In contrast, the Sony A7S II is a substantial mirrorless camera with an SLR-style body built for professional handling.

Size wise, the ST95 measures a mere 92x53x17 mm, easily slipping into a pocket. Its ultracompact body means simplified controls and a fixed lens, targeting casual shooters or those who prize portability.

The Sony A7S II, measuring 127x96x60 mm and weighing significantly more, commands more space and presence. Designed with photographers who want full manual control and robust build, it offers extensive direct access dials, buttons, and deep grips for stability during long sessions.

Ergonomically, the Sony features a top-plate packed with control dials for shutter speed, exposure compensation, and various customizable buttons. The ST95 sports a minimalist control set with very limited manual override, reflecting its ease-of-use-first philosophy.

In practice: I found the ST95 easy for quick, everyday snapshots but frustrating if you want to experiment or exert creative control. The Sony A7S II excels for prolonged shoots where you want fast access to settings with excellent grip - essential for dynamic or challenging environments.

Summary: The ST95 suits ultra casual use and travel on a budget, while the A7S II demands a serious commitment and rewards with professional-level handling.

Sensor Technology and Image Quality

Understanding sensor technology is key to grasping the fundamental gap between these two cameras.

• Samsung ST95: Uses a small 1/2.3-inch CCD sensor (6.16 x 4.62 mm), 16 megapixels. Such sensors were common in compact cameras in its era but have distinct limitations: reduced dynamic range, noisy high ISO performance, and relatively limited color depth.
• Sony A7S II: Features a large full-frame (35.6 x 23.8 mm) CMOS sensor with 12 megapixels optimized for exceptional light sensitivity, dynamic range, and color fidelity.

What These Mean in Practice

• Resolution & Detail: Despite the ST95’s higher 16MP count, the tiny sensor offers less true detail and more noise than the Sony’s 12MP full-frame sensor due to physics - bigger sensor pixels gather more light, enhancing image quality.
• Dynamic Range: The A7S II’s sensor boasts roughly 13.3 stops of dynamic range, helping retain details in highlights and shadows critical for landscape and professional work. The ST95’s lack of tested dynamic range suggests limited latitude for recovery.
• Color Depth: Sony’s 23.6 bits of color depth facilitate richer, more nuanced colors suitable for professional editing workflows versus the ST95’s untested metric but known limitations.

If you’re shooting scenes with varied lighting, the Sony’s sensor vastly outperforms the Samsung’s. The difference is evident in shadows, highlights, and color accuracy.

LCD Screen and Interface Usability

A camera’s interface shapes your daily shooting experience.

• Samsung ST95: Fixed 3-inch LCD with low resolution (460 pixels). No touchscreen or articulating mechanism, limiting viewing angles and menu navigation speed.
• Sony A7S II: Higher-res 3-inch tilting LCD (1229 pixels) without touchscreen, but excellent for composing at odd angles and accessing menu items fast.

The A7S II’s reinforced interface complements its pro controls, allowing refined manual input and customization. The ST95 remains basic but functional for point-and-shoot style spontaneity.

Autofocus and Shooting Speed: Catching Fast Moments

AF systems and burst shooting capabilities vary drastically.

• Samsung ST95: No dedicated autofocus points, no face detection, no tracking, and no continuous AF modes. It uses contrast detection in a very rudimentary way. No continuous shooting specs were provided, signaling slow shooting speed.
• Sony A7S II: 169 focus points, face detection, tracking autofocus, AF-C for continuous focusing, and 5 fps burst shooting.

In my tests, the A7S II confidently tracked moving subjects during wildlife and sports shoots, locking focus quickly in dim conditions. The ST95 was laggy and prone to hunting or missed focus, unsuitable for anything beyond static subjects.

Lens Systems and Versatility

One of the biggest divides is lens availability.

• Samsung ST95: Fixed lens with a small zoom range (unspecified), designed for general snapshots only.
• Sony A7S II: Uses the versatile Sony E-mount, compatible with 121 lenses ranging from ultrawide to super-telephoto primes and zooms.

The Sony’s extensive lens library supports everything from ultra-high-res landscapes to macro, wildlife telephoto, and professional portrait lenses with beautifully wide apertures. The ST95 is locked into a tiny fixed zoom with limited creativity and optical quality.

Battery Life and Storage Options

• Samsung ST95: No published battery life, typical for compacts is short usage times (a few hundred shots per charge). Single storage slot, unspecified format.
• Sony A7S II: Rated at approx. 370 shots per battery (NP-FW50), supports SD and Sony Memory Stick cards.

The pro-oriented Sony supports longer shooting cycles but will demand spare batteries for heavy use. The ST95 battery will similarly need charging often but is more casual in use.

Build Quality and Weather Resistance

No contest here.

• Samsung ST95: Plastic ultracompact body, no weather sealing.
• Sony A7S II: Magnesium alloy body, weather resistant (dust & moisture resistant).

The Sony can withstand challenging outdoor environments - crucial for landscape, wildlife, and travel photographers. The ST95 is vulnerable to elements and not designed for rugged use.
