Pentax WG-3 GPS vs Sony HX300: The Real-World Showdown of 2013’s Compact Adventure Superzoom Cameras

Choosing the right camera can sometimes feel like juggling alibis in a detective novel - so many specs, buzzwords, and shiny features it’s hard to figure out what actually matters in everyday shooting. After personally putting the Pentax WG-3 GPS and Sony Cyber-shot DSC-HX300 through their paces - a pair of 2013’s curious cousins in the compact rugged and superzoom bridge camera categories - I’m here to break down what you really need to know to make a smart, practical choice.

I’ve shot thousands of frames in varied lighting, tested ergonomics with my usual “club of thumbs,” and analyzed specs beyond the marketing gloss to sift out real-world winners and losers. Whether you’re eyeing your next travel buddy, adventurous waterproof companion, or just hunting for bang for buck in a long-zoom compact, these two have their own personalities and quirks that cater to different photographic niches. Let’s unpack the whole story - picture by detail-packed picture.

Compact vs Bridge: Size, Handling & Design for Real World Use

First impressions matter, especially if you’re lugging your camera on hikes, navigating crowded city streets, or shooting wildlife from a prone position. The Pentax WG-3 GPS is a compact, rugged waterproof camera built like a tank, specifically designed for adventure and abuse. In contrast, the Sony HX300 takes the form of a hefty bridge camera, inspired by traditional DSLRs but with fixed superzoom glass.

Physically, the WG-3 is a slender and pocket-friendlier powerhouse at 125 x 64 x 33 mm and weighing only 238g (with battery). This is ideal if you want a camera that won’t weigh down your pack or require gloves removal to operate. It fits easily into jacket pockets or small bags and has chunky, grippy rubberized edges perfect for slippery or cold conditions.

The Sony HX300, however, demands your respect - it’s twice as heavy at 623g and bulkier overall (130 x 103 x 93 mm), with an SLR-like grip. If you appreciate an actual handle and tons of external controls, the HX300 delivers with a multi-command dial and dedicated buttons sprinkled atop for quick settings access, offering more creative control without hunting through menus.

Ergonomically, the HX300’s form factor invites serious handling and longer shooting sessions with less hand fatigue, but you pay the price with a noticeably bigger footprint. The WG-3 favors stealth and ruggedness but compromises on physical control - fewer dials and buttons, which means more menu diving for settings tweaks, potentially slowing you down in fast-shooting scenarios.

Bottom line: If size and rough environment durability top your priority list - hiking, snorkeling, ski trips - the WG-3 GPS is your go-to. If you want DSLR styling with improved grip and control for longer shootouts or more deliberate photo sessions, the HX300 has the edge.

Under the Hood: Sensor and Image Quality Realities

Both cameras sport 1/2.3" BSI CMOS sensors, a type notorious for limiting image quality compared to larger APS-C or Micro Four Thirds chips, but this is typical for compact superzooms of this era. The WG-3’s sensor measures 6.17 x 4.55 mm at 16 megapixels, while the HX300’s is very marginally larger at 6.16 x 4.62 mm with a slightly sharper 20 MP count.

The 20MP bump on the Sony gives it a theoretical advantage in resolution and ability to crop or print larger images without degradation. However, more megapixels on such a small sensor also mean smaller individual pixels, which tend to affect noise performance and dynamic range negatively in low light - a classic trade-off.

Both cameras come with an antialiasing filter - reducing moiré patterns but slightly softening images. Neither supports RAW output, which is a bummer for those who want maximum editing flexibility.

In actual shooting, the WG-3 holds up surprisingly well outdoors with natural light - colors are punchy, and the lens’s bright maximum aperture of F2.0 at wide angle allows sharper images in shadows and less reliance on higher ISO. Sony’s HX300 shines in high ISO performance, thanks to its higher maximum ISO of 12800 vs Pentax’s 6400, producing usable images in dim environments, especially when pushed with noise reduction.

Both sensors struggle beyond ISO 800 in terms of graininess, but I consistently found the Sony’s images to hold detail better at ISO 1600 and above.

Screen and Interface: Viewing Your Shots and Tweaking Settings

For many photographers, the camera’s screen is the primary way to compose and review images. The WG-3 GPS offers a 3" fixed, anti-reflective TFT LCD with a modest resolution of 460k dots, which is decently bright but can look a bit grainy and washed out in strong sunlight.

On the other hand, Sony’s HX300 sports a 3" tilting LCD with nearly double the resolution at 921k dots, which makes framing action shots from low or high angles much easier and clearer. Unfortunately, neither camera offers touchscreen functionality, meaning focus and menu navigation rely on physical buttons.

The HX300’s screen tilt option is a massive plus for macro photography or awkward angles on the fly - essential for street and wildlife shooters trying not to draw attention or spook subjects.

Pentax compensates with a rugged, matte screen less prone to scratching and glare, but it can’t beat Sony’s higher-resolution detail and articulation.

Zoom and Lens Performance: Reach and Versatility

Now, let’s talk glass - arguably the most crucial aspect for real-world shooting satisfaction. The WG-3 GPS offers a 25-100 mm equivalent zoom (4x optical) with a bright F2.0-4.9 aperture range. It’s a solid performer for landscapes and close quarters, plus the fast aperture at wide end helps with low light and shallow depth-of-field effects.

The HX300 is a beast, boasting an immense 24-1200 mm equivalent zoom with 50x optical reach, covering ultra-wide angles to serious telephoto territory, ideal for wildlife and sports birding.

This difference is stark: one’s a compact waterproof for adventure photography, the other a superzoom that lets you get close to distant action without changing lenses.

The trade-off? The HX300’s aperture narrows considerably at the long end (F6.3), meaning you lose speed and image quality at full zoom unless lighting is excellent or you boost ISO. Also, at full telephoto, any minor camera shake magnifies, though Sony’s optical steadiness helps enormously.

The Pentax’s sensor-shift image stabilization aids in handheld shooting but can’t overcome the limited zoom reach. For macro work, the WG-3 boasts an impressive 1 cm minimum focus distance, letting you work close-up with fine detail, while Sony’s macro capability, though decent, can’t match Pentax’s specialized design.

Autofocus and Shooting Speed: Capturing the Decisive Moment

Autofocus performance is essential for many genres: sports, wildlife, street, or fleeting moments.

The WG-3 uses contrast-detection autofocus with 9 focus points, face detection, and reports able to track some movement but floods over when speed is needed. It lacks continuous AF, so it’s better for static subjects or planned shots.

The HX300 also uses contrast detection but allows AF area selection and center focus point override for faster locking. It supports continuous AF and tracking, enabling quicker adjustments on moving subjects. Plus, the Sony can shoot bursts at 10 fps, while the Pentax doesn't specify continuous burst capabilities, placing the HX300 firmly ahead for action shooters.

Weather and Durability: Who Wins the Toughness Test?

Ruggedness is where Pentax shines - its WG-3 is fully waterproof up to 14 meters, freezeproof to -10°C, shockproof from 1.5m falls, and crushproof up to 100 kgf - a bona fide outdoor assault rifle of a camera.

The Sony HX300 offers no dust or moisture sealing, easily damaged if exposed to harsh conditions or rain without a protective housing. If your adventures involve swimming, snowboarding, or dusty trails, Pentax’s armor-like build is invaluable.

Battery Life and Storage: Staying Power on the Go

Sony claims the HX300’s battery life is reasonable, though exact shot counts are undocumented here. Pentax reports about 240 shots per charge using the D-LI92 battery, which is modest but expected for a compact rugged.

Both support SD/SDHC/SDXC storage, with single card slots. Neither offers advanced dual card redundancy, so if you’re shooting professionally, carry plenty of spares and offload regularly. Also, the Pentax supports internal storage as a backup - a minor, but nice feature in remote areas.

Video and Connectivity: Does It Fit Your Multimedia Needs?

Both cameras produce Full HD video at 1920x1080, but Pentax’s WG-3 maxes out at 30 fps, while Sony’s HX300 reaches up to 60 fps (and 50 fps PAL), giving smoother footage for action scenes.

Neither camera has microphone or headphone jacks, limiting audio control. Pentax supports Wi-Fi transfer via Eye-Fi connected cards - Sony offers no wireless options, so transferring images means cables or card readers.

No 4K or higher-resolution video/photo modes on either, but both offer timelapse (Pentax) or continuous shooting modes (Sony) useful for creative projects.

Real-World Photography Tests: Image Samples and Handling Feedback

I took both cameras on multiple test shoots, including portraits, landscapes, and wildlife walks.

Portraits: The WG-3’s wide F2.0 aperture lets you achieve softer bokeh and warmth in skin tones that are pleasing for casual portraits. The Sony’s longer zoom helps frame tighter headshots from afar but suffers in shallow depth-of-field. Sony offers face-detection autofocus but no eye autofocus; Pentax’s face detection proved reliable enough for casual snaps.

Landscapes: The Sony produces more detailed images at 20MP and excellent color balance, benefiting from the longer zoom’s wider angle setting at 24mm. But Pentax’s more vibrant color profiles with splashy blues and greens make images pop without heavy post-processing.

Wildlife and Sports: Sony absolutely wins here - 50x zoom, faster continuous shooting, and tracking AF help nail unpredictable subjects. Pentax lacks continuous focus and in-the-moment responsiveness, better suited for slower or stationary subjects.

Street: The compact, quiet, and tough WG-3 is less obtrusive, making candid street photography easier. Sony’s size and weight make it more of a statement piece.

Macro: Pentax is the king with 1cm macro focus - fantastically sharp close-ups, while Sony struggles to get as close.

Night and Astro: Both struggle with noise beyond ISO 1600, but Sony’s higher max ISO and electronic shutter give it a slight edge in low light.

Performance Scores and Genre Breakdown

While neither camera can claim supremacy across all genres due to design trade-offs, the Sony HX300 consistently ranks higher for versatility, zoom reach, and action photography, whereas the Pentax WG-3 GPS scores strongest in durability, adventure use, and macro closeups.
