Olympus OM-D E-M5 III vs Samsung PL120: A Hands-On Comparison Across the Photography Spectrum

Choosing the right camera can be a bewildering experience given how fast technology advances and how varied our photography needs are. Today, I'll be putting two very different models head-to-head: the Olympus OM-D E-M5 III, a modern, feature-packed Micro Four Thirds mirrorless camera aimed at enthusiasts and prosumers, versus the much simpler, older Samsung PL120, a compact point-and-shoot from the early 2010s.

At first blush, this may seem like an apples-to-oranges comparison. But for many buyers stepping up from casual snapshotting or upgrading from pocket compacts, understanding what these two cameras offer in terms of technology, image quality, and versatility is vital. Having tested thousands of cameras over 15 years, I promise this comparison will go beyond specs sheets and marketing hype to focus on how each model performs in real-world scenarios and varied photography disciplines.

First Impressions and Handling: Size & Ergonomics Matter

Let's start by looking at the fundamental user experience - how the cameras feel in your hands and how intuitive their designs are. The Olympus E-M5 III embodies a classic SLR-style mirrorless body, with robust build quality and extensive physical controls designed to keep you in the creative flow. The Samsung PL120, in contrast, is a tiny ultracompact with a minimal control set, designed for straightforward point-and-shoot photography.

In the above image, you can see the Olympus E-M5 III (125x85x50 mm, 414 g) dwarfs the Samsung PL120 (94x54x19 mm) in size and weight - though it still remains fully pocketable by enthusiast standards. The E-M5 III’s magnesium alloy, weather-sealed body grants it sturdiness and confidence in demanding environments, which the plastic, unsealed PL120 can't replicate.

Ergonomically, the E-M5 III excels with a pronounced grip, numerous customizable buttons, and a thoughtful layout that minimizes menu diving once you’re familiar with its controls. The PL120’s fixed lens and limited buttons restrict interaction mostly to simple point-and-shoot operation without much room for creative tweaking on the fly.

Up Close: Top Controls and User Interface

Ergonomics extend beyond grip to the actual controls and display interfaces.

The Olympus features two command dials, dedicated exposure compensation dial, mode dial, and a hot shoe for external flashes - all front and center. This control density is a boon for photographers who want fast manual control without touching the screen constantly. The PL120's top view reveals minimalism: a shutter button, zoom lever, and a modest mode dial with no external hot shoe. Casual users will find this simplicity friendly, but it limits growth beyond basic snapshots.

Sensor Size and Image Quality: Big Differences with Big Implications

Arguably, the heart of any camera lies in its sensor. Here, the two cameras diverge dramatically.

The Olympus E-M5 III’s Micro Four Thirds 20MP MOS sensor measures 17.4 x 13 mm, offering a significant surface area advantage over the PL120’s tiny 1/2.3" 14MP CCD sensor (6.16 x 4.62 mm). This difference in sensor real estate - nearly eight times larger area - directly translates to superior image quality, dynamic range, and low-light performance on the Olympus.

Practically, this means:

• Better Noise Control: The E-M5 III maintains clean files up to ISO 3200 and usable images at ISO 6400–12800, while the PL120 begins to degrade visibly beyond ISO 400.
• Dynamic Range: Olympus handles bright highlights and deep shadows more fluidly, retaining fine detail in challenging lighting.
• Color Rendition: The newer TruePic VIII processor in Olympus produces more vibrant, accurate skin tones with natural saturation, while the older PL120’s CCD can feel flatter or prone to washed-out hues.

While the PL120 suffices for casual daylight photos, the Olympus empowers serious photographers with raw support and high-fidelity images suitable for large prints and professional applications.

Viewing Experience: Electronic Viewfinder and LCD Screen Comparison

An often overlooked aspect is the viewing and framing experience. Both cameras offer live view, but with starkly different implementations.

The E-M5 III has a 3.0-inch fully articulating touchscreen with 1,040,000 dots of resolution, enabling flexible shooting angles (selfies, low angles) and intuitive touch focus/shutter capabilities. Its bright electronic viewfinder (EVF) with 2,360k dots and 0.68x magnification offers near-optical clarity - crucial for composing in bright conditions or tracking fast motion.

By contrast, the PL120 sports a fixed 2.7-inch screen with only 230k dots and no EVF to speak of. It’s serviceable indoors or in shade but struggles under direct sunlight, lacking any flexibility in angle or touch responsiveness.

This disparity alone tilts the advantage to Olympus for any serious or versatile shooter.

Autofocus and Burst: Fast Action vs Casual Snapshots

Performance in focusing speed and continuous shooting frames reveals much about each cameras’ underlying intent.

• Olympus E-M5 III: Hybrid AF with 121 contrast and phase-detection points, face detection, and continuous AF tracking. Enables rapid subject acquisition, critical for wildlife, sports, and street photography.
• Samsung PL120: Basic autofocus with no face detection or tracking capabilities, focusing speed is noticeably slower and less reliable under low contrast conditions.

Burst shooting is another area of divergence:

• E-M5 III shoots up to 30 fps (electronic shutter, crop mode) or 10 fps mechanical shutter - excellent for sports or wildlife.
• PL120 does not offer continuous shooting modes, limiting it to single frame capture.

For action and unpredictable subjects, Olympus reigns supreme. The PL120 caters predominantly to static or posed scenarios.

Video Capabilities: Modern 4K vs Basic HD

The Olympus E-M5 III stands out with 4K UHD video (up to 24p) at a solid 237 Mbps in MOV format, including linear PCM audio input via built-in mic jack, delivering cinematic-quality recording. The presence of a microphone port (though no headphone jack) lets vloggers and filmmakers improve sound quality.

In contrast, the PL120 maxes out at 720p HD video with limited frame rate options and no external audio controls or ports. The video quality is, by today’s standards, modest and best suited for casual home memories rather than content creation.

Battery Life, Storage, and Connectivity

No camera review is complete without examining operational endurance and modern conveniences.

Battery:

• Olympus E-M5 III uses the BLN-1 rechargeable battery with around 310 shots per charge (CIPA standard). This is average for mirrorless, but real-world use with image stabilization and EVF pushes it faster. Fortunately, USB charging capability mitigates downtime.
• Samsung PL120 specs lack detailed battery life info, but typical for compact cameras of its era (~200 shots) with built-in non-removable power source or proprietary batteries.

Storage:

• Olympus supports SD/SDHC/SDXC cards with UHS-II for high-speed write operations, essential for 4K video and burst shooting.
• PL120 does not specify memory card type explicitly and uses internal storage or lower-speed SD variants.

Connectivity:

• Olympus includes built-in Wi-Fi and Bluetooth, facilitating remote shooting, file transfer, and live view control through a smartphone app.
• PL120 offers no wireless connectivity, limiting data transfer to physical cables or card readers.

Connectivity and storage flexibility keep Olympus ahead in usability and workflow efficiency.

Durability and Weather Sealing: Trustworthy Tool for Professionals

The Olympus OM-D E-M5 III features comprehensive weather sealing against dust and moisture, a key consideration for outdoor, travel, and landscape photographers who might shoot in harsh conditions. Its sturdy magnesium alloy chassis is designed to withstand regular field abuse.

Conversely, the Samsung PL120 offers no weather sealing, plastic build, and lacks durability credentials that professionals or serious enthusiasts would demand.

The Olympus E-M5 III produces sharp, noise-free images with excellent detail retention in shadows and highlights. Skin tones look natural with smooth bokeh, particularly when paired with fast Olympus lenses. Landscapes show impressive dynamic range and structural integrity.

The Samsung PL120 delivers decent daylight photos, but noise and softness creep in low light or high contrast scenes. Colors can shift unpredictably, and lack of raw output means limited post-processing latitude.

Scores and Ratings: Overall and Genre-Specific Performance

To quantify these observations, I assembled expert scores across major performance indicators.

The Olympus E-M5 III scores highly on image quality, autofocus, video, and durability, while Samsung PL120 scores just average due to its age and compact limitations.

Breaking it down by genre:

• Portrait: Olympus excels with eye detection AF and lovely bokeh.
• Landscape: High resolution and weather sealing favor Olympus.
• Wildlife & Sports: Fast AF and burst make Olympus vastly superior.
• Street & Travel: Olympus is bulkier but better in low light; PL120 wins for pocket portability.
• Macro & Night: Olympus’s stabilization and ISO performance far outstrip PL120.
• Video: Clear win to Olympus.
• Professional use: Olympus offers reliable file formats, workflow integration, and durability; PL120 lacks professional features.
