Panasonic GX85 vs. Pentax WS80: A Real-World Face-Off From a Seasoned Camera Tester

When hunting for a camera, it's easy to get dazzled by specs sheets or swayed by brand loyalty alone. But after having wrangled both the Panasonic Lumix GX85 and the Pentax Optio WS80 through my extensive hands-on testing sessions, I’m here to provide you with a grounded, no-fluff comparison. These two cameras could not be farther apart in design philosophy and purpose, yet each carves out its niche well - if you know what you want. This article will assess their strengths, weaknesses, and real-world value across photography disciplines, guiding enthusiasts and pros alike to a confident buying decision.

Size, Feel, and Control: How They Sit in Your Hands Matters

First impressions matter. Weight, grip ergonomics, button layout - all these contribute to how intuitively you can operate a camera, especially during extended shoots.

The Panasonic GX85 is a classic rangefinder-style mirrorless camera with a thoughtfully designed magnesium alloy body. It boasts a robust build yet maintains a modest footprint. At 122 x 71 x 44 mm and weighing 426 grams (battery included), it strikes a nice balance between portability and solid feel.

In contrast, the Pentax WS80 is a tiny waterproof compact measuring 92 x 60 x 22 mm and just 125 grams. This difference is nearly threefold in weight and reveals the WS80’s clear intent as a pocket-friendly, rugged point-and-shoot device.

The Panasonic’s top deck layout, complete with dedicated dials for shutter speed and exposure compensation, makes manual control a joy and enables quick adjustments on the fly. The Pentax has a barebones control scheme, offering minimal manual exposure options - it’s a “point and shoot” through and through.

If you’re the type who likes “clubs for thumbs” - buttons and dials you can program and feel without looking - the GX85 is your best friend. But if you want something to toss in your wet gear bag or beach pocket, the WS80’s size and splashproofing will win points.

Bottom line: For ergonomics and control comfort, Panasonic GX85 is the winner by a mile. The WS80 is about convenience and durability, not tactile feedback.

Sensor Technology and Image Quality: Where the Real Differences Reside

The silent star of any camera is its sensor, so let's geek out a bit on the silicon.

The GX85 uses a 16MP Four Thirds CMOS sensor sized 17.3 x 13 mm (about 224.9 mm²). It’s paired with Panasonic’s Venus Engine processing, handles ISO up to 25,600, and critically, omits an optical low-pass filter (OLPF), enhancing sharpness and resolving power. The sensor has contrast-detection autofocus points numbering 49, a good spread for versatility.

The WS80 sports a tiny 1/2.3” CCD sensor, measuring just 6.17 x 4.55 mm (~28 mm²) with a modest 10MP resolution, plus an antialiasing filter. Its max ISO is 6400, but despite the higher ISO rating, noise floor and dynamic range will be visibly inferior compared to the GX85.

Let’s put this into perspective visually:

In side-by-side tests, the Panasonic GX85’s files show more dynamic range to rescue highlights and shadows - a critical advantage for landscape and wedding photographers. The lack of antialiasing filter yields crisper images, important for portraits and macro where fine detail matters.

The WS80’s sensor is simply toyish by comparison, producing images suffused with noise beyond ISO 800 and lacking in tonal gradation at the edges of exposure. It won’t challenge the GX85 in any technical measure of image quality, but its sensor is a practical compromise for underwater or outdoor adventures where ruggedness trumps pixel peepability.

LCD and EVF: The Window to Your World

Software developers and engineers put a lot of thought into the display and viewfinder - these are your eyes when composing shots or reviewing results.

The GX85 sports a 3-inch tilting touchscreen LCD at 1040k dots resolution, plus a high-res electronic viewfinder (EVF) at 2764k dots covering 100% frame. The tilt allows creative angles, macro, and vlogging applications. The touchscreen responsive and supports various touch-based controls, speeding up settings changes.

The WS80, consistent with its compact class, features a fixed 2.7-inch screen with just 230k dots and no EVF at all. Low resolution and fixed orientation mean struggles under direct sunlight and constrained framing flexibility.

If you do any serious composition - street photography, landscapes, portraits - the GX85’s bright, articulating, and touch-enabled screen, alongside the sharp EVF, is transformative.

Autofocus and Speed: Tracking Your Action

Fast and accurate autofocus is a make-or-break feature for sports, wildlife, and event shooters.

The GX85 employs contrast-detection autofocus over 49 points, featuring face detection, tracking, and selectable AF areas. While lacking phase-detection pixels (PDAF) on sensor, the GX85 autofocus performs admirably for a contrast-based system, with subject tracking competent enough for casual sports or wildlife.

Burst speed tops out at 8fps with continuous autofocus - a respectable figure for its class.

The WS80 has a much more rudimentary AF system: 9 focus points, fixed center priority, contrast detection only, and no tracking or face detection. Moreover, continuous shooting is limited to a snail’s pace of 1fps. It’s clearly not meant for action photography.

This difference extends into video AF as well - the GX85’s faster, smoother autofocus makes it viable for run-and-gun shooters, while the WS80 lags behind considerably.

Image Stabilization and Exposure Modes

The GX85 shines with sensor-based 5-axis image stabilization, which combats shake from yaw, pitch, and even roll axes and is invaluable for handheld macro, low-light walks, or video shooting.

The WS80 misses on stabilization altogether, counting instead on optical lens construction and its rugged shell.

Regarding exposure control, the GX85 offers full manual control, shutter and aperture priority, exposure compensation, custom white balances, bracketing, and even focus bracketing for stacking macro shots. All these tools allow the photographer to creatively sculpt images.

The WS80, conversely, is a point-and-shoot device with no manual exposure modes or exposure compensation. While it offers some white balance choices and limited flash control, it’s a camera that mostly does what it wants.

Lens Ecosystem: Flexibility vs. Fixed Convenience

Because the GX85 is Micro Four Thirds mount, it enjoys access to a massive catalog of lenses from Panasonic, Olympus, Sigma, and others - over 100 lenses covering everything from fisheye to super-telephoto macro.

The WS80 has a fixed zoom lens covering a 35-175mm equivalent focal range (5x zoom) with max apertures of F3.8-4.7 - decidedly slow, but acceptable given the compact, sealed design.

The variety and quality of lenses you can pair with the GX85 is a game-changer if you’re an enthusiast or professional seeking specialty glass. Meanwhile, the WS80 lens is satisfactory for casual snapshots and travel where changing lenses in the field could be a liability.

Durability and Environmental Toughness

If you work outdoors, the Pentax WS80 is explicitly designed for rugged environments - waterproof to 10m, dustproof, and shock resistance to an extent (though lacking shockproof certifications). This means happy snorkelling, beaching, and hiking in adverse weather without worrying about gear failure.

The Panasonic GX85 lacks any environmental sealing and must be handled with care in wet or dusty conditions.

Battery Life and Storage

Battery life is a modest 290 shots per charge on the GX85, roughly in line with mirrorless standards but on the lower side compared to DSLRs. The WS80’s battery specifics are murky, but given its modest sensor and LCD demands, plus dedicated D-LI68 battery, expect it to last around 200-300 shots on average.

Both cameras support a single SD/SDHC/SDXC card slot, which is standard fare.

Video Capabilities in Action

The GX85 supports 4K UHD video at 30p and 24p, plus Full HD 1080p at 60p, including 4K photo mode that allows extraction of high-res stills from video frames. Video output is clean via HDMI, although audio input is limited (no mic or headphone jacks), somewhat restricting professional-grade production.

The WS80 can only manage 720p HD video at 30fps using Motion JPEG format and has no advanced video features.

Moreover, Panasonic’s in-body stabilization dramatically improves handheld video smoothness, something the WS80 cannot offer.
