Physical Design & Handling: Comfort Meets Portability

Before you even press the shutter, the feel of the camera in your hands sets the tone of your shooting experience. Both the Olympus E-PM1 and Samsung NX mini sport rangefinder-style designs aimed at portability. However, their approach to size, weight, and control layout reveals distinct philosophies.

Olympus leaned into a sturdier build with a slightly larger footprint and weight that lend confidence during handling. The E-PM1 measures 110 x 64 x 34 mm, weighing about 265 grams, comfortably fitting in one hand with room for grip stability. The classic Micro Four Thirds lens mount means access to a broad lens ecosystem without excess bulk.

Conversely, the Samsung NX mini is noticeably lighter and thinner at 196 grams and 110 x 62 x 23 mm. It embraces pocketability above all, appealing to travelers and street shooters keen on discretion and minimalism.

This size difference is vividly illustrated below:

The E-PM1’s control scheme offers a more tactile experience. Buttons and dials provide immediate access to modes and exposure settings, suiting users who prefer direct interaction over navigating menus. The NX mini rounds this out with a more touchscreen-oriented interface, minimizing physical controls but including a tilt-able screen for versatile shooting angles. From a usability standpoint, the E-PM1 feels more traditional and professional, while the NX mini caters to simplicity and casual usage.

Comparing the tops reveals this contrast in control philosophy:

Key takeaway: If you prioritize ergonomic handling and physical controls during fast-paced shooting, the Olympus E-PM1 has the edge. For ultra-portability and a touchscreen-first interface, the Samsung NX mini wins.

Sensor and Image Quality: Size Does Matter

At the heart of any camera is the sensor - a decisive factor that affects image quality, depth of field control, and low-light performance. The Olympus E-PM1 sports a 12.3-megapixel Four Thirds sensor measuring 17.3 x 13 mm, whereas the Samsung NX mini features a 20.5-megapixel 1-inch BSI-CMOS sensor sized 13.2 x 8.8 mm.

Four Thirds sensors are physically larger than 1-inch types, allowing the E-PM1 to gather more light per pixel, which generally translates to lower noise and better dynamic range, especially in challenging lighting. The Olympus sensor also benefits from a proven, well-optimized pipeline with the TruePic VI processor, delivering reliable color fidelity and sharp results suitable for high-quality printing up to A3 size.

Meanwhile, the Samsung’s smaller 1-inch sensor benefits from back-side illumination (BSI) technology and higher megapixel count, theoretically enabling more detailed images in ideal lighting. However, higher resolution on a smaller sensor can lead to greater noise levels at high ISO settings.

Let’s visually contextualize the sensor dimensions:

DxOMark scores corroborate this: Olympus E-PM1’s overall score stands at 52 with notable 21 bits color depth and 10.3 EV dynamic range, while the NX mini lacks official DxOMark data but, based on my own tests, shows slightly higher noise at ISO 1600 and above.

How does this translate to real photos? I shot a variety of scenes across lighting conditions; landscape and daylight portraits favored the E-PM1’s color nuances and gradation, while the NX mini excelled in sharpness in bright, controlled environments.

Sample images from both cameras show tell-tale distinctiveness:

Verdict: For overall image quality, especially when shooting portraits or landscapes where tonal gradation and noise matter, Olympus’s larger sensor is advantageous. Samsung offers more megapixels, but the smaller sensor’s noise profile and dynamic range slightly limit versatility.

Viewing and Interface: Screen Technology Shapes Workflow

Both cameras abandon the traditional optical viewfinder for a live view LCD, reflecting their entry-level, mirrorless design. However, their approach to viewing and interface diverges meaningfully.

The Olympus E-PM1 features a fixed 3-inch HyperCrystal LCD with an anti-reflective coating and 460k-dot resolution. This screen delivers clear images with good daylight visibility, though the inability to tilt or swivel restricts shooting angles, which can make low or overhead compositions less convenient.

In contrast, the Samsung NX mini boasts a 3-inch 461k-dot TFT LCD with 180-degree tilt enabling flexible framing for selfies or creative angles. Its touchscreen functionality enhances ease of use, allowing tap-to-focus and menu navigation - big pluses for casual shooters or vloggers who need quick control.

A visual comparison accentuates usability differences:

Neither camera includes a built-in electronic viewfinder, a potential drawback for bright outdoor shooting or photographers accustomed to composing via eye-level finders. Practically, this means the LCD is your sole window, necessitating consideration of viewing conditions.

Bottom line: If you desire a tilting touchscreen for creative framing and simplified operation, go with Samsung NX mini. If you prefer a glare-resistant, fixed screen with more traditional buttons, Olympus E-PM1 fits the bill.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus (AF) capabilities can make or break your shooting experience, especially when capturing fleeting moments in wildlife or sports photography.

The Olympus E-PM1 employs a contrast-detection autofocus system with 35 selectable points, including face detection and multi-area focusing. While its AF is decent for an entry model, it lags behind modern mirrorless standards in speed and tracking persistence. In my field tests, hunting for focus on moving subjects in low light sometimes resulted in hunting or missed focus, though stationary subjects were easily locked.

Samsung’s NX mini offers 21 contrast-detection autofocus points and adds touch-AF with face detection. Interestingly, it lacks continuous AF tracking, making it less reliable for erratic subjects or sports but nice for static or posed shots. Its touchscreen AF improves manual focus precision, an advantage for macro or creative focus pulls.

From judgment across photographic genres:

• Portraits: Both effectively detect and focus on faces, with Olympus slightly more reliable in continuous AF.
• Wildlife & Sports: Olympus edges ahead thanks to continuous AF and a faster shutter ceiling (1/4000s vs 1/16000s max shutter speeds - but shutter speed may be less relevant here since Samsung’s shutter max is higher, yet mechanical vs electronic speeds differ).
• Macro: Touch AF on Samsung allows fine control, compensating for less autofocus sophistication.

Takeaway: Olympus E-PM1’s AF system provides slightly better continuous tracking, making it more versatile across fast-action scenes, whereas Samsung NX mini's touch control excels in deliberate, static shooting.
