Panasonic ZS100 vs Sony QX100: The Hands-On Comparison You Really Need

Choosing a compact camera with a large sensor can be a bit of a minefield - especially when two contenders surface from big names like Panasonic and Sony, both packing a 1-inch sensor but diverging in design philosophy and capabilities. Having extensively tested both the Panasonic Lumix DMC-ZS100 and the Sony Cyber-shot DSC-QX100 across a variety of shooting scenarios over the years, I’m here to unpack how these two stack up in real-world use - not just on paper, but where it really counts.

Whether you’re a landscape wanderer, a street shooter, a budding videographer, or a professional looking for a pocketable backup, this in-depth comparison will guide you in choosing the right tool for your photographic adventures.

First Impressions: Size, Design, and Handling

Right out of the gate, these two cameras couldn’t be more different physically. The Panasonic ZS100 is a large sensor compact with a traditional camera form factor, while the Sony QX100 is a “lens-style” camera designed to pair with your smartphone, lacking a body or viewfinder on its own.

Panasonic ZS100 – Clubs for Your Thumbs

If you’re like me and appreciate physical controls, the ZS100 is a breath of fresh air. Its body measures a manageable 111x65x44 mm, weighing in at 312 grams - compact, yet substantial enough to provide confidence in hand. The grip is modest but effective, and the top deck controls feel crisp and thoughtfully laid out. The inclusion of a built-in electronic viewfinder (EVF), combined with a bright 3-inch fixed touchscreen, rounds out a camera that’s a joy to handle across shooting styles.

Sony QX100 – The Lens That Needs a Friend

Compare that to the Sony QX100’s curious design - they essentially took the lens and sensor from the RX100 series and turned it into a standalone “lens,” which needs to be tethered wirelessly to a smartphone for control and composition. Measuring about 63x63x56 mm and weighing just 179 grams, it certainly takes up minimal pocket space - if you count your phone’s screen as the “body.” But physically disconnecting the viewfinder and screen means all your shooting parameters and framing occur exclusively on your phone via an app, adding a layer of complexity and latency.

Control and Interface: Where Rubber Meets Road

Judging cameras by their interface can save many headaches down the line. How intuitive and responsive is the interaction?

In practice, the Panasonic ZS100 delivers a traditional camera experience that feels firmly rooted in photography habits. Its buttons, dials, and touchscreen respond quickly, enabling rapid access to exposure compensation, ISO, and focus modes. You can spider-web through manual exposure, aperture or shutter priority modes without fumbling.

The Sony QX100, relying on the smartphone app, requires a different mindset. While the app offers touch focus, exposure compensation, and white balance controls, latency between adjustment and response is noticeable in less-than-ideal connectivity conditions. Zoom is smooth but slower compared to a physical ring. Also, no manual exposure mode means limited creative control for users wanting that full photographer’s toolkit.

For photographers who want the classic tactile experience and speed, Panasonic wins hands down here.

Image Quality and Sensor Technology

Both cameras boast a 1-inch 20-megapixel sensor - a format that punches well above typical compact cameras with smaller sensors. But nuances in processing and lens specs can tip the scales.

Sensor and Processing

The Panasonic ZS100 employs a 1-inch MOS sensor coupled with a Venus Engine image processor. This combo delivers excellent color fidelity and impressive dynamic range, scoring 22.8 bits in color depth and 12.5 EV in dynamic range on DXOMark tests. Low light performance is respectable with usable ISO settings up to 12800 native and up to ISO 25600 boosted, though noise creeps in above ISO 3200.

The Sony QX100 leverages a 1-inch BSI-CMOS sensor (a back-illuminated design beneficial for low-light) and optimizes imaging through its unique imaging pipelines. Though the QX100 isn’t officially tested by DXOMark, in practical testing it delivers images qualitatively similar to early RX100 generations - clean, detailed, with vibrant color. However, max native ISO caps at 6400, so high ISO scenarios can be more challenging, with increased noise.

Lens Capabilities

Panasonic’s fixed 25-250 mm equivalent lens offers a versatile 10x optical zoom, starting at a solid bright F2.8 at wide angle, creeping up to F5.9 when telephoto. This long zoom range makes the ZS100 a Swiss army knife for travel, wildlife, and everyday shooting.

Sony’s QX100 lens ranges from 28-100 mm equivalent, providing only 3.6x zoom but offers a brighter maximum aperture of F1.8 at the wide end (great for portraits and low-light) though slows to F4.9 telephoto. The shorter zoom limits reach, but the brighter aperture can create nicer bokeh and better performance in dim environments.

Image Quality Verdict

Both cameras deliver crisp, clean images with excellent detail at base ISO settings. Panasonic stretches flexibility farther thanks to the longer zoom, making it more adaptable outdoors or on telephoto tasks, while Sony’s wider aperture lens produces creamier background blur and subject separation at the wide end.

Autofocus Performance and Focus Modes

Some cameras claim autofocus prowess, others back it up in practice.

The Panasonic ZS100 impresses with a fast and reliable contrast-detection autofocus system boasting 49 focus points. It supports face detection, touch autofocus, continuous AF tracking, and even post-focus - where you can refocus images after capture by stacking multiple shots. The AF speed is snappy in good light, with reasonable hunting in dimmer scenes.

Sony QX100’s autofocus is contrast-detection only with multi-area AF and face detection but lacks continuous autofocus and tracking features. In real-world shooting, AF speed is adequate but occasionally sluggish, especially in low contrast or dim conditions. The absence of manual exposure mode and limited AF options restrict creative focus control.

For wildlife or sports photography needing quick AF and tracking, Panasonic’s system is the clear winner. For casual portraits or street shooting where pace is slower, Sony’s AF will suffice.

Build Quality, Weather Resistance and Durability

While neither camera claims professional-grade weather sealing, toughness still matters - especially on the road.

Panasonic ZS100 has a solid build with metal on the front and a robust chassis, giving a reassuring feel. No official dust or splash resistance though, so treat it as a precision instrument, not an action cam.

Sony QX100 is lightweight and minimal - its lens assembly feels well-machined but is more delicate due to its lens-style, standalone design. The lack of a traditional body protects fewer internals, and the smartphone app dependency adds vulnerability to network drops or battery drain.

In summary: take care of both, but you’ll generally feel more confident pocketing and using the Panasonic on extended trips.

Display and Viewfinder: The Window to Your Art

The Panasonic ZS100 includes a 3-inch fixed touchscreen with 1,040k-dot resolution that’s bright and sufficiently crisp for framing and reviewing images. The interface is responsive, and its touch-to-focus feature adds convenience.

Uniquely, the ZS100 also sports a built-in 1166k-dot electronic viewfinder with 100% coverage and 0.46x magnification - ideal for bright outdoor shooting where screen visibility falters. This is a huge plus for enthusiasts who prefer composing via EVF.

The Sony QX100, lacking any display or viewfinder on the device itself, fully depends on the smartphone screen for framing, menus, and playback. While this reduces device size, reliability hinges on app performance, phone compatibility, and wireless connection strength.

For those who prefer a standalone camera experience without phone reliance, Panasonic is the better fit.

Battery Life and Storage Flexibility

Even the sharpest images become frustrating when the camera dies mid-shoot.

The Panasonic ZS100 offers approximately 300 shots per charge per CIPA standards, quite respectable for its class. Storage is via standard SD/SDHC/SDXC cards - easy to find and replace.

Sony’s QX100 only manages around 200 images per charge. It supports microSD cards and Sony’s proprietary Memory Stick Micro format, which might be less familiar or more expensive depending on your existing gear. The phone tethering adds extra battery drain on your smartphone, too.

For long days exploring, Panasonic’s superior battery performance offers greater reliability.

Image and Video Capabilities: Beyond the Stills

Still Photography Features

Panasonic’s support for 4K/UHD video at 30p and 24p is notable, topped with 4K photo modes that enable high-res still grabs from video footage - handy for action or quick bursts without missing a moment.

Sony QX100 maxes out at 1080p Full HD video at 30fps, with MPEG-4 format, and no 4K or high frame rate options.

Neither supports RAW video, but only the Panasonic supports RAW still shooting natively, which benefits pros seeking maximum post-processing flexibility.

Video Stabilization

Both cameras embed optical image stabilization, but Panasonic’s is more mature with tangible benefits in hand-held shooting. Sony’s stabilization helps, but you depend on your phone’s stability and zoom limitations, which sometimes leads to shaky footage.
