The SD10’s pentaprism optical viewfinder provides 98% coverage with 0.77x magnification - ideal for precise composition in bright conditions. The NX300M omits an EVF altogether, instead leaning on its bright OLED touchscreen for framing, which is helpful but less effective in direct sunlight.

Tech Under the Hood: Sensor, Image Processing, and ISO Performance

At the heart of photographic quality lies the sensor. These two cameras couldn’t be more different here:

Sensor specifications: Samsung’s 20MP CMOS vs. Sigma’s unique 3MP Foveon X3 CMOS

• Samsung NX300M’s CMOS sensor: Measures 23.5x15.7 mm (APS-C) with a resolution of 20 megapixels (5472 x 3648). It utilizes standard Bayer filter technology paired with Samsung’s DRIMe IV processor - a combination delivering sharp images, decent noise handling, and good dynamic range for its class. Native ISO ranges from 100–25600 offer usable flexibility in low light.

• Sigma SD10’s Foveon X3 sensor: Slightly smaller at 20.7x13.8 mm with an effective 3 megapixels (2268 x 1512). However, its Foveon design captures all color layers at each pixel location rather than interpolating with a Bayer filter - a rare trait promising superior color fidelity and detail rendition. Yet, its ISO ceiling is much lower (max 800 native ISO, extendable to 1600), limiting low-light usability.

In hands-on tests, the NX300M delivers smooth, well-detailed images even above ISO 1600, making it versatile for diverse lighting situations - from indoor candids to street night shots. The SD10’s images exhibit exceptional color depth and micro-contrast when shot at base ISO, but noise rises quickly beyond ISO 400, and files can appear softer at higher ISOs.

Autofocus and Shooting Speed: Tracking the Moment

The NX300M features a hybrid autofocus system integrating contrast and phase detection with 247 focus points - impressive for an entry-level mirrorless. The camera supports face detection and tracking in live view, crucial for portraits and event photography.

Sigma’s SD10 employs a contrast-detection AF system with fewer focus points and lacks face or eye detection. Its autofocus speed is noticeably slower under challenging light or moving subjects.

• Continuous shooting: NX300M impresses with a 9 frames per second burst mode, beneficial for sports and wildlife action sequences.

• SD10, in contrast, does not specify continuous shooting speed but tests show it hovers around 2 fps - adequate for static subjects but limiting for fast action.

In wildlife and sports scenarios I tested, the NX300M’s autofocus reliably locked onto moving targets with fewer missed shots, while the SD10 struggled to maintain focus during rapid movement or low light, requiring more patience and user skill.

Viewfinder and Display Experience: Framing Your Shots

Display comparison: Tilting OLED touchscreen vs. fixed LCD screen

The Samsung NX300M’s backlit OLED touchscreen tilts for flexible angles, supports intuitive tap-to-focus, and provides rich color rendition - a joy when composing outdoors or reviewing images on the spot. Its higher 768k-dot resolution enhances detail clarity, especially useful in focus peaking and manual focus.

The Sigma SD10’s fixed 1.8" LCD is small and low-resolution by modern standards (130k dots), making menus and image playback less comfortable. Without live view, composing relies exclusively on the optical viewfinder.

For photographers accustomed to tactile button shooting and optical viewing, the SD10’s system is familiar but dated. NX300M’s live-view centric approach suits those comfortable with touchscreen interaction and mirrorless workflows.

Lens Ecosystem and System Compatibility: Growing With Your Gear

A camera is only as versatile as its lenses:

• Samsung NX mount system: While the NX300M is entry-level, it accesses a decent lineup of 32 native lenses (primes, zooms, macros) including affordable and third-party options, with a 1.5x crop factor.

• Sigma SA mount: The SD10 supports 76 lenses built for Sigma’s DSLR series, many catering to professional and specialty needs. Its 1.7x crop factor means lenses cover a narrower field of view than full frame.

Access to native lenses impacts long-term investment, especially if you anticipate genre shifts. The Samsung system today is largely discontinued with limited new glass, though reliable adapters can expand options. Sigma’s SA mount is niche with fewer modern lenses, and no native mirrorless support, which may discourage future upgrades.

Battery Life and Storage: Ready When You Are

The NX300M uses a compact BP1130 battery rated for approximately 330 shots per charge - a respectable number for a mirrorless offering in 2013. It accepts microSD/SDHC/SDXC cards in a single slot configuration.

The SD10 consumes more power due to its DSLR design and larger electronics, but official battery life figures are unavailable. It accepts CompactFlash Type I/II cards, still standard in professional circles at release.

For extended travel or event shoots, the NX300M’s lighter build and decent battery life aid mobility, while the SD10’s format may require extra batteries and bulkier storage.
