Panasonic Lumix SZ5 vs Pentax Optio WS80: An In-Depth Compact Camera Comparison

In my 15+ years testing cameras - from pro DSLRs to rugged compacts - I’ve encountered a surprising range of small sensor compacts that punch well above their weight. Today, I’m putting two such stalwarts head-to-head: the Panasonic Lumix DMC-SZ5 (simply Panasonic SZ5) and the Pentax Optio WS80. Both were released in the early 2010s targeting casual yet capable shooters, but each adopts a distinctly different philosophy - the SZ5 focusing on zoom versatility and image stabilization, while the WS80 boasts a rugged, waterproof build.

In this comprehensive hands-on review, I’ll break down their strengths, weaknesses, and real-world capabilities across a wide range of photographic genres, from portraits to astrophotography. I also draw upon my experience with similar sensor tech, optics, and camera ergonomics to give you an informed perspective on which compact might fit your workflow best.

Let’s dive in.

First Impressions and Ergonomics: Handling in the Field

I place a premium on a camera’s physical feel since no tech spec can replace how well a camera fits your hands during long shooting sessions.

Panasonic SZ5 (left) and Pentax WS80 (right) size comparison with dimension overlay.

Physically, the Panasonic SZ5 feels slightly slimmer and more streamlined, measuring 104x58x21 mm and weighing 136 grams. Its longer zoom lens pushes the body length out noticeably, but the camera remains relatively pocketable. The Pentax WS80, by contrast, is a bit chunkier at 92x60x22 mm and slightly lighter at 125 grams, thanks mainly to its rugged sealing.

The Panasonic’s lens extends more significantly with a 10x zoom (25-250mm equivalent) compared to the Pentax’s 5x zoom (35-175mm), which somewhat affects the SZ5’s balance when handheld but rewards you with extra reach.

Control layouts are compact and minimal on both cameras, with no dedicated dials for aperture or shutter speeds - they’re designed primarily for auto-oriented users rather than manual fiddling. However, the Panasonic's slightly larger grip and well-placed shutter button provide a tad more confidence for one-handed shooting.

The tough waterproof construction of the Pentax WS80 speaks to a different use case entirely - it’s built to survive splashes, dust, and rougher handling. For travel or adventure shooters prioritizing durability, this can be a game changer.

Sensor and Image Quality: The Heart of the Matter

Both cameras use a 1/2.3-inch CCD sensor, a standard size among compacts, which inherently limits low-light performance but keeps costs and size down. The SZ5 edges out with a higher resolution at 14 megapixels versus the WS80's 10 megapixels. That difference translates into mildly crisper crops and more detail in daylight photos.

Comparative imaging sensor metrics and resolutions.

However, larger pixel count isn’t always better. The Pentax’s slightly larger sensor surface area (28.07 mm² vs 27.72 mm² for Panasonic) can offer marginally improved light gathering efficiency per pixel. Still, the CCD sensor technology in both cameras limits dynamic range and noise performance at high ISOs compared to contemporary CMOS sensors.

In practice, both cameras produce respectable daylight and outdoor images, with the Panasonic showing slightly improved detail preservation, especially wide open at the longer focal lengths. Color reproduction leans toward neutral and natural on both, although the Pentax’s photos exhibit a subtle warm tint that can be charming for portraits.

Unfortunately, neither camera supports RAW shooting, locking you into JPEG files. The SZ5 lacks exposure compensation or manual modes, so fine control over highlight/shadow detail is limited. The WS80 provides manual focus - rare in this niche - but no shutter or aperture priority modes.

If image quality is your chief concern and you demand ultimate control, these compacts won’t replace enthusiast or professional mirrorless systems. But for casual users or travel snapshots, they stand up surprisingly well.

User Interface and Controls: Comfortable or Clunky?

The Panasonic SZ5 (left) features a slightly larger 3-inch fixed LCD compared with the Pentax WS80’s 2.7-inch screen.

Both models have modest TFT LCDs with 230k-dot resolution, falling short of today’s high-res displays. The Panasonic SZ5's 3.0-inch screen provides a bigger, slightly clearer live view with no touch functionality, while the smaller 2.7-inch screen on the Pentax WS80 offers marginally less immersive shooting feedback.

Neither sport viewfinders - optical or EVF - so relying on the rear LCD for composition is mandatory. This limits usability in bright daylight, especially prone to glare. I found the SZ5’s screen slightly easier to see outdoors due to its larger size and better contrast.

Menu navigation remains straightforward yet basic on both. The Panasonic SZ5 lacks customizable buttons or quick-access function dials, which slows down shooting adjustments. The Pentax WS80 fares similarly but benefits from the option of manual focus adjustments - a noteworthy plus for close-ups or macro shots where contrast-detection AF can struggle.

Live view autofocus methods differ: the Panasonic uses contrast detection with 23 focus points and includes face detection, which works reasonably reliably. The Pentax is skinnier on focus area options with nine points and no face detection support, pointing to a more rudimentary AF system.

Lens Versatility and Macro Capabilities

If telephoto reach is a priority, the Panasonic SZ5’s 10x zoom (25-250mm equivalent at f/3.1-5.9) is a significant advantage over the Pentax WS80’s 5x range (35-175mm at f/3.8-4.7). This flexibility lets you frame distant wildlife or landscape details far more easily without changing lenses (which neither can do, of course).

The SZ5 also impresses with optical image stabilization - an essential aid when shooting at long focal lengths handheld. The Pentax WS80 does not have image stabilization, so expect more blurry shots when zoomed in or in low light.

Both cameras support macro shooting. Panasonic’s minimum focus distance is a tight 5cm at wide-angle, letting you capture fine detail close ups. The Pentax does not specify macro performance clearly but offers manual focusing, which can help critical focus placement at close range.

For flower, insect, or product photography, I found the SZ5’s macro capabilities more consistent and versatile in everyday use.

Autofocus Performance and Burst Shooting: Catching the Moment

Modern action and wildlife shooters demand fast, accurate autofocus and high burst rates to ensure sharp captures of fleeting moments.

Looking down at the control spread highlights each camera’s ergonomics and button configurations.

Here, both models reveal clear limitations:

• The Panasonic SZ5 lays claim to continuous autofocus and decent tracking with 23 AF points and face detection that works acceptably in good lighting. However, its burst speed is only around 2 frames per second, which isn’t ideal for sports or fast wildlife.

• By contrast, the Pentax WS80 offers just single AF and no continuous tracking, with a 1 fps burst speed. This drastically limits its usefulness for dynamic subjects.

Neither camera supports advanced focusing tech such as phase-detection AF, nor do they have sophisticated prediction algorithms found in DSLR or mirrorless systems.

For static subjects or controlled environments like portraits or still-life, both AF systems hold up fine. But for active wildlife, sports, or street photography demanding quick reflexes, they fall short.

Durability, Weather Sealing, and Travel Readiness

If you travel frequently or shoot outdoors in variable conditions, ruggedness and weather sealing are key.

Here the Pentax Optio WS80 clearly leads. It is waterproof, dustproof, and shock-resistant (to an extent), making it ideal for poolside snaps, beach outings, or light hikes in misty weather. It’s not freeze-proof or crush-proof, but the ruggedized compact category is niche enough.

The Panasonic SZ5, meanwhile, lacks environmental sealing and shouldn’t be exposed to rain or heavy dust.

Perhaps surprisingly, battery life favors the Panasonic SZ5 (rated at about 250 shots per charge) over the WS80 (battery life unspecified but generally lower due to smaller battery packs in rugged compacts). I found I had to carry spares for the Pentax during extended trips.

The SZ5 offers built-in wireless connectivity - useful to speed image transfers to phones or social media - whereas the WS80 has no wireless features.

Video Capabilities: Which Compact Films Better?

For casual video, neither camera transforms your filmmaking but they do enable straightforward HD capture.

• The Panasonic SZ5 records video in MPEG-4 at 1280x720 pixels at 30 fps max resolution - a respectable standard circa 2012, with basic optical image stabilization support.

• The Pentax WS80 also captures 720p video but uses Motion JPEG encoding, which results in larger file sizes and somewhat lower compression efficiency.

Neither camera offers 4K or advanced video options such as microphone inputs, headphone jacks, or slow-motion modes. Internal stabilization on the SZ5 gives it an advantage for smoother handheld clips.

If you prioritize casual video alongside stills, the Panasonic holds a practical edge.

Subject-Specific Performance Snapshot: Portraits to Astrophotography

Time to break down how each camera performs in common photo genres I test regularly:

Build Quality, Connectivity & Storage: Practical Working Considerations

Both cameras use SD card slots with SDHC/SDXC compatibility, making storage upgrades easily manageable.

Connectivity-wise, the Panasonic SZ5 includes built-in wireless - a considerable convenience for modern workflows, allowing image transfer to phones or computers without cables. Sadly, the WS80 lacks any wireless features, which feels outdated in today’s connected world.

Physically, the SZ5 benefits from a slightly better grip and larger screen, improving handling. The WS80, constructed for waterproofing, is very rigid and sealed but feels less refined ergonomically.

Neither camera supports external flashes or accessories, limiting lighting options.

Battery types differ: the Pentax uses a D-LI68 battery, typical in rugged compacts, but battery life is modest. The Panasonic’s battery life is better, rated around 250 shots, verified in my field tests, making it more suitable for day trips without spares.

My Methodology and Testing Setup

For this review, I used both cameras simultaneously side-by-side in controlled and real-world settings: outdoor daylight landscapes, wildlife near slow rivers, indoor portrait sessions with continuous lighting, street photography walks, and casual videography.

I measured autofocus speed using a custom setup with stationary and moving targets under various light conditions and verified buffer depths via continuous shooting tests.

ISO noise was examined in a darkroom environment illuminated with constant low-level light, comparing noise levels and detail retention.

Ergonomics and interface usability were tested by running timed tasks to simulate quick setting changes during shooting sessions.

Because these cameras are nearly a decade old, I emphasize how they stand against one another rather than modern cameras.

Putting It All Together: Scores and Final Takeaways

Overall, the Panasonic Lumix SZ5 shines as a versatile compact camera aimed at casual photographers who want more zoom reach and better image stabilization without manual control complexities. Its slightly larger sensor resolution, longer zoom, and wireless connectivity bolster its value.

The Pentax Optio WS80 carves out its niche as a robust rugged waterproof compact for adventure-minded shooters willing to forgo zoom range and image stabilization in exchange for durability and weather resistance. Its manual focus and ruggedness are key selling points.

Who Should Buy Which?

• Choose Panasonic Lumix SZ5 if:

  • You want a solid travel compact with zoom power and stabilized images.
  • You shoot mostly daylight portraits, landscapes, or casual wildlife.

  • Your shooting environment is challenging and demands protection over performance.

Final Words: A Tale of Two Compacts

After extensive testing, I appreciate what each camera offers for its respective target user. The 2012 Panasonic Lumix SZ5 is a jack-of-many-trades - a lightweight, versatile point-and-shoot with longer zoom and competent image stabilization that best serves travel and casual portrait shooters.

The 2009 Pentax WS80 is more specialized, appealing directly to the rugged outdoor enthusiast who prioritizes durability and reliability in wet or dusty conditions over speed or zoom range. It will disappoint in fast-action shooting or low-light image quality but shines as a dependable field companion.

Both cameras have aged naturally with sensor tech advances since their release, but within their design scope, they perform credibly. Enthusiasts who require RAW capture, pro modes, or best image quality should look at modern mirrorless or DSLR cameras instead.

I hope this comparison offers you clear insights and saves time in your camera search.
