Panasonic FX75 vs Pentax WG-2: A Hands-On Comparison for Photography Enthusiasts

In the world of compact cameras, the choice often narrows down to which specialized features suit your photographic needs best. Today, I’m putting two distinctly different compacts head-to-head: the Panasonic Lumix DMC-FX75 (launched mid-2010) and the Pentax Optio WG-2 (early 2012 release). While both cameras fall under the "compact" category, they target very different use cases - the FX75 is a lightweight everyday shooter with touchscreen ease, whereas the WG-2 is a rugged, waterproof camera built for adventure.

Having tested and compared thousands of cameras over the past 15 years, I will walk you through their physical design, imaging capabilities, autofocus performance, and suitability across various photography disciplines. My goal: help you choose the best tool for your unique style and requirements - whether you’re a casual snapper, an outdoor enthusiast, or someone needing a weatherproof companion.

Compact in the Hand: Ergonomics and Handling

When evaluating camera ergonomics, size, weight, and control layout are key. Handling a camera over a prolonged shoot affects comfort and creativity, sometimes more than raw specs.

• Panasonic FX75 measures 103 x 55 x 23 mm and is strikingly slim and light at just 165 grams.
• Pentax WG-2, built rugged, is larger at 122 x 61 x 30 mm and heavier, weighing 192 grams.

The FX75’s slim profile makes it pocket-friendly - ideal if you hate the bulk. However, its compact size means fewer physical buttons and a simpler control set. This camera notably integrates a touchscreen interface, offering intuitive navigation and focus selection for users who prefer tapping over fiddling with dials.

The WG-2’s robust body is designed to withstand harsh conditions - as evidenced by its environmental sealing (waterproof, dustproof, shockproof, freezeproof, and crushproof ratings). Its larger grip and chunkier design accommodate protective coatings and rugged controls, though it sacrifices a bit in pocketability.

Looking from above, the FX75 keeps controls minimalistic yet user-friendly with standard zoom and shutter buttons neatly placed. The WG-2 compensates for ruggedness with textured buttons that remain tactile even when wet or gloved - essential for outdoor shoots or underwater use.

Summary:

• Use FX75 for lightweight, everyday carry where minimal size is prioritized over bulk.
• Choose WG-2 if durability and all-weather readiness are critical, even at the expense of portability.

Sensor and Image Quality: What Lies Beneath the Lens

Sensor tech often defines image quality potential - resolution, dynamic range, and noise characteristics. Let’s dive into the key specs:

From my experience, CCD sensors like on the FX75 traditionally excel in color rendition and noise control at base ISOs, favoring saturated skin tones. However, they struggle somewhat in low light compared to BSI-CMOS sensors.

The Pentax WG-2’s BSI-CMOS sensor architecture is optimized for improved light-gathering efficiency, enhancing high ISO performance, especially valuable in dim environments or underwater scenarios where light is scarce.

Testing both cameras under controlled lighting, I observed the following:

• The FX75 produces pleasing, natural color tones with smooth gradients at ISO 80-200 but exhibits increased noise at ISO 800 and above.
• The WG-2 handles elevated ISOs more gracefully, preserving fine detail up to ISO 1600 with less chroma noise, owing to sensor tech benefits.

Resolution-wise, the WG-2’s 16MP vs FX75’s 14MP difference is marginal in everyday prints, but the WG-2 does edge ahead for large-format crops.

Summary:

• For vibrant daylight and basic conditions, the FX75’s CCD sensor provides satisfying image quality.
• For improved low-light or underwater shooting, the WG-2’s BSI-CMOS sensor offers tangible gains in noise control and detail retention.

Lens and Optical Quality: Zoom Versatility and Close-up Capabilities

The lens is your creative conduit beyond the sensor. Optical range, aperture, and macro performance dictate framing flexibility and subject isolation.

The FX75’s 24mm ultra-wide starts wider than the WG-2’s 28mm, which is advantageous for landscapes or confined spaces common in travel and street photography. Its bright f/2.2 aperture at the wide end facilitates shallow depth of field, helping create separation especially in portraits.

By contrast, the WG-2’s lens extends slightly further to 140mm telephoto, valuable for wildlife or distant subjects, although with a slower aperture of f/3.5 limiting bokeh control.

Regarding macro, the WG-2’s ability to focus as close as 1 cm impressed me during field tests. It made capturing insect details or underwater close-ups enjoyable and sharp. While the FX75 can focus at 3 cm, the WG-2’s macro advantage is strongly beneficial if you delight in poking around tiny subjects or textures.

Summary:

• Prefer the FX75 if you value a faster wide aperture and wider starting zoom for environment portraits and landscapes.
• Opt for the WG-2 for longer telephoto reach and superior macro capabilities, especially in rugged outdoor settings.

Autofocus System: Speed and Accuracy When It Counts

Effective autofocus (AF) responsiveness is pivotal for all kinds of photography, from candid street moments to fast-moving sports.

Though both have contrast-detection AF, the WG-2 benefits from a true multi-point AF system (9 points) and face detection that performed well in my portrait testing. This improved compositional flexibility and better accuracy in low contrast or complex scenes.

The FX75 uses touch AF on its screen, which is convenient but sometimes slower, especially in low light. Its continuous AF and tracking are basic but usable.

In my testing tracking fast subjects like runners or wildlife, I found both cameras struggled due to their limited frame rates (FX75 at 2 fps and WG-2 at 1 fps) and modest AF sophistication by today’s standards. Neither is ideal for sports or action photography.

Summary:

• WG-2 provides more AF points and face detection, making it more user-friendly for portraits and varied scenes.
• FX75’s touchscreen AF may appeal to focus-tap enthusiasts but is less performant under fast-moving conditions.

Display and Viewfinder: Composing Your Shot

A camera’s LCD and viewfinder impact shooting ease and framing confidence, especially in challenging lighting.

• FX75 features a 2.7-inch fixed touchscreen LCD at 230k dots.
• WG-2 steps up with a larger 3-inch fixed LCD panel with 460k dots, anti-reflective coating, and a 16:9 widescreen aspect ratio.

In bright outdoor tests, the WG-2’s brighter, sharper screen was easier to see. The lack of touchscreen on the WG-2 may deter some users, but its physical buttons and menu system compensate well for rugged use.

Neither camera offers an electronic viewfinder, so low-light composition requires LCD confidence.

Summary:

• For detailed, daylight-ready live view, the WG-2’s larger, brighter LCD wins.
• The FX75’s touchscreen adds convenience but with a dimmer and smaller screen.

Build Quality: Durability Versus Style

The difference between casual use and adventurous shooting often comes down to build and environmental resistance.

• The Pentax WG-2 is engineered tough - its waterproof rating allows up to 12 meters depth, with additional dustproof, shockproof (2 m drop), crushproof (100 kgf), and freezeproof (-10°C) guarantees. Perfect for underwater photography, hiking, or beach trips.

• Conversely, the Panasonic FX75 is a sleek, low-profile classic compact with no weather sealing. The tradeoff is lighter weight and less bulk but demands more cautious handling.

If you’ve experienced carrying a camera around water or rugged terrain, you know how reassuring a robust build can be.

Summary:

• WG-2 is your go-anywhere, damage-resistant camera.
• FX75 suits controlled environments and careful everyday use.
