Choosing a camera is never a simple task, especially when differing categories, sensor sizes, and intended uses come into play - as is the case with the Panasonic Lumix DC-GH5S and the Samsung MV800. Both cameras cater to notably different segments of the photography spectrum, yet the contemporary enthusiast or professional often wrestles with the dilemma of high-end pro mirrorless systems versus convenient compact shooters.

Having logged thousands of hours testing cameras across genres - from landscape to wildlife photography - I’m well placed to dissect these two models’ capabilities, real-world performances, and value propositions, offering readers actionable insights to guide their next camera investment.

First Impressions: Size, Build, and Ergonomics

The Panasonic GH5S showcases a traditional SLR-style mirrorless body, designed for professional handling and durability, whereas the Samsung MV800 is a sleek, pocketable compact with a radically smaller footprint. As visualized above, the GH5S’s robust 660g frame - measuring 139x98x87 mm - commands your presence and invites a firm grip, benefiting extended shooting sessions and tough conditions. In contrast, the MV800 tips the scales at just 121g and stretches a mere 10 mm thick, making it ultra-portable and easy to slip into a jacket pocket or purse.

While portability favors the MV800, it comes at the compromise of limited manual grip and control customization - the GH5S offers an ergonomic advantage with dedicated dials, buttons, and a thoughtfully laid out control scheme optimized for professional workflows.

Handling and User Interface: For Precision or Convenience?

From a handling standpoint, the GH5S distinctly appeals to users who demand precision and speed, marked by an array of physical controls on its top deck - shutter speed, ISO, exposure compensation dials - and an illuminated (though subtle) button layout that ensures quick access in dimly lit environments. The articulated 3.2-inch touchscreen further aids framing flexibility across diverse shooting angles.

Conversely, the MV800 adopts a simple minimalistic top plate, with limited physical control and a polished tilting 3-inch display designed primarily for quick shoots and seamless sharing. Its touchscreen interface caters well to casual shooters but lacks the depth and responsiveness expected by photography professionals seeking granular control. Notably, the MV800 does not feature a viewfinder, relying solely on its LCD for composition, a stark contrast to the GH5S's high-resolution electronic viewfinder boasting approximately 3.68 million dots and 100% coverage - the latter critical for accurate framing in bright environments or sports photography.

Sensor Technology and Image Quality: The Core Differentiator

Herein lies the most dramatic divide: the GH5S’s large Four Thirds (17.3 x 13 mm) CMOS sensor boasting 10.2 megapixels versus the MV800’s significantly smaller 1/2.3-inch (6.17 x 4.55 mm) CCD sensor with 16 megapixels. The GH5S excels in pixel size, low-light handling, and dynamic range because of its larger surface area and back-illuminated sensor design. Despite having a “modest” resolution by modern standards, the GH5S trades megapixels for enhanced sensitivity allowing remarkable ISO performance up to 204800 (boosted) and a native max ISO of 51200, caters to videographers and photographers demanding excellent noise control in challenging conditions.

The MV800’s sensor, although higher resolution on paper, suffers from the inherent limitations of compact fixed lens systems, lacking raw support entirely and maxing out at ISO 3200. Compact sensor noise, dynamic range compression, and limited post-processing latitude make it a tool best reserved for casual daylight photography or snapshots.

Autofocus Systems Put to the Test: Speed, Accuracy, and Reliability

The GH5S employs a 225-point contrast-detection autofocus system with advanced face detection and tracking capabilities optimized for video and stills alike, including continuous AF and eye tracking (for humans), although it lacks animal eye AF detected in contemporary competitors. Panasonic’s “DFD” technology (Depth From Defocus) improves AF speed, especially under consistent lighting conditions, offering reliable performance during sports and wildlife shooting. My hands-on evaluations confirm consistent AF accuracy even under subdued ambient light, pairing well with the 12 fps burst shooting mode - a considerable merit for action photographers.

In stark contrast, the MV800’s autofocus configuration is rudimentary. It relies solely on contrast detection with limited focus areas and no continuous or predictive tracking, severely impairing its ability to capture fast-moving subjects efficiently. AF speed is noticeably slower, and the absence of raw support further limits post-shoot corrections.

Display and Viewfinders: Composition and Accessibility

The Panasonic GH5S features a versatile, 3.2-inch fully articulating touchscreen LCD with a 1620k-dot resolution, enabling photographers to shoot from challenging angles - useful for macro, video, or street photography. The touch interface is responsive, intuitive, and integrates seamlessly within the ergonomic control scheme. Additionally, the GH5S provides a customizable EVF boasting 0.76x magnification and 100% frame coverage, ensuring accuracy in composition irrespective of environmental lighting.

The Samsung MV800 is equipped with a 3-inch tilting LCD with a 460k-dot resolution - respectable for its category and period - but lacks an EVF, which is a significant disadvantage in bright outdoor scenarios due to screen glare. While its touchscreen offers basic functionality, it cannot match the GH5S’s comprehensive touch control or viewing experience.

Lens Ecosystem and Compatibility: Building Your Creative Arsenal

The GH5S’s Micro Four Thirds mount opens access to a mature lens ecosystem, supporting over 100 lenses from Panasonic, Olympus, and third-party manufacturers, ranging from ultra-wide, high-speed primes, to telephoto super-telezooms. This diversity empowers photographers to tailor their gear precisely - from intimate portraits to expansive landscapes and long-reach wildlife shots - maximizing creative versatility.

The MV800’s fixed zoom lens (26-130mm equivalent F3.3-5.9) precludes any lens swapping and thus is constrained to the built-in zoom range with variable and relatively slow apertures unsuitable for professional-grade bokeh or low-light shooting.
