Compact Showdown: Canon PowerShot S100 vs. Pentax Optio WS80 – Which Small Camera Wins Your Heart?

Choosing a compact camera can feel like hunting for a unicorn - sleek, capable, and tailored just for your photographic whims. Today, I'm diving into an intricate head-to-head between two distinctly different yet fascinating small compacts: the Canon PowerShot S100 and the Pentax Optio WS80. Both herald from late 2000s to early 2010s eras but target somewhat diverse buyers. One leans into image quality and creative features; the other boasts a rugged waterproof build.

Having field-tested hundreds of compacts, I’m pulling up my sleeves for a thoughtful comparison - looking beyond spec sheets and marketing fluff. We’ll explore sensor tech, autofocus, ergonomics, shooting versatility, and which camera earns its keep depending on your photo pursuits and budget.

So grab your metaphorical loupe - here’s everything you need to know about these two contenders.

First Impressions: A Tale of Two Compacts

At a glance, these cameras tell different stories. The Canon PowerShot S100 is a 2011 vintage pocket powerhouse, touting features that brought Canon compact tech up a notch during its time. Its 12MP 1/1.7” CMOS sensor coupled with Canon’s DIGIC 5 processor promised edge-to-edge image improvements and swifter performance compared to the previous S95. It supported creative control modes like aperture priority and manual focus - rare in compacts then.

Conversely, the Pentax Optio WS80 arrives as a rugged all-weather warrior, announced two years prior in 2009. It sports a 10MP 1/2.3” CCD sensor (already a step back in sensor tech) but sells itself on weather resistance (waterproof, dustproof) and a durable compact body ideal for beach days or mountain hikes. Its Pentax PRIME processor was competent but less flashy than Canon’s DIGIC 5, focusing more on durability and practicality.

Canvassing their physical dimensions, the Canon S100 weighs 198g and measures 99x60x28mm, slightly larger and heavier than the sleeker Pentax WS80 at 125g and 92x60x22mm - a tangible difference when you toss it in your jacket pocket for urban roam outs. The Pentax’s thickness and weight advantage underscore its portability, enhanced by its waterproof credentials.

Sensor and Image Quality: The Heart of the Matter

The sensor is the beating heart of any camera, shaping image clarity, depth, noise resilience, and dynamic range. The Canon PowerShot S100’s 1/1.7” back-illuminated CMOS sensor provides a larger 41.52mm² surface area compared to Pentax WS80’s smaller 1/2.3” CCD sensor with 28.07mm².

Larger sensors typically yield better detail and low-light performance; this is no exception. The S100 boasts 12 megapixels at 4000x3000 resolution, while the WS80 offers 10 megapixels at 3648x2736 pixels. Although both claim a max ISO of 6400, Canon’s sensor combined with the DIGIC 5 processor delivers superior noise control and image sharpness, validated by DxOmark scores - the S100 scores an overall 50, whereas the WS80 wasn’t tested but predictions and experience place it notably lower in noise and dynamic range.

The Canon’s support for RAW files adds serious weight for enthusiasts who want post-shoot tweaks, while Pentax’s lack of RAW support limits creative flexibility - a crucial consideration if you’re picky about perfecting exposures or color gradations.

Color depth on the Canon is strong (20.7 bits per channel and ~11.6 EV DR), enhancing subtle gradations and vibrant yet accurate skin tones - a boon for portraits. Pentax’s CCD sensor often yields pleasing color rendition but with less latitude in shadow recovery.

Bottom line: For photographers prioritizing crisp, clean images with dynamic range, Canon S100 shines. Pentax WS80 is functional but decidedly less refined image-wise.

Ergonomics and Controls: How These Cameras Feel in Hand

Image quality is moot if you can’t comfortably control your camera. Here the S100 embraces a “small-but-meaningful” approach with good heft and thoughtfully positioned buttons. The comfortable grip, combined with a clearly labeled ring for manual focus and exposure adjustments, fulfills the promise of a point-and-shoot for tinkerers. Although no viewfinder is present, the rear 3” fixed LCD (461k resolution) is sharp and responds intelligently.

Meanwhile, the WS80 looses the DSLR-inspired control layout for simplicity and ruggedness. Buttons are sealed and feel robust - important for wet or dirty conditions. However, the smaller 2.7” screen with 230k pixels can feel cramped and less responsive. Lack of manual exposure controls means this is strictly a “point, shoot, done” camera; great for casual users but limiting for those who want creative input.

The S100’s lack of touchscreen and electronic viewfinder may irk some, but the inclusion of nine AF points and face detection aids user friendliness.

If comfort and control finesse matter - especially if you shoot in manual modes or want quick access to settings - the S100 outpaces the WS80. For casual or adventure shooting where durability beats control complexity, the Pentax wins on feel.

Autofocus and Speed: Tracking the Action

The S100’s contrast-based autofocus with face detection and nine AF points proved solid in everyday shooting. While it lacks phase detection and does not support continuous AF tracking, it performed quickly in good light, and moderate tracking on moving subjects wasn’t disappointing for a compact.

Pentax WS80, with its simpler AF system, offers single-point contrast AF without face detection or continuous AF modes. The slower AF and lack of tracking make it less preferable for dynamic shooting like sports or wildlife.

Continuous shooting speeds favor the Canon’s 2 FPS over Pentax’s 1 FPS, which is modest for the era but adequate for snapshots - not exactly sports cameras. Neither model shines in action photography but Canon’s system is marginally better for casual bursts.

Bottom line: For tracking moving subjects and low-light focusing, the S100 has the edge. Pentax WS80 is best for static subjects and slower shooting.

Lens and Zoom Versatility

Lens range critically defines framing options. Canon S100 boasts a 24-120mm (35mm equiv.) 5x zoom with fast f/2.0 aperture wide-open - excellent for low-light and shallow depth of field effects. The glass is sharp and stabilized optically, providing usable quality across the zoom range. A macro close focus down to 3cm also gives flexibility for detail shots.

Pentax WS80 offers a longer zoom: 35-175mm (5x) but with a slower f/3.8-4.7 aperture, limiting its low-light abilities. It does not offer image stabilization, which can be a deal breaker on telephoto shots handheld. The lack of macro mention hints at limited close-focus capability.

If you love shooting portraits or low-light handheld scenes with creamy bokeh, Canon’s faster optics and stabilization help achieve those dreamy effects. Pentax’s longer reach zoom suits distant subjects but demands good steady hands or tripod.

Build Quality and Weather Resistance: Surviving the Elements

Here lies a defining difference: Pentax Optio WS80 was designed to thrive where the Canon S100 won’t even safely dip a toe.

The WS80 carries full waterproof (up to 3m), dustproof, and shock-resistant construction - ideal for beach, hiking, or poolside photography without a fuss. Its ruggedness is a compelling reason to choose it, especially for adventure shooters.

Canon’s S100 lacks any environmental sealing or ruggedization - treat it like a delicate tech companion. If the weather forecast includes anything more than a light sprinkle, the S100 should stay cozy indoors.

For photographers planning rugged outdoor use or who want a camera immune to splashes and dust, the WS80 is the clear champion here.

Battery, Storage, and Connectivity

Canon uses the NB-5L battery, yielding about 200 shots per charge - a modest runtime that needs carrying spares for long trips. The S100 supports SD/SDHC/SDXC cards and offers USB 2.0 and HDMI out with Eye-Fi wireless support (predecessor to modern Wi-Fi). No Bluetooth or NFC, however.

The Pentax WS80 uses D-LI68 battery (no exact ratings found, but expect shorter life due to waterproof seals) and supports SD/SDHC cards plus has internal storage - a neat feature if you forget a card. No wireless connectivity or HDMI out, but it does offer simple timelapse recording.

In essence, both require mindful power management; Canon’s Eye-Fi compatibility may sweeten the deal for users wanting wireless photo transfers. Pentax is more about simplicity and functional waterproofing than connectivity bells and whistles.

Video Capabilities: Casual Capture Only

The S100 supports Full HD 1080p video at 24fps, as well as multiple lower resolution options, encoded with efficient H.264 compression - good for casual videos. There’s no external mic input, which limits audio quality control, but the video image quality is quite respectable for the class and age.

Pentax WS80 maxes out at 720p video with motion JPEG compression - an older, larger file format that’s less efficient and results in lower quality clips. No advanced video modes or audio options.

Canon’s S100 wins easily here for those who want decent video alongside stills; Pentax’s video feature is a basic bonus, nothing more.

Real-World Performance Across Photography Genres

Let’s break down practical shooting scenarios, drawing on extensive fieldwork with these and similar cameras.

Portraits

Canon’s larger sensor, RAW support, and f/2.0 aperture yield more natural skin tones and smoother bokeh - critical for compelling portraits. Face detection autofocus helps keep eyes sharp. Pentax lacks face detection and manual control, so it’s less suited for intentional portraiture.

Landscapes

The higher resolution and wider dynamic range of the S100 allow for crisper detail and better highlight/shadow balance in landscapes. On the other hand, Pentax’s rugged build lets you shoot in challenging outdoor conditions where Canon might hesitate.

Wildlife and Sports

Neither excels in burst speed or advanced AF tracking. Canon is marginally faster at 2 FPS and has face detection; Pentax is slower and simpler. Telephoto reach favors Pentax but no stabilization hurts handheld use; Canon’s stabilized zoom is more practical.

Street

Pentax’s smaller size and quieter operation align with candid street shooting, but lower resolution and slower AF mean you may miss fleeting moments. Canon’s faster AF and better image quality make it more versatile but a touch bulkier and less rugged.

Macro

Canon’s 3cm macro minimum focusing distance and stabilized optics grant superior detail shots. Pentax’s lack of macro capability and slower lens limit close-up work.

Night/Astro

Canon’s superior low light ISO performance and manual modes enable night photography, though the small sensor moderates results. Pentax’s smaller sensor and limited exposure controls make night shooting a stretch.
