Olympus E-M1 II vs Samsung NX300M: A Hands-On Comparison from a Seasoned Camera Tester

I’ve spent the past 15 years shooting professionally with countless cameras across genres - from intimate portrait sessions to rugged wildlife adventures. Today, I’ll take you on an in-depth, side-by-side exploration of two very different mirrorless cameras: the pro-grade Olympus OM-D E-M1 Mark II (E-M1 II) and the entry-level Samsung NX300M. Despite their different eras and market segments, this comparison reveals compelling insights for photographers considering these systems.

Using real-world test shoots, detailed technical analysis, and extensive hands-on time, I’ll dive into performance, image quality, ergonomics, and suitability for various photography disciplines. I also integrate seven carefully selected images that highlight key points visually, so you’ll understand not just numbers but actual use cases and experiences.

First Impressions and Handling: Size, Weight, and Ergonomics

Handling my cameras is always where the intimate connection begins. You want controls under your fingertips, a comfortable grip, and confidence that your gear won’t fatigue you on long shoots.

Here, the Olympus E-M1 II impresses immediately with its robust, SLR-style mirrorless body. It weighs a solid 574 grams, offering a reassuring heft without being unwieldy. The Samsung NX300M is lighter at 331 grams, targeted more toward casual users seeking portability.

Physically, the Olympus has classic ergonomics - prominent dials, deep grip, and weather sealing to protect against dust and moisture. The Samsung is more compact, slimmer, and carries a rangefinder-style body, which some street photographers will appreciate for discretion.

From my extensive experience shooting long hours in nature and urban environments, I find the Olympus’s deeper grip and heft make it easier to stabilize handheld, which is crucial for telephoto and macro work. The Samsung’s slimness works well for casual travel or street walking but sacrifices some control comfort.

Looking at the top, the Olympus has a more elaborate control layout - multiple dials and customizable buttons allowing quick exposure adjustments mid-shoot. The Samsung is minimalist with fewer controls, meaning more reliance on menus and touch input.

Bottom line: Olympus E-M1 II is built for demanding, professional workflows, while Samsung NX300M emphasizes portability and simplicity.

Sensor and Image Quality: Decoding the Heart of the Cameras

Sensor size and technology greatly influence image quality, especially under challenging conditions. The Olympus uses a Four Thirds 20MP sensor (17.4 x 13 mm), while the Samsung packs a larger APS-C 20MP sensor (23.5 x 15.7 mm). Let’s see what this means practically.

The larger APS-C sensor generally yields better high-ISO performance and dynamic range, which I confirmed in my low-light test sequences. Photos from the Samsung NX300M showed cleaner shadows and richer highlight retention at ISO 3200 compared to the Olympus’s more evident noise and clipping tendencies, attributable to the smaller sensor.

However, Olympus’s TruePic VIII processor and refined micro four thirds optics deliver excellent detail and color fidelity, particularly in well-lit environments. Its sensor area is roughly 226 mm² compared to Samsung’s 369 mm², meaning less light-gathering power but more compact lenses and a doubled crop factor (~2.0x vs ~1.5x for Samsung).

In resolution terms, both produce sharp 20MP images: Olympus tops out at 5184 × 3888, Samsung at 5472 × 3648. The slight difference in aspect ratio (4:3 Olympus, 3:2 Samsung) affects framing - portrait shooters may prefer Olympus for its vertical real estate.

In practical portrait sessions, I noticed the Olympus’s colors leaned toward natural skin tones with warm gradients. Samsung’s images sometimes felt cooler but captured intricate texture well. Olympus’s lack of an anti-aliasing filter contributes to crisp detail but can risk moiré on fine patterns.

LCD and Viewfinder: Composing Your Shots in Comfort

One aspect where user experience can make or break a shoot is the viewing system: how well does the camera show your subject in real-time?

The Olympus E-M1 II boasts a 3-inch fully articulating touchscreen with 1,037k dots, as well as a 100% coverage electronic viewfinder rated at 2,360k dots and 0.74x magnification. The Samsung NX300M lacks a built-in viewfinder entirely but offers a 3.3-inch tilting OLED touchscreen with 768k dots.

Personally, I esteem Olympus’s EVF highly when shooting outdoors - it helps in bright sunlight where LCD glare can be severe. Its articulating screen allows creative angles - perfect for macro work or over-the-head shots on rooftops. Samsung’s OLED screen is vibrant with excellent color reproduction but can be challenging in direct light due to a lack of a viewfinder.

For street photography, I found Olympus’s EVF invaluable for discreetly composing shots without raising your camera too high, while Samsung users need to rely more on the LCD, which may draw attention.

In terms of interface, both employ touchscreens effectively but Olympus includes customizable buttons and dials to optimize quick access - a boon when light or timing demands rapid changes.

Autofocus Systems and Speed: Capturing Fleeting Moments

Autofocus can make or lose critical shots, especially in wildlife or sports photography. The Olympus and Samsung adopt hybrid systems combining phase-detection and contrast-detection AF.

• Olympus E-M1 II: 121 focus points with reliable face detection, also supports continuous, single, and selective AF modes.
• Samsung NX300M: 247 focus points but relies solely on contrast detection with fewer advanced tracking features.

In my extensive wildlife field tests, Olympus’s AF system was remarkably agile, locking quickly even on erratically moving birds in flight. Burst shooting at an astounding 60 fps (electronic shutter) or up to 15 fps (mechanical shutter) complemented the autofocus perfectly. Samsung allows burst shooting at up to 9 fps but with slower autofocus responsiveness and noticeable hunting in low contrast scenes.

Both have eye detection for portraits, but Olympus’s I found more precise and consistent. Samsung’s focus struggled occasionally with shallow depth-of-field portraits, particularly in dimmer light.

Continuous autofocus tracking during sports events was noticeably better on Olympus - I captured sharp frames of soccer action sequences that Samsung simply failed to nail.

Overall, Olympus shines in autofocus sophistication, essential for advanced and professional shooters. Samsung is more entry-level in this sphere, suitable for casual or beginner users.

Build Quality and Durability: Can These Cameras Take a Beating?

Shooting outdoors demands cameras that can endure weather and environmental stress. The Olympus E-M1 II scores heavy points with weather sealing protecting against dust and splashes - a feature I stress-tested extensively in rainy forest treks. I was able to shoot without a rain cover, an assurance Samsung can’t provide.

The Samsung NX300M is unsealed - its plastic body construction makes it lighter but vulnerable to humidity and dust ingress, better suited for indoor or clear-weather situations.

I also noted Olympus’s tougher shutter mechanism rated at 200K cycles, vs. Samsung’s more modest durability expectation. This contributes to Olympus’s positioning as a pro workhorse.

Lens Ecosystem: The Backbone of Your System

No camera shines alone. The lens mount and available optics determine how flexibly you can shoot.

Olympus uses the Micro Four Thirds mount, with access to 107 native lenses from Olympus, Panasonic, and third parties. This extensive ecosystem includes fast primes, versatile zooms, excellent macros, specialty lenses like fisheyes, and impressive weather-sealed options.

Samsung’s NX mount has a modest selection - about 32 lenses. While covering essential focal lengths, it lacks the breadth and depth of enthusiast or professional-grade glass. This limits versatility, particularly for wildlife telephoto reach, macro, or cinema lenses.

For macro photography, Olympus’s range includes several stabilized, close-focusing lenses designed to exploit its sensor-based 5-axis image stabilization system. In contrast, Samsung’s lack of in-body stabilization means macro shots require extremely steady handholding or tripods.

Image Stabilization: The Silent Hero for Handheld Excellence

Olympus’s hallmark is its sensor-based 5-axis image stabilization. This tech compensates for pitch, yaw, X/Y shift, and roll, delivering up to 5 stops of shake correction. In practical shooting, that translates to sharp handheld telephoto and macro photos where shutter speeds would otherwise be too slow.

Samsung NX300M lacks in-body stabilization entirely; stabilization depends solely on lens-based IS if available, which is limited in the NX lineup.

During my low-light portrait and nighttime handheld tests, Olympus consistently produced cleaner, sharper images without needing a tripod. Samsung required pushing ISO higher or using flashes, resulting in more noise or flash shadows.

Video Capabilities: Shooting Moving Pictures

Both mirrorless cameras offer video specs suited for casual shooters but diverge significantly in quality and professional use.

Olympus E-M1 II supports 4K DCI video (4096×2160) at 24 fps and UHD 4K (3840×2160) at 30 fps, recorded in MOV H.264 with linear PCM audio. It also includes microphone and headphone jacks for external audio control, 3.5 mm ports essential for professional video workflows.

Samsung NX300M maxes out at Full HD 1920×1080 at 30 fps, with no advanced codecs or external audio inputs. While fine for family or casual content, it won’t satisfy videographers craving UHD quality or advanced sound control.

Olympus also offers timelapse recording and manual control over exposure in video mode, enhancing creative options. The NX300M has fewer manual video features and no timelapse.

Battery Life and Storage: Keeping You Shooting Longer

Practicality also means not worrying about power during day-long sessions.

• Olympus E-M1 II: Battery rated for 350 shots per charge using the BLH-1 pack, supports dual SD card slots for overflow or backup. I found this plenty for most shoots, especially with storage flexibility, mitigating SD card failure risk.

• Samsung NX300M: Rated 330 shots per charge, uses a proprietary BP1130 battery with a single SD slot. Fewer storage options and shorter battery life can frustrate long-duration shooting.

XLR adapters are unsupported on either, but Olympus’s USB 3.0 and HDMI out enable tethered shooting and faster file transfers - a boon in professional studios.
