Panasonic GH5S vs Sony QX100: A Hands-On, In-Depth Camera Comparison for Enthusiasts and Professionals

In the ever-evolving world of digital cameras, it’s both exhilarating and challenging to select the right tool amid a sea of technical specifications and marketing jargon. Having spent over 15 years rigorously testing countless cameras across genres - from intimate portraits to demanding wildlife shoots - I’ve learned that the real-world performance and user experience trump raw specs every time. Today, I’m thrilled to share my extensive comparison between two very different but compelling cameras: the Panasonic Lumix DC-GH5S and the Sony Cyber-shot DSC-QX100.

These models represent distinct philosophies and eras. The GH5S is a professional-grade Micro Four Thirds mirrorless powerhouse, designed with video creators and serious photographers in mind. The QX100, now a vintage lens-style compact, offers an innovative concept that married smartphone convenience with a large 1-inch sensor and fixed zoom lens. While seemingly apples-to-oranges, this comparison offers a fascinating look at how camera design and technology serve diverse creative needs.

Getting a Feel: Size and Ergonomics on the Body

Let’s start where my testing always begins - handling the camera in real shooting scenarios. The Panasonic GH5S is a substantial, robust mirrorless camera with SLR-style ergonomics that accommodate extended shooting comfortably. It weighs in at 660 grams and measures 139 x 98 x 87 mm, providing a firm grip for stability during handheld shots. In contrast, the Sony QX100’s lens-style design is strikingly compact and minimalistic at just 179 grams and about 63 x 63 x 56 mm, designed to be clipped onto a smartphone or used standalone - ideal for casual, on-the-move photography.

The GH5S’s physical size supports intuitive manual control with a wealth of buttons and dials, making it a photog’s joy during fast-paced shoots. The Sony QX100 relies entirely on your smartphone for control since it lacks a built-in viewfinder or display, which impacts usability for traditional photography styles.

From my experience, the GH5S’s handling is that of a professional tool made for hours of use without fatigue, while the QX100 impresses as a highly portable, pocketable device for spontaneous moments.

Top View and Control Layout: Putting You in the Driver’s Seat

As a photographer, I value ergonomic design that prioritizes quick settings access, especially in fast-changing light or action. The GH5S top panel reveals a sophisticated, logically placed array of dials, an ISO dial cleverly integrated top-left, and a dedicated video record button - no surprises, just deliberate professional design. The QX100's top is sparse, with fewer physical controls since shooting settings are smartphone-driven.

Sliding between aperture priority, shutter priority, and manual exposure on the GH5S feels seamless and rewarding; live view information displayed on its electronic viewfinder lets me confirm exposure and focus swiftly. On the QX100, all adjustments require smartphone interaction, which can introduce a software-learning curve and occasional latency.

If you prefer tactile, direct control over exposure, shutter speed, and focus, the GH5S’s interface stands far apart in usability.

Diving Into Sensor Technology and Image Quality

Here’s where their respective shooting potentials truly diverge. The GH5S sports a 10.2 MP Four Thirds sensor (17.3mm x 13mm), omitting the anti-aliasing filter to maximize sharpness - a design choice emphasizing video and low-light still performance. Meanwhile, the QX100 features a 20.2 MP 1-inch BSI-CMOS sensor (13.2mm x 8.8mm) with a conventional anti-aliasing filter, optimized for still imagery and portability.

In my side-by-side tests of daylight captures, the GH5S’s lower megapixel count results in files that emphasize dynamic range and noise control, performing exceptionally well at ISOs as high as 51200 native (boosting to 204800). Shadows retain detail impressively, and highlight roll-off is smooth - a boon for landscape and night shooters.

Conversely, the QX100 delivers higher resolution stills ideal for prints and cropping flexibility, but falls short in dynamic range and noise suppression at ISOs above 1600. This significantly limits its use in tricky lighting, though the wide aperture lens (f/1.8-4.9) aids in gathering light.

For shooting portraits, the GH5S’s sensor, combined with its 225 autofocus points and face detection, renders skin tones naturally with subtle gradations and excellent highlight retention. The QX100’s smaller sensor can struggle to deliver equally rich tonality, though its fast lens helps isolate subjects nicely for shallow depth-of-field effects at telephoto focal lengths.

Viewing Experience: Display and Interface Differences

Neither camera surprises in the electronic viewfinder department: the GH5S is equipped with a high-resolution 3.68M-dot EVF covering 100% frame, a critical tool I've come to rely on for precise manual focusing and exposure evaluation.

The QX100 lacks an EVF entirely, depending wholly on the connected smartphone’s screen for composition and settings. This is a cool idea, but I found it limiting in bright daylight conditions since smartphone screens can wash out quickly, frustrating outdoor shooting.

The GH5S features a fully articulated 3.2-inch touchscreen ideal for low-angle, overhead, or video framing. Touch controls enable focus point selection and quick menu navigation. The QX100 offers no rear screen but depends on the phone’s touchscreen, adding to its versatility if the smartphone app is responsive.

For users who crave a dependable display and EVF combo to nail focus and framing in diverse shooting environments, the GH5S is superior.

Shooting Styles: Who Wins in Each Genre?

While camera specs and sensor sizes tell part of the story, exploring actual photography categories reveals the nuanced strengths and weaknesses of each tool.

Portrait Photography

The GH5S shines here with its keen face detection AF, eye detection capabilities, and excellent color depth performance. During studio and natural light portrait sessions I conducted, the camera produced creamy bokeh backed by excellent edge sharpness and gorgeous skin tone reproduction - even in challenging lighting.

QX100’s lens (28-100 mm equivalent) allows framing flexibility, but the smaller sensor limits bokeh smoothness and tonal depth. Also, autofocus hunting was noticeable on my model when shooting close-ups under low light, though sufficiently sharp in well-lit conditions.

Landscape Photography

Landscape shooters will appreciate the GH5S’s broad dynamic range and excellent highlight/shadow handling. Its weather sealing means I confidently shot coastal scenes while battling wind and spray, a test where the delicately engineered GH5S body felt reassuring.

Though the QX100’s larger pixel count (20 MP) aids in detail retrieval, its limited weather resistance and narrower dynamic range capped my evolving landscape compositions.

Wildlife and Sports Photography

The GH5S supports 12fps continuous shooting - a rate I tested in sequences of moving birds and athletes - with reliable autofocus tracking. Contrast-detection AF can lag behind phase-detection systems on higher-end bodies, but the GH5S manages well with its 225 focus points and customizable AF modes.

On the other hand, the QX100 lacks continuous shooting and tracking features strong enough for wildlife or sports action, affirming its place as a casual snapper rather than a professional’s fast-action camera.

Street and Travel Photography

Sony’s lens-style QX100 is compact and virtually invisible, great for capturing candid street scenes without intimidating subjects. However, the tethered operation to a smartphone may slow reactive shooting.

For travel, the GH5S is heavier but offers versatility in lenses and settings, commanding respect for durability and battery life (440 shots per charge vs. the QX100’s 200). The dual card slots on the GH5S add peace of mind on long journeys.

Macro and Night/Astro Photographers

The GH5S supports focus bracketing and stacking, unique features I exploited during macro work to extend depth of field dramatically without losing detail. Its high native ISO and push-boost modes enable starry night shots where sensor noise is minimal.

The QX100’s minimum focus distance of about 5cm and optical stabilization help in macro-ish shots but lack dedicated focus bracketing or stacking support. Night shooting is limited by sensor noise and no manual exposure mode, reducing creative astrophotography options.

Video Capabilities

Video is where the GH5S truly flexes its muscles: shooting 4K DCI at 60p with 10-bit 4:2:2 internal recording, HDMI output, and professional audio ports. I tested extended takes and found the camera’s heat management and color profiles ready for professional workflows.

The QX100 records only Full HD 1080p at 30fps with MPEG-4 compression - adequate for casual clips but far from professional use.

Build Quality, Weather Resistance, and Durability

Solid build quality and weather sealing are critical for professionals - and the GH5S delivers with a magnesium alloy body that feels rugged and resistant to dust and splash, supporting real-world reliability in harsh environments I tested it in.

The Sony QX100 is plastic-bodied, not weather-sealed, suited for occasional fair-weather shooting.

Lens Ecosystem and Compatibility

The GH5S employs the Micro Four Thirds mount, boasting a mature lens lineup with over 100 lenses from Panasonic, Olympus, and third parties - ranging from ultra-wide primes to fast telephotos with image stabilization.

The QX100 lens is fixed and incapable of interchangeability, limiting creative flexibility but reducing bulk.

Battery Life and Storage

In field shoots I logged, the GH5S’s 440-shot battery life proved ample, supported by two UHS-II card slots allowing overflow and backup. The QX100’s 200 shots per battery charge leaves less room for extended use, and single microSD card compatibility offers fewer storage safeguards.

Connectivity and Wireless Features

The GH5S includes Wi-Fi, Bluetooth, HDMI, USB 3.1, microphone and headphone jacks - catering fully to professionals integrating cameras into complex workflows.

The QX100 connects wirelessly via Wi-Fi and NFC to smartphones, enabling convenient image transfer but with less robust connectivity overall.

Price and Value Assessment

At launch, the GH5S retailed near $2500, positioning it firmly as a pro video and photo hybrid. The QX100, priced around $268, is an affordable entry into advanced compact imaging.

For photographers prioritizing advanced video, rugged build, and expansive lens choices, the GH5S delivers value commensurate with its cost.

The QX100 appeals to casual shooters wanting a significant upgrade over a smartphone camera without bulk or complexity.

Sample Images: Visual Proof of Performance

Examining real-world images further clarifies distinctions. The GH5S produces richly detailed landscapes with muted noise and deep shadows; portraits exhibit smooth bokeh and accurate colors. The QX100 images are pleasantly sharp for a compact, with decent color in good light but visible noise and less highlight retention in shadows.
