Panasonic LZ40 vs. Pentax WG-1 GPS: The Ultimate Hands-On Comparison for Enthusiasts and Pros

When two cameras from very different design philosophies land on your review desk, the result is always a compelling story about what “camera” means in various shooting contexts. Today, we're pitting the Panasonic Lumix DMC-LZ40 - a bridge-style superzoom from 2014 - against the rugged Pentax Optio WG-1 GPS, a compact waterproof warrior introduced three years earlier. Despite being in the same price bracket, they cater to decidedly different photography niches.

Having logged hours shooting with both models under natural light, low light, water splashes, and urban environments, I’ll walk you through their key characteristics, strengths, and compromises. We'll explore sensor qualities, autofocus, ergonomics, and genre-specific performance that matter most in the field.

Let’s dive in with a first-hand look at how these cameras stack up physically.

Size, Handling, and Ergonomics: Form Meets Function

Looking at these two side-by-side, the Panasonic LZ40 has a bulkier, SLR-like bridge camera shape, while the Pentax WG-1 GPS is a compact tough camera designed to accompany adventures where durability is critical.

At 126x87x94mm and 524g, the LZ40 is comparatively large and heavy for a fixed-lens camera. Its deep grip and SLR-styled body offer more secure handling, especially with the long telephoto reach. However, this size makes it slightly less pocketable, and you’ll definitely want a bag for longer shoots.

Contrast that with the Pentax WG-1 GPS at just 116x59x29mm and 167g - featherweight and easy to slide into jacket pockets or clips on a backpack. Its tough rubberized body feels sturdy - the “go-anywhere” vibe is unmistakable. The Pentax’s compact footprint suggests you won’t likely grab it for a serious still life shoot but rather for spontaneous moments, travel, or wet conditions.

The control layout on the Panasonic is more in line with traditional cameras, offering several tactile buttons and a multi-directional control dial, while Pentax keeps it minimal but intuitive, focusing on weatherproof reliability over fancy dials.

We’ll revisit controls more when discussing the user interface, but the initial takeaway: ergonomics tip towards the LZ40 for grip comfort and functionality; the WG-1 GPS wins for portability and toughness.

Design and Controls: Intuitive or Minimalist?

Moving on to the top-down perspective gives us insight into how the two cameras anticipate your needs during shoots.

The Panasonic LZ40’s DSLR-style design includes dedicated buttons for exposure compensation and manual modes, which is a bit unusual for this price range and sensor category. While manual exposure mode is limited, its inclusion means you can get creative beyond automatic modes - handy for challenging lighting.

The WG-1 GPS steers clear of such complexities. Its buttons are bigger and labeled clearly - great for underwater or dirty-gloved situations - but with no manual exposure control, it’s entirely an automatic experience. This may frustrate enthusiasts who want fine control but suits casual shooters or those prioritizing ruggedness and simple operation.

Neither camera has an electronic viewfinder, a compromise you expect in budget compacts or bridge cameras, and both rely entirely on their LCDs.

Speaking of which...

The Panasonic offers a larger 3-inch 460k-dot TFT LCD - bright and reasonably sharp. The fixed screen restricts angle creativity but is still adequate for composing in daylight.

In contrast, the Pentax’s smaller 2.7-inch 230k-dot LCD is more limited in resolution and not as bright, but its anti-reflective coating marginally improves outdoor visibility.

Neither touchscreen feature nor articulated screens are present, which feels dated but typical for cameras launched in their respective years.

Sensor and Image Quality: The Heart of Performance

Both cameras sit on a common foundation: a 1/2.3-inch CCD sensor, but Panasonic’s LZ40 boasts a 20MP resolution compared to 14MP for the Pentax. The sensor dimensions (6.17 x 4.55 mm) are identical, pointing to almost identical light-gathering surface area.

In field tests, the Panasonic typically yielded sharper images with more detail - expected from the higher pixel count - but both struggled similarly under low light due to inherent limitations of small sensors and CCD technology.

Noise levels in high ISO shots (above ISO 800) increased significantly, with Panasonic managing slightly better noise smoothing without obliterating fine details. Pentax’s maximum ISO of 6400 is somewhat theoretical since images get very soft and noisy even at lower ISO settings.

Neither camera provides RAW support, restricting post-processing flexibility - a serious limitation for enthusiast or professional photographers seeking full control over their images.

Dynamic range is narrow - highlights tend to clip fast in bright outdoor scenes, and shadows lose detail quickly, which impacts landscape photography requiring subtle tonal gradations.

Lens and Zoom Capabilities: From Wide to Super Tele

Zoom range is often the decisive factor in bridge and compact cameras. Panasonic’s 42x zoom is eye-catching on paper:

• Panasonic LZ40: 22-924mm equivalent (42x optical zoom)
• Pentax WG-1 GPS: 28-140mm equivalent (5x optical zoom)

The LZ40 thus covers everything from moderate wide-angle snapshots to extreme telephoto wildlife or sports.

The Pentax’s more modest zoom is typical in waterproof compacts where optical complexity is minimized for ruggedness.

Both lenses have relatively slow maximum apertures (f/3.0-6.5 on Panasonic, f/3.5-5.5 on Pentax), limiting low-light performance and bokeh potential.

In practice, the Panasonic lens resolves sharper at wider focal lengths and maintains contrast better throughout its zoom range, though image stabilization is vital given the telephoto reach.

Speaking of stabilization, the Panasonic incorporates optical image stabilization, which proved helpful during handheld telephoto shots, considerably reducing blur.

The Pentax WG-1 GPS lacks any form of image stabilization. This absence is noticeable, especially at the long end of its zoom, where shaky hands quickly degrade image sharpness.

Autofocus and Shooting Performance: Speed, Accuracy, and Tracking

Despite their consumer-level heritage, autofocus systems differ significantly in usability and sophistication.

The Panasonic LZ40 uses a contrast detection AF with 9 focus points, including face detection and tracking. While no phase detection is present, Single AF and Continuous AF modes are usable in practice.

The Pentax WG-1 GPS also employs contrast-detection AF and offers 9 focus points but lacks face or eye detection. Autofocus speed is noticeably slower on Pentax and can hunt quite a bit under dim lighting or during zoom changes.

Neither camera excels at burst shooting - both offer just 1 fps continuous shooting speed, which is astonishingly slow by modern standards, thus limiting their utility for action or wildlife bursts.

Real-world experience confirms both cameras work well for static subjects and casual shooting but can frustrate users aiming to track moving subjects effectively.

Specialized Photography Use-Cases: How Do They Hold Up?

Let’s break down their performance across popular photography genres.

Portrait Photography

• Panasonic LZ40: Benefiting from higher resolution and face detection autofocus, skin tones render with reasonable naturalness under daylight. However, the small sensor limits shallow depth-of-field effects, making background separation challenging. The optical zoom makes framing portraits easy at telephoto range, but aperture limits prevent creamy bokeh.

• Pentax WG-1 GPS: Lower resolution and no face detection autofocus reduce precision for portraits. Shallow depth of field is practically nonexistent at the compact sensor size and aperture. Still, it can capture pleasing candid portraits in bright conditions.

Landscape Photography

Here, dynamic range and resolution are key.

• Panasonic’s 20MP sensor edges out Pentax in detail, allowing larger prints or cropping. However, the lack of RAW and narrow dynamic range limit post-processing options for recovering shadows or highlights.

• Pentax’s 14MP resolution may suffice for social sharing but lacks fine detail retirement. Weather sealing and ruggedness make the WG-1 GPS more suitable for tough landscape adventures exposing the camera to elements, which could damage the LZ40.

Wildlife Photography

Telephoto reach is critical.

• Panasonic’s whopping 924mm equivalent puts it miles ahead for distant wildlife shots, though AF speed and 1 fps continuous shooting hinder capturing fast action.

• Pentax’s 140mm equivalent zoom falls short for serious wildlife, designed more for close nature shoots or underwater critters.

Optical stabilization on Panasonic aids handheld wildlife photography, whereas the Pentax benefits from ruggedness but less zoom and no stabilization limit results.

Sports Photography

Both cameras struggle.

The 1 fps burst and contrast-detect AF systems do not meet fast sports tracking needs. Athletic action requires rapid frame rates and phase detection or hybrid AF, which neither camera offers.

Street Photography

Street shooters value compactness, discretion, and quick AF.

The Pentax WG-1 GPS is better suited here because of its smaller, lightweight body and less conspicuous design. Its waterproofness adds an adventurous edge.

The Panasonic feels bulky for street work and has a longer zoom that might draw attention.

Macro Photography

Both cameras surprisingly perform decently at close focus:

• Macro focus range is about 1 cm on both, allowing tight framing.

• Panasonic’s optical stabilization and manual exposure allow for some experimentation.

• Pentax offers no stabilization and fewer control options but can shoot underwater macros - a unique strength.

Night and Astro Photography

Neither camera excels in low light:

• Both max out ISO sensitivity at 1600 (Panasonic) or 6400 (Pentax), but noise is heavy above ISO 800.

• Lack of RAW makes night sky editing nearly impossible.

• Minimum shutter speeds of 15s (Panasonic) and 4s (Pentax) vary; without manual exposure controls (Pentax), astro shots remain challenging.

Video Capabilities: Modest but Serviceable

Both cameras shoot 720p HD video:

• Panasonic: 1280x720 @ 30fps, microphone port included (a plus!)

• Pentax: 1280x720 @ 30 or 15fps, no mic input.

Neither provides stabilization in video mode beyond Panasonic’s optical.

Recording format is Motion JPEG - older and storage-heavy.

No 4K, no advanced video features, but both suffice for occasional home videos and casual use.

Battery Life and Storage Options: Ready for the Day

Panasonic offers 320 shots per charge; Pentax offers 260 shots - reasonable but not exceptional.

Both use proprietary battery packs and SD/SDHC/SDXC cards.

Connectivity is sparse:

• Panasonic lacks wireless features.

• Pentax supports Eye-Fi wireless card connectivity and GPS tagging - which is a standout feature for geotagged travel photography.

Durability and Environmental Resistance: A Clear Winner

If you demand weather, shock, dust, freeze, and crush resistance, the Pentax WG-1 GPS is unmatched here:

• Waterproof down to certain depths (exact spec varies by model)

• Shockproof design encourages outdoor ruggedness

• Dust and freeze-proof rating mean it thrives where other cameras would clunk shut.

The Panasonic LZ40 is strictly indoor/dry conditions and should be handled carefully.

Pricing and Value Analysis

At launch, Panasonic LZ40 priced around $219, while Pentax WG-1 GPS commanded about $350 due to its rugged, waterproof design and GPS.

So what do you get for the premium?

• Durability and specialized tough environments (Pentax)

• Larger zoom reach, better sensor resolution, and stabilization (Panasonic)

Neither offers modern features expected in 2024 but each has niche value depending on your preferred shooting conditions.
