Panasonic Lumix DMC-TS20 vs. Pentax Optio WG-2: A Hands-On Comparison of Two Rugged Waterproof Compacts

When it comes to rugged, waterproof point-and-shoot cameras, enthusiasts and professionals alike often face a perplexing trade-off between durability, image quality, and versatility. I’ve spent years testing and carrying various tough compacts in every environment - from tropical beaches and freezing mountain peaks to bustling urban streets - to see which models genuinely deliver beyond their rugged exteriors.

In this deep-dive comparison, I pair two waterproof compacts launched within a week of each other in early 2012: the Panasonic Lumix DMC-TS20 (aka Lumix DMC-FT20) and the Pentax Optio WG-2. Both cameras boast weather sealing, shockproof construction, and fully fixed lenses, but they differ in sensor design, feature set, controls, and real-world usability.

Drawing from extensive hands-on tests, lab measurements, and field trials across multiple photographic disciplines, I will analyze each camera’s technical prowess, practical performance, and value proposition. Whether your focus is landscape, wildlife, travel, or casual adventure snaps, this comparison will help clarify which rugged compact is best suited to your needs.

Comparing Physical Dimensions and Ergonomics: Compactness vs. Control

First impressions matter, especially outdoors. Both cameras fit comfortably in a jacket pocket or backpack but emphasize different design philosophies.

The Panasonic TS20 slices a slim profile at 101x58x19mm and weighs a mere 142g, making it extremely pocketable. Its body feels smooth and subtly contoured but lacks pronounced grips, which sometimes makes handling slippery or awkward when wet or gloved. The buttons are compactly arranged with limited tactile differentiation, requiring a bit of 'hunt and peck' in low-light or fast-paced scenarios.

The Pentax WG-2, by contrast, is chunkier at 122x61x30mm and about 50% heavier (192g). This bulkier footprint prioritizes ruggedness and grip security. The WG-2 features a molded rubberized grip and spaced, sizeable control buttons with some illumination - critical improvements when operating with wet hands or outside in dim conditions. The build exudes confidence and withstands harsher environments (including crushproof claims that Panasonic lacks).

In summary, if pocketability and minimal weight are your priorities for travel or casual street use, the TS20 earns points. Should you require a more tactile and rugged experience for adventure shooting, WG-2’s ergonomic advantages justify its heft.

Top Controls and Interface: User Experience Underwater and On the Trail

The top control layout defines how quickly one can adjust exposure modes, zoom, and shooting options under challenging conditions.

Panasonic’s TS20 has a fairly minimalist top plate without dedicated zoom controls. It relies on rear toggles and on-screen menus, which can slow responsiveness but reduce accidental triggers. The single shutter button feels crisp but slightly shallow.

Conversely, the Pentax WG-2 features dedicated zoom rocker switches with a textured finish for intuitive thumb operation - ideal for underwater dives or rugged terrain photo ops where quick focal length changes are crucial. The power and shutter buttons are logically spaced, reducing command errors during rapid shooting moments.

Neither camera offers physical dials for aperture or shutter priority, reflecting their entry-level positioning. But WG-2 being slightly more manual control friendly (including actual manual focus capability) is a noteworthy bonus for users who want some creative authority.

Under the Hood: Sensor Technology and Imaging Performance

Here is where the cameras fundamentally diverge - sensor architecture and consequent image quality consequences alone can sway a serious buyer.

• Panasonic TS20 captures images on a 16MP 1/2.3" CCD sensor. While CCDs historically emphasize lower noise and better color rendition, this sensor is more dated in 2012 standards and less forgiving at higher ISOs. The maximum native ISO is 6400, with a real-world practical ceiling around 800 before noise becomes intrusive.

• Pentax WG-2, meanwhile, employs a 16MP BSI-CMOS sensor of the same size. BSI (Back-Side Illuminated) CMOS sensors offer enhanced light gathering efficiency and improved high-ISO performance. This translates to relatively cleaner images in dimmer settings and better dynamic range.

In my testing, landscape scenes displayed crisper detail in WG-2’s files, with marginally better color depth and dynamic handling of shadows and highlights. The Panasonic struggled more in complex lighting (sunrises/dusk), tending to clip highlights or produce denser noise in shadows.

Although both include an anti-aliasing filter to suppress moiré, the WG-2’s newer sensor tech yields clearer texture and finer detail preservation. For enthusiasts who plan to heavily crop or print large, WG-2 is the smarter choice.

Rear LCD and Viewfinder: Monitoring Shots in the Field

Neither is equipped with a dedicated viewfinder, but the rear screen is an indispensable tool, especially with waterproof bodies.

Panasonic’s TS20 offers a 2.7-inch, 230k-dot TFT LCD - functional but dim and with limited viewing angles. In bright sunlight or underwater, the display can become nearly illegible. This can complicate composition and reviewing images, especially when wearing polarized sunglasses.

Pentax WG-2 ups the ante with a 3-inch, 460k-dot widescreen TFT LCD featuring an anti-reflective coating. The benefit is immediately noticeable: sharper detail, richer colors, and improved visibility outdoors or underwater. I found this screen superb for framing intricate macro shots or critiquing wildlife photos on the spot.

In sum, the WG-2’s screen significantly boosts the shooting experience, while TS20’s LCD feels somewhat basic by comparison.

Lens and Focusing: Versatility and Precision in Rugged Settings

Lens specs and autofocus ability form the backbone of any camera’s shooting versatility.

• Panasonic TS20 sports a 25–100mm equivalent zoom with a 4x range, aperture from F3.9–5.7, and minimum macro focus distance of 5cm.
• Pentax WG-2 offers a 28–140mm equivalent, 5x optical zoom, with a slightly faster max aperture range of F3.5–5.5 and an impressively close 1cm macro focus distance.

The WG-2 provides more focal length versatility, which is especially useful for wildlife and sports where reach matters, without sacrificing wide-angle utility crucial for landscapes and travel.

Autofocus systems differ notably:

• TS20 utilizes contrast detection with 23 focus points, supporting continuous autofocus and tracking but lacking face or eye detection.
• WG-2 includes 9 focus points and implements face detection, which assists portrait and street shooters. However, it lacks continuous AF, which limits burst accuracy for fast action.

During wildlife and macro testing, WG-2’s close macro range and reliable AF lock consistently outperformed Panasonic’s more generalist system. However, TS20’s continuous focus capability is preferable for moving subjects when tracking is key, despite less sophisticated spotting.

Shooting Performance: Speed, Burst, and Stability Matters

Fast operations matter in sports, wildlife, and spontaneous moments.

• Burst rate on both cameras peaks at approximately 1 FPS, indicating neither is designed for rapid continuous shooting. This restricts their suitability for high-speed sports photography.
• Panasonic’s optical image stabilization offers a practical advantage in low light, effectively reducing blur from hand shake during telephoto or macro work.
• Pentax notably lacks stabilization, which can be a dealbreaker in certain low-light or telephoto scenarios.

Shutter speed ranges:

• TS20 fares from 8s to 1/1300s
• WG-2 stretches shutter speeds from 4s to 1/4000s

Pentax’s broader shutter speed coverage gives added creative freedom in bright light or when attempting motion freeze shots.

Weather Sealing and Durability: Built for Extreme Environments

Both cameras shine in environmental resistance, crucial for adventurous photographers.

• Panasonic TS20 is waterproof, dustproof, shockproof, and freezeproof (down to a certain temperature), but lacks crushproof rating.
• Pentax WG-2 ups the ante with waterproof to deeper depths, dustproof, shockproof, freezeproof, and crushproof claims.

The WG-2’s reinforced construction translates to confidence when shooting in rugged terrain or extreme climate zones. It survives drops, pressure, and cold better than most compacts I've tested, including the TS20.

For expeditions or demanding adventures, WG-2’s superior build earns a definite edge.

Size, Weight, and Travel Photography: Real-World Portability

While I already noted TS20's slimness and lightness, its compactness significantly aids in minimalist travel and street photography packs where every gram counts. Its smaller lens extends less from the body, making it less obtrusive.

The WG-2, while obviously bulkier, still fits easily in backpack straps or jacket pockets designed for thicker gadgets. Its extra heft is a reasonable tradeoff for its enhanced durability and control ergonomics.

Battery life is comparable: Panasonic rated at about 250 shots per charge vs. 260 for Pentax, sufficient for casual day trips but necessitating spares for extended outings.

Image Quality in Practice: Evaluating Sample Shots

Examining real-world JPG outputs reveals telling differences:

• Panasonic TS20 images feature bright, pleasant colors with slight warmth - particularly flattering on skin tones in portraits. However, under lower light, softness and noise creep in.

• Pentax WG-2’s images are sharper with more accurate color rendition, especially in complex light and shadow areas. Macro images displayed excellent detail down to the millimeter, thanks to its 1cm minimum focus.

Dynamic range favors WG-2 as well. On landscape shots, WG-2 maintained better highlight retention (cloud details) and preserved shadow texture more consistently.

Video Recording Capabilities: Documentation Beyond Still Photos

Video is secondary in these models but worth noting:

• Panasonic TS20 shoots 1280x720 (HD) at 30fps.
• Pentax WG-2 records in Full HD 1920x1080 at 30fps, plus 720p at 60fps for slow-motion effects.

Both lack microphone or headphone ports, limiting professional use, but WG-2’s sharper, higher-res footage is more versatile for casual video capture. Neither offer in-body stabilization in video mode, so shooting steady hand-held requires care.

Connectivity and Storage: How Do They Link and Save?

Both cameras accept SD/SDHC/SDXC cards with a single slot. Panasonic additionally supports internal storage.

Connectivity is sparse:

• Panasonic TS20 offers only USB 2.0, without wireless or HDMI.
• Pentax WG-2 stands out with HDMI output and Eye-Fi compatibility for wireless image transfer.

While wireless features were nascent in 2012, WG-2’s Eye-Fi control ability screams ahead in convenience for quick sharing - an advantage for casual shooters wanting to offload shots on the go.

Price and Value: Stretching Your Dollar

Pricing at launch differed considerably:

• Panasonic TS20 retailed around $179.
• Pentax WG-2 commanded roughly $350.

This near doubling in price reflects WG-2’s more advanced sensor, improved ergonomics, build toughness, screen quality, and video specs. For budget-minded users prioritizing waterproof protection and basic photography, TS20 offers an entry point.

However, when value is measured by capability and image quality per dollar, WG-2 arguably delivers stronger overall performance and versatility, justifying the premium for enthusiasts willing to invest.
