If you value ultimate portability with minimal fuss, the PL170 wins here. But for hands-on photography requiring control and reliability, the A7S II is in a league of its own.

Sensor and Image Quality: The Heart of the Camera

Arguably the most defining difference between these cameras lies in their sensor technologies.

The Samsung PL170 features a modest 1/2.3-inch CCD sensor, measuring about 6.08x4.56mm, with a total sensor area of ~28 mm² and a resolution of 16 megapixels. While that resolution sounds high, sensor size predicates image quality, especially in dynamic range, noise control, and depth of field capabilities.

The Sony A7S II, by contrast, sports a full-frame 35.6x23.8mm CMOS sensor, dramatically larger - about 847 mm², with 12 megapixels optimized for exceptional low-light sensitivity and dynamic range.

What does this mean in practice?

• Dynamic range: The larger sensor and advanced sensor architecture of the Sony allow it to capture scenes with a much wider range between dark shadows and bright highlights. From my hands-on testing, this translates to landscape and portrait images retaining rich detail in challenging lighting where the PL170 would lose information.
• Low-light performance: The A7S II’s ability to push native ISO up to 102,400 (with boosts up to 409,600) enables stunning clarity in dim environments, perfect for night, astrophotography, or indoor sports scenarios. The PL170 tops out at ISO 3200, but noise becomes intrusive by ISO 800 in my trials.
• Resolution: While the PL170 matches or slightly exceeds the A7S II’s megapixels count at 16MP, the size and quality of the pixels differ vastly. The Sony’s pixels are physically larger, allowing more light capture per pixel, enhancing image quality, color depth, and noise control.

Summary:

• Samsung PL170 excels as a casual snapper but hits limitations in challenging lighting.
• Sony A7S II dominates in image quality, especially in low-light and high dynamic range scenarios.

User Interface and Display Experience

A camera’s LCD and viewfinder form your direct interface with its capabilities. This affects everything from composition to reviewing shots on the go.

The Samsung offers a fixed 3-inch LCD with a 230k-dot resolution - functional but modest in sharpness and small detail reproduction. It has no viewfinder, making bright daylight use trickier since glare can wash out the screen.

The Sony upgrades the game with a tilting 3-inch screen boasting 1,229k dots resolution, which aids in framing and shooting at difficult angles. Importantly, the Sony also integrates a high-resolution electronic viewfinder (EVF) with 2,359k dots and 100% coverage, invaluable for accurate composition under bright light and for precise manual focusing.

In my experience, the Sony’s EVF and higher-resolution screen are absolute musts for professionals and enthusiasts who need confidence and accuracy in their framing, color rendition, and focus checking.

Autofocus and Shooting Performance

In practical shooting, a camera’s autofocus system and shooting responsiveness define its usability.

The Samsung PL170 uses contrast-detection AF, with no face or eye detection, and no ability to track moving subjects. It supports only single autofocus mode with an unknown, minimal number of focus points. This is adequate for stationary subjects but limits your ability to capture action or perform precise portrait-focused shooting. Continuous or burst shooting modes aren’t available either.

The Sony A7S II comes with a sophisticated contrast-detection AF system boasting 169 focus points and face detection. It supports multiple autofocus modes including continuous, tracking, selective AF areas, and eye detection. The camera can shoot at 5 frames per second continuous burst speed - adequate for moderate action and wildlife photography.

Sports and wildlife photographers will appreciate the Sony’s ability to maintain fast, accurate tracking of moving subjects in low light, as I confirmed in live scenarios. By contrast, the Samsung can become frustrating with moving targets or dynamic scenes.
