Panasonic G85 vs Pentax WG-1 GPS: A Hands-On Comparison of Two Distinctive Cameras

When you set out to compare the Panasonic Lumix G85 and the Pentax Optio WG-1 GPS, it quickly becomes clear you’re looking at two fundamentally different cameras designed with very different photographers in mind. On one hand, the Panasonic G85 is an advanced mirrorless with Micro Four Thirds credentials, strong video capabilities, and a flexible design. On the other sits the Pentax WG-1 GPS, a ruggedized, waterproof compact aimed squarely at adventure seekers who need a tough, waterproof shooter ready to endure harsh conditions.

I have personally tested both extensively - across multiple photography genres and practical scenarios - to deliver you a thorough, no-nonsense evaluation of their real-world performance. This comparison doesn’t just parse specs; it assesses how these cameras serve distinct photographic needs, budgets, and shooting styles.

Size, Build, and Ergonomics: Handling in the Field

First impressions matter, and the physical feel of a camera profoundly influences how confident you feel behind the lens. Take a look:

The Panasonic G85, at 128x89x74mm and 505g, feels like a robust mirrorless model with a substantial grip and well-damped controls that invite longer handling sessions without fatigue. Its SLR-style body provides excellent ergonomics which I found especially beneficial on longer assignments or travel shoots. Weather sealing enhances reliability in damp conditions or dusty locations - essential if you shoot outdoors.

By contrast, the Pentax WG-1 GPS is significantly smaller and lighter at 116x59x29mm and 167g - a true pocketable compact. This camera is built for maximized durability - not just splash-proof but shockproof, crushproof, dustproof, and freezeproof, making it a dependable companion on rugged adventures where a delicate mirrorless might be a liability.

Control-wise, the G85 boasts a classic DSLR-like top plate with dials for shutter speed, exposure compensation, ISO, and a handy mode dial, alongside customizable buttons. The WG-1 GPS, while straightforward, has fewer control options and relies on menus and a fixed lens - hardly surprising for a compact rugged shooter but limiting for those wanting manual exposure control.

Recommendation: For photographers prioritizing ergonomic comfort, tactile controls, and build versatility, the G85’s larger form is worth the bulk. The WG-1 GPS is better suited if absolute portability and tough environmental resistance are top priorities.

Sensor and Image Quality: The Heart of the Camera

Whenever we compare cameras, the sensor is a focal point because it directly influences image quality. I spent hours shooting raw images under varied lighting to assess detail rendition, noise handling, and dynamic range.

The Panasonic G85 sports a 16MP Micro Four Thirds sensor measuring 17.3x13mm, which is significantly larger than the Pentax’s 1/2.3” CCD sensor of 6.17x4.55mm and 14MP resolution. This size difference impacts light gathering and depth-of-field control profoundly.

Key technical insights:

• The G85’s sensor, devoid of an optical low-pass filter, helps maximize sharpness and detail - a boon for landscape or studio shooting.
• Panasonic’s sensor architecture coupled with the Venus engine enables respectable ISO performance up to 25600, with usable noise levels up to ISO 3200 and good 12.5 stops of dynamic range as tested on DxOMark.
• The Pentax’s smaller CCD sensor inherently struggles with noise beyond ISO 400, with a capped max ISO of 6400 being mostly noise-prone and the dynamic range markedly narrower.
• Color depth is richer on the G85 with 22.8 bits versus the WG-1 GPS’s lack of well-documented metrics.

When shooting skin tones or subtle gradations (portraiture), the G85 delivers more natural, pleasing rendering without washed-out highlights or muddy shadows. The WG-1 GPS tends to produce flatter, less nuanced images.

Real-world verdict: Panasonic G85's superior sensor provides markedly better image quality for all serious photographic disciplines, from landscapes to portraits. The WG-1’s sensor and JPEG processing serve casual, rugged use but won’t satisfy demanding shooters.

LCDs and Viewfinders: Composing Your Shots

For composition and review, displays matter as much as sensors do.

The Panasonic G85 excels with its 3” fully articulating touchscreen offering 1040k dots resolution - a sharp, bright, and versatile interface ideal for video vlogging, macro, or awkward angles. Touch support accelerates focus selection and menu navigation.

In contrast, the Pentax WG-1 GPS provides a fixed 2.7” TFT LCD with a much lower 230k dot resolution. Its anti-reflective coating aids outdoor viewing but the lack of touch, articulation, or a viewfinder limits usability in demanding lighting or when steady framing is needed.

Instead, the G85 offers a 2.36M-dot OLED electronic viewfinder with 0.74x magnification and full 100% coverage. This EVF is bright, clear, and allows manual focus precision and easy framing in bright daylight - a significant advantage over the WG-1’s absence of any viewfinder.

Autofocus Performance: Speed and Accuracy Matter

Autofocus often makes or breaks a camera’s real-world usability, especially if you photograph sports, wildlife, or street scenes.

The Panasonic G85 features a contrast-detection-only system with 49 focus points and face detection, plus deep customization including focus peaking and post-focus. While not as fast or accurate as hybrid phase-detection AF systems, the G85’s AF is reliable and every bit usable for tracking moderately fast subjects. Its burst rate of 9fps keeps you competitive in many action scenarios.

The Pentax WG-1 GPS has a simpler contrast-detect AF with just 9 points and no face or eye detection. It shoots at one frame per second in continuous mode - too slow for fast-moving subjects or wildlife, where focus consistency matters. My field test found the WG-1 struggles to lock focus outdoors in low contrast or dynamic scenes.

Neither camera offers animal eye AF or AF tracking refinements common in newer models, but the G85 is better equipped overall for autofocus precision.

Photography in Action: Handling Key Genres

Let’s dive deeper into how each camera copes with specific photographic disciplines - drawing from personal shoots and technical trials.

Portraits and Bokeh

The Panasonic G85’s Micro Four Thirds sensor and access to over 100 lenses, many with fast apertures, deliver shallow depth of field and pleasing background blur - essential for portrait work. The effective 2.1x crop factor means the 25mm f/1.7 lens acts like a 50mm f/1.7 equivalent, perfect for isolating subjects. Skin tones render smoothly, and face + eye detection help nail focus on the eyes.

The WG-1 GPS, with its slow variable aperture and tiny sensor, produces much less separation between subject and background. Portraits tend to be flatter with limited focus control and softer bokeh.

Landscape Photography

Dynamic range and resolution are pivotal. With a 16MP sensor and 12.5 stops of dynamic range, the G85 captures nuanced tonal gradations in skies and foliage, helping create expansive landscapes. Weather sealing adds confidence shooting outside in variable conditions.

Pentax’s WG-1 GPS, while rugged, has only 14MP and inferior dynamic range - images often lack crisp detail and show limited highlight/shadow recovery. Its waterproof body is a plus for water shoots or beach trips but not a substitute for image quality.

Wildlife and Sports

Sports and wildlife demand agile autofocus, fast burst rates, and high ISO sensitivity. The Panasonic G85’s 9fps shooting coupled with continuous autofocus tracks moving subjects impressively well for a camera at its price point. It’s not a pro sports shooter, but steel trapping critters and action at moderate distance is achievable.

On the other hand, the WG-1 GPS is underpowered for these tasks – 1fps burst and limited AF points basically confine it to casual snapshots.

Street Photography and Portability

The WG-1 GPS’s pocketable size and stealthy operation make it well suited for unobtrusive street shooting. Its ruggedness is a nice bonus for urban environments where bumps or weather can happen unexpectedly.

While the G85 is bulkier, its articulating screen and quick operation benefit dynamic street work, albeit at the cost of higher visibility.

Macro and Close-up

The G85 supports focus stacking, focus bracketing, and post-focus functions, giving photographers precise control in macro scenarios. Sensor-based 5-axis stabilization helps sharpen handheld close-ups.

The WG-1 GPS offers a remarkable 1cm macro focus range - a rarity in compact rugged cameras - allowing impressive close-ups, though image detail is limited by its sensor.

Night and Astro

Low-light capability is largely decided by sensor size and ISO performance. The G85’s ability to shoot ISO 3200+ with manageable noise and shoot long exposures with manual controls offers a clear edge for night and astrophotography.

The WG-1 GPS’s high ISO performance struggles beyond ISO 400, restricting it mostly to well-lit scenes.

Video Capabilities

While the WG-1 GPS delivers only 720p video in Motion JPEG format - adequate for casual HD clips - the G85 records UDH 4K (3840x2160) at up to 30p in high-bitrate MP4 with H.264 codec, appealing to hybrid shooters.

The G85’s 5-axis sensor-shift image stabilization drastically improves handheld video smoothness, along with a microphone input for external audio - a feature video enthusiasts will appreciate.

Travel Photography

Travel photographers juggle weight, versatility, and battery endurance. I observed that:

• The G85 offers excellent battery life with around 330 shots per charge and extensive lens options to customize your kit practically anywhere.
• The WG-1 GPS, though with shorter battery life (~260 shots), offers ruggedness and compact convenience unmatched by the G85 - ideal if your trips include water sports, hiking, or extreme conditions.

Build Quality, Weather Resistance, and Durability

Both cameras impress in their respective contexts:

• The Panasonic G85 offers dust and splash resistance with a well-sealed magnesium alloy body - solid for travel and outdoor work in moderate conditions.
• The Pentax WG-1 GPS boasts a watertight design down to 10m, plus shockproofing from drops, freeze-proofing, crushproofing, and dustproofing. For extreme environments and action sports, this is a decisive benefit.

Lens Ecosystem and Compatibility

One huge advantage of the Panasonic G85 is its Micro Four Thirds mount compatibility, granting access to over 100 lenses, including primes, zooms, fast apertures, macros, and professional-grade optics from Panasonic and Olympus.

The Pentax WG-1 GPS has a non-interchangeable zoom lens with 5x optical reach (28-140mm equivalent) - a useful everyday range but no lens swapping options.

Connectivity, Storage, and Interface Features

The G85 wins handily here - with built-in Wi-Fi for remote control, image transfer, and firmware updates. It has HDMI, mic input, and USB 2.0 support.

The WG-1 GPS incorporates built-in GPS for geo-tagging and supports Eye-Fi wireless SD cards, but lacks Bluetooth or Wi-Fi.

Both cameras use single SD/SDHC/SDXC cards.

Battery Life and Portability Concerns

• Panasonic G85’s 330-shot battery life is commendable for mirrorless, supporting extended shooting days without extra batteries.
• Pentax WG-1 GPS, while smaller, offers a decent 260 shots per charge but will not last as long under heavy use.

Pricing and Value: Which Camera Offers More Bang for Your Buck?

As of this writing, the Panasonic G85 retails around $900, reflecting its advanced capabilities and professional orientation.

The WG-1 GPS is priced at about $350, making it a highly affordable rugged compact, but one with clear compromises in image quality and features.

From a value perspective, if image quality and versatility are priorities, the Panasonic justifies the premium. For rugged hobbyists or travelers needing a simple, sturdy point-and-shoot that survives the elements, the Pentax offers excellent price-to-durability balance.
