVF) offering 100% coverage and 0.66x magnification, giving an accurate preview of exposure and color. The fully articulating AMOLED touch display enhances framing creativity and usability in unusual angles.

Conversely, the Sigma SD10 uses a traditional optical pentaprism viewfinder with 98% coverage and 0.77x magnification. While it provides a clear, natural viewing experience, the lack of an EVF means no exposure preview or real-time digital effects.

The Sigma’s small fixed screen limits image checking, and navigating its menus feels archaic compared to the NX30’s intuitive, touchscreen-based controls.

For photographers who embrace live digital previews and flexible shooting positions, the NX30's interface is clearly easier on the eyes and workflow.

Lens Ecosystem and Compatibility

Lens options heavily influence a camera’s creative flexibility.

The Samsung NX mount offers 32 native lenses, including primes and zooms covering wide to telephoto ranges, allowing adaptability for portraits, wildlife, macro, and landscapes. The mount supports modern autofocus motors, image stabilization in lenses, and well-optimized optics.

Sigma’s SA mount, while boasting a respectable 76 lenses, is older and less common outside Sigma’s own lineup. Many lenses lack autofocus motors or image stabilization, requiring manual focus or adaptation.

If you want access to a contemporary and growing lens ecosystem with advanced AF and optical features, the NX30 system holds an edge.

Battery Life and Storage Options

Battery longevity can dictate shooting endurance on location.

Samsung’s BP1410 battery offers approximately 360 shots per charge, typical for mirrorless cameras. While not record-breaking, this is manageable for day shoots with occasional USB charging breaks.

The Sigma SD10’s battery data is sparse, but its older design generally demands more frequent replacements, and it uses Compact Flash Type I or II cards - in contrast to NX30’s SD/SDHC/SDXC cards, which are now industry-standard and faster.

From a practical standpoint, the NX30’s storage format offers faster write speeds and broader compatibility, improving workflow.

Connectivity and Video Capabilities

Modern photography increasingly integrates video and wireless sharing.

The Samsung NX30 supports Full HD 1080p video recording at 60fps, with external microphone input for audio monitoring. While it lacks 4K video or headphone jacks, its video quality and manual controls meet casual videographers' needs.

The Sigma SD10 is strictly photo-only, with no video recording capabilities. It also lacks wireless features; data transfer is through USB 1.0, making tethering and fast file transfer impractical.

For multimedia content creators or social shooters, this makes the NX30 the clear choice.
