Sizing Up the Sensors: Image Quality Foundations

At the heart of image quality lies sensor size and technology - key factors dictating noise performance, dynamic range, and depth of field capabilities.

The Olympus E-M1 features a 17.3 x 13 mm Four Thirds CMOS sensor with 16 megapixels resolution. Combined with the TruePic VII image processor, this sensor delivers commendable noise control and color depth, balancing resolution and low-light sensitivity to suit a broad range of applications. Its sensor area of approximately 224.9 mm² provides a moderate surface for capturing light, translating to respectable dynamic range - measured at 12.7 EV by DXOmark - and a color depth of 23 bits, enabling smooth tonal gradations especially appreciated in portrait and landscape shoots.

The Samsung NX mini, with its 13.2 x 8.8 mm 1"-type BSI CMOS sensor, pushes resolution boundaries to 20.5 megapixels but with a notably smaller sensor area of 116.2 mm². While the backside-illuminated (BSI) design aids in gathering light more efficiently, inherent constraints of sensor size mean elevated noise at higher ISOs and restricted dynamic range - though precise DXOmark data is unavailable, real-world use reflects a narrower exposure latitude compared to larger sensors. The NX mini’s maximum native ISO tops out at 12,800 (expandable to 25,600), yet noise becomes intrusive beyond ISO 1600 in practical shooting.

In essence, the Olympus sensor’s larger size and balanced resolution favor critical image quality and low-light versatility, while the NX mini’s sensor caters to those trading off ultimate quality for compactness and resolution.

Tailoring Composition: Displays and Viewfinding Solutions

Control over framing and review is tightly linked to viewfinder and LCD screen design.

The E-M1 is equipped with a bright electronic viewfinder (EVF) boasting 2.36 million-dot resolution and 0.74x magnification, delivering an immersive, 100% coverage experience. This EVF excels in bright outdoor conditions, facilitating precise composition and focus verification. Coupled with a 3" tilting touchscreen LCD (1,037k dots), it supports flexible shooting angles and intuitive menu navigation.

Samsung’s NX mini, omitting an EVF entirely, instead features a 3" TFT LCD with a 461k-dot resolution and a 180-degree tilt capable of flipping upwards, optimized for selfies and vlogging. While the touchscreen interface is responsive, its lower resolution and lack of an eye-level finder limit precision in bright ambient light, posing challenges in direct sunlight or fast-paced shooting.

Therefore, for photographers who need reliable framing tools and manual focusing aids, the E-M1’s EVF stands as a decisive advantage, whereas the NX mini targets casual users comfortable relying on live view alone.

Autofocus Systems: Technical Depth and Real-World Speed

An autofocus (AF) system can make or break photographic success, especially in dynamic situations like wildlife or sports.

The Olympus E-M1 boasts a sophisticated hybrid autofocus system combining 81 phase-detection points - offering swift, predictive tracking - with 121 contrast-detection areas enhancing precision, especially in Live View mode. This hardware-driven approach achieves consistent autofocus acquisition in under 0.1 seconds during daylight, maintaining accurate subject tracking across the frame, including face and eye detection. The E-M1 supports continuous AF and manual focus override, crucial for professional flexibility.

By contrast, the Samsung NX mini implements a contrast-detection-only autofocus solution with 21 focus points, which by nature is slower and potentially less reliable, particularly in low contrast or rapidly changing scenes. It lacks phase-detection and AF tracking features, requiring more manual intervention in challenging conditions. While the autofocus is adequate for general photography and still subjects, it may lag behind E-M1’s performance when photographing moving subjects such as in sports or wildlife.

In summary, Olympus’s autofocus system sets a high standard suitable for demanding scenarios; Samsung’s system, meanwhile, aligns with its entry-level role focusing on simplicity.

The E-M1 can shoot up to 10 frames per second (fps) with autofocus tracking enabled, facilitated by its advanced mechanical shutter and responsive processor. Its shutter speed range from 1/60s to 1/8000s offers flexibility across lighting conditions and creative exposures. Moreover, sensor-based 5-axis image stabilization reduces motion blur during handheld bursts.

The NX mini supports continuous shooting at 6 fps, slower but still sufficient for casual capture. Its shutter speeds stretch from 30s (allowing long exposures) to 1/16000s (likely achieved via electronic shutter), affording creativity modalities unseen in many competitors - albeit with a trade-off in rolling shutter tendencies in electronic shutter mode.

While both cameras cover different performance niches, the Olympus unit’s faster burst rate and superior stabilization empower professional-grade action photography.

Exploring Lens Ecosystems and Image Stabilization

Lens selection deeply affects versatility, and image stabilization safeguards sharpness handheld.

The Olympus E-M1 uses the Micro Four Thirds lens mount, supported by an extensive catalog totaling over 100 lenses from Olympus, Panasonic, and third-party manufacturers. This ecosystem spans fast primes, rugged telephotos, wide angles, specialized macro optics, and cinema lenses, enabling customized setups for all genres.

Equipped with sensor-shift 5-axis stabilization, the E-M1 compensates for yaw, pitch, roll, and X/Y shifts, delivering up to 4-5 stops of stabilization regardless of attached lens, which not only aids stills but greatly enhances video steadiness.

In stark contrast, the NX mini employs the proprietary Samsung NX-M mount, regrettably limited to just two lenses, both prime optics designed to preserve compactness - the 9mm f/3.5 pancake and 17mm f/1.8. This limitation restricts creative scope, especially in telephoto or macro realms. Also, the NX mini lacks built-in image stabilization, relying solely on lenses with optical stabilization (which the NX mini’s lenses do not offer), imposing constraints on handheld slow shutter use and video smoothness.

For photographers valuing extensive glass options and stabilization for diverse shooting, Olympus’s advantage is clear and heavily weighted.

Battery Life and Practical Shooting Considerations

Reliable power management is often underestimated yet critical in fieldwork.

The Olympus E-M1 employs the BLN-1 battery pack, delivering approximately 350 shots per charge per CIPA testing standards. While moderate for a mirrorless system, the option to carry spare batteries is essential for professional assignments or day-long shooting. Its single SD card slot supports SD/SDHC/SDXC formats with wide compatibility, allowing users to flexibly manage storage.

The NX mini, conversely, excels with a remarkable 650 shots per charge using its B740 battery, befitting travel and casual shooters requiring longer sessions between battery swaps. Though it supports only a single microSD card slot (a more compact but usually slower storage format), this aligns with its portability ethos.

This presents a tradeoff: Olympus offers higher performance at the expense of battery endurance, whereas Samsung prioritizes longevity.
