Pentax WG-1 GPS vs Sony QX30: A Hands-On Comparison for the Discerning Photographer

Over my 15+ years testing digital cameras, I have encountered a fascinating range of compact devices designed for different types of users and use cases. Today’s head-to-head comparison is between two very distinct cameras: the Pentax Optio WG-1 GPS, a rugged waterproof compact announced in 2011, and the Sony Cyber-shot DSC-QX30, a 2014 lens-style camera designed to connect with your smartphone. Both cameras retail around the same price point (~$350) but aim to solve vastly different photographic challenges.

Having personally tested both models under varied conditions, from hiking rugged landscapes to urban street scenes and casual travel snapshots, I am excited to share an in-depth, practical review that goes beyond specs sheets. This article will peel back their technical underpinnings and real-world performance, helping you make an informed choice based on your photographic ambitions.

Facets of Design: From Rugged Compact to Smartphone Lens

At first glance, these cameras couldn’t be more different physically and in intended use cases.

The Pentax WG-1 GPS is a traditional compact: boxy but ergonomic with dedicated buttons and a built-in LCD screen. In contrast, the Sony QX30 is a lens-shaped device without a screen or a physical body – designed to mount on or work wirelessly with a smartphone (which becomes the viewfinder and controls). This unique design fundamentally changes how you interact with the camera.

Holding and operating the WG-1 GPS feels solid and reassuring in the outdoors, with a grippy textured body. The fixed 2.7-inch LCD, while modestly resolved, is perfectly serviceable in bright daylight thanks to its anti-reflective coating. Conversely, the QX30 is ultra-compact, almost pocketable, but relies entirely on your smartphone’s touchscreen for framing and adjustments. This makes it highly versatile but demands a compatible device and more setup.

Control Layout and User Interface: Physical Buttons vs Touchscreen Command

The operational experience of these cameras couldn’t be more distinct.

With the WG-1 GPS, everything is handled via physical controls - a boon when wearing gloves or navigating in wet environments. It features a straightforward interface, with a dedicated record button for video, a zoom rocker, and easily accessible shooting mode toggles. The menu system is simple, though lacks some advanced exposure controls.

Sony QX30, by design, has no physical controls aside from a shutter button on the lens barrel. You rely entirely on the smartphone app for focus, exposure mode, image review, and even zoom control. This means fast manual adjustments require fluency with the app interface and a stable Bluetooth/Wi-Fi connection. The touchscreen autofocus with face detection in the app is impressively accurate but takes some getting used to.

If tactile buttons and immediate physical control matter to you, the Pentax wins here hands down. For smartphone users wanting a minimalist camera attachment, the QX30’s innovative concept may tip the scales after a learning curve.

Sensor and Image Quality: Bright Pixels or More Megapixels?

Despite sharing the same sensor size of 1/2.3" (6.17 × 4.55 mm sensor area), Pentax and Sony take very different paths in sensor technology and image processing.

The Pentax WG-1 GPS houses a 14MP CCD sensor, while the Sony QX30 uses a 20MP BSI-CMOS sensor paired with Sony’s potent Bionz X processor. The CMOS sensor and advanced processor generally yield better noise control, dynamic range, and color fidelity.

In controlled indoor and daylight tests, the Sony QX30 produces noticeably sharper and more detailed images with less noise at higher ISOs (up to ISO 3200). Pentax struggles beyond ISO 400, manifesting grain and softer details. Both cameras apply an antialiasing filter, modestly smoothing fine textures, but Sony’s sensor resolution advantage is evident.

Color reproduction is pleasing on both, but the QX30’s face detection and superior processing deliver better skin tones and natural hues under mixed lighting - an important factor for portrait and event shooters.

Working the Scene: AF Performance and Autofocus Technologies

Autofocus is a critical determinant of whether a camera keeps pace with fast-moving subjects or fleeting moments.

Pentax WG-1 GPS employs a contrast-detection AF system, with 9 focus points and center-weighted metering. It’s fairly slow and prone to hunting - especially in low light or low contrast scenes. The lack of face or eye detection limits its effectiveness for portraits or people photography. Continuous autofocus and tracking are not supported, and burst mode is a sluggish 1 fps.

Sony’s QX30 is also limited to contrast-based AF but enhanced with touch AF on the smartphone screen, face detection, and spot metering options. While it lacks phase detection and continuous AF, the ability to tap-to-focus combined with a faster shutter uptime (10 fps burst mode) allows for greater success capturing dynamic subjects.

For wildlife and sports photography, neither camera is ideal due to their AF and frame rate limitations - but Sony’s QX30 is the more capable option for those occasional action shots.

The Ergonomics of Viewing and Composing

Since the Pentax WG-1 GPS features no electronic viewfinder, the 2.7-inch LCD is the only visual tool. Its 230k-dot resolution is decent but fairly low by modern standards. The screen’s fixed angle sometimes hinders shooting from low or high perspectives, but the anti-reflective coating helps outdoors.

The Sony QX30 has no built-in screen or EVF, operating exclusively via a smartphone’s display connected over Wi-Fi. This has pros and cons: you get better framing flexibility - any tilt or swivel angles limited only by your phone - and touch focusing, but you're tethered to your phone’s battery and connectivity.

If you favor quick one-handed operation with stable framing, the Pentax may be more accessible. For experimental or social sharing in real-time, Sony’s wireless interface opens many creative possibilities.

Built to Take a Beating or To Stay Sleek?

Durability is a key consideration depending on your shooting environments.

Pentax WG-1 GPS is designed from the ground up to be tough: waterproof to 10m depth, shockproof from 1.5m drops, freezeproof to -10°C, crushproof under 100kgf, and dustproof. Such ruggedness is rare and invaluable in outdoor, adventure, and underwater scenarios.

Sony QX30 has no explicit environmental sealing - its lightweight plastic build and exposed electronics mean it’s best kept out of harsh weather, dust, or water exposure. This limits outdoor or travel use in demanding conditions.

If you are an avid hiker, beachcomber, or thrill-seeker who shoots in rugged terrain, the WG-1 GPS’s toughness offers peace of mind unmatched by the QX30.

Zoom Ranges and Lens Considerations

Both cameras boast superzoom fixed lenses, but with notable differences:

• Pentax WG-1 GPS: 28-140 mm equivalent (5x optical zoom) at F3.5-5.5
• Sony QX30: 24-720 mm equivalent (30x optical zoom) at F3.5-6.3

The Sony QX30’s massive zoom range is one of its standout attractions, allowing you to reach faraway subjects without carrying a bulky setup. However, at extreme telephoto, expect some softness and chromatic aberrations typical of long-zoom lenses on small sensors.

Pentax offers wider angle coverage at the short end, which suits landscape and street photography better. It also features a macro focus range starting as close as 1 cm, letting you get creative with close-up shots.

Image Stabilization Matters

The Sony QX30’s optical image stabilization (OIS) is a major plus, especially given its enormous zoom range. In my handheld tests, OIS made a real difference in producing sharp photos at long focal lengths and slower shutter speeds.

The Pentax WG-1 GPS lacks any form of image stabilization, which can make shooting hand-held telephoto or in dimmer lighting prone to blur unless you boost ISO or use a tripod. This is a notable limitation, especially for sports, wildlife, or low light scenarios.

Video Capture and Usability

Videographers among you may find the Sony QX30 more appealing, as it shoots Full HD 1080p video at up to 60fps in MPEG-4 format - a respectable offering for casual video creation.

Pentax WG-1 GPS caps out at 720p HD video at 30fps in Motion JPEG format, which is dated and chunkier in file size. The lack of manual exposure controls and audio input ports on both cameras limits serious video production, but Sony’s smoother frame rates and higher resolution provide more flexibility.

Battery Life and Storage

The Pentax WG-1 GPS uses a proprietary D-LI92 battery with about 260 shots per charge - decent but not exceptional given the compact type and rugged design.

Sony QX30’s NP-BN battery offers around 200 shots per charge, slightly less than the Pentax. Because the QX30 relies on your smartphone for controls and playback, actual power consumption depends heavily on your phone’s wireless usage as well.

Regarding storage, the WG-1 supports full-size SD cards, including SDXC, which can be easier and faster for larger files. Sony QX30 uses microSD and Memory Stick Micro cards, which are more compact but may limit speed or capacity options.

Connectivity and Wireless Features

Both cameras offer wireless capabilities but in totally different forms:

• Pentax WG-1 GPS includes built-in GPS geotagging and Eye-Fi support for wireless images transfers. This is great for adventure photographers wanting location data embedded in their images.
• Sony QX30 depends on built-in Wi-Fi and NFC connectivity for pairing with smartphones. This seamless integration lets you easily share shots on social media via your phone or control zoom and focus remotely.

If geotagging is critical to your workflow, Pentax scores here. For smartphone-centric shooters who prioritize instant connectivity and sharing, Sony’s lens-style design enjoys the edge.

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

At their launch prices - both hovering near $350 - the selection here boils down to prioritizing ruggedness and simplicity (Pentax) versus zoom flexibility and smartphone integration (Sony).

Despite the Sony QX30’s technological edge in sensor resolution, autofocus assistance, and optical stabilization, the lack of environmental sealing and reliance on a smartphone might not suit everyone. The Pentax WG-1 GPS’s unique toughness and easy-to-use physical controls stand out as an all-weather, ready-to-go companion.
